uart通讯口的接收设计，符合大部分的uart接口协议，方便用户进行移植。-uart the receive communication port design, in line with most of the the uart interface protocol, user-transplant.

this code shows how could you change float numbers and show them on LCD. also, it shows how you could send float parameters via UART by AVR processors. It could be open by codevision 2.2 or later. see Main.AVR for recieve protocol of float parameters
