I've recently bought a battery charger from Conrad (Voltcraft Charge Manager 2020).
Overall it is doing a good job but it has some limitations that I would like to bypass by modifying its
firmware.
I have been able to obtain the schematics for this charger and it is using a MC68HC908GT16 chip.
If I'm not mistaken, this is the same chip as the one used for CC2.
On the schematics, there are pins labeled "Monitor Mode" and "Monitor Data". I've read part of the
chip's datasheet and the Monitor Mode is apparently the way to access the flash (READ / WRITE) of the
MC68HC908GT16.
I suspect that this charger is *somehow* compatible with the C-Control tools. Maybe these tools can be
used to read and write the flash of the charger.
Would anyone happen to know how I could interface this charger with a PC (RS-232)? Are there
ready-made C-Control interfaces to do the job? Is there software as well?
Thanks
