1. 什么是 esp_error_check? esp_error_check 是ESP-IDF(Espressif IoT Development Framework)中的一个宏,用于在 ESP32 开发中对 API 调用返回的错误代码进行检查。如果 API 调用失败(即返回的错误代码不是 ESP_OK),则会触发一个断言失败,导致程序崩溃并打印出详细的错误信息,包括出错的文件名、行号和具体的...

ESP_ERROR_CHECK(i2c_master_cmd_begin(I2C_MASTER_NUM, handle_i2c, pdMS_TO_TICKS(I2C_TIMEOUT_MS))); Since there is no I2C device attached, the assert here will fail, and abort will be called. I'd love for my device to be able to handle this a little more gracefully, and simply pr...
