  • Nucleo F401RE no startup

    Hi.

    I downloaded and extracted the 'en.STM32Cube_FW_F4_V1.24.0.zip' and 'extracted the en.patch_cubefw_f4.zip' over it. Building the GPIO_IOToggle (NUCLEO-F401RE board) with MKD-ARM is 100% okay with no errors or warnings. After download with the IDE download…

  • Nucleo64 - STM32F334R8 board not shown as Nucleo board in Keil

    I have the board Nucleo-64 STM32F334. When I opened my Keil and created a project with this microcontroller name it is not showing that it is a Nucleo board in the Board support section of the "Manage run-time environment". I ignored it and started…

  • Any Method to trigger/start FreeRTOS task from normal STM32 ISR??

    Hello Folks,

    What is the most effecient method to start a freeRTOS task only after an ISR is completed and flag or something set by ISR that triggers freeRTOS task.

    Lets take an example scenario , I have STM32F3 nucleo board in which i would like to toggle…

  • Getting started with NUCLEO-F411RE and ESP8266

    I received my STM32F411RE Nucleo board last weekend (Thanks to Carissa for selecting my idea). Overall board looks good and worth it's price with powerful STM32F411RE and on board ST Link debugger. The only drawback I noticed was missing USB OTG connector…

  • STM32 Nucleo系列的板子如何实现拖固件至U盘升级固件的呢？

    STM32 Nucleo的开发板，装完驱动后，接入电脑，此时电脑会模拟一个容量较小的U盘，这个容量应该就是MCU内部flash剩余的空间大小了。

    我们可以通过mbed或MDK-ARM编译一个bin文件，然后直接把该bin文件拖到该MCU模拟的U盘目录中即可完成MCU固件的烧录，请问此方式是如何实现的呢？哪有相关的资料？

    ST的UM0412手册讲述了通过DFU方式升级固件，DFU和上述显然不同，DFU使用起来更加复杂。

    是否是如下实现呢：

    STM32 Nucleo板子都有一个编程器（可掰开的上半部分），一般由F103充当…

  • 关于STM32F401 Nucleo的学习问题

         诸位ARM社区大神你们好！我是一名在校学生，因才加活动有幸获得Nucleo开发板一枚，想要以他为基础进行深入的学习。因为手里只有这一块板子，需要购买些外设，做些有意思的东西。希望大家能够帮助我，提些建议。sunsmile.armmbedchina001

  • 在NUCLEO-F411RE上使用MicroPython

    在MicroPython的源码中，已经包含了NUCLEO-F411RE开发板，大家只要重新编译一下，将固件下载进去就可以运行。编译的方法请参考小钢炮那个帖子，就不重复了。下面说明其他需要注意问题。

      • 虽然NUCLEO-F411RE开发板带有Mbed编程接口，但是不能直接将HEX文件复制到Mbed磁盘进行更新，需要用STM32     ST-LINK Utility或其他软件下载。

  • ARM大学计划Workshop，让更多的年轻人接触mbed

    大家好，我是ARM中文社区斑竹songbin。

    前天，我给大家介绍了ARM大学计划在上海举行的一年一度盛会，ARM高校教师峰会：ARM的大学计划，你心动了吗。

    在会上，ARM和STMicroelectronics 支持高校创建了STM32创新基地，并捐赠了基于ARM mbed 的开发工具。

    大家也知道，ARM和我们的合作伙伴是实干型的，我们第二天就一起为所有创新基地的老师举办了一个Workshop，帮助大家掌握mbed技术。

    因为我和我们的大学计划经理davidchen合作一直很愉快，所以此次也有幸一起和老师们参加并体验了这个Workshop…
