ESP32-S3 LCD with quad PSRAM
Posted: Fri Sep 09, 2022 8:13 am
Dear,
there is support for the LCD controller and LVGL on the IDF, with an example https://github.com/espressif/esp-idf/bl ... ple_main.c
But this page says, that a octal PSRAM is required (or just suggested). For now, we have the ESP32-S3-WROOM-1-N8R2, what have just 2MB PSRAM and quad lines. Our boards will arrive in 2 weeks, so I cant try it right now.
Question is, can quad PSRAM modules used as well for the ESP IDF LCD driver? I understand, that the memory bandwidth is lower, so the refresh rate will be lower, too. But will it work with reduced refresh rate, with the ESP32-S3-WROOM-1-N8R2?
Thank you
