STM32 implements IAP and APP file merging

;The following is the configuration file of the merged program. Please note that the offset address of APP is 0x2000... For all folders, please refer to my resource post. ; Only for FLASH less than 64K, those requiring larger capacity will be launched later. ;-------------------------------------------------------

Error in burning large capacity chip of stm32

There is always an error when burning stm32f103vet6. The amount of generated code is not very large relative to the chip capacity, which is 512K flash and 64K RAM. The generated code is about 32K The configuration of MDK is full erase chip, program → verify → reset and run It will stop responding at a certain t

stm32 assert_param function

When we learn STM32, the function assert_param is very likely to appear. If you search online, you will find that the assertion mechanism is generally explained online and is used during the program development and debugging stage. Next, I will talk about my views on these applications. When learning something, you sh

STM32 key input, required C language review, clock system block diagram

first part: STM32 key input is my second small example of input on the STM32 platform. The idea is to first query the hardware diagram to see whether the key is low-level effective or high-level effective. According to my development environment, I know that three of the four keys are low-level effective and one is hi

stm32 timer 3 generates a specified number of pulses

1. Scenario description: Use PB5 to generate a certain number of pulse signals. PB5 is the second channel of timer 3. 2. Generate PWM code: void Timer3_Configuration(void ) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_OCInitTypeDef TIM_OCInitStructure; TIM_DeInit(TIM3); // ÆµÂÊ30K //Õ¼¿Õ±È50% //

STM32 external crystal oscillator 8M changed to 25M

Note: Modify F4 to stm32f4xx.h/system_stm32f4xx.c, modify F3 to stm32f10x.h/system_stm32f10x.c One of the modifications: HSE_VALUE in stm32f4xx.h, the system uses an external 8M crystal oscillator by default, so #define HSE_VALUE ((uint32_t)8000000), now change it to #define HSE_VALUE ((uint32_t)25000000) Modifi
