I need to read the data from the camera (MISO) VERY fast, while I do not need to send anything to the camera, so it would be the best if I can find a spi function that only read from the camera without writing.
I checked out the Arduino ESP32 Library here: https://github.com/espressif/arduino-esp32
The core of SPI is here: https://github.com/espressif/arduino-es ... -hal-spi.c
I noticed that there is no spi read only function. Also, the ESP32S2 technical reference manual says that I need to set the FSPI to half duplex mode and specify commands and other stuff. Is there a way that I can write a SPI read only function by myself without getting too deep into register maps?
Also, any good ideas that makes ESP32 SPI transaction faster are appreciated
