Hello everyone,
I'm a participant of Basic Air Data Project; I contributed to the former release of the Air Data Computer (see figure). To make a long story short, we've started to work on new design requirements, and I've encountered some critical point in dealing with the system layout.
The general idea(what I want to measure within the link) was to separate the pressure sensors board from the microcontroller (the true air data computer)
To avoid I2C clashes we decided to go with analog sensors.
At a glance, we are evaluating the following configuration
A PCB with six pressure sensors(5xELVR-L10D-F1RT-I-NA5F + 1XBARO-A-4V-MINI-PRIME ) and one multichannel data acquisition IC ADAS3022BSTZ(output SPI).
The issue is about the data link. There is no microcontroller on the sensor board. An SPI bus connects the sensor board and the microcontroller based(Teensy 3.6) elaboration unit. Well, SPI seems not suited to allow external connection with long cords(for example 3 m).
What is the HW suitable to connect the board sensor and the microcontroller together (IC driver, transceiver, etc.)?
Thank you in advance!
