Hurray for ssd1306_bitmaps() #19
Comments
I accepted your suggestion and changed the unit of the width parameter from bytes to pixels. However, width only supports multiples of 8.
Thank you for your suggestion. |
thanks

I found that ssd1306_bitmaps can't be drawn too quickly. https://github.com/nopnop2002/esp-idf-ssd1306/tree/master/AnimationDemo |
Will look, but I couldn't use the bitmaps, because they clear the screen.
I resorted back to displaying a 16x8 bitmap using two character bitmaps.
Cheers,
/c

Noticed you run SPI_CLK at 1 MHz. Surprised you need short wires. Remember seeing it should go up to 8 or 10 MHz. |
I tried it at a frequency of 2M but it didn't draw correctly in my module. |
Thanks for the bitmaps function. I am using it!
Just ran into something that could use some attention.
In the new function
The
xpos
,ypos
andheight
parameters are in pixels. I suggest either changing the parameterwidth
to mean width in pixels, or renaming it so that it is clear that it is pixels/8.Also, the
ImageDemo
example callsIt passes the height as
12
, but the image in the arraybatman[]
is 13 pixels heigh./Coert
