开发环境是Silab，里面有两个代码，实现的功能是两单片机C8051F040的CAN通信，发送程度先将浮点数3.14159和长整型数1234567L转换成MSGNUMD号消息数据。发送给接收端。接收端将接收到的数据重新转换成浮点数和长整型数。-Development environment is Silab, it there are two codes, to achieve the function of two of the CAN microcontroller C8051F040 co

单片机在通信中，浮点数的处理往往容易出错，本代码解决单片机通信时的浮点数据转换处理，包括浮点数转换成char ,和char转成float类型(The processing of floating point data is often prone to make mistakes in the communication of single chip microcomputer. This code solves the floating point data conversion proces
