isn’t this a bit much for an old fashioned interface. my framerate drops dramatically when rs232 is activated. any ideas.
might be a winXP64 problem. well anyway, maybe someone has experienced a similar behaviour.
XP32 = 19 load in debug mode
XP64 = 140 load in debug mode
maybe a driver problem, i don’t know
RS232->USB adapters via a well-configured interface ( e.g. FTDI based ones that let you set latency manually) can often perform better than real COM ports for high-datarate applications.
