1,系统函数HAL_Delay原型:voidHAL_Delay(uint32_tDelay);作用:利用滴答定时器生成的系统延迟函数参数:Delay:延迟时间,单位是ms返回值:无示例代码 2023-11-29 08:00:53 在HAL库中用定时器实现自定义延时函数delay_us() STM32程序从标准库移植到HAL库的时候,会发现HAL库中只有一个毫秒级延时函数HAL_Delay()...
STM32L152单片机驱动段码LCD屏,HAL_LCD_Init函数执行失败,卡在LCD_FLAG_RDY里面,函数返回HAL_TIMEOUT/*!< Wait Until the LCD Booster is ready */while(__HAL_LCD_GET_FLAG(hlcd, LCD_FLAG_RDY) == RESET){ if((HAL_GetTick() -...。
串口发送函数 HAL_UART_Transmit( huart1, transmit,len, timeout) 里的timeout一般设置多少比较合适?这个timeout我的理解是发送1个字节的等待超时时间,那么以9600波特率为例,发送1个字节1ms都不需要,那这个值应该设置很小的值比如10就够了,但为什么网上很多人的例程里都是设置了1000甚至更大?
