Arduino for STM32

Sorry, I did not put it on git.

@fpiSTM:
I have attached the zipped library, which includes a readme.txt that summarizes the most important things to know to use it.
You may distribute it to anybody interested.
So far I did not have any problem with it.
Please let me know if the readme file needs further clarifiation or details.

You are right, this is a good board especially for the applications where the CAN bus is needed.

You are right, my board has the discovery pin. And this one is not automatically handled by the core.

The fact is that this toggling was done in Roger's core, and is no more done in the STM32Duino core. So I must add the few lines above before initializing the Serial port.

At the time of flashing the code, the log says: maple_loader v0.1 Resetting to bootloader via DTR pulse Reset via USB Serial Failed! Did you select the right serial port?

The discussion you mention with your link relates to the bootloader 2.0.
I this relates to the bootloader code stored in flash, It is not my case since the boards are delivered since the beginning with the original maple bootloader.
Which new version did you mention? When will it be available?

I am porting several sketches from Roger's core to Arduino IDE + STM32Duino core. I am using an Olimexino STM32 board, which includes a physical USB interface directly to the USB pins of the STM32F103RBT6, and the original Maple bootloader. I compile using the option "USB CDC generic serial&quo...

I eventually found what was wrong. A statement did end with a ":" instead of a ";". This fooled the IDE mechanism, but instead of flagging the mistake, it behaved badly. After changing this character to a ";", the IDE worked well again. It is always difficult to find a ...

It has been several times I experience this issue, over several years. I am using the Arduino IDE 1.8.12 with the STM32Duino package installed. I have a large sketch (2285 lines after merging). There are 11 different identifiers that switch blocks of code using many nested #ifdef...#else...#endif st...
