CCS/TMS320F28335: How to use TMS320F28335 connect to Digital temperature Controller(RB900) ?

Part Number: TMS320F28335

Tool/software: Code Composer Studio

1. How to use TMS320F28335's command sent signal to Digital temperature Controller(RB900) through RS485?

EX：sent  {0x01, 0x03, 0x00, 0x00, 0x00, 0x01, 0x84, 0x0A} , and we want grab this matrix one of the numbers

2.Could SCI module command build with ePWM module command ? 

EX:We want to RX temperature  to change frequency  then change wave.

3.could we use TMS320F28335 connect C#?

    Bo-Xiang,

    The F28335 is compatible with RS-232 type communications.  When connecting to an external communications device, you need to make sure that the format and baud rate match.  If it does not match you may receive unexpected data.  If I understand you correctly, you would like to read data (temperature) from an external device using the SCI and then modulate an ePWM module.  You would need to program the device to do this, and it is typically done in the interrupt service routine (ISR).  I am not sure what you mean with question 3, but CCS compiler supports C/C++.

    I hope this helps. If this answers your question, please click the green "Verified Answer" button. Thanks.
