![]() "CForth" Forth interpreter for STM32G4xx, STM32F042 and STM32L476 ![]() ![]() The intention is to make a straightforward user oriented Forth system, specifically to organize interactive electronic control of art objects and installations or similar process control.
Primarily the code was developed for STM32G431KB (LQFP32), Based on this source, modified firmware versions for STM32F042 TSSOP20 and LQFP32 (also works with STM32F070), for STM32L476 Nucleo-64 and STM32G431 Nucleo-64 are provided. Veroboard compatible PCB designs are proposed. ...more |
![]() CForth Low Power version for STM32G431, STM32G441 and STM32F042 ![]() ![]() interactive control of dynamic objects powered by small solar panels or similar projects by means of the Forth programming language. ![]() The power reduction is essentially obtained by a low CPU clock (921.6kHz, optionally switchable at runtime to 3.6864MHz or 14.7456MHz) and terminal access only by RS-232 instead USB. Else this CForth version has almost the same Forth kernel features as the standard version. ![]() Appropriate hardware was developed under the aspects of saving power. Veroboard compatible single layer PCB layouts are available for download. ...more |
![]() SPI I/O expansion board for CForth compatible hardware ![]() ![]()
It can be operated with 3.3V supply or with 5V supply/3.3V logic level. A Veroboard compatible single layer PCB layout is available for download. ...more |
![]() "DTerm" terminal software for RS-232 and UDP ![]() It is surely not the best terminal emulator, but has been developed over the years for best fitness with my actual projects. ![]() The present version 3.13 is optimized for interactive upload of scripts and source code, working together with the CForth project. ![]() As a result of older projects, next to RS-232, Ethernet UDP terminal operation is supported. A lot of TCP / Telnet terminals are available, but tools for manual communication over UDP are rare. ...more |
![]() Simple digital sine wave generator ![]() ![]() The frequency range is 40Hz to 15.6 Kilohertz. With pushbuttons, three independent frequencies are selectable: default frequencies 5kHz, 1kHz, 200Hz, which is good for rapid test of audio circuits. The frequency of each button can be tuned over the full frequency range. ![]() The source code written in assembler language and schematic is published here. ![]() An additional charger for a built-in 9V block accumulator is described too. This way it is an ideal out-of-lab service tool. ...more |
