Problem with Hardware Timer example on STM32L476RG.

Hello friends, I am trying unsuccessfully to test the Timebase_callback.ino example found at https://github.com/stm32duino/wiki/wiki/HardwareTimer-library. I just changed output D2 to PA5, which is Led1 on the board. Unfortunately it didn't work, the led just doesn't flash ... I found the topic http...

Re: LCD i2c for STM32 with ArduinoIDE.

The "hello world" example from https://github.com/johnrickman/LiquidCrystal_I2C compiles without error for the STM32L476RG board. Sketch uses 14116 bytes (1%) of program storage space. Maximum is 1048576 bytes. Global variables use 824 bytes (0%) of dynamic memory, leaving 97480 bytes for...

Re: LCD i2c for STM32 with ArduinoIDE.

So if you want to use this library you will have to modify it to fix that. I've added this to LCD.h after the last #include: #ifdef LCD #undef LCD #endif And it allows to build. Hi fpiSTM, The library you referred to is the same library I was already using to compile the program for Arduino Uno. I ...

Re: LCD i2c for STM32 with ArduinoIDE.

The Juraj, Did you try to compile on your ArduinoIDE the program "Injetor_v.09" that I sent to http://tbf.me/a/CiQu9 for the STM32L476RG board? I had tried this before, as I said, and there were numerous errors on the dependencies. After that I tried to avoid using libraries, putting all t...

Re: Trying to port Arduino programs to STM32 boards.

Yes, the simplest way is the one you mentioned. However, it is interesting to see that there is more than one way to do the same thing, following the syntax that appears in "pins_arduino.h".

LCD i2c for STM32 with ArduinoIDE.

Hello friends! I've been doing some experiments, trying to compile a simple i2c communication program with an LCD display using ArduinoIDE to work on the STM32L476RG. Again, nothing is so simple ... In the process of compiling the program, numerous errors arise. Researching a little more, I discover...
