wired up

 

Note green LED(yes it's set up in the correct orientation and even when I hook up a vmeter I don't see a voltage) is not lit up.(red is power indicator) I feel like amature hour here with this simple circuit yet can't seem to get it to work. Tried 2 different chips. Recommendations are welcome...I only spent this morning looking at it....

Heya LMR folks,

I'm thinking of having a G+ hangout session tomorrow around 10am pst(I'm in California), 1pm est, UTC -7(I think).

If you want a gmail invite, send me a request by 9:45am and I'll send in invite your way and have a gmail account I can send it to.

I was thinking of just shooting the breeze, talking about bots, projects, and just general stuff.

maybe it'll be something, maybe it'll be just me some ambient noise....we'll see!  :)

 

Edit: modified time.

Just a note that this is a pretty sweet device and worth it for the price. Hell, the launchpad alone is worth the price considering it's utiility and fun aspect. I picked up two of these and just played around with the default app, when I have more time, hoping to make it useful and do stuff(control motor speed or something like that.)

How to use HPWM for picaxe chips.

By voodoobot

This information is based on the chip that is used for the 20x2(PIC18F14K22) To get a better understanding of the modes, I suggest referencing this datasheet for further information on the chips features. IMages and info are referenced from both the picaxe 2 manual and the PIC datasheet for the above mentioned chip.

HPWM, what is it?
