This folder contains the STM8 eForth configuration files for the first mod of a "cheap DC/DC converter with voltmeter".
Documenation for this first board is in the Wiki.
In the meantime other boards became more readily available:
For the DCDC-MH board there is additional information on Hack-a-Day, and a GitHub Gist with an initial DCDC-MH STM8 eForth configuration.
The DCDC-MH board is powered by a pin-to-pin replacement Nuvoton chip, and converting the board for STM8 eForth requires some soldering skills. The conversion is still worth it since the design is well suited for implementing a serial console.
The schematics of the DCDC-MH board was "reverse-engineered" :
An analysis of the linear power supply for the µC circuit shows that the board has a wider supply range than earlier DCDC-with-voltmeter modules.
