关于23D+DSP无法进行ADC校准

Battery Slope=-7157174 ADC offset=-1890728448
,Charger Slope=-25063768 ADC offset=1731147776
Check Battey Channel Slop Failed
Check Battery Channel Offset Failed
ADC Calibration current difference Failed
ADC Calibration voltage difference 8590.341797 Failed
ADC Calibration time=3.000000
Actually measurement time=26096.000000
GSM/EDGE Cal Total Time = 47.09(sec)

检测电压 电流的ADC channel 选对没有?

是否和DSP部分有关?

与DSP应该没有关系，adc channel选了6 5后ADC SLOPE校准PASS了，后来出现METAPP_TIMEOUT 222不知道是什么问题

请问"adc channel选了6 5"这是什么意思?能否详细说下

CFG文件里面修改
[ADC table]
ADC_V1 = 3400
ADC_V2 = 4200
NORMAL_VOLTAGE = 3800
CURRENT_LIMIT = 2000
MAX_BATTERY_ADC_SLOPE = 5550.0
MIN_BATTERY_ADC_SLOPE = 5250.0
MAX_BATTERY_ADC_OFFSET = 1000000
MIN_BATTERY_ADC_OFFSET = -1000000
BATTERY_CHANNEL = 6
CHARGER_CHANNEL = 5
ADC_RESISTANCE = 0.39
MAX_VOLTAGE_DIFFERENCE = 0.04
MAX_CURRENT_DIFFERENCE = 0.04
ADC_MEASUREMENT_COUNT = 1000

关注中，我也正遇到MATE TIMEOUT 问题，目前也还在找原因。
至于小编的问题，DATA SHEET上面关于ADC CHANNEL的作用有讲到，电池和充电在23D是用的6和5CHANNEL,25上则用的0和1CHANNEL

ADC_RESISTANCE = 0.39
应该更改为ADC_RESISTANCE = 0.22的吧，具体需要看你使用的电阻数值

楼上提出的这个值有修改过，但问题依旧，除了这两个参数还有其他地方吗?

修改完设置后，如果还不行，就要确认一下，板子有没有漏电，如果有漏电，也会影响。

谢谢楼上的，问题已经解决，软件问题，硬件只要把CHANNEL改对就OK了

ADC配置如下：
const unsigned char ADC_ACCESSORYID = 2;
const unsigned char ADC_VCHARGER = 4;
const unsigned char ADC_VISENSE = 5;
const unsigned char ADC_VBAT = 6;
const unsigned char ADC_VBATTMP = ADC_ERR_CHANNEL_NO;
const unsigned char ADC_PCBTMP = ADC_ERR_CHANNEL_NO;
const unsigned char ADC_CHR_USB = ADC_ERR_CHANNEL_NO;
const unsigned char ADC_OTG_VBUS = ADC_ERR_CHANNEL_NO;
ATE校准出数据如下：
===================== Begin Calibration =========================
Battery Slope=427823 ADC offset=-4640885

已解决
原因是CONFIG里BATTERY_CHANNEL与CHARGER_CHANNEL配置错误。

学习了.

谢谢！学习

我也遇见同样的问题，现在已经解决谢谢小编
