Other Parts Discussed in Thread: CC2510

Hi,

I'm using cc2510.

If I configure a GPIO as an output pin and then write something like P2_0 = 1;

If I will now try to read the pin value will I read the last value I wrote to it?

Thanks

If you mean will reading the port register return the current value of the outputs, then yes, it will.

Hi,

I have a cc2430dk and I have to modify the pin definition for programing my board with a different Hal. The configuration of the leds and the buttons are in the hal_board_cfg.h.

My question is in wish .h or .c there are the configuration of the adc, potentiometer...

tks

The mapping to the ADC channels is done in ZStack-1.4.3-1.2.1\Components\hal\target\CC2430EB\hal_key.c. The only term I found that uses the ADC is for the joystick and initially the potentiometer when creating an address.

The hal_adc.c file implements the various read functions of the ADC.
