Detailed Explanation of GPIO Operations for 32-bit Microcontrollers
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
Can Microcontrollers Truly Execute Multiple Tasks Simultaneously?
Many students ask me: Why does my LED light blink while the serial port data reception gets stuck? I want to read data from two sensors simultaneously, why is it that one of them always reads incorrectly? Why can’t my program control the motor while sending data? The most classic question is: why can’t I … Read more
