y-axis point resolution scrolling and character positioning #21

Closed jgrulich closed 4 years ago

jgrulich commented 4 years ago

I've found this lib very useful and now hit one limitation with y-axis. It's done for line of 8 points. But for smooth vertical scrolling is needed to use point resolution, same as is used for horizontal one. The same story it is, when I need to place some character at exact x,y position. I've tried to look around the code, but not able to locate the right direction. Please be so kind and help.

Thanks for letting me know you find it useful. The limitation on Y coordinate placement has to do with the memory layout of the OLED. For simplicity, the font functions draw only on byte boundaries. If you would like finer vertical scrolling, take a look at the oledScrollBuffer() function.
