#99117 - chip being used Responding to: ???'s previous message |
I am using a chip called the ICE51, which I guess is a clone of the 8051 bt still does the same job.
I have a Counter Example code here which Count the pulses on pin T1 (P3.5) and display the counter value on P2. START: mov TMOD, #01100000B ;counter 1, mode 2, C/T=1 mov TH1, #0 ;count from 0x00 to 0xFF setb P3.5 ;configure P3.5 as input AGAIN: setb TR1 ;enable counter BACK: mov A, TL1 ;read TL1 value mov P2, A ;display it on P2 jnb TF1, back ;poll for TF1, could use INT1 also clr TR1 ;stop counter clr TF1 ;clear TF1 flag sjmp AGAIN ;while(1) But what i would really like is to get this information say from PORT 2, and then have it sent back to me through the serial cable and displayed onto my pc screen (monitor). help if u can! |
