TMS32F28337S

28377S中ADCIN14和ADC15引脚怎样使用？我想配置ADCIN14和ADCIN15为差分输入，16bit

HG：

Analog Subsystem

–Up to Four Analog-to-Digital Converters (ADCs)

– 16-Bit Mode

– 1.1 MSPS Each (up to 4.4-MSPS System Throughput)

– Differential Inputs

– Up to 12 External Channels

tms320f28377s.pdf 数据手册中有说明。你可以参考ccs里面的示例代码。

ADCIN14  Input 14 to all ADCs. This pin can be used as a generalpurpose ADCIN pin or it can be used to calibrate all ADCs together (either single-ended or differential) from an external reference.

CMPIN4P I Comparator 4 positive input

ADCIN15  Input 15 to all ADCs. This pin can be used as a generalpurpose ADCIN pin or it can be used to calibrate all ADCs together (either single-ended or differential) from an external reference.

CMPIN4N I Comparator 4 negative input
