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!

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

Thanks bro. That's ok. At least I know that the code is compilable and the problem is inside my PC. I'll definitely try to make it. Cheers.

Hi Findbuddha. Thanks for the hint. but it didn't solve the problem. I even tried compiling it in Notepad++ but the result was exactly the same. Would you please compile the code I have attached and see if it makes the HEX file in your PC? If you succeeded please send me a copy of HEX file. Regards Ciro

Hi Peter Thank you for your reply. I have installed the MSYS. It responds when I check its version with [Make -version] command. I have really no idea what is wrong!

Hi Guys It's a couple of weeks I'm trying to compile the USB PIC project code without any success. I have already installed the toolchains and set the Path in windows XP exactly according to the instructions in WIKI, but I still receive this error message and no HEX output! ---------------------------------------- rm -rf _output/* make: /bin/sh: command not found make: ***[Clean] Error 127 --------------------------------------- Is there anyone one who can compile this code for me and tell me what is wrong with it? What is missing in my PC; or what should I do that I currently not doing? Thank you in advance. Ciro src.zip

Hi fellows can anyone tell what is the best IDE for compiling the code I have attached to this message? This is the code I have downloaded from midibox website. I've already tried MPlab IDE and Mpasm and Mplinker but seems that they are not proper tool suits for this project. So far I know that I have to use SDCC and GPUTILS together because this project has a USB descriptor written in C language "usbdsc.c". I have downloaded the toolchains , Notepad++ and Piklab IDEs but I don't know which IDE should I use and HOW??!!! To be honest, I could not figure it out after 7 days of struggling!!!! I appreciate any help. Regards Ciro Code.zip

Thanks bro.

Thanks Thorsten for your help. can you tell where can I download the MIOS8 toolchain?

Hi Folks. I can't make the source code compiled. Mplinker gives an error.
