Hello to all, I'm having a problem that appears when trying to get data from an AD7768 ADC. I need to read data using the ESP32 as a slave on the VSPI bus. I'm configuring the SPI bus and the transaction as in the example, deleting all that I do not need. Also, I only have a MISO pin because ESP32 d...

Maybe not useful for you... But, I had similar problem few months back. Turns out I was using pin 9 for CLK. Following change worked for me... If you go to $IDF_PATH/components/esp32/spiram_psram.c There is a define: #define PICO_PSRAM_CLK_IO 6 I changed this to #define PICO_PSRAM_CLK_IO 9 ...and i...

ESP32-PICO-D4 external SPRAM

Hello and thanks in advance I was trying to understand why I can't add my external PSRAM working with my ESP32-pico-d4 chip I'm using ESP-IDF v4.0 with eclipse. My PSRAM chip is LY68L6400 and is connected as described below: PSRAM ESP32-PICO-D4 CS IO17 (pin 27) SCLK CLK (pin 31) SIO0/SI SD0 SIO1/SO ...
