31  Forum 2005-2010 (read only) / Development / SparkFun Seial LCD with NewSoftSerial on: June 23, 2009, 01:51:07 am
Hi,

I have found a need to use NewSoftSerial with the library for the SparkFun serial LCDs. I thought it would be as easy as replacing every "SoftwareSerial" wirth "NewSoftSerial", but I get a message saying the lib can't be built, "error: type 'NewSoftSerial' is not a direct base of 'sf_LCD' ". What am I doing wrong, or what have others done to use NewSoft on these LCDs?

Den er grei. Det finnes egentlig ikke noen standard pakke for dette utenom det jeg nevnte. For xbee trenger du arduino, xbee shield, xbee explorer usb (til pc), ir receiver og en motstand (mener det er 10 kOhm). Du får alt det på sparkfun.com. Jeg regner med at strømmåleren din sender ir-pulser, det gjør i alle fall min.
Du kan evt koble arduino direkte til usb hvis de er i nærheten av hverandre, da sparer du noen kroner.

Det er fullt mulig, og jeg holder akkurat på med noe av det samme. Men du trenger ikke pc. Jeg leser av og teller blink, regner ut strømforbruket på arduino og sender det til pachube (for logging og grafing). Sjekk openenergymonitor(.com?). Da trenger du en ir-mottaker (selges i par som sender og mottaker på sparkfun), noen motstander, en arduino og ethernet shield (også sparkfun) og en real time clock med tilhørende komponenter (elfa.se). Send meg en pm, så skal jeg sende deg koden (jeg har ikke fått sjekket den ennå, men det virket når jeg brukte ct som i energymonitor).
Men for all del, hvis du er mer komfortabel med programmering på pc, er det enkelt å telle et antall pulser for så og sende det til pc og gjøre resten der.

Google for atoi, riktignok fra string til int, men det funker, så kan du se andre varianter derfra

Bonsoir KilliYabb!

Oui, le Vin est "Voltage In", il est donc connecte au plug voltage externe.

Hi all,

Mind if I join in?

When you talk about separate supply and servos and motors, do you mean a separate power source, ie two batteries, or will one source like a big 12V battery directly and via a voltage regulator do? When a large consumer is draining from the battery, will the voltage drop in the regulated circuit?

Thanks Grumpy,

Aha, is that because the 328 is programmed as an arduino and used as a lilypad? Is that why the serial output is garbled?

Hi again all,

I have made an arduino clone at 5v, and have run out of 16mhz resonators, so I picked a 8mhz one instead. I can program it, the sketch seems to work, except I get garbled serial output. Can this be related to the frequency and voltage? I have programmed it as a lilypad, since it's 8mhz, but does the voltage interfere here?

Neither of the two. You'll need some sort of smoothing, since the pwm signal is on-off-on-off. Check out GrumpyMike's website: http://www.thebox.myzen.co.uk/Tutorial/PWM.html

I'm not sure the 328 in the arduinos are 328p's. have you tried installing the bootloader from avrdude? I hav to do that (including lockbits and fuses) on my custom made board with 168p because the signature is different than 168. -F will do the trick, otherwise the chips should work similarly.

1: I wouldn't know, since the chip is blank

2: Since the board sits in a nunchuck, I would like to be able to program it via xbee. The isp should still be able to reset the chip.

I have checked the soldering over and over again. My suspicion goes to the resonator, but I do not have a scope to test it.

Hi all,

I've made a miniscule board to put in a wii nunchuck and send info over xbee. To make it small, I've used the smd version of the 168, which does not have the bootloader. So I've made an isp plug in the board. Problem is, it doesn't respond. The programmer communicates with the 2009, so there's something wrong in my setup. Anyone have an idea what's wrong?

43  Forum 2005-2010 (read only) / Troubleshooting / How to improve xbee range? on: November 17, 2009, 03:57:09 am
Hi all,

I have made a Wii nunchuck wireless by xbee, and one of the applications is a garage door opener. It all works, but the range is terrible. The receiver part is inside a plastic enlosure on the wall in the garage, and I am trying to use the nunchuck from my car. Both xbees are series 1, 1mW. They should be a few hundred meters in open air, but I can barely open the garage from outside the garage door, and certainly not from inside the car. I have to walk out to 1-2 m from the door and hope it opens. Any ideas on how to extend the range? I have not seen any series 1 xbees with more than 1mW, and the battery in the nunchuck is only 100mA.

BLK is black and GRN is green, the colors of the ftdi usb cables used.
I wondered a bit about that myself.
