项目功能目标:使用单片机和8×8点阵LED模块构建一个广告牌。在广告牌上滚动显示“I LOVE MCU”(我爱单片机)的字样。同学们首先要掌握8×8点阵LED动态显示的工作原理,结合8×8点阵LED电路原理图进行驱动代码的编写,当遇到困难时再参照本例中的源代码。特别提醒:同学们千万不要以为自己代码看懂了,就算万事大吉了。其实不然,刚开始学习时,一定要将源代码一条一条地写入KEIL软件中,一边写一
Project Objectives: Using a single-chip and 8 × 8 dot matrix LED module to build a billboard. Scroll the billboard to display “I LOVE MCU”. Students must first master the working principle of 8 × 8 dot matrix LED dynamic display, combined with the schematic diagram of 8 × 8 dot-matrix LED circuit driver code preparation, refer to the source code in this case when encountering difficulties. Reminded: students do not think they understand the code, even if everything is fine. In actual fact, just started learning, we must write the source code one by one KEIL software, while writing a
