Hello,
I am working on some LDmicro enhancements for my Controllino Maxi based CNC project (this is an Arduino PLC).
I have added a new extended interpreter with compressed bytecodes to save memory. I have a first release of Controllino software able to interpret those new bytecodes.
The ladder program can be easily updated via Ethernet thanks to a small Web GUI. That is more flexible than .ino compilation and USB flashing.
The LDmicro modified code is here:

I am now working on MODBUS integration.
Stay tuned!
Frederic.
