Uri’s approach uses a debugger to the JTAG on the physical hardware, a Ghidra plugin to help him work on the binaries, and his own ESP32 simulator to ferret all of this out.

This Cube project uses LED panels for a 3D physics simulation. The creator used ESP32, WS2812b control, and limited external libraries. The source code is available on GitHub, with a possible PCB ...

At its core, the ESP32 chip is not much more than an integrated circuit, a huge mass of transistors sealed inside an epoxy resin package with some leads. Of course, most of us won’t buy discr… ...

An undocumented set of low-level commands has been discovered in the ESP32 microchip, a widely used component in IoT devices. Manufactured by the Chinese company Espressif, the ...
