• Manufacturer Part Number: MLX90333KGO
• Description: Triaxis 3D-Joystick Position Sensor
• Manufacturer: MELEXIS [Melexis Microelectronic Systems]

The PWM frequency is selected by the PWM_Freq parameter.
For instance, in Low Speed Mode, set PWM_Freq = 7000 (decimal) to set the PWM frequency at 500Hz.
14.2.3. Serial Protocol Output Mode
The MLX90333 features a digital Serial Protocol mode. The MLX90333 is considered as a Slave node.
See the dedicated Serial Protocol section for a full description (Section TBD).
14.3. Output Transfer Characteristic
14.3.1. The Polarity and Modulo Parameters
The angle Alpha is defined as the arctangent of X/Z and Beta as the arctangent of Y/Z. It is possible to
invert the polarity of these angles via the parameters ALPHA_POL and BETA_POL set to “1”.
The MLX90313 can also be insensitive to the field polarity by setting the
ALPHA_MOD180/BETA_MOD180 to “1”.
