The brown-out detector works to give a quick reading on why an ESP32 malfunctions (without it, you may get weird behaviour from the CPU that e.g. may look like a spurious software issue; the BOD makes it immediately clear that the voltage level is out of spec), but it doesn't replace an external ...

I am using ESP32S3 WROOM1 N16R8 on my own PCB. Due to my faulty USB hub, my board may receive brownout reset randomly- and this is intended. However, I noticed that after a few sequential Brownout in tens of seconds, it no longer reboots. I checked the reset pin, power supply, etc. and they are all ...

最后自己找到的问题之所在，倒腾了好久，发现wifi发射的Power值超出了要求的设定值，获取到默认值是100，而要求设定tx_power是在84以内。

最后通过esp_wifi_set_max_tx_power函数设定20，即5dBm的功率为发送频率，wifi就正常连接和通信，不知道这个是不是bug？

Welp, I could confirm that the correct combination to make PCNT and gpio interrupt work simultaneously is: PCNT setup -> gpio config -> gpio interrupt handler

I have tried gpio_config > gpio_add_handler > pcnt setup as well as gpio_config > pcnt setup > gpio_add_handler. In either case,only pcnt works. the interrupt handler won't be called. Without pcnt the interrupt worked

Hi, I am implementing a pulse counter for an encoder. I would also like to capture the edge in ISR and perform some action. However, when both PCNT and interrupt using `gpio_isr_handler_add`, the interrupt handler no longer gets called. I assume this was because the signal was routed to PCNT ...

Hello all,

I designed a prodcut with ESP32S3NxR2 and the firmware was set to using quad PSRAM lines. However, due to stock issue a recent batch was assembled with ESP32S3NxR8. While I was told the R8 version is compatible with R2 in quad mode, it turned out to be not true and I was getting

I succeed implementing the asynchronous response using the following code
Note the commented code, where I assumed that httpd_queue_work is used to delegate the http communication to the http server thread. However, without using httpd_queue_work it works just fine. This makes me wonder more ...

Hi, I am looking at the http server component and found this function: httpd_queue_work. After tracing the source code, I found that It merely ask the http server thread to invoke the work callback immediately. The callback is not called in a standalone thread. I wonder what is the purpose of using ...
