They are literally all the same, and driven by an HD44780 controller chip. If you can't find C libraries tailored for the Pico then copy some Arduino code.Hello,
I see several screens 4x20 on youtube connected to the pico. Unfortunately all are using python. Since I must write in c, can somebody recommend which screen to use? (with c librairies available).
Thanks.
The HD44780 itself is controlled via a parallel interface. It would be worth studying how that works. The I2C interface is basically just a port expander which allows a two-wire I2C connection to drive the parallel interface.
