Node SW ver 3, basics tested ok (boots, relays, reports errors).
BMS node: Code size optimization, debug LED mode is back, selectable ext sens pull-up
Channelfifo: Replaced status byte with standard comm error message w/ addr 253
Short measurement now averages 4 values (10 prgm bytes saved). +0.3 ms (of about 8 ms)
Get EEPROM write access command does not reply anymore.
Full calibration in node SW. Added calibration testing program for PC.
Simple calibration at node. Not fitting currently. Started optimizing and removing unnecessary stuff.
BMS node with old EEPROM style, 2204 bytes
Made it to 2030 bytes! Changed EEPROM checksumming, removed totally irrelevant features, etc.
Optimized manchester receive a little bit. Some self-diagnosis took it over the limit again.
2018 bytes. All features needed are there. Testing&debugging & timing re-finetune left.
