思睿逻辑 EP93xx 模拟数字转换器驱动 |
|
================================== |
|
|
|
1. 概述 |
|
======= |
|
|
|
该驱动同时适用于具有5通道模拟数字转换器的低端 (EP9301, Ep9302) 设备和10通道 |
|
触摸屏/模拟数字转换器的高端设备(EP9307, EP9312, EP9315)。 |
|
|
|
2. 通道编号 |
|
=========== |
|
|
|
EP9301和EP9302数据表定义了通道0..4的编号方案。虽然EP9307, EP9312和EP9315多 |
|
了3个通道（一共8个），但是编号并没有定义。所以说最后三个通道是随机编号的。 |
