Hi everyone,
I try to vary the frequency of the PWM signals(which use for three phase inverter) by chanching the frequency of the input sine wave.In simulink model i can get the frequency variation with changing frequency of sine wave by using knob.
But when i tried in external model in c2000 F28379D launchpad and connected signals to osciloscope,there was not any variation of pwm frequency with changing the sine wave frequency and Following eror shows,
Error occurred while executing External Mode MEX-file 'ext_comm':
ExtTargetPktPending() call failed while checking for target pkt
Component:Simulink | Category:Block diagram error
Error occurred while executing External Mode MEX-file 'ext_comm':
ExtSetTargetPkt() call failed on CLOSE.
Ensure target is still running
this is my MATHLAB Simulink model,aa.JPG
Venkatesh Chilapur do you have any suggession for this,
Thank you in Advance,

hello
have you find the solution ?
I would like to inquire about sine wave block in external mode to implement my model in hardware side, is there any setting that must I do ?
