Title: SE-ONE music file player
Post by: gflorez on 2018.April.12. 10:13:28
I have connected an I/O MSX cartridge named SE-ONE (http://www.tmtlogic.com/tmtlogic.com/index.php/umja/msx-se-one-mp3-player), from TMTLogic (http://www.tmtlogic.com/tmtlogic.com/index.php), and it has been correctly detected by the EDCW hardware searcher:

Sorry for the ugly picture....

It is a MP3 player and FM receiver that can be easily accessed from Basic by AT commands.

This is my "bad looking" MSX slot prototype:

[attach=1]

I had a silly error making the bus expander, so I have to repeat the PCBs. It works, but only if I solder the edge connectors on the PCB bottom side..., by mistake I swapped the slots's As and Bs pins....

But meanwhile these fault PCBs can be perfectly used to test the MSX slot.

The cartridge still doesn't give sound, I have to add the +12/-12v converter. By now I am using the 4MHz processor clock. Later I will add the 3,579545MHz clock generator.

Now I have added the +12/-12v converter.

The module brings by default an intro tune that plays every time the cartridge restarts. The MSX line of computers where designed mono only, and so the cartridge has only a pin for input sound. This SE-ONE cartridge has Stereo output, of course, but only returns the left channel by the slot pin and stereo by the 3,5mm jack at the upper side.

By now I have only connected the left channel to the Enterprise, and I have been pleasantly surprised at how correctly the sound has been mixed and balanced with the Enterprise internal sound.

200 LET L = LEN(AT$)
210 IF L = 0 THEN GOTO 180
220 FOR T = 1 TO L
230 LET S = ORD(AT$(T:T))
240 OUT 32,S

On 2 months TMTlogic will be selling V9990 MSX graphics cartridges from Holland. No need to buy them on Brazil....

Tim even has proposed to build similar specific Enterprise Hardware if more than 20 units are done.

His last creation is a SE-ONE MP3 player for the CPC (http://www.tmtlogic.com/tmtlogic.com/images/SE-ONE/CPC/SE-ONE-CPC-2a.jpg) computer range.

Hans, from TMTLogic says that a SE-ONE for Enterprise would cost about 59 Euro.

But the problem here is that it would need some form of bus expander, if you already have an EXDOS  controller, Spectrum emulator, or other cards.

Here you have a better video:

https://www.dropbox.com/s/aboo3t0gd4n4ajh/Enterprise%26ES-ONE.mp4?dl=0

The sound is very bad, my tablet saves very low the sound, and the monitor produces an annoying noise. You will notice that the SymbOS Radio app shows corrupted its graphics, but it is because it was programmed for a 16 colour palette.

Yessss! it opens a new unexplored way on Enterprise hardware. Observe how there aren't chips on the prototype, the electronics have been bypassed. The only ad-on is the 7805 regulator to produce +5v, and later a +5v to +- 12v converter. All the other leads connect directly to the correspondent Z80 bus Enterprise signals.

The magic here is how Prodatron has left (intentionally?) MSX code to access the device on the Enterprise port of SymbOS.

Also, the sound is injected directly to the Enterprise and it mix the stereo sound accordingly with the internal sound. What you hear is the Enterprise output sound.

One problem we, owners of Enterprise computers, suffer, is the "shortage" of hardware developers. This prototype proves that we can take advantage of other computer's hardware, and the MSX community is very active....

Now we are very near to enjoy a Yamaha V9990 graphics cartridge on our loved computer. Will it continue being an Enterprise? Probably! if someone creates an EXOS driver for it...

Don't you dream about a MIDI interface on the Enterprise....?

In this ugly video I launch a song reproduction with an AT command, and then the SE-ONE plays it until I send the Stop command.

This time the mp3 song is read from the cartridge USB port, totally autonomous.

Playing on SymbOS, on the other clips it can be, as it is reading from the SD card, but reading from its USB it sounds continuous. I have tested the last video on two computers and there aren't pauses.
Title: Re:SE-ONE music file player
Post by: gflorez on 2018.April.17. 13:35:20
Maybe  you refer a pause when I click on the NEXT SONG button on the SymAmp player? It is closing the actual mp3 song and searching the next song in the SD.

Observe how the mouse pointer manages the player.

I am discovering new uses for this little beast of cartridge. I am finishing the translation of the minimal SEplayer from MSX Basic to Enterprise Basic. Soon I will show a new video.

It actually plays the following files: MP3, AAC, OGG, WAV, WMA, MP4(audio), and surprisingly MID(Type 0, probably with a modifiable instrument table... ). The Basic program works as a simple DOS command interpreter, you can make a sort of DIR and select the name of a file to play from the cartridge USB port. You even can change the path, enter or leave a directory on the pen-drive disk tree. All made with AT commands on an easy basic listing...

Initially the SE-ONE was designed to also have a MIDI interface, but Hans says that the MSX community showed little interest and it was dropped from the final design. It is reasonable, as there are a lot of classic commercial MIDI cartridges  for the MSX range of computers, and a lot of projects made by users. On the other side there is no popular software to manage it.

But Hans says that the UART port was left as a header for communicating with the  Arm processor, the hearth of the cartridge, so he proposes to add the MIDI interface idea on a eventual Enterprise SE-ONE cartridge. This, he says, will need a software to be programmed on the Enterprise side....

Another curious application of the cartridge is as a speech synthesizer, an emulator of the SP0256-AL2, exactly the same chip inside the Enterprise Speakeasy interface.... Allophones can be sent to the cartridge by means of an AT command.

He is now hard working on a DAB+(digital FM radio) receiver for the SE-ONE. Once finished he will send me the schematics to add the MIDI interface to the cartridge.


As you can see this concept cartridge is constantly evolving and being improved.

Hello Hans. Here I am emulating your work with your CPC AMSDAP , trying to build an interface with MSX slots for the Enterprise, but as a side effect showing the wonders of your SE-ONE cartridge, the first and only module I have tried on my prototype....

Is the first time I know that the software(SymAmp by Prodatron) is made before the necessary hardware. You launched the cartridge on summer 2017, but we have the SymbOS Enterprise port for several years now... 

Well, the secret is that SE-ONE is a clone of a MSX Sunrise mp3 cartridge from the 90s.... and Prodatron leave code inside the player to manage that old MSX I/O cartridge. But now you have added some new lovely tricks like the FM receiver.

The clever idea of the AT commands is another of your innovations, and allows all the characteristics of the module to be managed from any high level language interpreter almost from the first time it is inserted on the slot. It is demonstrated with the previous simple Basic listing.

I am still discovering new treasures....

Infomation about the SE-ONE can be found at www.tmtlogic.com.

If more than 15 people are interested in an enterprise version of the SE-ONE, I can make this card for you.

Price will be approximately € 59. (exlc shipping cost from the Netherlands)
If a midi interface needs to be added, the price will rise.

Thanks to gflorez for making the msx to enterprice adaptor !

MSX SE-ONE version  is normaly enough in stock.

There is also an SE-ONE for the CPC computer

This is really amazing!
Anyway, you can make the printing faster using OUT 191,12 and POKE 56,201. However the latest stops the interrupts. Switching them on again: POKE 56,245. Or, if you use separate video channels and switch between them using DISPLAY command you can save the time of printing the text again, it would be faster.

Anyway, won't you have an own Youtube channel? Uploading and playing the "dirty" videos would be easier.

I have asked Hans about how powerful is the Arm processor inside the SE-ONE cartridge...

Because I have an idea, and when I think.... an heavenly cherub loses his wings or a lovely kitten dies....:

How about to use the Arm processor as an Enterprise  coprocessor?

He has answered: "400MHz....., in excess to do the MP3 decoding, and yes, it is possible to pass it  functions to calculate on its serial RAM(?) by AT commands". But he adds: "I will study some way to do it faster".

I think:(I don't know if this Arm processor has a FPU, but at 400MHz it can give a boost to the Enterprise mathematical functions....)

Then I start to digress  about AM9511A emulation, or better, 80287 emulation on BCD mode....

And Hans says: "can you give me a C code listing of that?"....

Title: Re: SE-ONE music file player
Post by: gflorez on 2018.May.18. 09:34:25
Directly.... It gives good sound without distortion.

And the Enterprise seems to mix it perfectly with the internal sound.
Title: Re: SE-ONE music file player
Post by: pear on 2018.May.18. 10:07:49
This is not the point.
On my FlexiBridge I made a mini jack for audio input.
I predicted the possibility of its protection against applying too high voltage.
I need to know how much it is "too high voltage".
Title: Re: SE-ONE music file player

Title: Re: SE-ONE music file player
Post by: pear on 2018.May.18. 10:47:56
From the scheme we can deduce what is the level at the output.
At the input it should definitely be below 5V, but for audio it's still too much.
It's hard to say, does DAVE have any security inside ?
In general, the external audio input circuit in EP is strange because it does not cut off the fixed voltage.
I would be careful.
Title: Re: SE-ONE music file player
Post by: gflorez on 2018.May.18. 11:31:17
If you describe me the way to measure that level with a multimeter, I can do it.

Sometimes I  notice a small downing in the volume on some higher parts of the songs, the transitions are very smooth, so they don´t interfere with the listening. After that high point, the volume slowly returns to its initial state.

But probably in my specific case this correction is done on the TV amplifier input, not inside the Enterprise, because the mixed sound is very clear on all instances.

For me the effect is very similar to the auto-level that the tape recorders incorporated from mid 80's.

I have to try the same song section with other monitors or amplifiers.

Post by: pear on 2018.May.18. 11:37:33
Set the multimeter to measure the AC voltage.
The MAX measurement function would be useful.
The input signal set at maximum, but no overdrive.

The effect you describe may ba a change in the signal's constant voltage.
The change will not be heard in the form of some sound, but it will change the parameters of the amplifier's operation (change of volume).

On idle the voltage remains at 0,002v, and on the higher peaks of a song it rises max to 0,350v. It changes fast... but I have not seen a 0,4xx figure.

Not so great.... the Microsoft Basic from MSX is different enough to be a problem.

On the other side, our IS- Basic has more power although slower, but the Enterprise has a lot of tricks to make it better, like video channels, that allow us to manage several screens and  interchange them immediatelly.

Title: Re: SE-ONE music file player
Post by: gflorez on 2019.February.10. 00:58:09
Hello Edoz!

Yes!  It was me, gflorez.

I contacted (https://www.msx.org/forum/msx-talk/software/are-people-here-using-the-radio-app-in-symbos?page=1) you on MSX.ORG.

I showed you a video (https://www.youtube.com/watch?v=muLnypBey6M) of my first prototype of M-Slot (MSX cartridge adapter for Enterprise).

In it you can see how the SE-ONE cartridge is controlled from the SymAmp and Radio applications.

But, being the Radio app made for more than 4 colours, the graphics are displaced.

As you probably know, Prodatron is making tests on the Enterprise SymbOS port with several MSX cartridges, including the SE-ONE and GFX-NINE.

It will be great if you make your Radio app 4 colours compatible.

Thanks.

Sorry for my lazy response on your questions. Very nice to see that it was working! The radio-app i did was "desgined" for 16 colors as i never could think that the hardware would be working on a Enterprise machine! That is crazy! I will try to do my best to see if  can change it and have it work for 4 colors as well! .. if the gfx9000 is working at least you can see it in 16 colors as well :D :D

I have fixed some errors on the SEPLAYER above.

I have tried the Zzzip compiler, it pass correctly the 4 phases and creates the two files.

But when I try to Run, it hangs. It even doesn't finish to modify the SEPLAY2.ZIP to its final shape of only two lines.


Please, what I am doing bad?

Some fixes on the program. The presentation is still dull, but now a complete directory of songs can be played in a loop, and the joystick serves to advance or go back in the loop.

The Intro.mp3 file is  a short introduction played while the two windows are written in the background. It has to be placed on the root directory of the pen-drive on the SE-ONE USB.

Hans has published an interesting but short video of how the SE-ONE started as a clone of the Sunrise mp3 cartridge:

https://youtu.be/OQF_67QSvJA

On the screen you can see a dull MSX app from the 90s era to test the files.

This was 2 years ago, now the SE-ONE has been integrated on the SymbiFace3 for CPC,  ready for its release probably before the summer.

But the development is not on idle on the other 3 computers that support SymbOS. Soon I will be gifted by Hans with a SymbiFace3(CPC) to make the first tests of connection to an Enterprise. Only I/O, because the memory pagination systems of the two computers are very different.

I have said 4 computers supported by SymbOS, don't forget the Amstrad PCW (http://www.habisoft.com/pcwwiki/doku.php?id=:es:start) or Schneider Joyce, a CP/M native machine that  was widely sold on the 8 bit era mainly as a text processor.

The guru of the PCW is Habi, a spanish friend, the guy who created a colour input (https://enterpriseforever.com/display-54/external-colour-tests/) for Enterprise in only an hour.... Not the first,  that was Balaguesz.

As you know, Prodatron pursues the hardware convergence of the four computers. It happened  that Prodatron knew about Habi, but didn't have a contact from him. Then I asked Habi if he wanted to join  the SimbiFace development group, and he acceded.

Habi has already designed a MSX slot adapter for the PCW as a first step. I will aid him to beta-test it.

SampleBox.

New function added to the SE-ONE. A number of sample files can be defined to sound when an event is triggered, like a key or joystick movement.

This Basic example program shows how a key can be associated to a MP3 file. When the same event is found the execution is stopped and started again.

https://youtu.be/pG96MirymfI

Once defined the file name, the sample is launched with only three OUTs:  "OUT 38,0: OUT 39,N: OUT 38,128"

The samples must be placed on the SAMPLE directory at the root of the pen-drive.

Edit: I have added the files, just in case....

One of the lovely functions of the SE-ONE is the FM receiver inside it. As some of you know, there is a SE-ONE on every SymbiFace3, but it lacks the FM chip.

Hans has added it on the next RSF3, so some tests and development have started.

Do you remember the SymbOS FMradio MSX app that worked straight (https://www.youtube.com/watch?v=muLnypBey6M) on my EP+SE-ONE?

ok, ugly graphics, but Edoz has resumed the development adding 4 colours graphics, and now it looks like this:

And this is the 16 colours graphics with the GFX-NINE cartridge output, on the CPC, but it is the same on EP.

it is possible to hack that chip to the existing SF3?

I don't know... Ask Hans. All in SF3 is managed by I2C, so it is "possible", but I imagine that the SF3 lacks the code to manage the FM module. Easy for him to add it...
Title: Re: SE-ONE music file player
Post by: gflorez on 2021.October.08. 00:50:21
Hans has answered, not discouraging me at all.

Connecting more I2C modules is possible, and there is an easy place to connect them, the OLED display.

He also has shown me This (https://www.youtube.com/watch?v=yp0HVGjakMs) video. The device is the same FM chip, but still better, it has an amplifier incorporated. It could give sound externally, but not through the SF3 to the internal EP mixer.

I think it is a feasible option but.... needs some time to implement and test the software to control it, as it is not only like to copy the available SE-ONE or RSF3 code to the SF3.

Now all Hans' time is for the RSF3, but maybe on a future....

Just a off topic question: In Spain need to pay big extra tax for everything which are come from EU outside?
In Hungary +27% for everything, plus few euros cost of tax procedure... (from 2021 July)
Additional frustrating thing: UK now EU outside... f...k Brexit!

Even before Brexit the UK did not have this tax for small things sent from China. If you import something expensive you could be asked to pay a big import tax before you could receive it, but little envelopes from China no problem. I'm not sure what the exact rules/limits are though, or maybe it is just get lucky/unlucky.

The change is EU-wide and was introduced because:

"the current rules have given an unfair advantage to non-EU traders, while e-commerce has been growing."

I remember years ago some of you Hungarians to talk about such tax put by Orban to protect your inner industry. Or maybe I am wrong...

In Spain we can buy cheap things without taxes from third countries, but less than 20€.

More than that price and we have to pay a 21%tax(VAT), but they include the shipping on the price... I think it is an injustice.

Usually they also intent to make us to pay for the customs management, a process that is free if done by oneself.  



Some sellers on third countries allow to pay fixed customs on origin. Such option is a lot cheaper and doesn't stops the packet at customs.

But probably this will not impede the agents to add the Hungary 27% tax over it.

I am not contrary to taxes, I think that fair taxes correctly managed make a Country grow and the citizens happy.
