Hi,
Using the ATU-10 v1.2 board and got to the point where both MCU's are apparently programmed.
1. Programmed the 1454 with the MPLAB IDE
2. Plugged in the board, it came up as a disk on my PC, and dragged and dropped the hex file for the 18877 to that disk. I got the copy progress bar, and afterwards I checked the size vs the original and they matched. Unplugged the board, and plugged it in and it mounted as a disk, and only the htm file was there (I assume this is normal...?)
Unplugged the board again, plugged in the OLED (yes i confirmed polarity) and nothing... No backlight, no nothing.?
Swapped OLED's and cables, still nothing.
Confirmed continuity between the 18877 and the OLED headers, and the sda, sdl, and Vcc checked. Plugged the board in without the oled connected, and there was ~4.3V on vcc..
Could this be an I2C address issue? Or perhaps the 18877 is dead?? Suggestions on where to go from here?
Thanks
