How do I make 9356SPI work
PostPosted: Mon Oct 16, 2006 4:20 am     Reply with quote
Hello

I have a problem on using the 93LC56A eeprom with my 16f877A. I have used it with software and it works fine. Now that I need to use it with hardware, it doesn't work.

At first, why is the READ command 0xc on software include file and 0x18 on SPI-hardware include file?

I changed it to 0xc!!! ( it didn't work then, i doesn't work now Evil or Very Mad )

As I have seen the problem might be this
The value stored on address 0 is 92 but i get value 46. It seems that there is a 1bit shift to right (div by 2). I just don't know why this happens.

Please help! pleasepleaseplease

Does this mean Proteus ? That's a simulator.

What are these two files ? I assume one of them is the 9356.c driver
file. What is the filename of the other file ? Is it a CCS file, or a
Proteus file ? I can't give you any help on Proteus.
