        hd44780_put(&lcd, chan_getc(sys_get_stdin()));
    }

My LCD is wired a little differently (pin assignments are different) than your example but it should still compile I would think.

Opening on PlatformIO Github site too.

The HD44780 driver is not yet part of any release. You probably read the documentation for the master branch, and not for the release 15.0.3 which is found on PlatformIO.

The plan is to create a new release soon.
