| Abstract: | To meet the application requirements of high-precision and high-speed,ADS7844 could be used as ADC device in embedded Linux system.This paper introduces the framework and principle of ADS7844,which is a 12-bit serial A/D converter,and analyses the circuit and linux device driver of A/D converter(ADS7844) based on ARM chip S3C2410.The implementation indicates that the driver supports A/ D conversion very well and steadily.The speed of A/D conversion by ADS7844 is extremely fast,and the precision is also very... |
