What spi_bus value to use in slave.begin() for ESP32-S3 based modules?

Closed this issue a month ago · 2 comments

When using an ESP32-S3 based module for my device, what value for spi_bus should I use in slave.begin()? Should it be "FSPI" if using SPI2 and "HSPI" if using SPI3? Just want to make sure I'm reading your readme file correctly. Thanks.

Hi @karunt

As mentioned in the README, the default SPI is HSPI, and the pins are (MOSI, MISO, SCK. SS) = (11, 13. 12. 10). However, you can change them independently and flexibly. Using the default one is good if you don't need to change them.
