    Got a chance recently to take a look at this and I believe the culprit might be the change made in #83 which writes bytes one at time instead of all at once as reverting this got my 7.5" HD display working again and suspect this may be the case for the V2 too.
    Happy to make a PR to sort this one out but seems like we may need to support both depending on the display, don't suppose we know which screens will need each write method?
