Arduino for STM32

Hi, For analogWrite on PA4 and PA5, this is the normal behaviour as there is no timer linked to those pins: https://github.com/stm32duino/Arduino_Tools/blob/31f3d43d620878dccbf658f65095f66fec9809b2/src/genpinmap/Arduino/STM32F103R(8-B)Tx/PeripheralPins.c#L88-L136 So it operates like a digital pin: 0...

Yes

Which core you used and how?
To get support please be more precise

Hi,

You should have a look at this example:
https://github.com/stm32duino/STM32Exam ... istics.ino

Using the linker script definitions _estack and _sdata should do the trick

But during execution not build time.

Welcome back sheepdol
Nice to see you and nice presentation.

Thanks @ag123

For STM32 Core, they are available in the STM32Examples library:

• Dhrystone

• Whetstone
  • DoublePrecision
  • SinglePrecision

Main info: Introduce MP1 (cortex M) support HardwareSerial Half duplex Allow to enable HAL module only Binary file size decreased (up to 4kb) CMSIS DSP could be used Support precompiled libraries Added the repeated-start feature in I2C driver Full detail here: https://github.com/stm32duino/Arduino_...

This is the default configuration and currently, I would keep it as it is. IIWR, Roger set a smaller size (64k) so this is already higher than before. The forumconfiguration will evolve, it's just reopen so I guess some tuning will be required. At this time, let's see how this qoes. I'm agree with m...

This application note could be a good starting point to understand STM32 GPIO: https://www.st.com/content/ccc/resource/technical/document/application_note/group0/13/c0/f6/6c/29/3b/47/b3/DM00315319/files/DM00315319.pdf/jcr:content/translations/en.DM00315319.pdf DDRx as far as I remember is the Regist...

Christmas release ... perhaps with a new blinky LED API for flashy tree lights?

Right and also some gifts under the tree!
