This chapter describes the functions and usage of ADC & Touch Screen interface S3C6410X RISC
microprocessor.
39.1 OVERVIEW
The 10-bit/12-bit CMOS ADC (Analog to Digital Converter) is a recycling type device with 8-channel analog
inputs. It converts the analog input signal into 10-bit/12-bit binary digital codes at a maximum conversion rate of
1MSPS with 5MHz A/D converter clock. A/D converter operates with on-chip sample-and-hold function. The
power down mode is supported.
八路,满足你的要求吗?嘿嘿。
8路不够 起码24路 而且4路触摸屏要用掉 我打算用CD4067B了 这样其实驱动程序也不复杂啊
