Hello:
I'm trying to use a serial port to activate a leds panel playing three
lines. I decided to do this way: one to send the data (RTS), another one to
use it as a data clock (DTR) and another one when the data frame has
finished (Tx with bit stop).
It works fine, but it is not quick enough. I can send about 50 bits every
millisecond using DTR and RTS, and using Windows CE it's worse. Maybe the
problem is in the api EscapeCommFunction, but I'm not sure.
How can I use these lines without any internal process, only to fire pins of
devices?
Should I use a parallel port?
Thanks in advance for your help
Best regards
