Participantsir
i have checked all connection and that r ok.
Tx Rx both working fine as i pressed the key from tx side, receiver led blink like chattering.
ZCD o/p connected to intrrupt 1 P3.3
HT12d 17 no pin is connected to P3.2
I m not geeting the triac pulse from microcontroller port 2^2.
i think so there is some mistake going in to the code.
Please help me

Participanthi ghuran,
many congratulations.
every keypad routine checks key debounce so once u decrease it time delay, it will not prints slow.
one more thing here in the program which u have posted is checking that if key is pressed continually it will print the no. until u release it.
other wise the program is upto date no more changes are required.
please check once again ghuran.

Participanthi ghuran,
In my previous post u did that minor changes only.
all the lcd function given in code which u have mentioned is correct.
Please see the below simulation which i have done, i think so u r suppose to missing to keep “resistor array”. i. e Pull up resistor.
b’coz Port P0 is open collector port so that it requires.
u do it this kind of arrangement it will definetely work.

Participanthi ghuran,
Please use port 0 for Data lines that is D0-D7.
I mean to say instead of sfr lcd_data_pin=0xA0; use address 0x80.
it will work. u try this & let me know.

Participanthi zammer,
First of all u need one X-or gate for comaring Frequency with reference i/p frequency.
See below i have drawn block diagram
if any more doubt please feel to ask.
