LED灯的闪烁在主函数while循环中直接使用延时控制:HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);HAL_Delay(1000);测试正常,这个延时1S钟靠肉眼识别,如果有误差其实也看不出来,影响delay应该是和系统时钟有关,后续再确定是否正常; 相关知识点: 试题来源: 解析 检查系统时钟配置是否正确,使用示波器测量LED引脚波形确

im triying to do that a withe led strip (12v) blink like a binary counter, its 6 seccion of these strip, so i use the my_first_fpga project for altera and change the pin assigment from the led pins to the gpio port pins i need, but dosent work. i tried to sea...
