I downloaded the rar file but when i write hex in mcu_2 for door look in mcu(AT89C2051) it gives error while verifying."Verify failed at Byte 2 ".
But the Hex for mcu1 sensor writes and verify succesfully after programming.

Please help with the mcu_2 door lock hex

@James, can you please try with the newer hex file. Actually the hex file inside is generated from unregistered version of keil. so file does not suits well for AT89C2051.

Where is the newer hex file you are talking about?

@senyora, its already updated in the zip file.

Thankyou so much! :)

Is there something wrong in the program(hexfile) ? It doesn't work.

how can i check the hex code whether it is correct or not?
plzzzzzzz help me..

@Arush, Well you need to test it or simulate it for better idea.

I have the C code of the project 'GSM based home security' bt when i ran this code on keil it shows some error but i did't able to detect the error and i also got a hex code bt dont knw wether it is correct or not ...What can i do to get the correct hex code so that i can make my final year project....plzzzzz help me

@Arush, please post the problem/question in forum. Do mention where you got the project from.
