-The AS5600 is a programmable, 12-bit high-resolution contactless magnetic rotary position sensor designed to replace traditional mechanical potentiometers. It uses Hall-effect technology to measure the absolute angle of a diametrically magnetized on-axis magnet, offering high reliability because there is no physical contact to wear out.+ 
 +The AS5600 is a straightforward magnetic rotary position sensor featuring a high-resolution 12-bit analog or PWM output. It measures the absolute angle of a diametrically magnetized on-axis magnet without contact. Designed for contactless potentiometer applications, its durable build prevents interference from external homogeneous magnetic fields.  
 + 
 +The industry-standard [[com:basic_i2c|I²C]] interface allows easy programming of non-volatile parameters without a dedicated programmer. By default, the output covers 0 to 360 degrees, but a smaller output range can be set by programming a start (zero) and stop (maximum) angle.  
 + 
 +Additionally, the AS5600 includes a smart low-power mode to automatically lower power consumption. An input pin (DIR) determines the output polarity based on rotation direction: connecting DIR to ground causes the output to increase clockwise, while connecting it to VDD causes it to increase counterclockwise.

 +**Critical Usage Notes**
 +
 +  * **Operating Voltage:** When powering with 5V, make sure the module's onboard voltage regulator (if available) is used properly. For the raw chip, Pin 1 (VDD5V) and Pin 2 (VDD3V3) have specific wiring needs for 3.3V versus 5V operation.
 +  * **Pull-up Resistors:** The I²C lines (SDA/SCL) need pull-up resistors (typically 4.7kΩ) to VCC if they are not already present on your specific module.
 +  * **DIR Pin Stability:** It is strongly advised not to leave the DIR pin floating. Connect it to GND or VCC to avoid erratic position readings.
 +  * **PGO Pin:** Some modules include a resistor between PGO and GND that may disable the OUT pin. If the analog/PWM output isn't working, check this connection.

 +=== AS5600 Arduino example code ===
 +To read angle data from the AS5600 using an Arduino, the most reliable approach is to use the I²C interface. You can use a library like the **Adafruit AS5600 Library** or the **Rob Tillaart AS5600 Library** for simplified functions.
 +
 +This code initializes the sensor and prints the angle in both raw units (0–4095) and degrees (0–360°) to the Serial Monitor.
 +
 +<code c>
 +#include "AS5600.h"
 +#include "Wire.h"
 +
 +AS5600 as5600;
 +
 +void setup() {
 +  Serial.begin(115200);
 +  Wire.begin();
 +
 +  if (!as5600.begin()) {
 +    Serial.println("Error: AS5600 not detected. Check wiring!");
 +    while (1);
 +  }
 +  
 +  // Set clockwise as the increasing direction
 +  as5600.setDirection(AS5600_CLOCK_WISE); 
 +  Serial.println("AS5600 Initialized.");
 +}
 +
 +void loop() {
 +  // Read raw 12-bit value (0-4095)
 +  uint16_t rawAngle = as5600.readAngle();
 +  
 +  // Convert to degrees (360.0 / 4096.0)
 +  float degrees = rawAngle * (360.0 / 4096.0);
 +
 +  Serial.print("Raw: ");
 +  Serial.print(rawAngle);
 +  Serial.print(" | Angle: ");
 +  Serial.print(degrees, 2);
 +  Serial.println("°");
 +
 +  delay(100); // Read every 100ms
 +}
 +</code>
 +
 +**Key Functions**
 +
 +  * **as5600.readAngle():** Returns the current 12-bit filtered angle.
 +  * **as5600.getMagnetStatus():** Returns a status byte (//0x20 = Magnet detected; 0x10 = Too weak; 0x08 = Too strong//).
 +  * **as5600.setDirection():** Allows you to flip the rotation direction in software if the DIR pin is left floating or controlled by an I/O pin.
 +
 +**Troubleshooting**
 +
 +  * **Magnet Detection:** If the serial monitor displays constant values, verify the magnet distance (0.5-3mm).
 +  * **Address:** The I²C address is fixed at 0x36 and cannot be modified.
 +  * **Pull-up Resistors:** Make sure your module has pull-up resistors on SDA/SCL, or add 4.7kΩ resistors to VCC if the I²C scan fails.
