We would like to run ESP32 modules on a 2.4-2.7V supply. The ESP32 data sheet's pin list mentions that the chip itself can work down to 2.3V, the Espressif website claims 2.2V in the chip overview, and a post by John Lee here earlier suggested it was actually down to 2.0V. However, the data sheet's ...
Nope, no need from my direction. It was a point of curiosity since our (NodeMCU) event post function most certainly is used from ISRs (and uses the ...FromISR() versions).
@ESP_Sprite On that note, I saw that the default implementation of esp_event_send() uses xQueueSendToBack() rather than xQueueSendToBackFromISR(). Does that imply that esp_event_send() should never be called from an ISR, or are the queues safe regardless?
@ESP_iggr Regarding the interrupt allocation, I would much prefer to have you get that into master sooner rather than later, regardless of whether it's 1.0 compatible. My alternative is pretty much rolling my own and ignoring whatever you might actually provide later, because by then it'll be too mu...

You'll want to use regular printf, not ets_printf, and:
Code: Select all
Component config -> ESP32-specific config -> Standard-out output adds carriage return before newline

Whoops... indeed that was for debugging. Thanks for pointing it out - I had it on my todo list to work out why Esplorer wasn't happy loading the file list but now I know

Not quite what you asked for, but you can find the overall Xtensa Instruction Set Architecture (ISA) Reference Manual document e.g. here . It's not specific to the 108s that you'll find in the ESP32, but between the ISA doc and the components/esp32/include/xtensa/config/core-isa.h header you can pre...
