CC2640R2F ADC问题-TI中文支持网

有大神指导一下吗?

现在我在用CC2640R2F的ADC功能是参考ti例程adcsinglechannel做的。但是我发现我一旦调用ADC_init();函数我所有的按键中断全部失灵。而且ADC功能也不正常。

以下是我的配置：

引用的头文件如下：

#include <ti/drivers/ADC.h>

#include <ti/drivers/adc/ADCCC26XX.h>

配置文件如下：

/* Analog Capable DIOs */
#define CC2640R2_LAUNCHXL_DIO5_ANALOG          IOID_5
#define CC2640R2_ADCCOUNT   1
typedef enum CC2640R2_LAUNCHXL_ADCName {
    CC2640R2_LAUNCHXL_ADC0 = 0,
    CC2640R2_LAUNCHXL_ADC1,
    CC2640R2_LAUNCHXL_ADC2,
    CC2640R2_LAUNCHXL_ADC3,
    CC2640R2_LAUNCHXL_ADC4,
    CC2640R2_LAUNCHXL_ADC5,
    CC2640R2_LAUNCHXL_ADC6,
    CC2640R2_LAUNCHXL_ADC7,
    CC2640R2_LAUNCHXL_ADCDCOUPL,
    CC2640R2_LAUNCHXL_ADCVSS,
    CC2640R2_LAUNCHXL_ADCVDDS,
    CC2640R2_LAUNCHXL_ADCCOUNT
} CC2640R2_LAUNCHXL_ADCName;

ADCCC26XX_Object adcCC26xxObjects[CC2640R2_ADCCOUNT];
const ADCCC26XX_HWAttrs adcCC26xxHWAttrs[CC2640R2_ADCCOUNT] = {
    {
        .adcDIO              = CC2640R2_LAUNCHXL_DIO5_ANALOG,
        .adcCompBInput       = ADC_COMPB_IN_AUXIO5,
        .refSource           = ADCCC26XX_FIXED_REFERENCE,
        .samplingDuration    = ADCCC26XX_SAMPLING_DURATION_2P7_US,
        .inputScalingEnabled = true,
        .triggerSource       = ADCCC26XX_TRIGGER_MANUAL,
        .returnAdjustedVal   = false
    }
};

//ADC
const ADC_Config ADC_config[CC2640R2_ADCCOUNT] = {
{&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC5], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC5]},
};
//ADC_COMPB_IN_AUXIO5
const uint_least8_t ADC_count = CC2640R2_ADCCOUNT;

其他什么都不做，然后我在初始化函数那里加上 ADC_init();就出问题了。请问我哪个地方配置出错了？

有能够正常跑起来的ADC例子可以给我参考一下吗？

Susan Yang：

请问您按键是用的哪些管脚？是否和ADC的引脚有冲突？

Jasmine Wang：

回复 Susan Yang:

我使用的按键IO口是DIO7和IOD6，ADC检测口是DIO5,没有冲突。 Susan有建议吗?

Alvin Chen：

回复 Jasmine Wang:

void *threadFxn0(void *arg0)
{ADC_Handleadc;ADC_Paramsparams;int_fast16_t res;ADC_Params_init(&params);adc = ADC_open(Board_ADC0, &params);if (adc == NULL) {Display_printf(display, 0, 0, "Error initializing ADC channel 0\n");while (1);}/* Blocking mode conversion */res = ADC_convert(adc, &adcValue0);if (res == ADC_STATUS_SUCCESS) {adcValue0MicroVolt = ADC_convertRawToMicroVolts(adc, adcValue0);Display_printf(display, 0, 0, "ADC channel 0 convert result: %d uV\n", adcValue0MicroVolt);}else {Display_printf(display, 0, 0, "ADC channel 0 convert failed\n");}ADC_close(adc);return (NULL);
}

你参照这个用ADC_OPEN配置ADC即可，无需使用ADC_INIT。此外如果你要用按键操作推荐使用以下code：

你的芯片是7*7的封装不?

Dear Alvin:

我参考网上的例程已经可以检测到AD值了，但是我发现它的AD基准电压是4.3V，我想要将电源电压作为参考电压，请问要怎么设置？
