This program with source code to convert ascii text files to the maxicode barcode standard. The input file consists of two columns. The first column represents a code and the second column is a string enclosed in quotes. The codes for the first column are as follows: PM, SM, CC, MO, SC, and PC. - This is program with source code to convert ascii text files to the maxicode barcode standard.

BK2411资料难找，BK2411使用起来跟24L01基本一样，硬件上基本兼容，软件上只是开始要对BK2存储器进行初始化，花掉很长一段代码。初始化完成后，操作就跟24L01基本一样了-BK2411 information hard to find, BK2411 to use essentially the same with the 24L01, the hardware basically compatible, software is only the beginning of the BK2 memory to initialize, to spend a very long piece of code. Initialization is complete, operate basically the same as the Jiugen 24L01

应用背景在STM32F105和STM32F107互连型系列微控制器之前，意法半导体已经推出STM32基本型系列、增强型系列、USB基本型系列、互补型系列；新系列产品沿用增强型系列的72MHz处理频率。内存包括64KB到256KB闪存和 20KB到64KB嵌入式SRAM。新系列采用LQFP64、LQFP100和LFBGA100三种封装，不同的封装保持引脚排列一致性，结合STM32平台的设计理念，开发人员通过选择产品可重新优化功能、存储器、性能和引脚数量，以最小的硬件变化来满足个性化的应用需求。关键技术本实验将实现如下功能：开机先检测字库是否存在，如果检测无问题，则对VS1053进行RAM测试和正弦测试，测试完后开始循环播放SD卡MUSIC文件夹里面的歌曲（必须在SD卡
