Hello,
I want to interface to WICED wifi module a display and SD card, both work on SPI. As there is only one SPI available, how to multiplex?
Can i use soft SPI for one of them? Any examples?
Thanks,
Raghu

You can use a single SPI tied to both your peripherals and use the GPIOs to control the chip select lines for both you peripherals. This is how SPI with multiple slaves is usually done.
