Hello,

I want to assign some variable to GPIO pin to check the signal but I am not able to that. I am using the following method

GpioDataRegs.GPADAT.bit.GPIO20=&Thetta;

Please, guide me how to assign variable to any GPIO pin. I am getting the error that value to type double cannot be assigned to an entity of type Uint16.

Thanks you.

Hi,

You can simply assign as:

GpioDataRegs.GPADAT.bit.GPIO20=Thetta; //where Thetta can be 0 or 1

Gautam

Dear Gautam,
Thanks for your response.

Actually i want to assign variable signal to GPIO and it is varrying continuosly not between 0 and 1 like sinusoidal signal. Is this possible?

Nope, that doesn't make sense. GPIO an either be logic 0 or 1. What you seem to be looking for is generating SPWM signal, which when passed through a filter would give you a Sine signal. Am I right?
