确认led_pin、led_gpio_port和dht11_pin这些宏的完整和正确的定义: #define led_pin gpio_pin_13:这个宏定义看起来是正确的,它定义了一个名为led_pin的宏,其值为gpio_pin_13。这通常表示LED连接到GPIO端口的第13号引脚。但是,需要确保gpio_pin_13在当前编程环境中是有效的。在STM32等微控制器中,通常会...
Data would be strobed in using other GPIO pins for "E" and "R/S" - easy stuff. Moving this to LPC844 MCU and MCUXpresso - I have got the general idea of the new API, but I cannot seem to figure our how to implement this same "4-pin" port or group for this same nibble-size...

在调用 GPIOx_ReadPortPin()时,返回复位值,如GPIOA_ReadPortPin(GPIO_Pin_10)的时候直接返回了10,查了一下寄存器R32_PA_PIN的低16位在复位情况下会返回键位原值,有的时候调用GPIOx_ReadPortPin()正常,有的时候异常,是怎么回事; 在官方例程和库中没有提供外部中断的双边沿触发模式,我写代码的时候先设置上升...
