Sasha Posted November 23, 2007 Report Share Posted November 23, 2007 This is one cool open source AVR project I stumbled across today while browsing AVR Freaks projects. FEATURES: * Works with most cards, max size is limited to 2GB (but please also note, cards 32MB and below could use FAT12, which is not supported) * Real MIDI files on FAT16 (Midi format 0 only) - recording (only root dir) and playback * Maximum of 255 files per folder* * Displays the file names - long names are supported - filename scrolling* * File delete is possible (it can delete any file from the root directory) * 256 byte input/output buffer and 8MHz clock for high performance and precise MIDI timings * Lyrics are displayed (when contained in MIDI file) - cool! * Variable speed (+/-15 steps) and transpose (+/-24) while playing a file * MMC/SD card bootloader - just format a card, copy generated MM.BIN onto it, insert it and switch ON! * MIDI channel mute for each channel * Menu for setting up drum channel, lyric display, repeat modes, channel mutes and track delay* * Settings are stored in non-volatile EEPROM on-chip * IR remote control (RC5 protocol), a Philips videorecorder remote for example. Or get a programmable remote and use code 257 (for a Philips VCR). * Several song repeat modes (song, folder, random, non-stop) LINK: http://www.lehmayr.de/e_mrmidi.htmand same thing as kit: http://www.sdmidicontroller.com/ Quote Link to comment Share on other sites More sharing options...
bill Posted November 23, 2007 Report Share Posted November 23, 2007 wow, looks good !I love the "MMC/SD card bootloader" stuff =) Quote Link to comment Share on other sites More sharing options...
Sasha Posted November 23, 2007 Author Report Share Posted November 23, 2007 When I saw this project I thought emidiately it would be great to have SD card support on MBSEQ. :) Quote Link to comment Share on other sites More sharing options...
bill Posted November 23, 2007 Report Share Posted November 23, 2007 SD card support on MBSEQWhen I saw this project I thought emidiately it would be great to have SD card support on MBSEQ. :)You mean, SD card support for MBHP ;)Maybe they are some I2C to SD adapters ? googling...

Sasha Posted November 23, 2007 Author Report Share Posted November 23, 2007 Yes, support for MBHP. Please inform us if you find some inexpensive I2C to SD adapter. Quote Link to comment Share on other sites More sharing options...
ilmenator Posted November 23, 2007 Report Share Posted November 23, 2007 I've been fiddling around with CF cards in MIOS for quite some time, but for some reason I cannot properly access them. I have tried more than one adaptor/connector, and there is quite some info including code on the net. All my work is quite undocumented, unfortunately :-[.You might want to look here, these are my sources:http://archive.chipcenter.com/circuitcellar/february01/c0201ms1.htmhttp://www.armanet.com/html/compactflash.htmlhttp://www.compuphase.com/mbr_fat.htmI did not look into FAT support, I was only going to use the card as plain memory. Best regards, ilmenator Quote Link to comment Share on other sites More sharing options...
Goblinz Posted November 27, 2007 Report Share Posted November 27, 2007 I want one.... why can't it be open source though? Quote Link to comment Share on other sites More sharing options...
seppoman Posted November 27, 2007 Report Share Posted November 27, 2007 I want one.... why can't it be open source though?Huh? It is open source, where did you get the impression that it wasn't? http://www.mikrocontroller.net/wikifiles/3/32/MrMidi2Ultimate.zipSeppoman Quote Link to comment Share on other sites More sharing options...
Goblinz Posted November 27, 2007 Report Share Posted November 27, 2007 My mistake. I ended up going straight to the kits page for some reason. Gonna have to build one when I've finished with the MB-6582 and the x0xb0x.... It may take a while! G Quote Link to comment Share on other sites More sharing options...
SLP Posted November 27, 2007 Report Share Posted November 27, 2007 Can someone of you burn an ATmega168 ? Quote Link to comment Share on other sites More sharing options...
