<h1>LCD library</h1><hr><a name="_details"></a><h2>Detailed Description</h2>
Basic routines for interfacing a HD44780U-based text LCD display.
<p>
<div class="fragment"><pre class="fragment"><span class="preprocessor"> #include <lcd.h></span>
</pre></div><p>
Originally based on Volker Oth's LCD library, changed <a class="el" href="group__pfleury__lcd.html#gedadae82796028f0eb4877c2633a2093">lcd_init()</a>, added additional constants for <a class="el" href="group__pfleury__lcd.html#gc6aa7e0d522b4c013ebeae1ccd23d510">lcd_command()</a>, added 4-bit I/O mode, improved and optimized code.<p>
Library can be operated in memory mapped mode (LCD_IO_MODE=0) or in 4-bit IO port mode (LCD_IO_MODE=1). 8-bit IO port mode not supported.<p>
Memory mapped mode compatible with Kanda STK200, but supports also generation of R/W signal through A8 address line.<p>
