OW 2.8p20 (self compiled)
LCD - hobby boards interface.
Passive 1W adapter on RS-232. External +5V.
Only clear for LCD_H working. Nothing else.
Same circiut with 2.8.13 working partly:
- clear OK
- message 1-4 chars - OK
- message > 4 chars - NOT OK. Something else showing on LCD.
I would be grateful for your help.
