text-align-type-left pap-line-1.3 pap-line-rule-auto pap-spacing-before-3pt pap-spacing-after-3pt" style="line-height:1.8;">        这次制作虽然不是很好，第一次焊接时芯片没有焊坏，导致芯片无法工作，程序烧录不了。第二次焊接成功，但是数码管上的数字不能正常显示，经查找，发现芯片有一个引脚没焊接到。在这次项目制作时主要问题时由于我的焊接技术不够，导致在制作过程中出现多种问题，但经过这次项目我学会了基于瑞萨的程序改写，焊接技术也有了进一步的提高。非常感谢立创以及瑞萨等为我提供学习的机会，也希望以后可以参加更多立创项目。</p> <p
