瑞萨单片机入门 [复制链接]

新入职一家芯片代理公司做fae，这两天给了我一个R5F10268的板子然后给了个例子叫我熟悉一下，但是C语言和单片机的只是掌握的一般，现在看着这个程序完全没有头绪，公司老的工程师又都在外面没人能教，有坛友帮我解释下这个程序的功能吗？

建议把程序嵌入到帖子内显示
然后就是把不懂的地方说明一下，大家可以更好帮助你

单条的命令基本能看懂，但是比如main函数实现了什么功能就有点懵了

看你好像调用了FDLRL78 Type04库里面的函数，这是一个flash模拟eeprom的库，具体的可以看资料
这个是瑞萨官方的资料

这 ...

恩恩，十分感谢，我当时是想知道具体单个函数的讲解，我先看看资料吧

调用Type04 的库，对数据闪存的读写等一些操作，单个函数功能在库中对应的地方有注释~

你公司也是扯JB蛋，既然让你看这个，说明文档肯定要提供的吗，何况这本来也是瑞萨官网下来
