Hi

   Can you send me the code for reading and writing data into cryptomemory(slave) by using I2C in PSoC controller(master).

No.

 

What work have you done towards this task?  

Is this a school project, or professional one?

Which Crypto memory are you using?

 

Shouldn't you be asking this in the Cypress forums since you are using a PSoC?

Remember that the CryptoMemory neither knows nor cares what I2C Host you use - all it sees are I2C bus actions.

 

Similarly, the PSoC neither knows nor cares what I2C Slave(s) you use - it just performs standard I2C operations.

 

The CryptoMemory datasheet will tell you what actions you need to perform on the I2C bus, and how the CryptoMemory will respond.

 

The PSoC documentation will tell you how to perform those actions.

Iam using AT88SC25616C cryptomemory. It is a college project. I have to write informations into cryptomemory zones securely.

Sir, I have the cryptomemory datasheet. But I have no clear idea about how to write the code for this action. I just need the sample code for this.

So go to your teachers for help!

 

EDIT

 

As stated in #2, nobody is going to do your homework for you.

 

Show what work you have done.

 

If you have some specific point you want help or clarification with, then explain where you're stuck - but if you have no idea at all, then you need to discuss with your teachers.
