Hi all,

 

I am trying to use the Gravity LCD1602 v1.1 I2C LCD (code BLWBBA - blue backlight only) with the STM32 Nucleo F446RE board. I have used this LCD in the past with an Arduino, and the custom DFRobot I2C LCD library worked excellently. However, I have not found any such library for the STM32 Nucleo, and a lot of the standard STM32 I2C LCD libraries either seem to be written for the PCF8574 I2C to parallel interface chip, and/or cannot control the Gravity's backlight.

 

Does anyone have experience using this LCD with the STM32 platform, or know of a good resource to explore that might be helpful?

 

Thank you for your assistance.

Could you please specify the exact SKU? There are too many iic screens. I'm not sure which one you are using.
