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
1. void GPIO_DeInit(GPIO_TypeDef* GPIOx); First, let’s take a look at this function. We can see that the parameter of this function is a GPIO group parameter (GPIOB, GPIOC, GPIOA, etc.),Now, let’s enter the definition of this function in the standard peripheral library. void GPIO_DeInit(GPIO_TypeDef* GPIOx){ /* Check the parameters */ assert_param(IS_GPIO_ALL_PERIPH(GPIOx)); if (GPIOx == GPIOA) … Read more
Introduction Have you ever encountered difficulties in Linux embedded development when trying to directly manipulate hardware interfaces such as GPIO, LED, PWM, SPI, I2C, MMIO, Serial, etc., only to find that the native APIs are complex, cumbersome, and hard to maintain? Or do you find yourself writing a lot of low-level code every time, making … Read more
Hello everyone, I am a newly hired embedded engineer. Like many friends who are just starting out, I feel both excited and a bit anxious in the vast ocean of technology: how can I transform the theories from books into the ability to solve real problems? My answer is – to get hands-on with a … Read more
