Hi Yuriy.
I'm really impressed by the job you've done.
So much impressed that I have ordered Shahe scales and that I will build a MSP430 DRO controller.
I don't understand what is the use of the serial to USB adapter, as I read in various places that the MSP430 board can be connected directly to the computer (even running on Linux).
Can you tell me please if it's necessary to buy one or not.
Regards
Thierry

Thierry,
Android app doesn't have drivers for TI's USB chip, so you need a chip that it can work with. That said, I will be removing USB support in the near future, so I suggest that you use BlueTooth instead.

Ok.
That means I do not need it.
I guess that I can program the MSP430 directly from my computer (sorry for the maybe stupid question, but I don't know anything about programming a chip : I'm just a plug and play hobbyist).

Thierry,
Got it. I misunderstood your question.
You know that you can just buy a pre-built and pre-programmed controller board and skip the head ache of building, programming, testing, etc?
Regards
Yuriy
Yes, Yuriy, I know that there are prebuild boards, but I enjoy building by myself (and more of that it's less expensive)
I hope the building won't be too tricky and that it will work at first try.
I hope also that the next versions of TouchDRO will still be compatible with the MSP430 controllers.
If I understood all the article about DIY controller it's rather simple to build, no???

Thierry
It is a simple build, but make sure your soldering skills are tested before desoldering the header pins on the Launchpad. The pins for Vcc and GND are soldered in VERY well on that board. An alternative is to just use the pins and construct your own wires for connection to your scales using jumper wire kits from Sparkfun, etc.

Yuriy's boards are well laid out and compact, plus they've been exhaustively tested.
The fun of building this is incredible, but if you find yourself smashing your head into a wall, I'd suggest a kit. You still get the fun of soldering all the bits and pieces, but the desoldering "fun" is taken out of the equation.

And do not worry about compatibility with the MSP430. I do think it's Yuriy's favorite Wink
Thanks Eskimo.
I'm looking forward to build the controller and more of that to use the scales on my millng machine.
I've received the USB adapters ths morning... It's a beginning...

Hi everybody.
I've received and soldered my Launchpad to the breakboards.
It came with two chips : one MSP430G2553, and one MSP430G2452.
Which one should I use ? I would bet on the 2553...
It is written in the notice that the chip is already loaded with one or more programs. Do I have to delete them before loading TouchDRO ?
There is also a micro quartz in the box. What do I do with it ?
Last question : what about the jumpers on the board : P1.6, P1.8, VCC, TEST, RST, RXD, TXD ?
Regards
Thierry
You guessed right with the chip, the G2553 is the one you want.
The micro quartz is a watch crystal oscillator that can be soldered onto the Launchpad as an external clock source. You do NOT use it for this project. Also, it solders onto the same pins that the W axis uses.
When you Flash the firmware onto the chip, the old program will automatically be deleted.
Leave the jumpers the way you found them (i.e all jumpers connecting the emulation side to the MSP430G2 side), it will not affect the controller, and if you plan to power it from the USB plug, the Vcc jumper must be left in that configuration.

Whew, did I miss anything?
Thank you Brian.
All the jumpers are "on" (I mean in place), and following your advice I will leave them in place.
I plan to power the board from the USB plug, because I don't know how to do else (if there was another possibility I would not have to buy another phone charger, as I have a spare one but which has not a micro USB plug, but a jack plug).
Another question : the green LED indicates that the power is on ; what about the red LED ? Does it blink all the time (that's what it does at the moment).
And the last one (for today ) : are the push button of any use for the TouchDRO application ?
I really don't know anything in electronics...... and reading the documentation of the controller is just like reading chinese....
Regards.
Thierry
