Arduino for STM32

Thank you, I will try. However, I am not sure I will get the USB serial module functional. It should be included in the core of any sketch, and initialized prior to calling Loop, or maybe prior to calling Setup. The DTR virtual signal of the com port is used to actuate the DISC pin. Is this function...

I went a bit further in my investigation. I had chosen for the chip "STM103xxx" and for the variant, "Maple mini". I overlooked the fact that the Maple Mini uses a smaller footprint chip, the STM103C, whereas the Olimexino board uses the STM103R. Thus the pin allocation was diffe...

I am investigating my problem that I describe in my previous topic here about compilation on Olimex (maple) board. For so, I have connected a st-link to my board, and I would like to directly flash the board with the .bin file last generated by the compilation in Arduino. I did a try, but in my firs...

Hi all, I have developped a set of applications for the Olimexino STM32 board (a clone of Maple) back in 2014, first using the Maple environment, then I moved to the Arduino 1.8.3 IDE with Roger's package that was constantly evolving through the years. I still use it now, my developments are stable ...

Thanks, it worked.

Hi, I am looking for the definition of the serial channels for the maple-style boards. I use Arduino IDE 1.8.12 and the latest core from githup. Apparently, the identifier Serial represents the USB serial port. What is then the name of the physical ports? I tried Serial2, but this produces an "...

Hi all,
so far it does not seem this library is available. I did some work in the Libmaple time and achieved a HardwareCAN library to add to the previous core from Roger.
I am in the process of moving towards this new core but I did not succeed in porting my library into it. Any hint?

Thank you, this problem is solved. However, I have yet another problem. In my sketch I massively used the __FLASH__ attribute to store string constants in flash and spare the RAM. This attribute is not accepted by the compiler any more. What is the new syntax for this?

After years of use of the arduino IDE + Roger's core that kept evolving, I had a rather poor development environment that I would be unable to rebuild in case of a crash, due to the number of fixes and tweaks that were accumulated over time. I have decided to build a new environment on a fresh machi...

I ended up into taking my scope to see the signals on the USB data lines. One of them stays at level zero permanently, whereas I see traffic on the other one. It seems really that the USB hardware is faulty. Too bad.
