Best approach for sharing SPI bus across multiple sensors

The best approach would be to use SPI-controlled switches like ADGS1408 to select slave device on sensor PCB. This way same bus will be used for both ...

How to share the SPI bus between multiple devices? (SDSPI, NVS ...

Our preference is to have the NFC on a separate SPI bus and both the ext flash and SD card IC's on a shared bus. But how do we share the access ...

How to use SPI for multiple devices - Arduino Forum

jremington: Each device on the SPI bus must have a SS "slave select" or CS "chip select" input. You need to get each part ...

Best way to use an RTOS with multiple parallel SPI peripherals?

If you have to read all of the sensors before you send and all of the sensors are sharing the same SPI bus then you aren't really getting any ...

SPI and multiple and different types of sensors - Arduino Forum

Mind each device input loads the SPI bus with a capacitance, which adds. So your capacitance is 16x bigger than with a single device. Try to use ...

Multiple devices on the same SPI bus but with different SPI configs

It depends on your specific devices. Some ignore the clock and data lines while not selected and some don't and will get ''confused''. For those, you can ...
