Blink LED project in F2808

Other Parts Discussed in Thread: TMS320F2808

Hello everyone,

I need to blink a LED from only one GPIO not all GPIO. So, I used the GPIO Toggle Program for available for TMS320F2808 for doing that and I could not blink the LED instead I was able to change the brightness of the LED. Please, could anyone tell me how to blink the LED. Is it possible only by Internal Clock Timer or is it possible to do that using delay_loop. TIA

Hi Bharath,

You can very well use delay loop for GPIO toggling. The reason why the brightness is changing is because of you modifying the timer value (in micro or lower msecs) which in turn is equivalent to altering the duty cycle of PWM pulse.
You need to bring down the timer value to as high as 1 sec or 500ms.
Also, I hope that you're referring to example codes from this link:
