Description: 我以前曾发过V1.0版的，这是此版的修正版v1.1,修正了以前版本中的一个错误，即只能读一个数据后就再也读不出温度数据的错误。
这个是用Quartus II软件写的Verilog HDL语言写的与温湿度传感器DHT2x通信的代码. 里面有详细的注解. 主要用于DHT2x单线总线通信转换为8位并行总线通信,应用于具有外部8位总线访问功能的单片机直接读取温湿度数据. 此程序在EPM7128SLC-10中成功测试.
-I' ve once spoke V1.0 version, which is a modified version of this edition v1.1, fixes a bug in previous versions, that is no longer only after reading a data temperature data could not be read errors. This is done using Quartus II software, written in Verilog HDL language written with the temperature and humidity sensor DHT2x communications code. Which detailed footnotes. DHT2x mainly used for single-wire bus communication is converted to 8-bit parallel bus communication, used with an external 8-bit bus MCU read directly access features temperature and humidity data. EPM7128SLC-10 in this program successfully tested.
