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) WebMar 5, 2012 · To get the level of a pin configured in input mode use GPIO_ReadInputDataBit () *. * 5.
