#111174 - i read about putchar() Responding to: ???'s previous message |
ok...I read the putchar() C code of C51. and found that it uses XON/XOFF ...thats good for me since I wont need to do any additional protocol or extra hand/shk wires...but is this (XON/XOFF)also supported by _getkey() Code? (I could not locate the _getkey.c file or getchar.c file)...or do we need to do our own XON/XOFF when using _getkey()? and yes..I decided to do for putchar() like
//send data to computer TI=1; //for 1st byte putchar(firstchar); //first byte putchar(secchar); //second ........ putchar(tenthchar); //last one while(!TI); //wait until all ten bytes are done... this (putchar() ) will save me additional coding for handshaking "XON/XOFF" or pins (for HW handshkg)... |
