for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. Now a days, ...

I2C offers a variety of speeds while requiring only two wires (clock and data), which makes it significantly easier to handle than alternatives, such as SPI. Within the STM32 family of MCUs ...

consider HID over I2C, it’s a standardized protocol with wide software and peripheral support, easily implementable and low-power. What’s more, [benedekkupper] gives you an example STM32 ...
