I just had to change in the firmwareprog_uchar firmware_data PROGMEM =To:const char firmware_data PROGMEM =
and a picture of how I cable the ADNS with arduino
the wire are all connected correctly to the board asI wrote on the image
I got another question now, do you think I can plug 2 ADNS 9800 to one arduino UNo?
Features: Works with Arduino SPI library
