I have a RTC running as the main loop,displaying the time in hr:mi:s in an
LCD.Now I want to use this RTC minutes for
a time delayed triggering of a remote control.The delay is for a minute or so ,no need to be accurate.When P1.2 is pulled down
momenterly the RC command no:1 should execute
and after the minute delay Rc command no:2
should execute ,this is the purpose
So in the main time loop
I have added this lines for triggering the
RC.
JNB P1.2,SET_REM
SET_REM:
JNB P1.2,SET_REM
LJMP IR_SEND

IR_SEND:
PUSH ACC
SETB IR_FLG ; a flag is set for main
loop for checking
ACALL REM_COM1;IR command 1
MOV r0,#2Dh ; Minute store location
MOV A,MINS ; MINS is the reg where
the minutes are recived
from the RTC
INC A ; For a minute delay
MOV @r0,A
POP ACC
AJMP COMP; Is the compare code which
is added to the main loop
COMP:
MOV A,MINS
MOV B,@r0
CJNE A,B,TIME;jmp back to time
ACALL REM_COM2;IR command 2
clr IR_FLG
AJMP TIME

Now my problem is the IR command no: 2 is not being executed after the delay comparison,In the main time loop the line of code JNB IR_FLG,TIME
is added to check the P1.2 is activated.The IR command no: is being executed
The RTC (which is a DS1307)which is connected through I2C is displayed ok in the LCD and the remote commands are RC5 which is working fine when tested independently
Can anyone please help me,Thanks in advance.
