The console/controller communication is performed using a one-wire, half-duplex serial protocol. The data line idles high. Data is transmitted at a 250KHz baud rate, with a '1' bit represented by 1uS low, 3uS high, and a '0' bit represented by 3uS low, 1uS high. Data is transmitted MSB first. Transmissions begin at the first negative edge and continue until a stop bit is transmitted. Stop bits are only 3uS, which is important to pay attention to, especially when operating in host (i.e. Console) mode, because the controller can (and often will) respond immediately. The console transmits a stop bit as 1uS low, 2uS high, the controller transmits as 2uS low, 1uS high. In order to wire this up, we need to tie the UART's Rx and Tx pins together using a Schottky diode, as shown. One thing to be careful of when doing this is that because the Rx and Tx lines are connected together, any data sent out from the UART will also be received back, so if you are using Rx interrupts, they should be disabled during transmission, and the Rx buffer should be cleared at the end of the transmission before re-enabling them (or, if you can disable the Rx function entirely, that works too). You also need to be very careful about the timing when doing so, because stop bits are only 3uS (2 low, 1 high) which means you can't just read out the Rx buffer normally. On the PIC18F25K42, I did this by waiting for the TX buffer to be empty, indicating that the stop bit had been loaded into the Tx shift register, then waiting by manually polling the Tx pin until it went low, then high. Only then did I re-enable the UART's Rx buffer and interrupt. ![]() ![]() N64 Controller Serial Protocol Rs232. Connecting your Retro- Controllers. Please note that you do not have to use old controllers for playing old games. There are several reasonable alternatives both for controllers and games if you want to get the retro- feeling more easily. However, some people prefer the. The timing is pretty tight because the controller can respond immediately after the 1uS high period, but I was able to make it work. Data protocol. Import created QBO (Web Connect) files into.
