The Circle Pad Pro contains many sets of calibration data. Sets with an invalid CRC checksum should be ignored. | |||
To calculate the right circle pad's position, first subtract the calibration offset from the value reported in the "Read Input" request, then multiply by the scaling factor. Dividing the result by 8 gives a value with a similar range to that of the left circle pad: -0x9C(bottom/left) - 0x9C(top/right). | |||
