SSD1306 OLED (72x40) I2C display from scratch

[richard]

link worked.


all you need to do now is
1 create a 14x10 font with the chrs you need
2 workout an efficient way to store and retrieve the font
3 develop a nice way to plonk it on the screen

easy as pie
ps
if you only need numbers and "%" ,"." it could fit on a 16f690 easily




hint , pic16 flash memory is 14 bits wide, the ssd1306 can fill memory in vertical mode too

Thank you so much Richard!!!

I'll give it a try to create a super big font.

Let you know for any progress in the next days

something to consider about fonts
it looks like you want 40x22 size font
a pic16 has a flash word size of 14 bits therefore a font that size
will take if encoded horizontally by row take 2x40 words per chr
it will take 3x22 words if encoded vertically by column a reasonable saving.

one of the benefits of the ssd1306 controller is that it can address its graphics ram either way with ease

Richard,

I'm still trying to understand your previous post but just for now, there's a question burning my mind: how do I address the display pixel by pixel?
