[url=http://forums.parallax.com/forums/default.aspx?f=7&m=194365]http://forums.parallax.com/forums/default.aspx?f=7&m=194365[/url] This display is unique in that the 16 rows (up/down) are directly tied to the 2 sets of 16 columns (left/right). See AD-501-B.jpg (attachment). So far I can enter in WDATA statements to control what is on the 2 sets of 16 columns and then directly scan from top to bottom (16 rows) the WDATA in. Since the rows are not independent of the columns, I can't figure out how to use an interrupt to scan in the rows fast enough and correctly. It is a combination of setting HIGH's and LOWs on the /Latch, /Strobe, SIN1, SIN2, SIN3 and the CLOCK. Can someone offer some insight to how this might be done? BTW: I don't have any problem with brightness as the LC7932M LED drivers that this AD-501-B module uses. Very nice and bright but have to use a separate 5vdc 20A power supply (draws ~2 A) for the AD-501-B module. It has been difficult figuring this out since the datasheet is in THAI. Any Help would be appreciated! Thank you. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=199459 Need assistance?
