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