Re: Readonly Serial Multiple Ports

Or, if you need more processing power, for ~ same price a STM32F407VET (black or mini) board would also make it (4 USART + 2UART).

Re: Volatile Qualifier

Well, guys, I've found the issue. Very simple. Two files from the gcc pakage uses " __io " as input parameter for some functions. This is just an unfortunate coincidence that the Arduino_STM32 core uses the same term to define volatile... The Teensy core is not sensitive to this because it uses the ...

Re: Volatile Qualifier

There are tens of libraries which works fine with the Arduino_STM32, so I don't think there is a problem with the core, at least not alone. Just because you see a core file most frequently listed in the error message list, does not unambiguously mean that it is erroneous. And, as you could test and ...

Re: adafruit_ILI9341_STM for SPI2

It is clear, that it does not work if you use STlink and don't define SERIAL_USB. How old is your repository local copy? Because PB3/PB4/PA15 are used by the debug interface, they were previously reserved for debugging, and not available as normal IO pins. With this patch this problem has been fixed...

Re: Volatile Qualifier

With more recent GCC Version 7-2017-q4 the only errors I can see are about min() and max() functions nothing about volatile qualifier etc. IMO, this is a clear sign that it is related to the combination library & gcc version, and not the core. You should ask the library owner for GCC version requir...

Re: Volatile Qualifier

I think the problem is with this file, part of the ARM toolchain (gcc): c:\users\Shujaat\appdata\local\arduino15\packages\arduino\tools\arm-none-eabi-gcc\4.8.3-2014q1\arm-none-eabi\include\c++\4.8.3\bits\locale_facets.tcc: In member function '_InIter std::num_get<_CharT, _InIter>::_M_extract_float(_...

Re: Volatile Qualifier

Is this the sketch: https://github.com/bolderflight/uNavAHRS/blob/master/examples/uNavAHRS-with-MPU9250/uNavAHRS_MPU9250/uNavAHRS_MPU9250.ino ? Please post (at least a part of) Arduino IDE error messages to see which library and gcc files are involved. I think you should uninstall the Arduino SAm bo...
