CCS/TPS92661EVM-001: LED CONTROL USING TPS92661

SRIHARSHA SANTHAPUR

Part Number: TPS92661EVM-001

Tool/software: Code Composer Studio

I am trying to control  TMS320F28035 using MATLAB/Simulink. 

I designed a  simulink model which will control the LMM SYNC, LMM CLK, LMM EN, LMM RX, LMM TX  using CCS.

But my major goal is to control the LEDs which are connected to TPS92661 .

How do i control the PWM for individual LED through MATLAB/Simulink Model?

Or should i write a custom code in CCS to control the PWM for LEDs?

If so, how to control the PWM using the TMS320F28035 ? in other way, how do TMS320F28035  control the TPS92661?

    Hi Sriharsha,

    There is a custom defined protocol that has been setup via the VCP that allows you to communicate your wishes to the 28035 via that interface (see Table 2 in the user's guide). You can leverage that for controlling from a PC. You can also send raw TPS92661 packets and the 28035 will pass those along to the LED matrix devices. This is basically like directly driving the TPS92661s from the PC.

    If your goal is to write code for the 28035 and control the LEDs locally, you'll have to use CCS and a JTAG programmer to develop your code on the hardware. The output of the MathWorks products generates compilable C code that can be used within CCS.

    I hope this helps.
