[STM8S003] GPIO multiplexing problem TIM2_CH3 uses PD2 pin output

Recently, I made a product using the STM8S003F3 chip. The product requires the use of TIM2 to output a PWM waveform on the PD2 pin. Installed the STM8-specific version of IAR, downloaded the STM8 library file, created a new project, and started writing functions. Since I had no experience with STM, I consulted a l

stm32 compile error..........ER_IROM1: File exists problem

The chip model is STM32F103CB (128K). A constant array is defined at address 801F000 in the project. When compiling, an error occurs: ER_IROM1: File exists ........ It is found that the chip model was previously set to STM32F103C8 (64K) for the convenience of the program. The program space size is different, so an er

Comparison of interrupt systems among C51, STM32 and S3C2440

/* Name: Comparison of interrupt systems of C51, STM32 and S3C2440 Description: As for the interrupt systems of these three chips, as far as I know now, I would say: almost the same. Here, almost the same means that the interrupts are essentially the same. First, the interrupt source applies (such as triggering an e

STM32 reset and system clock

First of all, we should understand that reset is a very important part. The quality of the reset part design is related to the stability of the entire system. Generally speaking, STM32F10 series chips have system reset, power reset and backup area reset. Here we will explain the basic knowledge points of the three res

STM32 NVIC Learning

Read NVIC: System Interrupt Management. My understanding is that it manages the interrupts within the system and is responsible for turning on and off interrupts. Basic Application 1, the initialization function of the interrupt, including setting the interrupt vector table location and turning on the required inter
