CY8C4014SXI-421 SPI Communication

suno_285741 Aug 18, 2017 3:20 PM

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.
