Description
The RAA2P3200 is a magnet-free, inductive position sensor IC designed for absolute rotary, linear, or arc position sensing in industrial applications. It operates on the principle of eddy currents, detecting the position of a simple metallic target that is moving above a set of coils, comprising one transmitter coil and two receiver coils.
Inductive sensing technology offers significant advantages over magnetic technology, including greater flexibility, easier system integration, and enhanced performance, reliability, and cost efficiency. As a result, it is becoming the preferred choice for a wide range of industrial applications.

The CRC code provided in the RAA2P3200 programming manual is incorrect.
Only calculating the all-zero commands for reading the sensor is incorrect. I tried all 8 CRC results of the all-zero command and found that the chip internally recognizes 3, but the code computes 1 (seed=0b101) and 2 (seed=0b1).

RAA2P3200 out1(pin13) always drive down.
I have build RAA2P3200, and try to take with microcontroller (rp2354)however, pin out1(pin13) always drive down. The voltage and internal voltage (1.8v) is fine, TX is out.But pin out1 and out2 is always drive low. The rp2354 microcontroller is driving uart protocol, without connected to out1 ...
