Using an ESP32S3 + LoRa I can receive a JPG image from a remote transmitter via LoRa into an array in PSRAM on the ESP32S3.
TFT_eSPI with the TFT_eFEX extension can then display that JPG from PSRAM onto a TFT display, using an ST7789 in this case.
The TFT_eSPI and TFT_eFEX combination does work, but I want to know if there are any alternative libraries worth looking at ?
