楼主您好，
我尝试移植F4的代码到我的F407板子上面，结果遇到了问题。

1. 编译通过，ADC工作正常，VCP（CDC）串口也有了，可是ScopeGUI打不开VCP，当然也收不到数据。
2. 检查发现，用其他终端软件也打不开这个VCP，当然也收不到数据。
3. 进一步检查后发现，可能与编译器有关。 为了找问题，我单独开了一个CDC工程，同一套代码在MDK和CLion（Win10）下面都能正常编译，但是CLion出来的代码就发生CDC不正常，与上面说的一样，PC终端软件收不到CDC_TransmitFS发送的打印内容。 而MDK编译出来的就正常。
   同时，我Win10电脑的CLion系统，编译F103的那一套ScopeMCU（master）代码就全部工作正常。 我的CubeMX也是最新版本。

您遇到过这种问题吗？谢谢。

Hi!

Thanks for your project! It works great.
I burned my PA0 input and trying to remap any analog pins but don't know how to do it :)

When I import as an existing project and click Build:

**** Build of configuration Debug for project ScopeMCU ****

Nothing to build for project ScopeMCU

I tried re-generating the project with CubeMX. No luck.

Ubuntu 22.04 LTS
STM32CubeIDE version: 1.10.1

我看说明里面特别指出

为了采样精度和校准，当前最高采样率: 70ksps

这个限制是在那实现的，如果不考虑精度，只是要看个大概，能否达到1M?
如何修改?

The GUI does not allow setting the sampling frequency larger than 70kHz. And I see that the picture is breaking already at 70kHz.

But I did see others are using an STM32F103-based oscilloscope to get 1MSa sampling rate. Is it possible to achieve this with built-in ADC only? Or USB communication limits the speed to be lower than 70kHz? Will the situation improve if I switch to STM32F429 Discovery board with a (presumably) better ADC?

你好，我没有找到log.h，请问这个头文件有什么用
