For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory. Source: 10 months ago

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino. Source: 11 months ago

PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats. Source: about 1 year ago

Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards. Source: about 1 year ago

If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO). Source: about 1 year ago

I also use Caesium Image Compressor on my ROMs and Themes folder to reduce their size and improve the RG35XX's responsiveness. Source: about 1 year ago

If you want further compression you could check out Caesium Image Compressor which is free (and I'm not affiliated with it incidentally, I just like it). Source: over 1 year ago

Try an image compression tool, this one is free and open source: https://saerasoft.com/caesium/. Source: over 1 year ago

Caesium Image Compressor can do the job and it is easy to use. There is also imagemagick which is basically the swiss-knife for image editing, but based on you having looked for websites first, I assume you don't look for a commandline tool (imagemagick is a commandline tool).

I can recommend Caesium , a utility (Windows, MAC version in Alpha test) to remove all EXIF, metadata etc which will reduce your JPG in size quite a lot without using higher JPG-compression (lower quality). Source: almost 3 years ago
