We are making our DAC output a sinusoid of variable frequency depending on a button we press. The DAC does work when we hard code which button WE press but not with UART. With the UART handler (used for receiving the "button" we press and incrementing…
ARM M4 to BLUEGIGA module, Multithreading, and Data Buffering
Hello, I am looking for information about programming an ARM M4 firmware to basically broadcast serial information to a bluegiga WF121-A wifi module. My device will receive 2 serial inputs and I want the serial input packets to be sniffed and broadcasted…

How to create a CMSIS project for DiscoveryF407VG board?
I have downloaded Keil 5.24a, and Arm cortex-M legacy support, when I want to create a new project, in micro selection step, in Software Packs there is no STM32F407VG micro, but there is STM32F407VGTx micro instead, and I don't know what is the difference…

请问core_cm3.c文件对于stm32f103来说是不是多余的？
我是一名stm32初学者。购买了一个开发板并附带了视频教学。在新建一个stm32工程中，视频里要求将一系列的文件添加到工程并选择好path。其中有一个叫core_cm3.c的文件，我有一次忘记添加了，但编译居然没有出错而且程序能运行。后来我又试了一下把core_cm3.c删除了，但keil依旧没有报错。stm32说明书里讲到core_cm3.c这个文件对stm32是很重要的，那我想知道问什么不添加core_cm3.c不会报错？而且stm32f10x.h文件里面#include<core_cm3.c…

Nucleo-F031K6 mbed初步
1. 开箱
打开包装后，共有2件：手册和开发板。开发板如下图示：
2. 上电并安装驱动
使用micro USB口接入电脑，此时LD1电源灯亮，如果未安装驱动或驱动版本过低，则其它LED灯不亮且电脑提示安装驱动。下载最新的ST-LINK驱动（http://www.st.com/web/en/catalog/tools/PF260219），在系统提示的找到新硬件窗口中，根据提示安装驱动：
根据系统提示，安装所有其它新硬件的驱动，把所有驱动目录都指向ST-LINK即可。

STM32F10x 学习笔记10（基本定时器）
大容量的STM32F101xx、STM32F103xx系列和互联型产品中包含了两个基本定时器，TIM6和TIM7。这两个定时器功能非常简单，基本上和SysTick 定时器相当。
但是我在使用的时候确是费了一番周折才调试通过，所以还是应该将这两个定时器的使用方法好好的写一写。
基本定时器TIM6和TIM7各包含一个16位自动装载计数器，由各自的可编程预分频器驱动。简单的说两个定时器是从0计数到N（由自动装载计数器来确定N的具体值），然后复位回0 重新计数。每次复位到0 的时候可以产生对应的中断信号，或…
