A port of the AMS AS5048B Lib enabling dual I2C channels with i2c T3

Arduino library for AS5048B from AMS

v1.0 - First release
v1.0.1 - Typo to allow compiling on Codebender.cc (Math.h vs math.h) + Wind vane example modification to comply with the Timer.h lib used by them
v1.0.2 - ams_as5048b.cpp - fix setZeroReg() issue raised by @MechatronicsWorkman
v1.0.3 - Small bug fix and improvement by @DavidHowlett
v1.0.4 - Implemented OTP register burning by @brentyi
v1.0.5 - Optional parameters fix

AS5048B is a 14-bit magnetic rotary position sensor with digital angle (I2C) and PWM output. This library deals only with the I2C channel.

Features

• Manage zero position
• Counts CW or CCW
• Reads Auto Gain & Diagnostics registers
• Reads 14 bits magnitude
• Reads 14 bits angle with various units output (raw, turn, degree, radian, grade, minute of arc, second of arc, Nato mil, Russian mil, Swedish mil)
• Computes an angular exponential moving average
• Reads exponential moving average angle and outputting with various units
• Resets Exp moving Avg
• OTP setting
• OTP programming sequence

Code examples

• Single angle reading, outputs 2 units
• Angular exponential moving average reading, outputs read angle and average
• Wind vane, outputs azimuth and compass direction - This one as a special #define for Codebender.cc support
• Dial reading for X-Plane
• Slave address programming

Not available yet features

• PWM reading
