Seed Studio LED Stripe Driver with Photon

Firmware Libraries
1

Dear all,
I bought “Grove - LED Strip Driver” and thought that i could use the arduino library which is available from Seed.

After downloading from here: http://wiki.seeedstudio.com/wiki/File:LEDStripDriver_library.zip
and put the demo examples into webide I got error messages.

Who can check this?

Or can I use alternative Libs for an RGB Led Stripe?

What have you tried so far and what are your error messages?

Have you added the .cpp and .h files from the library into your project in Web IDE?
Make sure you only have one example in a project in Web IDE.

In theory, you should be able to get it to work, but it will take some effort.

If you want an alternate, you could try searching for libraries that work the for chip on the Driver board… there is at least one mentioned on this forum.

Yep, I added cpp and h-files into my procet in webide.

I set //#include Arduino.h in remark in the .h-file.

After verifiying the code I get this error:

I’m using an grove-shield and put the LED Driver on D4.
I suppose that with the pins definition of #define CLK 2 and #define DIO 3 has to do.


 #include "RGBdriver.h"
 #define CLK 2//pins definitions for the driver        
 #define DIO 3
 RGBdriver Driver(CLK,DIO);

 void setup()  
 { 
 }  

 void loop()  
 { 
  unsigned int i;
  while(1){
    for(i = 0;i < 256;i ++)
    {
    Driver.begin(); // begin
    Driver.SetColor(0,0,i); //Blue. First node data. SetColor(R,G,B)
    Driver.end();
    delay(10);
    }
    for(i = 255;i > 0;i --)
    {
      Driver.begin(); // begin
      Driver.SetColor(0,0,i); //Blue. first node data
      Driver.end();
      delay(10);
    }
  }
 }

I found an alternate with searching for P9813-chip and execute the example.
Nothing happens - lol.

The example defines a clk_pin, data_pin and number of leds:
´´´´
// define NUM_LEDS 1
// P9813 leds(D4, D5, NUM_LEDS);

In my circuit I´m using D4 for LED Strip Driver and D6 for an button to swich on.
What is to change that it works?

Change this line to:

#include "Particle.h"

That will fix the errors you are having.

Thx Rob! You are right!

Code works, BUT cant control the light strip.

I dont know how I can define that the LED driver is on D4 (have a button on D6 on my grove shield)?
At the moment the power circle is closed and light is shining (but I havent control over the driver to put on/off with button).

´´
// #define CLK 2//pins definitions for the driver
// #define DIO 3

Dear Community,
I solved it with Arduino Uno, Grove Base Shield and Grove LED Strip Driver and documented it here: MyPIR Sensor activate analog RGB Stripe
Thx for support!
