problem with I2C Bicolor LED matrix

[peebeeke]

Hi there,

when I try to draw a line from 0,0 to 8,8, i get strange things on the bicolor led display, and if I set the 0,0 pixel on the matrix,
instead of setting the pixel in the left corner, it sets the pixel somewhere in the middle...
Am I doing something wrong here? I use the gfx and led backpack libs, when I perform a fillscreen everything works perfect
but it seems like the top row, column pixel is in the middle of the led matrix instead of the left up corner.

anyone also had this problem?

Post a photo of your soldering - and the code you are using.

Take a look at this page, I wrote up a (reminder) page for myself since the documentation isn't realy clear on it.

check the bottom part of the page on all the pins, Columns and Rows, this might help you with your problem.
