#99214 - Created a program! Responding to: ???'s previous message |
I have made this program so far, with the serial and timer/counter configurations on. Unfortunately it doesn't seem to work.
ORG 0800 SJMP START ORG 800H START: MOV SCON,#00010000B ;MODE 0, RECEIVE ENABLE (REN) MOV PCON,#0 ;set SMOD to 0, no doubling of baud rate mov TMOD, #01100000B ;counter 1, mode 2, C/T=1 MOV TH1,#0FDH ;hex FD into timer high byte to define 9600 baud rate mov TH0, #0 ;count from 0x00 to 0xFF setb P3.4 ;configure P3.4 as input AGAIN: setb TR0 ;enable counter BACK: mov A, TL0 ;read TL0 value mov SBUF, A ;display it on P2 jnb TF0, back ;poll for TF0, clr TR0 ;stop counter clr TF0 ;clear TF0 flag sjmp AGAIN ;while(1) Can anyone see where I am going wrong, please help! |
