WebOct 28, 2015 · To enable the pull-up or pull-down resistor on a pin, you can use the GPIO_InitStruct.Pull. Set it to GPIO_PULLUP or GPIO_PULLDOWN respectively. Which one … WebSetting PxSEL to 0 selects GPIO mode. PxDIR – If the pin is set to operate as GPIO, the bits in this register select whether a pin is a high impedance input (0) or an output (1). PxOUT – If the pin is set to operate as GPIO Output, this pin selects High (1) or Low (0) output.
