Stm32f103c8t6 evaluation board

Hi!

I require your help regarding a problem I’m encountering with my new STM 32 board.
The processor is ARM 3 and I want to control it using the Arduino IDE. Has anyone else done this before?
Thank you so much in advance for your help!

Yes.
That answers the question you asked.
But I suspect you meant to ask “how do I do it?”

Thanks for the very useful link, I have just joined the forum and what with registering, confirming the email regarding the registration, opening a new topic etc I may not have phrased my question properly for which I apologise.

No problem. It happens. But a well-formed question does make it a lot easier for people to help you.
I have never used the Arduino IDE for an ST processor, so I have no personal experience. But Google had lots of links. The one I posted looked like a good starting point. If you have other questions please do post them.
Welcome aboard!
