esp32s2关于同时使用wifi和lvgl出错重启是什么原因

Postby 20岁开始秃头 » Sat Mar 05, 2022 3:42 am

我尝试在用lvgl做一组wifi扫描连接界面，但加入wifi扫描后，esp32s2就不断重启，使用的版本是release4.4，vscode c开发。具体我也去查过，也有人遇到这个问题，他用的是arduino，说是lvgl调用的系统计时和freertos任务调用wifi时起了冲突，但说的很笼统，不太熟悉freertos，头秃搞不明白，有什么办法能解决吗。代码和出错信息如下：

Re: esp32s2关于同时使用wifi和lvgl出错重启是什么原因

试试把tick task放到 esp_timer 中,而不是放到 freertos tick hook中,可以参考这个example对lvgl的移植

感谢，我之前想到了这个，尝试将tick_task放到esp_timer_handle中，可问题仍然未能解决，代码部分如下：
Code: [Select all] [Expand/Collapse]

  2. {

你这很有可能是多线程引起的问题,操作UI部分,增加互斥看看,我也在用lvgl 不过我是S3芯片

感谢，我尝试一下，不过在之前我添加了关键变量的互斥锁，也没起效果

我也遇到这个问题了，我不是用的s2，反正不用wifi都正常。
然后我用的spi驱动st7789，我分析代码，感觉是死锁了，一边一直在判断是否在flushing，而这个始终无法被置位，看样子驱动部分得自己写才行了
