Encoder Pulse Missing-TMS320F28379D MCU

Dear Team,

We are currently using the Altair Embed 2024 license version.
While reading the encoder (GPIO24 & GPIO25) using the TMS320F28379D in our own microcontroller , we are experiencing missed pulse counts.
(Our motor has a tick count of 4000 per full rotation)


Ideally, the tick count should go from 0 to the maximum for one full rotation, but we are missing around 200 tick counts. Additionally,we have attached vsm file.

Regards,

Reshmi R&D Team.

    What is the make and model of the encoder you are using? Is it a 4000 pulse count encoder?

    If it is an incremental encoder you should enable the index pulse.
