STM8 eForth Example Code
This page provides a list of STM8 eForth projects and demos. There is also some example code in the STM8 eForth Programming mini-tutorial and on other Wiki pages. Code examples are a source of inspiration, so please add your code to the list. The STM8 eForth project, by the way, encourages the use of permissive Open Source licenses, e.g., MIT, MPL or BSD.
Projects contains work that provides some "real world features".
Note that the W1209 data logging thermostat also is a showcase project that demonstrates the code density that can be achieved with embedded Forth.

This section contains building blocks for applications. @Eelkhoorn's STM8 Peripherals library really is worth checking out.
Note that an alternative version of the nRF24L01 library is here.

Mods are code that modify or enhance core features of the STM8 eForth kernel.
| Title | Author | Type | Note |
|---|---|---|---|
| VOC | M. Mahlow | mod | Namespace-like extension based on the CURRENT wordlist feature (more here) |
| INTRX | tg9541 | mod | Buffered UART receive for the Forth console |
Examples in docs, prove-of-concept code and solution snippets go here. Some of the demos are quite elaborate and can be used as starting points for projects (e.g. the CN2596 power supply or the W1209/HC-SR04 ultrasonic range meter).
