TMS320F28377S: Coding CCS using MATLAB

Priya Sundaram

Part Number: TMS320F28377S


Greetings to all! I am new user of CCS and F28377S. I am doing FOC controlled PMSM drive simulation with processor in the loop. For that initially i used Embedded Coder and Simpower system tool box of MATLAB and simulated my plant and built in F28377s. And now I am aiming to code the processor using CCS. For that I thought of generating C code using Embedded coder( MATLAB) and copy the files to CCS and run. I tried LED blink example which was already available but ended up with some error issues. Can anyone please help me to do it with detailed explanation. And also I need to know whether any interfacing between MATLAB and CCS should be done before doing it? (I am using MATLAB 2017a and CCS V7) Thanks in advance.

    Hi Priya,

    You can directly load the generated executable file to the controller. I've done few video demos on Youtube.
    You can have a look at my videos here: www.youtube.com/.../UC0vWIpaMzxZ0RqT4r4Kp75w

    Hi Gautam,

    Thank you very much for the link details. Now I built the motor simulation via CCS into the processor. And I wanted to display my motor speed which is in radians per second in CRO. I sent the output through DAC to view it but I am surprised to see very small output range of value than the actual speed value. Can you explain me the cause for it?

    And also I was trying to generate a sine wave using function generator and received it through ADC into the processor. With this single sine wave as input I was aiming to get three phase sine wave which is 120 degree electrically apart. Using MATLAB I introduced 120 degree phase shift each to generate 3 phase voltage and get it through the GPIO pin. But I ended up with error message that GPIO was expecting scalar value but the one which I gave through MUX is a one dimensional 3 element vector. I wanted to know whether I am doing it in a right way. If not please do suggest me the idea to generate 3 phase sine wave.

    Thank you,

    Regards
