ESP32-S3 Series

[gin66]

This device contains mcpwm module, but only 4 instead of 8 pulse counters.
Thus 4 steppers should be possible to be supported.

Anyone available for test, so an update of the driver makes sense ?

Sure, I'm available to test if you like.

Just tried a quick compile for S3 from master on an existing large project (SmartSpin2k). Relevant platformio.ini:

platform = https://github.com/tasmota/platform-espressif32/archive/refs/heads/IDF44/ESP32-S3.zip
board = esp32-s3-devkitc-1
framework = arduino

errors (Probably because you haven't implemented anything yet):

Thanks for your willingness to test on esp32-s3. Please be patient, because these days I am quite busy. Hope to start on the adaptation within the next two weeks.

The driver already supports rmt in addition to mcpwm+pcnt. This means, two possible paths to follow. During the adaptation will see, which path generates the least effort.

Hi guys, any progress on this? At least idea about which direction to go?

Okay, I dis some changes and have a version that works with ESP32S3. Should I create PR?

[gin66]

sure. Looking forward to this

Hello Martin,

Can you share your modifications?
I will be migrating a project soon to the esp32-s3 and it would be of great help.

Hello gin66,

I made some changes to allow support to ESP32 S3 and made a pullrequest (ESP32 S3 MCPWM/PCNT Support #162).
It is the first time that i make something on gihub so i hope not to have missed something.
I am available if you need some specific tests to be done.

Thanks for the patch. I have merged in and the github action to build the sw has worked.
So I release it with 0.28.4
