Hi Everybody.

I'm new to PICs and I was wondering if somebody could help me with the following:

In circuit I'm using pic16f877 that writes 8 byte in eeprom 24lc512.
Everything works fine but I would like to encrypt the data before writing them to the eeprom.

I decided to use TEA algorithm because it takes only 240 words and 33 byte of RAM.
Here is some explanation about TEA algorithm and here is the code written in assembler, version 1.3 of TEA including test program for 16f84.

So, my problem is that I don't understand assembler. Trying to use the instructions ASM....ENDASM at the beginning and the end of the program I couldn't compile even the test program (teatest.asm).

I would appreciate any help or piece of code you can give me.

Thanks in advance.
