BlinkM Datasheet - You want page 17. Ignore the messy, nasty, arduino code.
Examples; (I'm taking a break from mind numbingly boring work)
Code:
Just some examples, now they are untested but I had positive feedback with the red light code the other day so assume all others will work. Hopefully it is enough for you to see how to carry out the functions described in the datasheet since this is no arduino you're using so their code is near useless.
GREAT Presentation Rich !
Thank You for the introduction to BlinkM & It's Datahheet.
Do I add a secong EZB?
If I script it as in the post above what language do I choose?
JUst not sure how to tell address each device (one differently then the other)
Use
Code:
to change the address of the first one (without the second being connected). That will change it's address from 0x09 to 0x0a. You can change the 0x0a to anything you want provided it doesn't clash with a different I2C device.
Probably easiest to open the script console (under script) in ARC and manually type the above command in once. Then you can close the console and add the second BlinkM.
Once that command has been run it should be re-addressed. Then use the I2C control, change the address in the box at the top of the control and move the sliders to change colour.
Or write scripts to trigger specific colours for different actions etc.
From the datasheet:
3.1.1 I2C Addresses The default BlinkM address is 0x09. It can be changed at any time with the "Set Address"("A") command described below. BlinkM responds to both its defined I2C address and the "general call" broadcast address (0x00).
Building on Rich's code it would be:
Code:
Oh yeah when I was tinkering around with them using the built in pulsing of brightness and color they do fall out of sync. If I remember correctly there was a way to one to be the master timer. It's late here and I need sleep. Rich, can you find and post the correct code for it?
One more hint, the I2C codes are case sensitive, i.e. I2CWrite(0,0x09,A,0x0a) would be different to I2CWrite(0,0x09,a,0x0a). Pre-empting a few questions and problems
BlinkM Example Script - The good news is my first assumptions were correct and all previous scripts and posts I made are 100% accurate
Expect to see this in Melvin's head soon... until then, I have a video which I will pop up later.
