As for polling the busy bit - this seems to be a bit of a contentious issue. If you poll the busy bit, you need to add a timeout as the displays can and do die. Well, this might depend on the particular application. Namely, there might be applications, where it is desirable to the application to die when the display is dead!? JW |
