currently I have connected 8 LEDs on these GPIO pins and easily i can access them bit by bit using WRITE_PIN and READ_PIN using gpio-mmap.h file, These LEDs are glowing according to given values,. But I want to access all pin at once as a GPIO P...
gpio_evt_queue = xQueueCreate(1, sizeof(uint32_t)); // 创建gpio队列 bool status = 0; // 记录goio的状态 // 下面是按钮逻辑处理 while (xQueueReceive(gpio_evt_queue, &gpio_num, portMAX_DELAY)) { bool key_level = gpio_get_level(gpio_num); vTaskDelay(pdMS_TO_TICKS(10)); // ...

The while loop below can be replaced with user application code. */ while(1U) { pin_status = XMC_GPIO_GetInput(XMC_GPIO_PORT1, 15); if(pin_status == 1) { XMC_GPIO_SetOutputHigh(XMC_GPIO_PORT1, 0); } } } 已解决! 转到解答。Like 回复 订阅 60 次查看 0 1 条回复 ...
if (bdata->gpiod) gpio_keys_handle_button(bdata); } gpio_keys_polled_queue_work(bdev); }有驱动代码可知,gpio_keys_polled_poll被放在工作队列中处理,gpio_keys_polled_poll中一直在调用gpio_keys_handle_button函数,我们主要分析这个函数:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 ...
GPIO0->GND RST->GND烧录前按下上电 然后就是串口选好和开发板选好 准备烧录 还没传输数据前 要按住rst上电放开手即可。gpio0一定要接入gnd 随后用的以前有个小E开发板来接的 最终代码(需要更具自己的修改): 1/*2* 天猫精灵控制3* 2020-05-124* QQ交流群:8242732315* 官网https://bemfa.com6*/7#in...
unsigned char GPIO_IF_Get(unsigned char ucPin,unsigned int uiGPIOPort,unsigned char ucGPIOPin) ucPin和ucGPIOPin有什么区别? //! \param ucPins is the bit-packed representation of the pin(s). 不知道你这个函数哪个文件夹的,我没找到,你可以找到这个函数的出处,就是 头文件对应的.c里面...
