SC16IS762 as UART slave & SPI master

[mikecarlos]

Hi,

My aim is to control 3 SPI devices on a single board from a host which is connected to the board over UART.

Is this possible using SC16IS762?

In more detail, I want to access the registers of SC16IS762  over the UART interface from my microcontroller, configure SC16IS762  and also communicate with the three slave SPI devices over SC16IS762.  I assume I can configure the GPIOs as CSB signals for the SPI interfaces.

Regards,

Mike

Hello Mike,

Your assumption is correct, you can control 3 SPI slaves through the SC16IS752, but the limitation is that you must implement two CS using the GPIO's from the device. As long as you have a solid UART communication with your micro-controller you can surely accomplish this.
