基于51单片机的2G以下SD卡电子相册程序

通过读出SD卡中320x240像素、16位BMP图片的HEX数据，依次写到屏上，还原图片

注意事项：由于SD卡使用SPI模式，并且是块读取(512Byte),所以需要单片机提供大于512的可用RAM，以供缓冲使用这里可以选择STC89c52RD+、STC89C58RD+、STC89C516RD+，后缀RD+表明扩展RAM是1024字节，RC表明扩展RAM256字节-Based on 51 single-chip electronic album 2G SD card the following procedure by reading the SD card 320x240 pixels, 16-bit BMP images HEX data sequentially written to screen, restore the picture Note: Due to the SD card using SPI mode, and is a block read Take (512Byte), so it is necessary to provide more than 512 microcontrollers available RAM, for buffering uses where you can select STC89c52RD+, STC89C58RD+, STC89C516RD+, suffix RD+ show expanded RAM is 1024 bytes, RC indicates expansion RAM256 bytes
