Once the code is developed, it would be great if there was a physical way to prevent firmware rewriting (such a fuse to blow or a wire to cut)

@ajb2k3 Thank you but the screen (for Adafruit GFX) and SD card (for SD lib) have different pins : won't it be a problem if both try to use SPI with different pins in the same time ?

Hello,

I want to port an MP3 player library to carputer, but there are conflicts between cardputer.h and my mp3 library.

So what I want to do is to user adafruit gfx library and SD library directly without using carputer library. But both (gfx and SD) are using SPI with different pins. How do you make it work ?

Once the code is developed, it would be great if there was a physical way to prevent firmware rewriting (such a fuse to blow or a wire to cut)

I want to activate the esp32 "firmware encryption" feature to:

• ensure that the firmware can't be written again
• ensure that it can't be read

I know this feature exists but i would need simple instructions to activate it. Can anybody help ?

Hi !

I am using arduino to program the atom (using m5stick board settings) but I would like to extend SPIFFS size to 2Mb and reducing program size (my software needs to display images). Any idea what I should do ?
