zigbee协议栈里怎么使用cc2530adc？

你可能还没有使能IO的ADC功能，设置APCFG寄存器。

参考这边的详细配置： http://blog.csdn.net/qq_15647227/article/details/53393253

额，我去试试

感谢!

调用了下面的函数后还要配置那些东西才行啊？

uint16 HalAdcRead (uint8 channel, uint8 resolution)
{
int16 reading = 0;

#if (HAL_ADC == TRUE)
uint8 i, resbits;
uint8 adcChannel = 1;

/*
* If Analog input channel is AIN0..AIN7, make sure corresponing P0 I/O pin is enabled. The code
* does NOT disable the pin at the end of this function. I think it is better to leave the pin
* enabled because the results will be more accurate. Because of the inherent capacitance on the
* pin, it takes time for the voltage on the pin to charge up to its steady-state level. If
* HalAdcRead() has to turn on the pin for every conversion, the results may show a lower voltage
* than actuality because the pin did not have time to fully charge.
*/
if (channel < 8)
{
for (i=0; i < channel; i++)
{
adcChannel <<= 1;
}
}

/* Enable channel */
ADCCFG |= adcChannel;

/* Convert resolution to decimation rate */
switch (resolution)
{
case HAL_ADC_RESOLUTION_8:
resbits = HAL_ADC_DEC_064;

resbits = HAL_ADC_DEC_256;
break;

resbits = HAL_ADC_DEC_512;
break;
}

/* writing to this register starts the extra conversion */
ADCCON3 = channel | resbits | adcRef;

/* Wait for the conversion to be done */
while (!(ADCCON1 & HAL_ADC_EOC));

/* Disable channel after done conversion */
ADCCFG &= (adcChannel ^ 0xFF);

/* Read the result */
reading = (int16) (ADCL);
reading |= (int16) (ADCH << 8);

/* Treat small negative as 0 */
if (reading < 0)
reading = 0;

switch (resolution)
{
case HAL_ADC_RESOLUTION_8:
reading >>= 8;
break;
case HAL_ADC_RESOLUTION_10:
reading >>= 6;
