    Seed7

    Interpreter and compiler for the Seed7 programming language.

    Interpreter, compiler, libraries, documentation and examples for the Seed7 programming language. Seed7 is a general purpose programming language. It is a higher level language compared to Ada, C/C++ and Java. In Seed7 new statements and operators can be declared easily. Functions with type results and type parameters are more elegant than a template or generics concept. Object orientation is used where it brings advantages and not in places where other solutions are more obvious. Seed7 spares no effort to support portable programming. Several driver libraries assure that the access to operating system resources such as files, directories, network, clock, keyboard, console and graphics are done in a portable way. Although Seed7 contains several concepts from other programming languages, it is generally not considered a direct descendant of any other programming language.

    Tachyon Forth

    Tachyon Forth

    A fast compact commercial quality Forth for embedded MCUs

    Tachyon was originally developed for the Parallax Propeller 8-core MCU because I need to do more and faster, and within the the limited memory, in order to produce firmware for my commercial embedded hardware products. When the much vaunted successor, the P2 was introduced, then Tachyon was upgraded and also built into the P2 ROM as TAQOZ. Source code can be sent or pasted from the PC terminal at high speed (921,600 default) without any terminal delays and compiled into RAM ready for backup into SD or Flash. TAQOZ RELOADED, the full version of Tachyon for the P2 can be booted from SD cards or Flash and has all the tools needed to develop and test code interactively on the target MCU. Please browse the wiki pages for howtos and information on all matters regarding Tachyon/TAQOZ and the P1 and P2. There's even a Tachyon layer that runs on Mecrisp on the RP2040 too and now the ESP32-C3 as TachyonESP which uses the Arduino IDE to build the kernel.
