mlx90333 Melexis Company, mlx90333 Datasheet - Page 20

• Manufacturer Part Number: mlx90333
• Description: Triaxis? 3d-joystick Position Sensor
• Manufacturer: Melexis Company

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.
The frame layer type is defined by the parameter XYZ as described in the next table.
See the dedicated Serial Protocol section for a full description (Section 16).
14.3. Output Transfer Characteristic
The 3-Points parameters allow the user to use the 3-points mapping (4 segments). This mode can only be
used for Mainmode equals 2 and 3.
