TIDA-01401: Absolute Encoder Position reading between TIDA-01401 and LAUNCHXL-F28379D Code

Hi Nizam,

The two pieces of THVD1550 are the RS-485 transceivers.

Please refer to the diagram in the first page of the SCH.

Hi Shan,

I know first page;

However this connections don't connect to 2 different USART pins. Connections are below;

also RX CLK and TX CLK connected to PWM channels pins. I am wondering how to write code to TMS320F28379D with RX CLK and TX CLK to RS485 communication.

Best Regards.

Hi Muzaffer,

Refer to the datasheet of the MCU, GPIO63/GPIO64 can be configured to SCITXDC and SCIRXDA: 

May be you can use this confiduration.

Best regards,

Hi Shan,

I have already checked this configuration.

I understand that there is no reference code or example code related to this product.

Thank you for not being able to help.

Is there anyone who can share reference code or example code related to this product besides Jerome Shan?

Best Regards.

Hi Muzaffer,

I am sorry not catching your question. Not sure what kind encoder are you going to use. Here we have one for T-Format. Please refer to this document: 

TIDM-1011 (Tamagawa T-Format Absolute-Encoder Master Interface Ref Design for C2000 MCUs (Rev. E)).

The source code can be found in C2000Ware_MotorControl_SDK (...\C2000Ware_MotorControl_SDK_5_01_00_00\libraries\position_sensing\tformat\ccs\f2837x)
