MCT8316Z: MCT8316Z SPI config

Chetan Urabinahatti
Prodigy 10 points
Part Number: MCT8316Z

Hello,

I basically need support for two aspects:

1. How to read the FGout signals in a microcontroller? What signal corresponds to what value and how to configure? 

2. How to set the Direction output in a SPI version.

Please help me by giving detailed information if possible. 

Highly appreciated for your valuable time.

    Hi Chetan,

    The FGOUT signals frequency is used to represent the electrical speed of the motor. Section 8.3.15 of the datasheet shows the effect of the FGOUT_SEL settings, bits 7-6 of Control_Register_8, which are used to set a division factor. To see an example of how to convert the FGOUT signal into Hz using a microcontroller, you can refer to our MCT8316Z Firmware.

    You can set desired direction using the DIR bit (bit 0) in Control_Register_7. By default the motor direction will be set to clockwise (0b), 1b is used to set the motor direction to counter-clockwise.
