瑞萨H8_3048单片机资源

16位集成定时器H8_3048系类单片机内还有一个16位的集成定时单元ITU,有五个16位定时通道0到4。

1.结构与特点1.1内部结构每个通道还有三个16为寄存器：定时计数器TCNT，通用寄存器GRA 和GRB;四个8为寄存器：定时控制寄存器TCR，定时I/O控制寄存器TIOR,定时中断允许寄存器TIER和定时状态寄存器TSR.ITU有TCLKA到TCLKD等四个外部时钟输入，以及四种频率的内部时钟输入。

可以从这八个时钟源中选定一个座位通道定时计数器TCNT 的计数源。

TCNT可以产生计数溢出中断，与通用寄存器GRA或GRB 比较中断，捕捉到有效信号时TCNT 值传给GRA或GRB,也可同时请求IMIA或IMIB中断。

通道3和通道4还多了两个寄存器BRA和BRB,它们是16位的缓冲寄存器。

通道4还多了两条输出比较引脚——TOCXA4和TOCXB4.1.2 ITU的特点1)可以处理多达12个脉冲输出或10个脉冲输入；2)10个通用寄存器可单独赋予输出比较或输入捕获功能；3)每个通道均可从8个时钟源中任选一个；4)5个通道中，对每个都有5种运作方式可供选择。

1.3 输入输出引脚（这里只说明工作在PWM方式下）通道0到通道2都有两个输入/输出引脚通道0 TIOCA0 GRA0输出比较或输入捕捉引脚，PWM方式下的PWM输出引脚TIOCB0 GRB0输出比较或输入捕捉引脚；通道1和通道2和通道0一样，这里就不在作详解。

通道3和通道4在联合使用输出互补或复位同步PWM是有六个引脚都可以作为PWM的输出引脚。

1.4 寄存器配置2 寄存器功能2.1 定时器启动寄存器TSTR（八位寄存器）5,6,7位恒为1；4至0为依次为五个通道计数器开启停止的控制位置1开启，置0停止。

2.2 定时器同步寄存器TSNC(八位寄存器)5，6，7位恒为1,；4到0为依次为对应的计数器的独立运作还是同步运作控制位，置0则为独立运作，置1则为同步运作。

MCU灵活软件包启动文件说明

现在很多M C U都配套有软件包，不再像以前那样从零（汇编、寄存器）开始了。

而本文给大家描述的瑞萨M C U也是通过灵活软件包（F S P）进行快速初始化外设，下面就给大家讲讲F S P灵活软件包那些重要的内容。

F S P介绍FSP：F l e x i b l e S o f t w a r e P a c k a g e，即瑞萨M C U的软件包，类似于K e i l M D K中需要安装的软件包（K e i l.S T M32F1x x_D F P.2.4.0.p a c k）。

瑞萨灵活软件包（F S P）是一个灵活配置的软件包，旨在提供易于使用、可扩展、高质量的嵌入式系统设计软件。

它适用于R A系列的M C U，提供了统一直观的A P I，并有详细的解释和例程应用，可以按照客户不同的需求自动生成相应驱动程序。

启动文件说明启动文件是程序上电复位后执行的第一个程序。

它一般包括如下几个：1.初始化堆栈2.使能FPU3.定位中断向量表4.配置系统时钟5.启用CORTEX-M33栈监视器6.初始化C语言运行环境7.初始化变量SystemCoreClock，这个变量存放的是处理器时钟的频率8.初始化用于触发NVIC中断的ELC（事件链接控制）9.BSP初始化初始化堆栈D三初始化堆栈1、栈区（S t a c k）一种顺序数据结构，满足后进先出原则。

由编译器自动分配释放，存放函数的参数值，局部变量的值等。

栈特别方便用来保存/恢复调用现场。

在函数被调用时，其参数也会被压入发起调用的进程栈中，并待到调用结束后，函数的返回值也会被存放回栈中。

如果函数调用时，如果函数参数和局部变量较多，寄存器放不下，则需要适当增加栈区的大小。

2、堆区（h e a p）通常由程序员手动分配，使用m a l l o c和f r e e进行分配和释放。

注意，使用完需及时释放(f r e e)，否则容易造成内存泄漏。

3、e2S t u d i o中堆栈的设置宏“B S P_C F G_S T A C K_M A I N_B Y T E S”可以在F S P C o n f i g u r a t i o n的“B S P”属性栏中的“RA C o m m o n”中通过修改“M a i n s t a c k s i z e”设置，默认为1K B（0x400B y t e）。

瑞萨单片机在线升级操作说明

瑞萨单片机在线升级操作说明说明：共有两个程序代码，上电复位运行Bootload程序，然后检查EEPROM里面是否置位，如果置位，则需要进行APP代码更新，否则运行已有的APP代码。

一、使用瑞萨单片机R5F2L357C为例该单片机ROM资源如下，1、块A-D为数据闪存，未用。

2、默认ROM空间起始地址为0x4000h3、中断向量分为固定向量和可变向量，默认地址分别为：固定向量Fvector：0xFFD8-0xFFFF可变向量vector:0xFED8(至偏移256字节处)工程文件中可查：在fvector.c文件中#pragma sectaddress fvector,ROMDATA 0xFFD8我们要修改的两个程序代码空间分配为1、APP 用户程序代码编译出来有35.4K的空间，存放在块2、块3和块4，共40K的空间，地址为04000h-0DFFFh2、Bootload程序代码编译出来有5.2K的空间，存放在块0和块1，共8K的空间，地址为0E000h-0FFFFh。

二、Bootload程序代码制作1、修改ROM空间的起始地址，默认为0x4000，改为0xE000，如下所示。

编译完成后，可直接烧录该文件。

三、APP用户代码制作（I_Collector_Update）1、修改APP用户代码的固定向量和可变向量地址：将vector地址由0xFED8改为0x0DED8在fvector.c文件中#pragma sectaddress fvector,ROMDATA 0xffd8改为#pragma sectaddress fvector,ROMDATA 0xdfd8重新编译下，可以看出，地址不超出0x0e000，在块2范围内将编译的mot文件用FDT4.09工具打开另存为.bin文件，用UltraEdit打开.bin文件，将0x4000-0xe000地址以外的数据删除，保存。

此文件为在线烧录更新的文件。

这个文件可以用电脑串口发给单片机，单片机接收后IAP，自动运行。

瑞萨单片机基础软件安装(R8C)

学习瑞萨单片机，M16族下的R8C-2L、R8C-2K群单片机开发环境的安装由于仅仅有瑞萨的16位单片机R8C-2L、R8C-2K族（具体型号是R5F212L4，16K的FLASH 程序区，2K的RAM区），所以以下的均已R8C-2L、R8C-2K群为主，其实关于瑞萨的其他几款单片机，都是大同小异的，只需要认真按照教程操作一遍即可。

安装开发软件包括三项，分别是C和C++的编译器，IDE开发环境，下载工具软件。

第一项：C和C++的编译器，这是首先需要安装的，如果不按照这个顺序，安装IDE时会提示缺少相关元件的错误。

从瑞萨的官网下载名为nc30v600r00_ev的安装软件。

现在可以看出最新版本为V6.00版，安装过程中没有其它的注意事项，一路NEXT的就可以了，另外这个版本是兼容WIN7的！~第二项：IDE开发环境，这是第二个安装的，我们也可以从官网下载的，不过需要说明的是，下载这个软件时需要注_册瑞萨的会员，而且是不能使用迅雷的，注_册完毕便可以顺利的下载。

其它的注意事项也没有太多，这个软件是可以开发瑞萨的整个M16族的，其中就包括我们谈到的R8C族。

文件名为hewv40900u_full_update，同样上面的版本号码是V4.09，不过这个软件好像是有64K的代码限制，由于工程并不需要这么大的代码量，所以我没有破_解。

如果有网友有破_解方式的，也可以在这里分享一下吧！~第三项：下载工具软件，这是给单片机下载程序和仿真使用的。

但是瑞萨的E8A的调试器太贵了，动辄就要1000多元。

不过乐观一点是，好多类型的单片机提供了串口的下载方式，M16群也如此，而且它还是支持串口仿真的，现在你只需要一片MAX232或者PL2303即可。

M16cFousbDebuggerV103R00这是它的文件名，通常称这个软件为Fousb。

由于我们所使用的R8C-2L、R8C-2K群单片机为瑞萨较新的单片机，我们需要更新一下这个软件，你可以开着电脑，重启一下就会发现软件的官网同步更新了，不过更快捷的方式我们可以下载更新包R8C_UART_MCU_INST_E解压安装完之后，瑞萨的Fousb串口仿真和调试方式就此结束。

瑞萨MCU单片机资料 R5F100LEA RL78G13视频例程软件

可能由于自己技术水平不行，又接触此单片机和开发环境较少，好多东西看不太懂，而且教程中也有一部分不怎么清楚其生成原理，所以在自己使用生成其他代码时有许多困难。在我调式无线模块应用于瑞赛g14单片机时，纠结了好长时间，在51单片机上都可以使用，当我改写些定义后移植过来后还是出现好多问题，知道软件之间有所差别，但就是找不出来和如何去修改。比如所数据的发送用按键控制时，在51、430中IO口的输入设置使用后会自动拉高IO口，而瑞萨当中不行，必须要对相应的IO 口进行使用上拉电阻，不然程序会做无用功。还有一个问题就是无线接收部分，我到现在还没弄明白怎样去设置和调试。查了相关资料貌似是什么位选址的设置的问题，导致这个无线模块没有调试成功，其他功能基本已实现了。主要还是时间问题，我所在的电子技术协会，因为要带新生，基本上占据了大部分的双休日的时间。有两门考试也快临近了，英语四级也还有半个月，不知道临时抱佛脚有没有效果啊，好在四级词汇基本上背完了~遗憾的是可能真的没有时间在期限之前完成了，这几天会整理资料，将该发的帖子补上，毕竟是我在论坛里接的第一个项目，唉，算是有始有终吧萨MCU R5F100LEAF 英文描述：MCU CPU RL78G13 16BIT 64LQFP 技术规格：嵌入式微控制器; 系列:RL78/G13; 核心处理器:RL78; 芯体尺寸:16/32-位速度:32MHz; 连通性:CSI, I2C, LIN, UART/USART 外围设备:DMA, POR, PWM, WDT; 输入/输出数:48; 程序存储器容量:96KB (96K x 8); 程序存储器类型:闪存;EEPROM 大小:-;RAM 容量:8K x 8; 电压电源 (Vcc/Vdd):1.65 另外瑞萨集成开发环境有一个神器“代码生成器 code Generator” 能够生成MCU的底层驱动代码，相信这个东东一定能帮到大家。
