CC2640R2L 无32K晶振初始化ADC失败

Other Parts Discussed in Thread: CC2640R2F

您好！

将工程从2640R2F移植到2640R2L，CCS版本V9.0.1.00004,没有换到最新的CCS，工程的设备还是选的CC2640R2F，目前移植后蓝牙连接，PWM,UART,GPIO中断等都没问题，就是ADC移植后无法使用，后面使用例程的顺序初始话，ADC_open这一步失败，贴出代码如下：

if(user_ADC_Handle[ADC_Channel] == NULL)   //static ADC_Handle user_ADC_Handle[USER_ADCCOUNT];
	{
	    ADC_init();
	   ADC_Params_init(&user_ADC_Params[ADC_Channel]);  //static ADC_Params user_ADC_Params[USER_ADCCOUNT];
	   user_ADC_Params[ADC_Channel].isProtected= true;
	   user_ADC_Handle[ADC_Channel]=ADC_open(0,&user_ADC_Params[ADC_Channel]);
	   if(user_ADC_Handle[ADC_Channel] == NULL)
	   {
	       while(1);
	   }
        }
没有搞懂IO映射，直接ADC_open第一个参数填的0.最后程序进入了while(1).请帮忙分析下可能是哪儿的问题，谢谢你！

看下ADC_Config里的设置

const ADC_Config ADC_config[CC2640R2_LAUNCHXL_ADCCOUNT] = {
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC0], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC0]},
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC1], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC1]},
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC2], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC2]},

    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC6], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC6]},
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADC7], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADC7]},
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADCDCOUPL], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADCDCOUPL]},
    {&ADCCC26XX_fxnTable, &adcCC26xxObjects[CC2640R2_LAUNCHXL_ADCVSS], &adcCC26xxHWAttrs[CC2640R2_LAUNCHXL_ADCVSS]},

};
const ADCCC26XX_HWAttrs userADCHwAttrs[USER_ADCCOUNT] = {
{
//ADC0的配置
.adcDIO = ADC_PIN0,//#define ADC_PIN0 IOID_12
.adcCompBInput = ADC_COMPB_IN_AUXIO7,
.refSource = ADCCC26XX_FIXED_REFERENCE,
.samplingDuration = ADCCC26XX_SAMPLING_DURATION_2P7_US,
.inputScalingEnabled = false,
.triggerSource = ADCCC26XX_TRIGGER_MANUAL,
.returnAdjustedVal = 0
},
因为之前2640R2F有比较器，而2640R2L没有， .inputScalingEnabled由true改为false了,在2640R2L上跑不过，RHB封装DIO7-DIO14可以作为模拟引脚。

能看下图中adcCC26XXHWAttrs的初始化吗，基于2640R2L的

参考software-dl.ti.com/.../_a_d_c_buf_c_c26_x_x_8h.html解决。
一个ADC映射表
It maps a DIO to its corresponding driverlib define for the CompBInput that it is hardwired to. This table can be used to create virtual channel entries in the ADCBufCC26XX_adcChannelLut table in the board file.

已经解决了吗？是引脚映射问题？
