It appears that he used a LaunchPad to program and then put the programmed chip into the circuit. The programming process is described here: http://43oh.com/2011/11/tutorial-to-use-your-launchpad-as-a-programmer/
The LaunchPad is not necessary for the circuit after programming since the circuit provides 3V3 power, external crystal, and the necessary passives.
Thanks for the quick and concise answer.
I've spent ages trying to find an answer and you've given me the very page I needed! I can start moving ahead again
Given I'm going to have to buy a Launchpad for this, I'll have to think of other ways to use it.
It seems the guy on the website regarding the clock used an MSP430 and the Texas Instrument LaunchPad to programme it before using it in his circuit so I
In addition to all the above, not to overload you with information...
Since the LaunchPad only cost $10 you could use it if you wanted and just remove the voltage regulator and G2211 microcontroller shown in his circuit. But then you wouldn't have that cool LaunchPad to play with anymore.
And a couple more suggestions/comments....
Let us know how it comes out....
I just don't see any reason for buying old MSP430G2 LP with not updatable firmware and limited support for 10$, when new MSP430F5529 LP based on eZ-FET Lite with updatable (open source) firmware can program all SBW devices for 13$.
An update and a cry for help!
Since the last post here, I've finished my scratch built CNC machine, controlled by the Arduino and it seems to be working fine. I need this to cut the gears for the clock. I managed the electronics because I simply followed other peoples Arduino projects.
However, I've not got my head around the electronics for controlling the clock, despite the friendly advice I've received. I'm really a wood builder rather than an electronics guy.
In the meantime I've emailed the original builder of the micro-controller circuit, hoping to buy a complete unit but it seems he doesn't offer them for sale.
So, my cry for help: Is there anything similar out there in the market place or could/would anyone be interested in quoting for a complete unit?
