OK, perhaps I'm on to something (my own mistake 😬).
I'm using a chip called AI Thinker-A1S, which I'm sure I've read somewhere should be compatible with the Espressif ESP32-WROVER (which uses the IOs MaBe mentioned), but I can't find that information now.
Reading the datasheet of the AI Thinker-A1S, it looks like the IOs used for SPI is a little different though; MISO is IO21 and not IO19 (although they use a terminology like
VSPIIDHS1STROBEinstead ofVSPIDas the WROVER does).Is there anything I can do to make HW SPI work on this device?
