Funny that I found this post by coincidence, with basically the same question I asked a few months ago, though it was on github. https://github.com/espressif/esp-idf/issues/5517 It's also a bit ironic, given that people prefer to post there than here since this forum seems mostly dead. Like OP and I...

Do you have multiple, like one for release and one for development? When updating IDF, which usually deprecates a bunch of configs, what do you do? Nothing? Manually audit the text file? Audit through menuconfig? Remake the entire file? Are there other options? Except for the (painstaking) option o...

How to properly do it? Like many parts of IDF, the documentation is lacking, and the only thing I know is that I have to call `esp_netif_set_ip_info` with the DHCP client not running. Is there no way to kickstart the netif library with this information loaded already, or do I really have to start it...

I'll risk a guess and say it's something related to the OS scheduler plus the fact that `spi_device_queue_trans`, as implied by the name, queues interrupt transactions providing non-blocking transactions, at the expense of time to service the interrupt when the transactions are done. Also, your pre ...

By minimum I mean enough to run 'menucon...

Awesome. A couple more questions... https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/timer.html#interrupts When handling an interrupt within an interrupt serivce routine (ISR) I don't really get the wording here. Interrupts are handled inside ISRs, right? Since that's ...

Oh well, I just posted another closely related question on the forums and I can't find it due to it being submitted to approval, because I thought this one had not been posted and I didn't see any notification until after I did it. I would like the discussion to continue on the other thread, as I go...

1. What is the point of a prescaler anyway? From what I understand, it scales down the clock count, which basically reduces the resolution of the counter. 2. Why would that be good or intended? There must be a very good reason why hardware makers would put that in a CPU, and why is that? Moving on t...

https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/timer.html#introduction The ESP32 chip contains two hardware timer groups. Each group has two general-purpose hardware timers. They are all 64-bit generic timers based on 16-bit prescalers and 64-bit up / down counters ...
