I want to connect several SPI Slaves to the Master. The MASTER only has one Chip Select pin and i am looking for a decoder which can give several Slave Select Outputs.
Any suggestions? The datasheet of ADG725 at Page 15 describes the similar situation : https://www.analog.com/media/en/technical-documentation/data-sheets/ADG725_731.pdf
Using a generic 2 to 4 but decoder is an option if only 4 /sync lines are needed. You would have to control the decoder with 2 GPIO inputs to select the desired device.
