From the project

3 channel bench supply with current and voltage plotting

Integrated hardware and firmware repository for the development-station bench supply, its control electronics, front-panel display path, and supporting boards.

This is the active working repo for the full bench-supply platform, not just a single firmware target. It currently includes:

- ESP32 control firmware - DSP regulator board design - DSP regulator HAT / measurement-control board design - original front-panel display board files - USB hub board files and next-iter reference cleanup - bring-up notes, pin maps, and display evaluation references
