A simple SPI library to interface with Austria Microsystem's AS5048A angle sensor

AS5048A Arduino library

A simple SPI library to interface with Austria Microsystem's AS5048A angle sensor with an Arduino or an ESP32.

The sensor should be connected to the hardware SPI pins (MISO, MOSI, SCK). The CS pin can be connected to any GPIO pin but should be passed to the constructor.

as5048a's Issues

Errors: Read (0x1) with command: 0b100000000000001

Hello again,

Apologies for bothering you again. I am new to this sensor so I am learning as I go.

I have the following simple code to read the sensor and send it over serial on an ESP32.

        uint16_t val = encoder.getRawRotation();
        Serial.print("Got rotation of: 0x");
        Serial.println(val, HEX);
        Serial.print("State: ");
        encoder.printState();
        Serial.print("Errors: ");
        Serial.println(encoder.getErrors());

Unfortunately I seem to get an error and no rotation reading.

Read (0x3FFF) with command: 0b1111111111111111
Read returned: 1111111111111111
Got rotation of: 0x0
State: Read (0x3FFD) with command: 0b111111111111101
Read returned: 111111111111101
0
Errors: Read (0x1) with command: 0b100000000000001
Read returned: 100000000000001

Any insight would be appreciated.

How to set zero position?

Hello,
I am using the As5048a sensor for a project in order to measure the angle of attack of an airplane. For the connection, I use an Arduino Nano.This code works really well, but I have difficulties on setting zero position. Do you have any idea? Thanks in advance

Compile Errors ESP32

Hi,

I am trying to use your library for the esp support with an ESP32 and the AS5048A. When I compile using platformio, I get the following errors:

Any idea what the issue is here?

Thanks.
