Nigel Goodwin Super Moderator Most Helpful Member Jan 10, 2008 #2 It's already binary - do you mean you want to convert it to 8 bit parallel?. Easiest way is to use a PIC, but you could use an old hardware UART? - but that's a big chip and requires a lot more support components.

S Speakerguy Active Member Jan 10, 2008 #3 He might also need ascii->binary conversion too. I agree, a PIC would be best.
Papabravo Well-Known Member Most Helpful Member Jan 10, 2008 #4 A shift register and a state machine should do the job. You could use an FPGA or a couple of PALS.
