Config GPIO / ADC for CC2530 GenericApp

Hi everyone,

1) I configured pin P0_6 and P0_7 as below

P0SEL &=(~BV(6));
P0DIR |= BV(6);

P0SEL &=(~BV(7));
P0DIR |= BV(7);

It's working OK but sometime I set P0_6 = 1 but It's still 0 ( I measured by VOM)

How can I check the ouput P0_6 after set to 1?

2) Besides, I used P0_5 as ADC input.

Set HAL_ADC=TRUE in Preprocessor and

HalAdcSetReference(HAL_ADC_REF_125V);

adc_ain5=HalAdcRead(HAL_ADC_CHN_AIN5,HAL_ADC_RESOLUTION_12);

The problem is the output of P0_5 ~ 3.2V. And the measured value is not correct. Any config is wrong?

Thanks in advance.

1. You can set a breakpoint after you set it and check register value in IAR debug.
2. You can refer to sunmaysky.blogspot.tw/.../cc2530-adc-howto-in-ti-z-stack.html for ADC reading.

Thank for prompt reply ,
1) Can you show me check it by code?
2) Sorry for making you confusing.
Actually I want to read ADC value in P0_5. But pin P0_5 always output about 3.2 V. And read value is not correct. I don't know pin should be configured or not?

1. You can use "if(P0_6==1){...}else{...}"
2. You should check if P0.5 is configured elsewhere in your code.

1) Thank you. I will try it.
2) I'm using GenericApp, didnt't configure P0_5. My config of (1) affected on it?

2. Your codes in (1) won't affect P0.5.
