That board won't give you enough information to do a nice FFT on... you probably want to use a real microphone and connect it to i2S instead. I saw the i2s microphone thread and it looks far more complicated to setup than a mic on analog pin. would MEMS microphone give enough sound detail for a nic...

thanks Kolban I will use it

LVDS would expand our display options and would require a 2D accelerator https://www.reddit.com/r/esp32/comments/8fo64o/how_to_connect_a_b101xan020_to_the_esp32/ If it's possible, a section of the chip is an FPGA then we'd have possibly super high speed IO, but FPGA would have to be configurable by ...

I am trying to connect this screen to the esp32 WROOM devboard. No luck so far. This is the error for TFT_eSPI when TFT_graphictest_one_lib runs // Parallel bus is only supported on ESP32 // Use ESP32 Parallel interface instead of SPI #define ESP32_PARALLEL // Only define one driver, the other ones ...
