你好！请问你提出的问题解决了吗？是否可以分享一下经验？

博主你好，请问你的407VET6无法烧录的问题后续有找到问题吗，我也遇到了一样的问题，程序过一段时间会突然就无法烧录，我确定程序里没有任何操作option字节的操作，而且极难复现，大部分时间突发的。

这个问题是，电脑可以识别到ST-linkV3，但是貌似是识别的有问题，卸载板载的ST-link V3驱动然后再重新安装一次就可以了！

板子上的绿灯一直在闪烁，开发板正在发送广播，BLE_p2pServer 广播一段时间（一分钟后）可能会停止广播。 请换一个版本的 App试试，使用ST BLE ToolBox 或lightblue，再重新烧录一个BLE_Heatrate 的demo 试试 我们在使用STM32WB09开发板时候，测试时，请把板子天线位置和手机靠的近一点。

根据我刚才的反复验证测试，跟你有同样的理解和质疑。这里的两句基本是矛盾的。 结合你、我的测试，初步认为，在DAMDF=0b11时，文档中提到的“when 4 new 8-bit values are available”应该是有问题的。 实际情况是每次DMA请求传输两个8位的ADC转换结果，而不是等待4个新的8位值，使用的是CDR寄存器的低半字。 而且这个结果也是可以理解的。

https://www.st.com/resource/en/user_manual/um3259-stm32-motor-control-sdk--6step-firmware-sensorless-parameter-optimization-stmicroelectronics.pdf这篇文档说了pwm频率要有电频率的60倍以上，不知道实际的极限是多少

类似的小疏忽 防不胜防~！😄 谢谢反馈~！

这里提醒你几点： 1、发送前，GPIO脚的电平是确定的，一般来说属于空闲电平； 2、发送时保证DMA是从头开始的，不是半中间状态； 3、再次发送前，前次的发送是完成了的。 我这边使用STM32H743 TIM1做了测试，没有啥问题。 !(data/attachment/forum/202412/09/170943hjzs5ssrsj8ee3e7.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/300 "image.png")

两个模块是独立的，自然可以各做各的事情。 硬件I2C去读24c芯片，当然可以，库里都有现存的API函数可以调用。 查询方式、中断方式、DMA方式的都有。 Repository\STM32Cube_FW_F4_V1.28.1\Projects\STM32F4-Discovery\Examples\I2C

为了增加积分评论一下

butterflyspring

那你上电不初始化它，是否还闪？ 如果不闪，就先设置输出高。

butterflyspring

每次擦除都是同一个区域，基本上是固定逻辑引起的，通常和软件关系比较大。 芯片通常有写保护功能，检查一下，将对应的区域写保护，这样就能通过打补丁的方式解决。 否则需要找出问题所在，通常这种逻辑都比较隐蔽，（当然一些偏移量的计算，栈溢出可以容易验证）。毕竟开发时都是按正常逻辑设计的。 上电和掉电复位的确会引起一些故障，也正如你所说，是随机的故障概率比较大。

好的 谢谢

从上面分析看门狗是正常的，可能是程序没有执行，可以在喂狗的操作中，或者开个定时器，定时输出波形。另外可以增加串口通讯，测试收发数据。如果还不好确定，看一下与显示屏的通讯是否还有波形再输出。
