Hi,
I need to acquire 2 PT1000 and 2 Resistance with myRIO for my application.
In order to achive a good measurements I thinked to implement a 4 wire measurements for the PT1000, and the resistance trought a MAX31865 device.
The MAX31865 has a SPI interface, so my question is how can connect 4(or more) SPI devices to myRIO?
Infact myRIO has only 2 SPI( one for the A MXP and one for the B MXP).
Can you show me an example of code to manage this four devices?
regards
david
