Received feedback from many readers: “Clearly following the tutorial, but the STM32 board’s LED won’t light up?” This phenomenon hides hardware differences in embedded development that are easily overlooked, the connection method of the onboard LED and GPIO pins, is the most common “pitfall” for beginners transitioning from Arduino to STM32. Every line of code … Read more
Why do we need pull-up resistors in I2C? Because it uses open-drain output. Why is it open-drain output? The I2C protocol supports multiple master devices and multiple slave devices on a single bus. If push-pull output is used instead of open-drain output, it could lead to short circuits between master devices. Therefore, the bus generally … Read more
In embedded system design, we often need to use the General Purpose Input/Output (GPIO) pins of microcontrollers (MCUs) to drive peripheral devices such as LEDs and relays. I still remember that my first code in college was to control the blinking of an LED using the 8051 microcontroller. I wonder if the current university courses … Read more
32 Single Chip Microcontroller I O When it comes to the IO of the 32-bit microcontroller, taking the F1 series as an example, we first need to mention: 1 initialization function: void GPIO_Init(GPIO_TypeDef* GPIOx, GPIO_InitTypeDef* GPIO_InitStruct); 2 functions to read input levels: uint8_t GPIO_ReadInputDataBit(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin); uint16_t GPIO_ReadInputData(GPIO_TypeDef* GPIOx); 2 functions to read output … Read more
