ArduCAM-Mini-5MP-Plus Hardware Application Note The first bit[7] of the command phase is read/write byte, ‘0’ is for read and ‘1’ is for write, and the bit[6:0] is the address to be read or write in the data phase. ArduChip register table see Table 1. 6 External Trigger External hardware trigger input can be used to start a capture manually, software part only needs to polling the "capture done" status bit before reading the image data.
