㈡ 瑞薩單片機怎樣新建一個工程
如果你用官方提供的軟體 一打開軟體介面就提示你 建 立新工程了
軟體：High-performance Embedded Workshop
㈢ 瑞薩單片機
你說的是瑞薩的哪個族的單片機，不同的族指令也不一樣的，還有個問題就是如果datasheet說明不夠詳細的話，那估計沒有比datasheet更詳細的了，給你個建議，可以去瑞薩的官網查找相關的匯編常式，看看常式中的實現方法，會對你理解指令有幫助的。還有就是想看懂指令，就要把單片機的底層了解透徹。
㈣ 瑞薩單片機的輸入捕捉功能
看R8C的技術手冊，RC作為タイマモード(インプットキャプチャ機能)時。「インプットキャプチャ入力端子選択
TRCIOA、TRCIOB、TRCIOC、TRCIOD端子のいずれか1本または復數本」（datasheet的19.4章P333）這說明是可以同時進行比較使用的，但是你想要四個通道的話就要使用「TRCCR1レジスタのCCLRビットが「0」(フリーランニング動作)」它的計數頻率就是1/fk×65536了。然後就看你的TRCIOR0和TRCIOR1對每個引腳是上沿捕捉還是下沿或者雙邊了。當然其他寄存器也是設置了。當它撲捉到引腳的信號時候TRC寄存器的值會存到相應的TRCGRi（i = A，B，C，D）寄存器，當然你不能使用它的緩沖功能了。比較倉促的回答，希望能給你些許幫助，詳細還是看看它的datasheet吧。
㈤ 2013電賽瑞薩單片機RL78G13的五路AD轉換方法
每1ms讀取一次，每次讀時，讀上一次的初始化的那一路數據，讀完後，初始化下一路。
這個單片機的AD很麻煩，定時器也不好使。還沒有真正的EEPROM。就是價位低點，ROM大點。其它真不怎麼樣。
做個電賽建議換ATMEGA吧。
㈥ 請問有哪位高手學過瑞薩單片機的，我最近接到一個小項目，需要用到瑞薩單片機，能否給我發一點資料。
瑞薩單片機也得分型號啊，我學過M16C，M32C，SH7125等，只是了解一點，你學那一款？公司用的話公司會給你們資料的！
㈦ 學會51單片機之後轉學瑞薩78K0單片機容易嗎
瑞薩78K0我沒有使用過，不過我目前正在使用瑞薩RL78系列，為解決汽車儀表方案的MCU。
根據我使用單片機的經驗，自學51單片機是肯定可以為其他系列的單片機提供幫助的。
不論學習哪種單片機，一上來就聽老師講課，沒有系統地學過大學計算機基礎、C語言、一些數電模電基礎，是肯定會雲里霧里的，何況小日本的單片機我覺得沒那麼容易上手。
我現在使用的這個系列有代碼生成器，不過沒基礎的人即使有這個東西也沒辦法真正的玩轉起來。
現在大學的課程沒以前那樣子以前那樣以傳授知識為主了，多數是任務式的，有些老師自己不懂還要糊弄學生，當然這是極個別的現象。
你盡量多花時間和精力學習51和瑞薩的，單片機都是一通百通的，弄懂了單片機的工作原理，和寄存器配置，學會查看datasheet，多去找一些官方的常式（而不是到網上隨處下載的那種，很多都不負責任地誤人子弟的東西）來琢磨。
祝你成功。
㈧ 瑞薩單片機怎麼操作eeprom
片內的還是片外的？按標准I2C時序操作就行。
㈨ 有用瑞薩單片機的大神嗎求助解決問題，我從keil移植過來的程序，之前我寫在.c和.h文件里，
查看是什麼錯誤咯，然後一個個的改。涉及到寄存器的尤其要注意。
還有就是用戶自定義的關鍵字，比如uchar，一定要把定義的地方也過來。
㈩ 誰有瑞薩rl78/g12單片機的教程或c語言代碼 急急急!
去年第一次聽說這個系列的片子，好像只有官方上有教程
