Dear Fedia,
Thanks once again for the valuable help you have rendered to me to continue with my
project. I started learning Assembly language couple of days ago, learned little bit about the MACRO.
It may sound stupid question for you but I have to ask it.
Where does this macro fits in this program? When I tried to compile the program with Pinnacle 52 it gave errors, I eleminated _RD Start to test the program.
;with macros: in asm:
_RD Start mov C,Start
_OR K1 orl C,K1
_ANDNOT Stop anl C,/Stop
_ANDNOT OVL anl C,/OVL
_WRT K1 mov K1,C

Plz note that No NPN Transistor is used yet.Only experimenting board is being used to simulate the ON/OFF switches etc.LED is used as a Output.After compiling the undermentioned program following are the observations:


- MOV K1,C .....> It is moving contents of carry bit 22h location of bit addressable RAM ie. 3rd bit of 24th Byte of internal RAM location.
-MOV P2,K1......> Moving contents of 22h of internal RAM to port2 hence, no output is generated. I think
it is a problem between Bit and Byte and I failed to rectify this prob.
Plz note that I need NO and NC contacts of K1 for simulating the alram.
plz write your e-mail address, if you don't mind.
