So, there is very difficult code with 7 tasks (lcd screen, terminal interface, udp, lamps, etc.). It's a problem for me to describe my situation in details.
But there is 1 thing:
When I write ES = 1 I see such a situation:
- lcd screen never works fine;
- other tasks work fine, until some moment;after this moment I see in 'Call stack' window at least 12 calls and nothing works (sometimes controller tryes to execute unexistent instruction).It seems to me, that there is stack overflow...
