Other Parts Discussed in Thread: C2000WARE, SYSCONFIG

Hi Team,

I have implemented GPIO interrupt [selected both edges] successfully using C2000ware example

My problem:

I want to know input level of the pin in interrupt so for that what kind of configuration or register I want to read?

also I want to route input interrupt signal level to output pin for that what I have to do in interrupt ISR?

Best regards,

So you set the input to INTERRUPT on like a rising edge. Then in the ISR you know a rising edge occured but you still want to read the current status of the pin?

Hi Nima,

Thanks for reply!

I have selected both rising and falling input level trigger interrupt in configuration so it will call ISR whenever input goes high and low.

So my question is how do I know input level in ISR?

And my second question is how to route input signal to other output pin?

Best and regards,

Raj

So specifically for reading the GPIO state, you can use the GPIO_readPin function.

Are you using C2000 SysConfig (GUI) configuration tool to configure your device? It should simplify:
