Welcome! I bet you make kick ass smoothies I don't, my wife doesn't let me play with our blender. It doesn't work very well and she is scared that I will mod it.
-
Can you record it for those not able to be there on the 23rd? Like a screen cast?
-
I didn't know they made PCBs
-
I like your analogies

Can't flash the MSP430 with Launchpad - stuck at step 0 :(
JMLB replied to schweini's topic in Development Kits
just curiosity, Those(like me) that have to unplug and replug your launch pad, what os are you using. Windows here. -
I am building a robot similar to this. I have dedicated UC controlling the motors, sensors and displays (to be implemented). they then communicate with a brain with a can bus using a chip from Microchip. I forget the number but you can communicate to it usin SPI

some times I got to plug and unplug mine cause it just stop detecting. I don't remember the error it gives me -
Thanks for that. I was just guessing. Ill do some of that reading lol
-
They are trying to implement boost in the standard C++2. so it should be portable
-
Thanks! I don't know why, for some reason I had drawn VCC -> resistor -> reset pin -> ground. I am not sure why I did that lol. the cap would be to start from gnd and slowly bring it to vcc?
-
wouldn't that bring my reset pin to ground? would a voltage divider with a small resistor and VCC and a large one on the ground work?
-
the punch cards concept is still used if you think about it. When you need to darken the circles on a survey (using only an HB pencil). My high school use that to take attendance. one of my friends, from high school, wrote a software for it to generate a hex file for a motorola chip
-
how would you tie the reset pin if you wanted to be able to reprogram it in the field?
-
cant you just put break points and view the variable state? that is how I do it
-
I did think og using a lieter pot rather than a rotary pot and have the user slide it up even with the stack. I think RobG's Idea with the LED might be a good Idea LED are cheap and I can find them every where
-
I do like the ping idea though the distance meeter usualy have a minimum distance. I also don't know if its accurate enough to detect the difference of 1/4 inch? I might try it though and see. I also don't quite understand what you mean with the sensors being diagonally? can you explain a little more? thanks
-
after reading some more, you are right, they measure the change in pressure. Thanks. i was hopping not to use presure sensors since they are expensive. But I guess its the best way.
-
that is sorta what I am trying to accomplish with the piezo. I have a piezo at hand and they are cheap. any link for a pressure sensor?
-
I am trying to find a way to measure how many poker chips in a stack. My though was to put a peizo and put your stack on that. I don't know enough about peizo though. Any thoughts would be appreciated or if you would use some thing else.
-
I mean is cost money for badwith time hosting hard ware and prizes for POM. I am all for adds
-
If it bring money in to the forum I won't mind it. as long as its not the adds that hilight words and open when you mouse over. I hate those. I don't even read the site
-
TP3 will give you 5V if not TP1 will I can't remember. I solder a socket so I can use it when ever I want. (provided by gatesphere)

naw its a M430 not MSP. I think it might be a msp430 with the program all ready loaded. if you google M430F449 you will get distributors calling it a multimeter chip. I got 117 quotes this morning after posting I wanted the datasheet. none gave me the data sheet lol. I also got like 20000 msn requests. This might have been a bad Idea. luckily the msn was a scrap msn that I use for occasions like this
-
the fluke 87 seem to be using a TI multimeter chip. m430f449 I can't find the data sheet though. I sent an email to a supplier. we will wait and see.
