B4R Question Load default jpegs to ESP32

[RJB]

Hi,
currently I load default jpeg images to the ESP32 by putting them in programme memory and copying them to littleFS on first run.
This means there is a delay on first run, but worse than that a large chunk of programme memory is used by the jpeg files.
Is there a better way?
Thanks

Why not use a SDCard breakout board?
Should be easy enough to implement

Hi,
Thanks, yes I use an SD card for loading other images (for the premium version) but that's additional cost (and production step) so not justified for the base version.
The PCB is my own design so adding a micro SD socket is insignificant (25 pence/ cents) but the SD card/ programming is significant.
Thanks

Then consider adding an external eeprom chip

Thanks, I hadn't thought of that. Still additional programming time and cost but well worth a look.
