Also known as CTR-009, it sends the commands to the console through the IR interface on the back of the console.

Pictures of its contents.

Usage Instructions

IR Protocol

Communications with this device is done via the ir:USER service, which uses obfuscation implemented in software. The bitrate-value passed to IRUSER is 0x04, hence the actual bps is 96000.

The application sends requests via IRUSER:SendIrnop and receives response from Circle Pad Pro via IRUSER:ReceiveIrnop (or read data from the shared memory). The request and response data structures below are payloads in packets.

Read Input

Request (3 bytes):

offset Size Description
0x0 0x1 Request ID? Fixed value 1
0x1 0x1 Unknown
0x2 0x1 Unknown

Response (6 bytes):

offset Size Description
0x0 0x1 Response ID? Fixed value 0x11
0x1 0x3 Right circle pad position.

This three bytes are two little-endian 12-bit fields. The first one is for x-axis and the second one is for y-axis.

0x4 0x1 bit[0:4] battery level?

bit[5] ZL button

bit[6] ZR button

bit[7] R button

Note that for the three button fields, the bit is set when the button is NOT pressed.

0x5 0x1 Unknown

Read Calibration Data?

Request (6 bytes):

offset Size Description
0x0 0x1 Request ID? Fixed value 2
0x1 0x1 Unknown
0x2 0x2 Unknown.
0x4 0x2 Data size

Response (5 bytes + requested size)

offset Size Description
0x0 0x1 Response ID? Fixed value 0x11
0x1 0x2 Unknown. Same as request+0x2
0x2 0x2 Data size
0x4 data size calibration data?
