sutra Posted January 28, 2010 Report Share Posted January 28, 2010 I've been using my midibox for 3 years and i recently decided tinker with it a little, because my AIN info was coming in on separate midi channels and I wanted it to all come in on one channel. My core module has a PIC 18F452 on it so I started by using MIOS studio to upload "bootloader_v1_2b_pic18f452.hex" and followed by uploading "mios_v1_9g_pic18f452.hex". Ever since I did that, whenever I turn on my core module, all of the DOUT's switch to 1 (turning on all LED's attached to my DOUT modules). I am used to this happening when i give my core module a low voltage, causing it to go into brownout mode. I have tried repeatedly to upload my old bootstrap loader and MIOS in manual mode, but i continue to get what looks like a brownout. All of my wiring and power are the same as they have been for the last 3 years, the only thing that has changed is my successfully uploading the latest bootstrap loader and MIOS. any suggestions, anyone? - mike.

sutra Posted January 28, 2010 Author Report Share Posted January 28, 2010 i have now tried to load my old sysex file onto my new PIC chip about 100 times, and nothing seems to happen. my box isn't sending any midi events. Quote Link to comment Share on other sites More sharing options...
