  1. Hello, Just don't have the time and my job push me very far from my home. For example, now I'm in Tanzania and I'm French. I know everybody is waiting for me, please be patient, life is not an hobby. Two of my own friends are waiting for this since a long time, sorry for that. Some link are missing for sure but it's not a fake one, Ephteca can tell it, I sent a full kit to Thorsten too, but I think he didn't take the time to build it, maybe he has a job too ;) I promise that i will continue this project, this is a priority for my next holidays. The list - Mat x1 - Djo x1 - Mrspring - Yogi - Scrubber Fox - Thumper - Academic Planner - Me x3 Best regards
  2. http://www.bbc.com/news/entertainment-arts-27187582 A lot ofbox for our synth LOL
  3. Hi, ??? I don't understand
  4. I can fab for you PCB+PIC and Backplane? <50Euros Who is interested to build his own Synth in cartridge version? Already in list:- Mat x1 - Djo x1 - Mrspring - Yogi - Scrubber Fox - Thumper - Me x3
  5. hi Thumper, Led bargraph is not real one, i mean this is not a sampling and integration of the audio signal, there's two volume registers in the TIA drived by the PIC, i just use this value, one bar by register with 4 thresholds which lit the leds. This Volume (AUDV0 and AUDV1) registers are 4 bits, so 16 level. for each register so: first led on when 0x01 =< AUDVx <0x07 first, second led on when 0x07 =< AUDVx <0x0b first, second, third led on when 0x0b=< AUDVx <0x0e all led on when 0x0e=< AUDVx inc file attached led handler is called on AUDVx change. Simply that's all tia_led_meter.inc
  6. I tried it but without result, for now my processus cycle don't need it, but i'm ears too for later. I think we've got to manage ADC the request, ADC as source, Mem as destinations with some others obscurs parameters. First, DMA configuration depends on the source, Extenal ADC (I2S, SPI) or Internal ADC... Mine is internal ADC. For you? I configure and run under DMA but my problem is that i don't understand the request system, i just understand that bust mode is to read ADC Channels sequencially in opposition of single mode... Someone?
  7. Hi, thank you for your answer, it's clear now and will be helpfull! :) An other question did you try to use DMA with the ADC? BR
  8. Hi MidiSaron, I find in your dokuwiki that you use the AN10913 DSP library, i need it too. How did you add it? in details, please... BR
  9. Hi everybody i will print some boards and backplane (cartridge version) for some friends and myself. - Mat x1 - Djo x1 - Me x3 The cartridge version: Who should be interrested? I can solder and burn the pic for you, cause it's an smd package. To you to find your atari 2600, a game cartridge, connectors and others common components Already in the list: - Mrspring - Yogi - Scrubber Fox Sorry guys when we talk about i forget the backplane which is about 15€ Tell me! And will calculate the effective total cost, but board + pic + backplane + shipping will be less than 50 €
  10. Hi Yogi sorry for wrong link! This is thé full project folder https://docs.google.com/folderview?id=0B8IO3f-Xz3O4ajhTMTRvRUhtNTA&usp=docslist_api With firmware ðŸ˜
  11. You're right! Like the SID box it's à standalone and full synth. See dokuwiki for midi implemention chart. I was very frustrated with synthcart, no sync, large tempo step, no midi... That´s the reason why I made It ;) I visit your site and watched your vidéo mix, i like It!
  12. It works? Don't understand what it happened... you flashed your 4685 with a 452 bootloader ?
  13. Connect midi in and out ;) Quit mios studio and reopen it. Reconnect your midi interface. PC or Mac? Maybe reburn the bootlader and verify your circuit... You're now a midibox explorer ;)
  14. just to be sure, you have already FLASH the pic with the bootloader flile "bootloader_v1_2b_pic18f4685.hex" ? (BURN!) ... what does it say when you load "mios_v1_9g_pic18f4685.hex" via midi in mios studio? This hex is necessary before send all other firmware. ... The base hex is a third layer!!! And please just to be sure of your tia base circuit, follow the tests interconnection and testtone steps before the final base firmware load... remember you've got to burn bootloader hex and send TWO hex, the MIOS first and the application firmware after...
  15. First layer: Bootloader 1 - flash the PIC with the bootloader. (another Hex file in the MIOS zip)` Second layer: MIOS 2 - now ready to load the MIOS. in midi with mios studio. Third layer: FW 3 - test register pinout, with http://www.midibox.org/dokuwiki/lib/exe/fetch.php?media=mbtia_interconnection_test.zip and without the TIA onboard. 4 - test the TIA with http://www.midibox.org/dokuwiki/lib/exe/fetch.php?media=mbtia_testtone.zip, you will hear it. 5 - load the mb TIA base FW.
  16. Hi Srubber, This modification is on the Mb SID V2 page. Here the information you need: http://www.ucapps.de/midibox_sid/mbsid_v2_communication.pdf For the hex, both is impossible ;) the 'base' is the one for you cause you follow the base schematic, 'cartridge' if for the cartridge version only... ...
  17. Hi scrubber, Eptheca is right just à resistor is necessary to adapt your core for the 4685. No 452 cause no enougth memory space. Display and CS have to be implemented, no CS on my firmware ;) And i want to watch your too, yes yes yes!
  18. I know that Eptheca find an usb flasher on ebay for a good price... Ask him, maybe ;) http://www.ebay.com/bhp/usb-microchip-pic-programmer
  19. Yes it is ! Voices page: Mods page: :thumbsup:
  20. Eptheca is right on a PAL pin 12 is for video carrier, don't use it! The two voices Aud0/Aud1 are mixed internally and outputted on pin 13. A0/A1 (pin 31/32) are the LSB adress bus and must be connected to the shift register. I made a mistake on the schematics, the blue jumper is on A1/R2 for PAL one, sorry.
  21. Oh i forgot to say that the manager is iPad ready! Just download c74 app from your app store.
  22. Hi Scrubber, You will find it on the Cheers
