24x6 matrix problem.

Hi, can anyone explain to me in detail the code of void display_word, finish_scroll, byte make_word,void latchOn(), void latchOFF(),and where we take data sent by SPI. In pdf file there is a code and a scheme.


I want to create a program that displays temperature and humidity as variables are taken from sensors.

I will take a look when you post the code here.

I can’t post it because the code is too long.

Jikata: I can't post it because a code is to long.

You can add it as an attachment.

This is a code with scheme

The reason that we ask for code to be posted or attached is to allow it to be copied into an editor for examination. Attaching a PDF makes this more difficult so you are likely to get less help.

Ok, I will do it that way.
In byte dummy_word we use |= (OR) to increase 1 last bit and then use << to move bits in left.

Hi, What is the application? What is your code for? What is it not doing? Did you write/develop this code?

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf?

Thanks.. Tom... :)

I did 24x6 matrix , which receives data from serial port. Now I want the same text to spin :(Temperature is (variable) Humidity is: (variable), as variable are taken from sensors.
The code is taken from www.instructables.com/id/Make-a-24X6-LED-matrix/step2/How-it-works/
