Hi I'm using a 16C84 to drive a 16x2 lcd display using 4 bit data transfer. To write data to the lcd the upper 4 bits are sent first but what about reading data. On reading data do I get the upper or lower 4 bits first? cheers Tom -- Tom Mullan http://www.shacc.demon.co.uk -- http://www.piclist.com#nomail Going offline?

> On reading data do I get the upper or lower 4 bits first? Reads/writes in 4-bit mode are both high nybble first. In both cases check the Busy flag only after two 4-bit transfers -- http://www.piclist.com#nomail Going offline?
