ESP32 P4 support?

[dmitrybakaev]

The ESP32 P4 is a powerful new asset within the Espressif family that we're considering switching to. It would be great if FastAccelStepper supported it.

The latest rmt driver is hardware agnostic - enforced by espressif - and consequently should work.
There is currently no platformio support for esp32p4, so build can not be tried.

I was able to run P4 at platformio, with extra configuration of platformio.ini:
[env:esp32-p4-evboard]
platform = https://github.com/pioarduino/platform-espressif32/releases/download/53.03.11/platform-espressif32.zip
board = esp32-p4-evboard
framework = arduino
monitor_speed = 115200
build_flags =
-DCORE_DEBUG_LEVEL=5
-DARDUINO_USB_MODE=1
-DARDUINO_USB_CDC_ON_BOOT=1

Thanks. P4 compiles, but I am not sure about the rmt configuration. I have assumed 4 channels with 64symbols each.

Found the appropriate SDK values. If you own the P4, please give it a try.

@gin66 It works like a charm! This is literally the fastest fix I've experienced on GitHub 😊 Thank you so much for your incredibly quick response - FastAccelStepper is truly an amazing asset for getting the job done efficiently. I'm very grateful for your support!
