I have succeeded in driving the AXE134Y 4 line by 20 character display in graphic mode using these:
SEROUT oled, speed, (254,31) 'Graphic mode, bright
SEROUT oled, speed, (254, 1) 'Clear Display
Then I can address the top 2 rows of the display, using SEROUT oled, speed, (254,64) and SEROUT oled, speed, (254,65).
But I can't find a way to access lines 3 and 4. I tried writing more than 100 bytes to line 1 (20 characters by 5 pixels) but it rolled over to line 2. Similarly, writing >100 to line 2 rolls back to line 1.
I've also tried positioning the cursor e.g. SEROUT oled, speed, (254,148) but that seems to move the cursor pixel-wise beyond 128 at row 1, pixel 1. Even SEROUT oled, speed, (254,240) started writing part way along line 1.
And increasing 64 and 65 in oled, speed, (254,64) doesn't work, at least 66 and 67 didn't do it.
Can anyone advise a way to access the 3rd and 4th rows in graphic mode?
