一个测试过的非常好用的CAN 的多级通讯的实例(A test had been very useful multi-level communication CAN example)

说明：  STM32F407驱动SPI屏幕，采用的是模拟SPI(STM32F407 drives SPI screen, using simulated SPI)

A， 单发单收，在发送状态，能够连续发送从0到99的数字； B， 单发单收，在接收状态，能够接收数据，并在数码管上正确地显示出来； C， 单发多收，在AB完成的基础上，接上多个接收设备，能够正确发送和接收 这是从站2的代码(A, single-input single in the sending state, capable of continuously transmitting a number from 0 to 99 B, single-input single in the receiving state, capable of receiving data, and display correctly in the digital tube out C, single overcharged, on the basis of AB completed, connect multiple receiving devices, capable of sending and receiving the correct code from the station which is 2)

通过小键盘的输入来控制输出的演示 设计要求：按下“A”键时，在七段数码管各位上循环显示“8”；按下“B”键时，在发光二极管上绿色、黄色、红色灯管依次循环定时点亮；按下“C”键时，退出，在七段数码管上显示“P”。 (Through the keyboard input to control the output of the demonstration)

第8届飞思卡尔摄像头组设计方案，详细的介绍了如何处理图像、识别赛道等问题。(8th Freescale camera group design, describes in detail how to handle images, identify the track and other issues.)

基于51单片机通信的其中一种，I2C总线通信。(I2C bus communication is one of 51 MCU communication.)

AT45DB081D 说明文档,网上很难找到哦(AT45DB081D datasheet)

七段数码管的显示驱动程序.分查表法和跳转法.采用松翰8位单片机汇编语言编写的子程序, 本人验证过.(seven_segment_tube_display.asm assembly with Sonix 8bit IC)

了解SINAD、ENOB、SNR、THD、THD + N、SFDR，不在噪底中迷失。用于定量表示ADC动态性能的常用指标有六个，分别是：SINAD(信纳比)、ENOB(有效位 数)、SNR(信噪比)、THD(总谐波失真)、THD + N(总谐波失真加噪声)和SFDR(无杂散动态 范围)。(Learn SINAD, ENOB, SNR, THD, THD+ N, SFDR, lost not noise floor. For quantitative expression commonly used indicators of the dynamic performance of the ADC six are: SINAD (SINAD), ENOB (effective number of bits) and SNR (signal-to-noise ratio), THD (total harmonic distortion), THD+ N ( The total harmonic distortion plus noise) and SFDR (spurious-free dynamic range).)
