Khron_X Posted July 30, 2009 Report Share Posted July 30, 2009 Greetings everyone...I'm a long-time audio DIY-er, but i've only quite recently started dabbling with/in the digital (hardware) world.Now, for my big question: is there anyway to directly link 2 MBHP_IIC_MIDI modules to an MBHP_USB_PIC? (or to something like THIS )I'm aware that buying an interface would be far simpler, but... there's no DIY satisfaction in that :PMany thanks in advance,Chris Quote Link to comment Share on other sites More sharing options...
Eduy2kk Posted July 30, 2009 Report Share Posted July 30, 2009 Hi, read this: http://www.ucapps.de/mbhp_usb_pic.htmlI use a PIC 18F2550 with TK's soft USB-PIC + 1 module IIC with the PIC 16F88 and it works well or also a PIC 18F4550 + 4 IIC, but only 2550 or 4550 the midi in does not work well for the famous BUG of the UART.I run this hard in Windows XP OS only.Eduardo Quote Link to comment Share on other sites More sharing options...
Khron_X Posted July 30, 2009 Author Report Share Posted July 30, 2009 Oops :-[ I guess i rushed a bit, and didn't read that page thoroughly enough. (And i thought the module connected to those 4 IIC interfaces was a Core module...)So Eduy2kk, which configuration WORKS? USB-PIC + 1 IIC, or 4 IIC? And which PIC is in the interface, 2550 or 4550?(I understand, you're not a native english speaker, but your reply is a bit confusing :) ) Quote Link to comment Share on other sites More sharing options...
Eduy2kk Posted July 30, 2009 Report Share Posted July 30, 2009 Lamentably my language is not English. I speaks Spanish, excuse you for my bad english.In the link of the previous post explains in english well like to construct and programme it.The module USB-PIC is not a module with the MIOS but with a specially designed soft. If you think to use only a one port of midi in / out you can use 2550, if you think to use two or more midi in / out must use 4550.In the post that I you put later you have all the information to be employed at this, http://www.ucapps.de/mbhp_usb_pic.htmlhttp://www.ucapps.de/mbhp_iic_midi.htmlAlso you can see 2 converters and the GM5 is it the best alternative and works well on OS of PC and Machttp://www.ucapps.de/mbhp_usb.htmlhttp://www.ucapps.de/mbhp_usb_gm5.htmlEduardo Quote Link to comment Share on other sites More sharing options...
Khron_X Posted July 31, 2009 Author Report Share Posted July 31, 2009 I didn't mean any criticism or offense about the language, just that i didn't understand 100% what you meant, that's all :) (I prefer to ask for clarification, than assume the wrong things :P )Hmm... Is there any special reason why there's the "one channel restriction" for the 2550? I carefully read the whole USB-PIC page yesterday, and (i think) the only reason why the 4550 is recommended is that TK only got a post-12-2007 4550 with the EUSART bug fixed, but not a "fresh" 2550.But if there's a technical reason, i'd be curious about it. From what i could see in the datasheet, the big difference is 3 extra i/o ports (10 vs 13), and some other minor different features, which might not be used here.The GM5 isn't really an option. I can't know WHEN the minimum order quantity will be met, plus i can put together the pic-based version quite easily, and 100% diy :) Quote Link to comment Share on other sites More sharing options...
