Other Parts Discussed in Thread: TMS320F28069M
Tool/software: TI C/C++ Compiler
Hi,
I’m using BOOSTXL-3phGaNInV board with TMS320F28069M Launchpad. I’m programming the setup using CCS v6 and MATLAB 2017a (including all the support packages). I’ve made a simple model, to provide PWM signals (using ePWM) to the inverter board. I’m using headers J5/J7 and J6/J8. Also, GPIO52 to enable PWM (active low). I can see the PWM signals being received to the board, by examining Header pins J2 on the inverter board. My problem is, when I measure the voltage on the input DC terminals (header J4) , I see a voltage of around 3 V ( no source connected). How can I solve this problem?
Also, I’m programming the MCU to run from “Flash Mode”, but it seems every time I disconnect the setup, I had to build the model again. Is this Normal ?
P.S. My model is very simple, just testing if the setup runs.
Image of the setup is also attached.
Thanks in advance.
