Arduino/Duinotech 8X8 Led Matrix

Hi, I'm new to Ez Robot and new to this forum.

Here in Australia, we have a electronics suppler called Jaycar who supply an Arduino equivalent called " Duinotech"

My question is: Can you use Arduino/Duinotech 8x8 led matrix with the ezb4 and how, as the Duinotech 8x8 has 5 pins

VCC
GND
DIN
CS
CLK

Protocol is SPI ( Shift-Register )
Chipset is MAX7219
Led colour is Red

Could someone help me please with how to connect the pins to the ezb4, and how to add it to ez builder.

Sorry for the dumb question

Many thanks
Steve

Looks like it's i2c. Check the datasheet and use the i2cwrite commands from ARC. It'll be easy:)

Have you read the datasheet yet?

If I were you, I'd wait for the ezrobot rgb8x8 because it's supported directly.

Hi Dj,

tthanks for responding

All Jaycar provides is the following

"A 64 Red LED matrix, this module is easily controlled with the Led Control library. Display your own custom characters, or use multiple modules together to make a scrolling display.

Operating Voltage: 5VDC
Protocol: SPI (Shift-Register)
Chipset: MAX7219
LED Colour: RED
Dimensions: 62(W) x 32(H) x 14(D)mm"

so not a lot of info, only that it is suppose to be the same as the Arduino equivalent?


Can you help me with what pins to attach to which on the ezb4?

That is not enough information. A datasheet will explain what commands that the display requires. You will have to find a datasheet.

As for connecting it to the ezb. It's i2c. So you will need to connect it to one of the three i2c ports.

I'll warn you now - that product does not look very easy to use.

If you do, consult us here by seeing if they have a datasheet.

Have you seen the ez-robot rgb 8x8 display? It's way cooler anyway - and it's RGB which means color:)

It will be on this website for purchase in about 1.5-2 months. You can see a preview of it in the friday the 13th video that i did a while ago

It's way cooler:D

Yep, that looks great.

I'll will certainly be getting that.
By the way, i'm new to ez robot and I just love it.

Im having a great time just experimenting around with it.

Thank for such a great product.
