NRF24L01Information Program(NRF24L01 Information Program)

c8051f单片机汇编语言大全,包括C51和ASM及扩展资料(C8051F ASM reference design)

说明：  这是我认为51汇编里面比较好理解的书籍，以及我简单整理的汇编指令文档一份。入门学习还是不错的。(This is a book that I think is better understood in the 51 assembly, as well as a document of assembly instructions that I simply organized. Initial study is still good.)

这是基于stm32f407的编码器程序，能够实现单片机对编码器的控制并把数据用串口发回电脑(This is the code based on stm32f407 to control encoder and return the data to pc when succeed)

说明：  自主学习PIC芯片，此书主要讲PIC16F877(Self-learning PIC chip, this book mainly talks about PIC16F877)

用于车载充电机DCDC的先进控制，包含PID控制器以及PWM控制H桥输出。(This is used for controling OBC in vehicle DCDC charging mathine, including PID control and PWM controling the output of H bridge)

利用Keil C51 和LabVIEW编写程序实现PC与单片机串口通信。 设计任务 PC通过串行口将数字（00 ，01 ，02，03... ，FF，十六进制）发送给单片机，单片机收到 后回传这个数字，PC接收到回传数据后显示出来，若发送的数据和接收到的数据相等，则串 行通信正确，否则有错误。启始符是数字00，结束符是数字 FF。(Use Keil C51 and LabVIEW programming to achieve PC serial communication with microcontroller. Displayed after the PC via the serial port design task digital (00, 01, 02,03 ..., FF, hex) is sent to the microcontroller, the microcontroller receives return this figure, PC receives the return data , if the data sent and received data are equal, the serial communication is correct, otherwise an error. Startup character is a number 00, the end of the character is a number FF.)
