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.
