用了blink案例，光有打印，没有灯闪
Posted: Mon May 24, 2021 5:02 pm
用的是esp/esp-idf/examples/get-started/blink的案例，烧录进ESP32-C3-DevKitM-1的开发板中。
打开监视器看，只有"Turning off the LED"/ "Turning on the LED"的交替打印，但是灯没有闪。
编译指令如下：
475 get_idf
476 idf.py set-target esp32c3
477 idf.py menuconfig
(Top) → Component config → ESP32C3-Specific → Minimum Supported ESP32-C3 Revision--->Rev 2
478 idf.py build
479 idf.py -p /dev/ttyUSB0 flash
打开监视器看，只有"Turning off the LED"/ "Turning on the LED"的交替打印，但是灯没有闪。

- vTaskDelay(1000 / portTICK_PERIOD_MS);
- }
