Configure a line to trigger a relay

haroldvogel — Tue, 19 Apr 2016 19:18:02 GMT

I hope that someone can walk me through on using Processor Expert to configure a line (PTC17 on the MKL36Z256VLL4). This line would be set for a period of time (120ms to 59 seconds) and then turned off after the time period has expired.

Hello Harold,

You can use component "BitIO" and "TimerInt_LDD" of PE.

- After add BitIO , configure it , select the port of PTC17, and Direction is Output:

- Refer to your demand configure the timer , in the timer interrupt toggle the PTC17:

About the detail usage of these component , please refer to help on component -> Typical Usage, there is demo code :

When you create , if encounter some question , you can contact me without any hesitate.

Hope it helps

Have a great day,
Alice

Hello Alice,

What is the difference between using the BitIO and the GPIO_LDD?

Hello Harold,

The BitIo component implements an one-bit input/output. It uses one bit/pin of an I/O port.

The GPIO_LDD component is a gpio driver, it can configure gpio interrupt .

IF you only want output high or low ， both them are ok.

For the detail you can refer to the "help on component " to check .

Hope it helps
