blinkm

Dave Matthews

I am preparing to have some fun with the propeller and some blinkm LED arrays. I searched the OBEX and the forum and found some snippets and such, enough I'm sure to get started. But just in case someone has done more work than is available in the OBEX, I thought I would ask. I am looking for any specific blinkm routines that I can experiment with to enjoy tinkering over this long weekend!

Check out the propellar tutorial.there ae single cog and multicog examples blink a few times or forever.

Just got back to it, the BlinkM examples from 5 years ago work perfectly:

CON
 _clkmode = xtal1 + pll16x
 _xinfreq = 5_000_000
 
 'Physical Inputs
 i2cSCL = 17 '<<<<<<set your actual pins here
 i2cSDA = 18
OBJ
 i2c : "minimali2cdriver"
 
PUB Start
 i2c.i2cstart(i2cSCL)
 TES 'run the i2c method below
 repeat 'stay alive

PUB TES
 i2c.i2cstart(i2cSCL) 'start condition send SCL pin number
 i2c.i2cwrite(i2cSCL, %0001_0010) 'send address $09 plus write bit '0'
 i2c.i2cwrite(i2cSCL, "p") 'not sure here about this i2c driver sending 'f' as a ascii, may need to convert to hex first? someone comment
 i2c.i2cwrite(i2cSCL, $02)'value for red channel to $FF
 i2c.i2cwrite(i2cSCL, $00) 'value for blue channel to $00
 i2c.i2cwrite(i2cSCL, $00) 'value for green channel $00
 i2c.i2cstop(i2cSCL) 'stop condition

The BlinkM is a very cool part, and I will now start writing objects to use the part in spin. Thanks to all those who provided the code snippets way back then!
(The command characters such as 'p' for play and 'o' for stop are indeed entered as ascii.)
