The Eight Pin Modes of STM32

GPIO This article is based on the HAL library The Eight States of GPIO Output Input Push-Pull Floating Multiplexed Push-Pull Pull-Up Open-Drain Pull-Down Multiplexed Open-Drain Analog Note: STM32 pins are 3.3V tolerant (3.6V is the limit), 5V tolerant (5.5V is the limit). Exceeding the pin tolerance will damage the chip. Output Both push-pull and open-drain … Read more
