  1. [SOLVED] Adafruit_ILI9341_STM – hardware scrolling broken

    zoomx

    …1 LCD that I have doesn’t work with Arduino at 5V (they are all white) but works with STM32 at 3.3V despite that they were announced as Arduino compatible. I never tested the SD card adapter but I believe that I have the resistor too.

    … times more powerful than the Arduino nano to make it work there is where I found the STM32 and start to post here The research lead me to BCM, I know my own PWM implementation sucks, and I’m interested to know what you have in mind at this scale. Remember tha…
  3. [SOLVED] Error with i2cdev library

    fpiSTM

    As it use Wire class from the core, it should not need specific update for stm32. I think the original question is why it does not built anymore. Edit: Tested with Arduino_Core_STM32 and it’s ok.
