Jorgen's example tweaked to use rows instead of y co-ordinates.

The Flowcode component was back. Very odd. Deleted again.
It's all very odd - gone back to only working at 100kHz and then only for a brief while. Gremlins? Rod Serling is sitting in the corner and something very odd is about to occur?
Then - I found and swapped to a 64 pixel display. One of the jumpers 'failed'. (Should have build Iain's 'jumper tester')
The 64 pixel display needs 'interlaced' - so added that. Mines also needs inverted set to true (in the FC component - what I have as 'inverted' is 'if 1' (so always))
Still locking up at 400kHz - I might go for a little lie down in a dark place...
So - working a (rather dim) 64 * 128 pixel display with 8 rows of text too..
Try this:

Just tested on an esp32 - i2c running at 1MHz works okay so not sure why Uno is only working at 100kHz

Check the value of interlaced (new property) - off for 32 pixel display on for 64...
y is now row 0..3 (or 0..7)
