8 Digit Dot Matrix Module component for MAX7219

Postby MJU » Sat May 30, 2015 11:43 pm

Hi there,

I've been looking on this forum for Flowcode components that drive 8*8 dot led displays.

These displays are very very cheap and even the modules that have a MAX7219 driver IC on board are so cheap they are too good to be true. :-)
The existing FC LED DOT components use two SN74LV374APW chips to drive 16 LED's? (I can't even find them in DIL)
The helpfile for the serial/parallel doesn't show how to connect these IC's to a 8*8 dot display.
For testing purposes it's often more fun to have a ready made hardware board to play with, than first solder a demo-board yourself.

Is there any chance that there could be a Flowcode component to achieve the same as the current serial/parallel component?
I would love a component that could scroll a text up/down and so on (just like the current component).
This component should drive a MAX7219 which is often used for this purpose.

Thank you STibor!

I gave my display with a friend and as soon as he returns it I'm going to test your program!
I gave it because I need to read the datasheet thoroughly if I want to start playing with it.
Unfortunately my time is limited so it takes time.

You did a great job with the flowcode, it looks promising.
It is hard to read because there aren't much comments in the code.

I still hope that someone has time to create a component for this piece of hardware, that is the strength of Flowcode.

Hi there STibor.

The program works! Thank you, I've learned from it.
If some could make a component for this one it would be great! :D
