#152276 - Dual Init Responding to: ???'s previous message |
When two controllers are present on a display module do not forget that it is necessary to run the initialize and setup routine to each display controller in turn.
On one occasion a long time back I heard of an example where someone tried to do the initialize to both controllers at the same time by driving both E's at the same time. I strongly discourage this type of attempt to save a few milliseconds at startup. Michael Karas |

Have you considered looking for a datasheet? | 01/01/70 00:00 | |
I have had some luck! | 01/01/70 00:00 | |
You could, of course, trace the circuit | 01/01/70 00:00 | |
