Re: RTC library for STM32F0

It should be possible, but probably requires some efforts ... First, it looks like F0 RTC is not simple counter like F1, but a BCD registers like F4. (I've done some implementation on F4 more than a year ago) But I don't think all register access are the same, only BCD similarities with F4, so a who...

Re: Red Pill or Blue Pill?

Right ! Core maturity is depending of what you wish to do.
Many libs can be shared between F1 and F4.
For example, almost 2 years ago, I've done lot of things with Netduino2Plus.
Networking, SdFat, LCD shield, etc...

Did you try to use scanf() without the _P ?

In my case, I've simply copied the STM32F1 SPI code, and commented the DMA.
Both that was actually more than 1 year ago, maybe things changed since then.

Re: from stm32 to stm8s

I would not mess with stm8, first simply because you need a different compiler, second, the resources are limited.
For small things/tasks, I'm rather using STM32F030, they are TSSOP20 as well, but same compiler as other STM32 can be use.

Re: Seeed Arch Max

I've used SPI with all DMA commented.
Here is the sketch in attachment.

No, I didn't play with "black F4 board", since I don't have one, but I played with Netduino2Plus which is also black ... ;)

From what I remember, it was the default code of stm32duino, without any special hacks.

EDIT : BTW, I almost never use SD lib, but using SdFat lib from Greiman.

It is clear ! The post above Rick's post is clearly shows that it ask for help about st-link issue, nothing related with the O-Scope thread.
And the funny thing is that there is even a st-link section on the forum with tons of thread.
