Add/link hd44780u.c to your project and include hd44780u.h. That's it. Implement your low-level function of delay in microseconds needed for the correct working of this library:
void HD44780UDelayUS(volatile uint32_t micros)
{
// Wait time delay in microseconds.
}Define HD44780U_INCLUDE_CONFIG as compiler switch (e.g. gcc -DHD44780U_INCLUDE_CONFIG) to include a "hd44780u_config.h" definition file.
