Improvement/completion of epd1in54_V2 Code about e-paper HOT 7 CLOSED

There's a good amount of information on the wiki in the "Codes description" tab. I was able to use that to do some basic things with this display.

from e-paper.

Hi MartyMacGyver,
The wiki will not help in this case. I'm familar of using the "old version" of epaper 1.54" and for simple example the function SetFrameMemory() is not implemented in the version 1.54V2 in epd1in54.cpp.

Ah... I see your point. It seems what's implemented varied widely by device and revision.

Hi Knowless
I put back all the functionality of (V1) . Please have a look

Hi Waldow your link doesn't work.
I did track your code down and even though the paint works the image doesn't display correctly.
This is on an epaper that arrived today.
I can't for the life of me understand why all the code adds WaitUntilIdle at the end of the method call.
This is not a threaded environment. why not just add it at the start of a method and block the code there.
I have implemented this in my code and it vastly improves the responsiveness of the code.
The Arduino can get on with other jobs. Then when it needs to send something to the epaper it is prepared to wait.
Please Please fix the include spi.h and the include arduino.h
it is Arduino.h and SPI.h
windows my not care but linux does and every time I download new code I have to fix it.
Sorry for the rant but it is very frustrating.
Something that worked really nicely in the old code no longer works at all.

@Yardie- Yes WaitUntilIdle is a unnecessary evil . The whole busy waiting is used a lot .
