A lightweight framework for MODBUS RTU nodes in STM8 eForth that can do more than just I/O
This is the "here today gone tomorrow" binary release for testing.
This isn't really a release but a container for the binary artifacts from the latest build (see this GH Release issue). It's not only unstable (if tested!) but also volatile.
This means that the artifacts in the "volatile" release can be used for testing or prototyping but they won't last. In order to keep a trace to the Git version at the end of the file forth.asm
packed in the attached binary archives there is an identification record like the following:

Please take note that not all archives provided in the release are up-to-date:
File | Description |
---|---|
stm8ef-bin.tgz | full binary release, suitable for STM8 eForth Modular Build method |
stm8ef-bin.zip | binary release (out/C0135/C0135-forth.ihx is the ready-to-use "four relay board" hex file) |
stm8ef-rst.tgz | list file for debugging |
Source code (zip) | GitHub source snapshot from original tag (outdated) |

This release uses new build features introduced by STM8 eForth to 2.2.26 and Python3 support introduced by STM8 eForth update to 2.2.27.pre2.
There is experimental support for the STM8S001J3RS485 board (a binary release archive is attached). Adding more boards using this pattern is now a simple configuration task.
C0135 binary created with STM8 simulation in uCsim on Travis-CI. Tested on a "4-Relay" board V1.06.

Features:
MB address | register MODBUS | Forth |
---|---|---|
0 | holding 1 | holding |
1 .. 59999 | holding 2 | holding 2+ |
60000 | node ID | $4000 |
60001 | baud rate | $4002 |
60002 .. 60319 | user EEPROM | $4004 - $43FE STM8S EEPROM |
See #12 for discussion of missing or planned features (e.g. initial setting of Node-ID and baud rate).
Note: the tgz archive is recommended for general MODBUS use and for Forth programming. The included binary can be flashed with stm8flash -c stlinkv2 -p stm8s103f3 -s flash -w out/C0135/C0135-forth.ihx
