Hmm, i wonder : what do you plan to do with servos ? (i just received my i2c servo driver... stay tuned ;)

:) merci je suis à république (75003)

Bonjour messieurs dames, Je recherche qquelqu'un sur paris pour me programmer un PIC16F872 ! (c'est une cacahuète a 28 pattes) à votre bon coeur ;D Merci beaucoup !!!

SD card support on MBSEQ You mean, SD card support for MBHP ;) Maybe they are some I2C to SD adapters ? googling...

wow, looks good ! I love the "MMC/SD card bootloader" stuff =)

No problem for the 9v battery (hehe, i love portable devices too), Then, do not use a screen, because it will suck most af your batterie juice... But, i suggest that you order a lcd screen to debug, and when you app is ready, just disconect the screen ;)

Check this : http://www.hobbyengineering.com/H1591.html http://www.crownhill.co.uk/product.php?prod=1267 (looks very interesting, i ordered one!) I plan to try it, but maybe only after my mbhp stepper motor driver :)

ouch, but they look pretty expensive :-\ (5,73 € on farnell) http://fr.farnell.com/jsp/search/browse.jsp?N=0&Ntk=gensearch_004&Ntt=ds1267&Ntx=&_requestid=37183

hmmm, those DS1267 looks very interesting It must be possible to do some pwm with this and a ne555, then drive servomotors with mios... So, no one tried yet ? I'm going to buy one or two of those chips ::)

Ok, next time, count me in ::)

Hey, i can help you with the code as well (i have a similar project, search in the forum for "xylophone" ;) then, maybe you can help me finding suitable solenoids ? ::)

if someone is interested, let me know, so i do a user project page for this :)

Concrètement, ça sert exactement a faire ce que tu cherche. Tu as plusieurs entrées, plusieurs sorties, le routeur te permet de gerer des liaisons virtuelles entre les entrées et les sorties, a ton gré. (melanger les signaux par exemple) C'est un genre de "patch", midi.

Salut, j'ai jamais essayé de faire un midi merger, mais bon, ton montage me parait assez hardcore :-\ Est ce que ce projet ne serait pas plus adapté ? ;) http://www.ucapps.de/midi_router.html

Thank you all for the tips ! :) yes, i've seen them, unfortunately, they dont have those cheap and small ones i need, those ones are good to lock a car door or that kind of stuff ;) (they are too big) yep, i know that's a bit of work there, but i did that in the past. i know i need ULN2003A transistors network (or equivalent) to boost the douts, before attacking some relays, self protecteds by "free wheel" diodes preventing the "impedance rupture". In fact, I have the "power" board ready yet ;) Atm, i'm just in a quest of the "perfect solenoid" ^^ I cant wait to send my MBXylophone video ;D

Hello, I woud like to (try to) build a midified percussion organ (xylophone like), so, i need some kind of solenoids to drive the sticks. I think i'm capable of doing it (seems pretty simple) but, i have no idea where to get those "percussion engines" Any tips for this ? Thanks :)

Then i take 2 ;D (i need one for my MBHP Clock/Cron Project hehe)

I had one like this in my hands, (a friend gived it to me) but i never found any info on this (like where to get softwares to control it etc) so i trashed it :'( Stupid me, i could'nt imagine it sounded that good !

now it works ;D more details soon !

Thank you Thorsten, your example help me a lot (to understand how it's supposed to work), today i found this http://www.techdesign.be/projects/routines/ds1307_void_a.htm This is basically what you wrote yesterday (minus the first "STOP") I also found some code supposed to work : http://jambonbill.free.fr/midibox-kb/MBHP-CLOCK/main.c.txt http://jambonbill.free.fr/midibox-kb/MBHP-CLOCK/ds1307.c.txt I will continue to experiment this evening ;)

I'm sorry to ask again for help, and to look like an asshole, but i have one more question that maybe some of you could answer. The DS1307 doc (http://www.rev-ed.co.uk/docs/DS1307.pdf) say : So, i'm only interested on the "real time clock registers" at the moment, so, all i need to get is the 8 first bytes after this MIOS_IIC_Start(); // start IIC MIOS_IIC_ByteSend(slave); // send device address is that right ?

I know slave adress should be 0xD1 (1101000+1) (the 1 is for "read" mode) I did enable clock stretching with MIOS_IIC_CtrlSet(0x01); but my received bytes are still random... :-\

Dear forum, I bought a board like this one to experiment IIC : http://www.futurlec.com/Mini_DS1307.shtml http://www.rev-ed.co.uk/docs/DS1307.pdf so i connected the board to the core without problem, and initialised the IIC like this : void Init(void) __wparam { MIOS_IIC_Stop(); // init IIC interface } then, looking at the speakjet code i did this : unsigned char IIC_TransmitStart(unsigned char _slave) __wparam { unsigned char retry_ctr; // start IIC access MIOS_IIC_Start(); // send address retry_ctr = 0; while( !MIOS_IIC_ByteSend( _slave ) ) { // slave has sent a NAK - retry 255 times MIOS_IIC_Stop(); if( ++retry_ctr == 255 ) return 0; MIOS_IIC_Start(); } return 1; } and this : (slave value is 0xD0) void DISPLAY_Init(void) __wparam { MIOS_LCD_Clear(); if(!IIC_TransmitStart(slave) ){ MIOS_LCD_CursorSet(0x00); MIOS_LCD_PrintCString("IIC Transmit error !"); }else{ MIOS_LCD_CursorSet(0x00); MIOS_LCD_PrintCString("IIC Transmit OK"); } } at this point, everything seems ok, i have "IIC Transmit OK" :) then, i try to read some values so i did : void GET_TIME(void){ MIOS_IIC_Start(); // start IIC MIOS_IIC_ByteSend(slave); // send device address - // set bit #0 to notify a read!!! // don't continue if IIC device not available if( MIOS_BOX_STAT.BS_AVAILABLE){ b0 = MIOS_IIC_ByteReceive(); MIOS_IIC_AckSend(); // send acknowledge b1 = MIOS_IIC_ByteReceive(); } MIOS_IIC_NakSend(); // send disacknowledge!!! MIOS_IIC_Stop(); // stop IIC MIOS_LCD_CursorSet(0x40); MIOS_LCD_PrintHex2(b0); MIOS_LCD_PrintCString(":"); MIOS_LCD_PrintHex2(b1); } but all i read, whenever i call this function is just some random values, instead of seconds :-\ maybe this project is a little too complicated for me, to be honest, i dont know exactly how it's supposed to work, but i guess i'm must not be that far from the goal, so i hope some people here can explain me what i did wrong, or did not :) thanks for reading !

I'm interested ! Count me in :) (i'm in france)

Did you try the MMC-64 ? it's great ! ;D
