spojeni dvou vypisu RS232 do jednoho

[Naprstek, Jiri]

Dobry den,

   delal jsem pred casem zarizeni, ktere by podobnou funkci dokazalo plnit - 8 seriaku dovnitr, 1 ven. Manipulacni SW chodil tak, ze tech 8 vstupu bufferoval a vysypal na zadost z PC (tato funkce by sla vyhodit, pak by to sypal ven rovnou). S ohledem na to, ze cele zarizeni plnilo jeste dalsi funkce, tak by se to do 1kkc neveslo, ale nejaka debilizovana verze urcite (soucastky odhadem do 300,-). Jadrem byla jedna motorolka 68HC908GT16.
   Muzu Vam dat schemata i SW, popripade pomoct s tou debilizaci. Mate v umyslu to stavet, nebo koupit hotove? Kolik kusu byste potreboval?

Jirka N.
