Custom code changes- I/O pin go high or low

Hi,
Can I set a pin to go high under a certain condition for example: when the battery is lower than a certain value, can I make one of the pins to go high or low? and if so how can I make that happen?

You could have checked the vesc code and found examples or read ChibiOS but that's one way to do it:           

 if (condition)  {
                                palSetPad(GPIOx, x); or

                               palClearPad(GPIOx, x);

}

Hi Vadicus,

 

I am thinking of using the RX pin out and I checked it on the Sch it shows as GPIOB 11. 

So if does the following makes sense?

 if (condition)  {
                                palSetPad(GPIOB_Pin 15, 15)

} ?
