[sisco1]

Hi can somebody help for 8x8 led matrix HT16k33?
Write simple program with scroling text,on simulation work perfectly,on bredboard it work only on half of led matrix (left side),right side not work.
Any help is welcome

You tried then all?
If 8x8 does not work,
Then try 16x8 or 8x16 instead.
Even though you have 8x8.

Ok on 8x16 it work,can see full scroling text on matrix,but on hardware text is raised upper by one position the top row is visible below.
when I select row 0 and column 0 LED, a second LED from the first column lights up.
how can the text be cut down one row below?
On simulation work ok.

Hi Benj here program,on simulation its ok,but on hardware its start always from second line,when scroll text,upper line is visibile down on first line.

I know i'm off topic but... forgive me.
Just a question.
There is a way to discard, i mean uninitializing, the macro component witout resetting the micro? Arduino atmega328p is my platform.
I need that the micro keeps running also if the I2C HT16K33 gets stuck in any event. Now, if just a pin gets interupted, the program hangs up and stops. There is a way to avoid this problem?
