㈡ 瑞萨单片机怎样新建一个工程
如果你用官方提供的软件 一打开软件接口就提示你 建 立新工程了
软件：High-performance Embedded Workshop
㈢ 瑞萨单片机
你说的是瑞萨的哪个族的单片机，不同的族指令也不一样的，还有个问题就是如果datasheet说明不够详细的话，那估计没有比datasheet更详细的了，给你个建议，可以去瑞萨的官网查找相关的汇编例程，看看例程中的实现方法，会对你理解指令有帮助的。还有就是想看懂指令，就要把单片机的底层了解透彻。
㈣ 瑞萨单片机的输入捕捉功能
看R8C的技术手册，RC作为タイマモード(インプットキャプチャ机能)时。“インプットキャプチャ入力端子选択
TRCIOA、TRCIOB、TRCIOC、TRCIOD端子のいずれか1本または复数本”（datasheet的19.4章P333）这说明是可以同时进行比较使用的，但是你想要四个通道的话就要使用“TRCCR1レジスタのCCLRビットが“0”(フリーランニング动作)”它的计数频率就是1/fk×65536了。然后就看你的TRCIOR0和TRCIOR1对每个引脚是上沿捕捉还是下沿或者双边了。当然其他寄存器也是设置了。当它扑捉到引脚的信号时候TRC寄存器的值会存到相应的TRCGRi（i = A，B，C，D）寄存器，当然你不能使用它的缓冲功能了。比较仓促的回答，希望能给你些许帮助，详细还是看看它的datasheet吧。
㈤ 2013电赛瑞萨单片机RL78G13的五路AD转换方法
每1ms读取一次，每次读时，读上一次的初始化的那一路数据，读完后，初始化下一路。
这个单片机的AD很麻烦，定时器也不好使。还没有真正的EEPROM。就是价位低点，ROM大点。其它真不怎么样。
做个电赛建议换ATMEGA吧。
㈥ 请问有哪位高手学过瑞萨单片机的，我最近接到一个小项目，需要用到瑞萨单片机，能否给我发一点资料。
瑞萨单片机也得分型号啊，我学过M16C，M32C，SH7125等，只是了解一点，你学那一款？公司用的话公司会给你们资料的！
㈦ 学会51单片机之后转学瑞萨78K0单片机容易吗
瑞萨78K0我没有使用过，不过我目前正在使用瑞萨RL78系列，为解决汽车仪表方案的MCU。
根据我使用单片机的经验，自学51单片机是肯定可以为其他系列的单片机提供帮助的。
不论学习哪种单片机，一上来就听老师讲课，没有系统地学过大学计算机基础、C语言、一些数电模电基础，是肯定会云里雾里的，何况小日本的单片机我觉得没那么容易上手。
我现在使用的这个系列有代码生成器，不过没基础的人即使有这个东西也没办法真正的玩转起来。
现在大学的课程没以前那样子以前那样以传授知识为主了，多数是任务式的，有些老师自己不懂还要糊弄学生，当然这是极个别的现象。
你尽量多花时间和精力学习51和瑞萨的，单片机都是一通百通的，弄懂了单片机的工作原理，和寄存器配置，学会查看datasheet，多去找一些官方的例程（而不是到网上随处下载的那种，很多都不负责任地误人子弟的东西）来琢磨。
祝你成功。
㈧ 瑞萨单片机怎么操作eeprom
片内的还是片外的？按标准I2C时序操作就行。
㈨ 有用瑞萨单片机的大神吗求助解决问题，我从keil移植过来的程序，之前我写在.c和.h文件里，
查看是什么错误咯，然后一个个的改。涉及到寄存器的尤其要注意。
还有就是用户自定义的关键字，比如uchar，一定要把定义的地方也过来。
㈩ 谁有瑞萨rl78/g12单片机的教程或c语言代码 急急急!
去年第一次听说这个系列的片子，好像只有官方上有教程
