<p><b>New page</b></p><div>[[Category:LCD]]<br />
BASCOM supports LCD displays in a way that you can choose all pins random. This is great for making a simple PCB but has the disadvantage of more code usage. BASCOM also does not use the WR-pin so that you can use this pin for other purposes.<br />
<br />
The LCD4BUSY.LIB can be used when timing is critical.<br />
<br />
The default LCD library uses delays to wait until the LCD is ready. The lcd4busy.lib is using an additional pin (WR) to read the status flag of the LCD.<br />
<br />
The db4-db7 pins of the LCD must be connected to the higher nibble of the port.<br />
<br />
The other pins can be defined.<br />
