Ciro Posted October 19, 2012 Report Posted October 19, 2012 Hello everyone Does anyone know if it's possible to change the MBHP's source code to work with PIC18F14K50? Pic18f2550 and 18f14K50 are not pin compatible but I believe that it's possible to adapt the source code for 18f14k50. This chip is two times cheaper than 2550. I have attached the source code to this post.mbhp_usb_pic_v1_1.zip

Shuriken Posted October 20, 2012 Report Posted October 20, 2012 (edited) I assume you mean the MBHP_USB_PIC firmware? You know that it does not work reliable? Edited October 20, 2012 by Shuriken
Ciro Posted October 21, 2012 Author Report Posted October 21, 2012 (edited) Yes I do mean the MBHP USB PIC firmware.of course it is reliable. I personally tested that with different MIDI gears; using different USB expansion boards and hubs, and it works just great. Like a professional M-Audio interface. Pic18f14k50 is way cheaper and has a smaller package respect to 18f2550. it makes the whole thing to be smaller and more economic! I'm already working on this but I definitely need others help. Ciao!

TK has put quite a lengthy explanation on the project page. The GM5 was the prefered solution (until the ARM boards arrived). But i wish you good luck on your endeavor.

TK. Posted October 21, 2012 Report Posted October 21, 2012 Unfortunately I won't have the time to port the firmware for other PICs; and I wouldn't be able to try out changes by myself... Best Regards, Thorsten.
