SPI Master and slave mode [CYBLE-212020-01]

user_483423427 Jan 17, 2018 8:56 PM

Hello,

I have a question about SPI component.

Device: CYBLE-212020-01

1) Is it possible to assign both Slave and Master to the SPI (SCB mode) component?

2) Is it possible to share the four pins (miso, mosi, sclk, ss) using in both Slave mode and Master mode?

3) If 1) and 2) are impossible, any other way?

Best Regards

Hello,

You will need to have the SCB component in unconfigured mode and configure it in firmware. There is a code example for SCB unconfigured available with PSoC Creator. Please have a look at that.

Thanks,
Hima

As HimaM_31 stated, you will need to use the SCB component in unconfigured mode, and then manually switch/set which mode you are using and when to get it to flip between master and slave modes.
