TLC549是一个新型的AD转换器，具有8位的分辨率，具有控制简单，体积小的优点。工程当中的AD是要经过多次采集然后再计算出相对准确的值的。这里的电压值通过液晶1602显示出来。最新版本加入了软据滤波功能，软件滤波在实际工作中的AD采集是非常重要的。-TLC549 is a new type of AD converter, with a resolution of 8, has a simple control, the advantages of small size.AD which the project is to repeatedly collected and then calculate a relatively accurate value. Voltage value displayed on LCD 1602.The latest version added the soft data filtering, AD collection of software filtering in practical work is very important.
