Arduino for STM32

I have the same problem as you, cant get it working with STM core but it works on Roger core! USB cable didn't fix that...

Hi I have an SSD1322 LCD panel that has a 4-pin SPI connection. The panel works fine with Arduino UNO under Hardware and Software SPI mode. In the FPS test that comes with U8G2 example library, it scores 13 fps which is normal. Note I am using this board manager http://dan.drown.org/stm32duino/packa...
