The board ESP32-LyraTD-SYNA is not defined in the audio board and the audio codec of this board is CX20721, but in the components\audio_hal\driver directory of the SDK, there are only drivers for es83 series and other chips. Does this evaluation board have some example code working of...
3.进入主题lv_example_get_started_1 4.为何选这个例子入门 5.esp32 跑lv_example_get_started_1(附源码) 刚接触lvgl,看了一些教程,感觉还是无法下手。我还是先跑跑example。这两篇介绍如何使用visual studio 2019仿真lvgl的文章不错: 1.作者:Mculover666,《 ...
Smart_Config的初始化函数,回调函数,任务函数都直接复制Smart_configDemo中的即可,但是得注意 其中的任务smartconfig_example_task配网结束后需要删除,节约空间,如下图: 在这里插入图片描述 1.2 周期上报数据(Timer) 周期上报数据使用硬件定时器方式,使能一个 自动重装载的定时器,在定时器中断函数中改变状态位,提醒需要...

ESP32应用程序可以在运行时通过Wi-Fi或以太网从特定的服务器下载新镜像,然后将其闪存到某些分区中,从而进行升级。在ESP-IDF中本文采用native_ota_example进行空中(OTA)升级: 为了简单起见,OTA示例通过在menuconfig中启用CONFIG_PARTITION_TABLE_TWO_OTA选项来选择预定义的分区表,该选项支持三个应用程序分区:工厂分区、...
