[hemnath]

It works good. and I have tested in proteus. Not in hardware.

 

[drbizzarow]

[hemnath]

Please check it.

 

[drbizzarow]

MikroC MMC library has been restricted to FAT16 (2 GB volumes). Has this restriction been overcome in recent compiler versions?

 

[drbizzarow]

Please check it.

your code is running in Proteus , i cant run it on my h/w because i am using 18f452 uc.

 

[hemnath]

I'll modify the code and send you.
What is the crystal frequency you are using?

 

[hemnath]

Please check this file. It is working in proteus. I have checked it.
