Blueteeth said:Bit banging with that would slow things down, but we're still taking 2400bits/s (800 bytes/s - think thats 0.13s to update the array). With a PIC, or anything with a hardware UART, it'll be much quicker. I guess it all depends on cost, time, constraints of the system, and what area's you are skilled at.
justDIY said:Why do you say bit-banging the port would slow things down to 2400bps?
The serial port is just that, a serial port - the bits get shifted out, one at a time. The parallel port can output an entire byte in one clock tick.
I guess it all depends what type of latency there is in your method of talking to the port?

ps. After reading that over, Microchip should start sending me cheques...
