#130178 - The "gotcha" is that it has to be initialized Responding to: ???'s previous message |
before the busy flag will be valid, the HD44780 must be properly initialized. Those few steps in the initialization must be performed "open-loop," i.e. there is no feedback from the device available, so those steps must be properly timed.
The datasheet explains this in considerable detail. RE |
