Hi

   

I used CY8C4014SXI-421 for the touch key.

   

I have used I2C slave for the serial communication.

   

 

   

my customer want to using SPI for the serial communication.

   

I know the CY8C4014SXI-421 have no SPI Block.

   

but I have to make SPI for the customer.

   

Can I make SPI using CY8C4014SXI-421?

   

 

   

Thanks

You can always bit-bang the SPI protocol in software. Its not as fast and nees CPU time, but it works.
