UltrasonicTesting

基于STM32F103的文件管理系统。移植了FATFS文件系统，从SD卡中读取JPEG与bmp格试图片，然后显示。并带有触摸功能(The file management system based on STM32F103.Transplant FATFS file system, the SD card read JPEG and BMP test images, and then display.And with touch function)

单片机驱动的OLED显示屏，单色绿光。C语言(Single-chip-driven OLED display, monochrome green. C language)

通过对原始图像的水平和垂直投影图像来对车牌进行水平方向的定位(Original image through the level and vertical projection of images to the horizontal direction of the plate for the positioning of)

该驱动程序库包含了I2C总线基本时序以及AT24C系列EEPROM的读写函数.还包含了常用数据格式变量的保存、读取函数。除了字节读写之外，还可以很方便的向EEPROM里写入和读出整型、浮点数、长整型格式的数据。(The driver library includes the basic timing of the I2C bus and EEPROM read and write functions AT24C series. Also includes a common data format for the variable save, reading function. In addition to reading and writing bytes, but also can easily write and read to the EEPROM in the integer, floating point, long integer format.)
