Re: LCD BARgraphs
Chris, Have you written code to look at the BUSY bit? I think you would be a bit supprised to find out just how long it takes some SPOOLED commands to execute. I have had this problem before with some NewHaven displays and with there lack of documentation you just have to figure out things on your own. What I would do is, write a routine to first set an output bit and connect a scope, then look at the busy bit after you send a command string to the display. re-check the busy bit to be clear, reset the output bit when the bit is clear and you would be supprised. Why do you think they make it available? You as the programmer are supposed to knowlegable enough to use the BUSY bit. Otherwise, don't complain about someone elses routines not working unless you know what the problem is....... Happy Thanksgiving......
