Low FPS using ESP32-S3 with 800*480 TFT Display & SSD1963 Controller


Using a custom board that contains a ESP32-S3 WROOM-1 module, we can not achieve a frame rate no higher than 4-10 FPS driving a 7" 800*480 LCD display with a SSD1963 controller using I80 mode

What MCU/Processor/Board and compiler are you using?

What LVGL version are you using? We are using LVGL 8.2.0

What do you want to achieve? Would like to know how to enable DMA transfers and the PSRAM to increase the FPS

What have you tried so far?
