IOIO Users,
I want to asking about my SPI code, when program is running, the led on
board is on, and the graphic is running( command: *redraw();* ), but
seems something wrong about my data SPI ( array: *response_ReadData[3],
**response_ReadData[4],
**response_ReadData[5]* on *public void loop()* ) because that array is
constant value, on my design must be not constant value. Beside that the SS
pin is high when i check using multimeter, please check this code:
