说明：  stm32f407zgt6液晶显示 画画 3D等功能 打电话(Stm32f407zgt6 LCD display drawing 3D and other functions)

1、修复0xfd Bug：是通过替换C51.exe和CX51.exe实现的，本补丁所提供的C51.exe和CX51.exe是使用原版的文件修改制作。对于其准确性，不做任何保证。2、添加STC单片机列表：是通过替换UV4.cdb文件和添加STC头文件实现的，本补丁所提供的UV4.cdb是根据STC官方公布的UV3.cdb文件制作。其准确性不做任何保证。3、STC的头文件（支持鼠标右键插入头文件）：头文件是从STC官网下载的，未作任何更改。头文件中虽然有STC12C54XX系列单片机的头文件4、运行程序后点击“安装程序”即可，详细说明点击“了解详情”进行查看(A repair 0xfd Bug: by replacing C51.exe and CX51.exe achieve, the patch provided C51.exe and CX51.exe is to use the original file to modify production. For its accuracy, without any guarantees. 2, add STC SCM list: Yes, and add files by replacing UV4.cdb STC header files to achieve, this patch is provided UV4.cdb UV3.cdb under STC official document production. Its accuracy is not guaranteed. 3, STC header files (support right into the header file): header files are downloaded from the official website of STC, did not make any changes. Although there STC12C54XX header file MCU header files 4, run the program and click the " Setup" button, a detailed description click on the " learn more" to view it)

STM32的I2S编程，开发板带的程序，有做I2S音频这块的同学可以看看(STM32 I2S programming, development board with the program, has done I2S audio piece classmates can look)

这是一个实现AVR单片机的SPI应用示例程序(This is a realization of AVR MCU SPI application sample programs)

实现简单的RS232 TO CAN,CAN T0 RS232的数据转换 (Realize a simple RS232 TO CAN, CAN T0 RS232 data conversion)

说明：  pcf8591 AD转换程序，可以实现电压表功能，四路模拟输入，一路输出DA输出。(pcf8591 AD conversion process, you can achieve the voltmeter function, four analog inputs, one output DA output.)

使用SSD1306或者SH1106驱动芯片的OLED程序初始化代码。(OLED init for the driver chip SSD1306 or SH1106.)

说明：  基于WiFi的温湿度监测与显示，(1)主控芯片采用STM32系列单片机、数字温湿度度传感器DHT11、WiFi模块ATK-ESP8266； (2)通过数字温湿度度传感器DHT11采集数据； (3)将数据通过WiFi模块在电脑上进行显示。(Temperature and humidity acquisition)

说明：  能够完成板球题目，2017年全国大学生电子设计大赛国赛题，具体内容详见文件(can analyse the movement of the ball on the platform.)

这是一个基于C51的软件模拟串口程序，希望对大家有用。(This is a C51-based simulation software serial procedures in the hope that useful.)
