打开 USB 驱动.EXE 可以看到如下画面,点击 INSTALL 即可安装(注意,此时请先不要连 接开发板与计算机)
打开检测程序,此时连接开发板与计算机,等待系统发现新硬件,让其自动安装驱动即可, 注意忽略数字认证警告。
如果安装成功既可看到 RoboElc 提示“成功打开 CH341 设备” 。注意一定要正确安装驱动, 否则无法下载程序。
绿色底板 板子跳线已经事先接插正确,当您将 USB 供电插上时,可以看到测试程序(流水灯、蜂鸣 器、数码管、DA 指示灯) 注意:8051 核心板上晶振跳线帽必须接插 以下为 AVR 核心板图片
待学习 AVR(开发板支持 ATMega16 等)时请将 8051 核心板拔下,插入 AVR 核心板,注 意方向朝上。 建议用户首先学习 8051,将内部资源等知识学习扎实再学习 AVR,我们不建议在基础知识 还没有打牢的情况下学习额外知识。 如果用户在学习好 8051 后,可以自己动手制作 STC12 系列增强型 51 核心板用于练习。

奋斗版 STM32 开发板例程详解———FM 收音机例程FM 收音机例程实验平台:奋斗版STM32开发板V2,V3 实验内容:板子加电后,通过串口1输出操作菜单。

通过串口助手工具可以操作FM 收音机功能,具有搜索, 选台等功能。

收音机模块选用TEA5767 FM收音机模块。

这个模块的外形及引脚如下所示• 高灵敏度(使用低噪声射频输入放大器 ) • 兼容美国/欧洲(87.5 to 108 MHz)和日本(76 to 91MHz)调频波段 • 预调谐接收日本电视伴音至108 MHz • 高放自动增益控制(AGC)电路 • LC调谐振荡用低成本固定芯片 • 调频中频选择在内部完成,中频免调 • 三种振荡基准频率输入32.768K、13M、 6.5M • 锁相环调谐系统 • 由总线模式管脚来选择I2C总线模式或三线模式 • 由总线输出7位中频计数,由总线输出4位电平 • 软静音,立体声消噪(SNC),高电平切割 (HCC) • 软静音,立体声消噪(SNC),高电平切割 (HCC)能通过总线关断 •免调谐立体声解码器,自动搜索调谐功能淘宝店铺:1奋斗版 STM32 开发板例程详解———FM 收音机例程1. 应用实例1.1. 设计要求板子加电后,通过串口1的输出输入信息可以操作FM收音机搜索,选台。

奋斗开发板MINI入门手册

奋斗开发板MINI入门手册

奋斗版STM32开发板MINI入门手册基础知识篇作为STM32的初学者,首先需要了解硬件资源, STM32是意法半导体推出的基于CoreTex-M3内核的32位ARM, 目前主要有5个系列、奋斗版STM32开发板的MINI及V3选用了STM32F103VET6作为开发板的MCU。

这个芯片属于STM32F103系列的高容量芯片, QFP100封装, 主要特征:64K片内SRAM 512K片内FLASH。

具有FSMC接口(并行外设外设接口,TFT模块就是通过这个连接的),SDIO 4位接口(SD 卡的专用接口,速度更高)。

之所以选用这个芯片作为开发板的MCU,主要是基于以下几点:1-------容量大,是STM32系列里,容量最大的芯片2-------体积适中 QFP100脚封装,从大型设备到手持设备都可以选用。

3-------FSMC接口 由于板上设计有TFT模块, 因此选用具有FSMC接口的芯片是必然的。

4-------SDIO接口 作为一个嵌入式的平台,大容量SD存储是必须考虑的, 可以在SD上建立文件系统及大容量文件存取。

5-------性价比高, 该芯片的批量采购价格在30元左右,渠道稳定,适合工程选用。

很多用户先前都是从51平台转过来的, 对单片机的经验还停留在51带给我们的简单易用上,51单片机的资源简单,且口线定义唯一。

相对高端的51型单片机(如SILICON C8051F系列,AVR等)可以做到一定的口线复用(就是一个口线可以具有多种复用功能),51在处理对计算速度及控制速度相对不高的应用,还是具有很好的性价比及应用性。

近几年,随着应用技术的发展, 产品对嵌入式技术要求越来越高,51单片机已经不能满足复杂嵌入式应用要求, 在ARM技术发展过程中,coretex-M3内核应运而生,它的各项能力使得它成为微控领域之王,STM32是这种内核的产物, 是目前coretex-M3内核平台里最具性价比的平台,可以预见,未来几年里,STM32会很快占据微控平台市场。

基础知识篇
作为 STM32 的初学者,首先需要了解硬件资源, STM32 是意法半导体推出的基于 CoreTex-M3 内核的 32 位 ARM, 目前主要有 5 个系列、
奋斗版 STM32 开发板的 V3.1 选用了 STM32F103VET6 作为开发板的 MCU。这个芯片属于 STM32F103 系列的高容量芯片, QFP100 封装, 主要特征:64K 片内 SRAM 512K 片内 FLASH。 具有 FSMC 接口(并行外设外设接口,TFT 模块就是通过这个连接的),SDIO 4 位接口(SD 卡的专用接口,速度更高)。 之所以选用这个芯片作为开发板的 MCU,主要是基于以下几点: 1-------容量大,是 STM32 系列里,容量最大的芯片 2-------体积适中 QFP100 脚封装,从大型设备到手持设备都可以选用。 3-------FSMC 接口 由于板上设计有 TFT 模块, 因此选用具有 FSMC 接口的芯片是必然的。 4-------SDIO 接口 作为一个嵌入式的平台,大容量 SD 存储是必须考虑的, 可以在 SD 上 建立文件系统及大容量文件存取。 5-------性价比高, 该芯片的批量采购价格在 30 元左右,渠道稳定,适合工程选用。
