我们进入该窗口后,点击右边箭头所指的加号,在Basic Settings的Port中下拉选择连接相应的端口,每个人端口号不一样,具体的端口号可以在电脑的设备管理器中看到,本机为COM3。 图2.5.3 设置UART 由于我们在硬件中设置UART的波特率为默认值115200,所以此处无需再设置,其它的保持默认即可,点击“OK”按钮。 6-2 下载程序...

可以看到复用函数hi_io_set_func、hi_io_set_pull函数并未进一步封装到//base/iot_hardware/peripheral/interfaces/kits/iot_gpio.h中,这个在OpenHarmony2.x中也未做,写起来不太方便,希望后续统一,比如设定为IoTGpioSetFunc()、IoTGpioSetPull()函数,当然也可以自己封装。
if ((portHwiCreatedBitMask & gpioPortIntBitMask) == 0U) tell me only one port can register interrupt.The Gpio4_15 had registered,the GPIO4_14 and GPIO4_57 can't register and route the irq. Now i want to use three interrupt sources and three factions of callback, ple...

void GPIOIntEnable ( uint32_t ui32Port, uint32_t ui32IntFlags ) Enables the specified GPIO interrupts. Parameters ui32Port is the base address of the GPIO port. ui32IntFlags is the bit mask of the interrupt sources to enable. This function enables the indicated GPIO interrupt sources....
