@debsahu @me-no-dev Well, I did some testing, and Esp32 using hardware SPI no longer works. It did at one time but there seems to be an issue where it is not sending all the data.

@debsahu It seems there is an SPI bug on Esp32/Esp8266 IDF that either got injected or changed to fix something; and that the frequency that data can be sent out safely is 1/5th of what it used to be able to handle. I changed my code to work around the problem and merged in the exposing the SPI pin selection that are available on Esp32. A new release is still weeks out but you can just get the repo if you want to work with it early.

But currently, on Esp32, the speed difference between bitbang and using SPI is pretty minor (see FAQ)
