What is the best way to disable the PWM Output.

Hi Uwe,

i used the following code in irq handler to handle the 0% and 100% case.

 

...

theTIO->G0_Input_Select_Register.setG0_Source_Select( 31 ); /* Low */
theTIO->G0_Input_Select_Register.setG0_Gate_Select( 31 ); /* Low */
theTIO->G0_Input_Select_Register.setG0_Output_Polarity( pol );  /* pol=1 : 5V , pol=0 : 0V */
theTIO->G0_Input_Select_Register.flush();
theTIO->G0_Command_Register.writeG0_Disarm( 1 );

...

 

But the result ist not solid.


When you say "the result is not solid," what behavior do you observe, and what behavior do you expect? For example, when the duty cycle is 100%, perhaps the counter's output sometimes goes to the wrong output value; or perhaps it goes to the correct value but sometimes at the wrong time.

 

In the time since your post, have you learned or tried anything else about this problem?
