WebOct 11, 2024 · The next time you read that port back to change another pin, the input for the pin reads 0. You modify the value for the pin you intended to change. You write the value back. Now not only has the intended pin changed state, but so has the pulled-down output. The other component stops pulling the pin down. But your micro keeps outputting 0 ... WebMar 14, 2013 · This circuit works such that if you set a pin to 0, the output will be pulled to ground and can only be read as 0 because externally you can't pull it high. If you want to allow both levels to be input, you have to set the pin to 1. In this case you can: leave output floating if you have internal pullups (reads as 1) pull output to Vcc (reads as 1)
