B4J Question 74HC595N in series with B4J

[Mark Read]

Could someone give me a start help on how to address two chips in series connected to a RPi. I am starting a new project: 3 x 3 x 3 LED Cube.

My plan: 3 GPIO for SER, SCK and RCK + 3 GPIO to drive the layers via transistors.

If I can get this to work, I would like to make a larger cube.

Many thanks.

You only need to cascade the chips.
See this example:

Good luck.

This is with B4R but it is should be easy to modify to RPi and B4J https://www.b4x.com/android/forum/t...gister-for-multiple-output.71531/#post-454790

I have also made a small tool in b4j to select pixels and colors and to create the byte arrays, then all is left to do is paste it to the b4r app.

Thank you both for your replies. I will look into both of them.
