+Forth is a "low level" language that supports a high level of abstraction. Due to the code density that can be achieved Forth is well suited for embedded control. Since data flows through the stack there is no need for temporary variables which greatly reduces complexity.

+## About STM8 eForth
+
 STM8 eForth is highly configurable: a minimal interactive system fits in 3.5K and a full featured binary requires 4 to 5.5K Flash memory. Due to the extraordinary code density a low-cost 8K device, e.g. [STM8S003F3P6](https://www.st.com/resource/en/datasheet/stm8s003f3.pdf) or [STM8L051F3P6](https://www.st.com/resource/en/datasheet/stm8l051F3.pdf) has sufficent space for applications. If that's not sufficient, low-cost 32K devices with many GPIOs or a richer set of peripherals can be used, e.g. [STM8S005C6](https://www.st.com/resource/en/datasheet/stm8s005c6.pdf) or [STM8L052C6](https://www.st.com/resource/en/datasheet/stm8l052c6.pdf).
 
 The Forth console uses the STM8 U(S)ART or a simulated serial interface for communicating with the console (3-wire full-duplex or 2-wire half-duplex are supported). For console access and programming [e4thcom](https://wiki.forth-ev.de/doku.php/en:projects:e4thcom) is recommended but any serial terminal will work. The console can be configured, even at runtime, to use other types of [character I/O](https://github.com/TG9541/stm8ef/wiki/STM8-eForth-Board-Character-IO), e.g. keyboard and display.
