This example demonstrates how to use the Smart I/O™ Component in PSoC® 4 to invert the output of the serial communication block (SCB) SPI slave select signal. This method can be used for any of the SCB unidirectional signals to invert the signal polarity.

Overview

One application of the Smart I/O Component is to invert the polarity of SCB communication signals without using an external inverter. This example demonstrates how to invert the SPI Master (SCB) Component's slave select signal using the Smart I/O Component. The example can be applied to other unidirectional SCB signals (I2C is not supported).
