I want to use stm32duino to control 5110, I use the library http://www.rinkydinkelectronics.com/download.php?f=LCD5110_Basic.zip
Before, I use arduino pro mini to control 5110 by this library, it works well. But when I use stm32, it fails. Whether this library is not suitable for stm32duino ? If so, which library is suitable for me ?
