| No, I don't see what you mean.
Do you mean that... 1) the other component sends a series of ASCII characters that are either 1's or 0's 2) it sends a single ASCII character that is made up of ... |

Forum: General CCS C Discussion Posted: Thu Apr 21, 2005 4:18 am Subject: RS232 Sending and receiving bytes |
For individual bytes use getc to get a char, and putch to output a char. (or is it getch and putc?!  )
ANDing the char with 0x01, 0x02 is indeed the way to go, to check bits. char c ... |

| There are various SRs (HC595 comes to mind), but (depending on LED type) you can run the sink from an HC373 latch (rows) and then source from a P channel mosfet array or a driver chip (columns). Latch ... | |

| Mark, thanks for that. Damn! Forgot about the dreaded interrupt setup time!
I guess the only way to poll kbhit at '10 times the bit rate' for a 9600 baud soft UART is to do it in a tight loop? |
