硬件原理图程序：int main(void){ //Flash_EnableReadProtection();//RDP设置 使能读保护 HAL_Init(); //MX_IWDG_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_I2C1_Init(); MX_ADC1_Init(); MX_TIM2_Init(); MX_NVIC_Ini

STM32G031 ADC采集数值为0问题

求助各位大佬，请问复位是什么情况？int main(void){ HAL_Init(); SystemClock_Config(); while(1) { static uint8_t uart_init_flag = 0; if(uart_init_flag == 0) { if(get_sys_time_us() > 2000) {

STM32G0系列 程序设置读保护和取消2.读保护函数int main(void){Flash_EnableReadProtection();While（1）{}}void Flash_EnableReadProtection(void){ FLASH_OBProgramInitTypeDef OBInit; __HAL_FLASH_PREFETCH_BUFFER_DISABLE(); HAL_FLASHEx_OBGetConfig(&a.

IntroductionThe Futaba S-BUS protocol is a serial protocol to control servos. Up to 16 proportional and two digital channels are available. The protocol is derived from the very known RS232 protocol used everywhere. The signal must be first inverted...

开发环境：IAR for STM8芯片：STM8S105K4内容：在程序中写了一个关于GPIOC下降沿中断内容如下//按键引脚与寄存器定义#define KEY1_PIN (0x01 << 3)#define KEY1_DDR (GPIOC->DDR)#define KEY1_CR1 ...

在擦除扇区和写入扇区时报FLASH_ERROR_PROGRAM错误。可能原因：flash没有初始化。在操作前初始化即可。void drv_flash_Init(void){ FLASH_Unlock(); FLASH_ClearFlag(FLASH_FLAG_EOP | FLASH_FLAG_PGERR | FLASH_FLAG_WRPRTERR);}...

开发环境：IAR for STM8芯片：STM8S105K4内容：应为之前用STM8S105K4开发过CC1101RF模块用的是io模拟spi。因此开发LoRa也用了io模拟spi结果LoRa初始化没问题，但是一发包/收包就会死。io模拟spi如下void LORA_delay(unsigned int n){ unsigned int m=0; for...
