Problem there is you're tied to only one board house, isn't it? I use a variety and also do contract work that requires my customer use their own houses too. Appreciate the input, though. REB stevech wrote: >I gave Eagle several evenings. It was just too user unfriendly for me, g

As I understand the history, CircuitMaker was a schematic capture and circuit simulation program designed for the Mac. Protel designed Autotrax for DOS and ultimately sold this to Matt and company...they renamed it TraxMaker and brought it into the world of Windows when they did

Thanks Ken. It appears that there have been some changes since I looked at it last, which was quite some time ago. And this brings up some questions: 1. Are symbols only available in ISO standard or are ANSI libraries also available? 2. I see a lot of export and import file forma

I gave Eagle several evenings. It was just too user unfriendly for me, given I would use it infrequently and forget the 10e99 nuances that it has. For quickies, I like ExpressPCB. Limited but you can learn it in a half hour. _____ From: AVR-Chat@yahoogroups.com [mailto:AVR-Chat@y

David - Crystals and capacitors work this way: The two caps appear in series ACROSS the cap, and two equal caps in series have a net value that is one-half either. But, looking into the IC, there is a stray capacitance of about 5pf. So, if the crystal wants a load capacitance of

The way atmel did the fuses is a bit confusing, and that may be what's going on. One thing to check that I didn't see mentioned, is that CKOPT needs to be changed. The default state enables a low power "vittoz mode" oscillator that may or may not run with a given crystal, or wors

Hi Folks, What is the most popular method/device for working up a prototype using the tiny13 chip? I have the STK500. Is this good enough? How about using the debugWIRE? What works with that? Should I hold out for a Dragon? Digi-key lists a ship date of 9/15/06 but that might be
2006-09-12 by kernels_nz
Hi Guys, The Tiny13 cannot use an external crystal or ceramic resonator. The only way of getting an accurate clock is an external oscillator into the CLKI pin. This would require building a oscillator around a crystal. It really looks like the better long run option would be to e

I have used that approach to decode RC5 frames from an IR receiver on a Tiny11 running with the 1.2MHz internal oscillator. Worked 100%. Mark Jordan On 12 Sep 2006 at 15:59, Larry Barello wrote: > Look for ceramic resonators with built in capacitors (three terminal > devices) at
2006-09-12 by Larry Barello
Look for ceramic resonators with built in capacitors (three terminal devices) at digikey. They work pretty well. It seems with a little thought that the pulses could be discriminated using the internal oscillator. Use the first pulse to "calibrate" the clock with upper and lower
2006-09-12 by Richard Cooke
Hi Mark, So basically I would start the timer when the first pulse comes in stop it when it goes low. That will give me a rough idea how many timer "ticks" elasped for the first 2000us pulse. I then use that value for the rest of the pulses. I'm not familar with RC5 but I'm happy

Thanks Larry. That's a good idea and as soon as Jameco coughs up my '13 chips I give that a try. --- In AVR-Chat@yahoogroups.com, "Larry Barello" wrote: > > Look for ceramic resonators with built in capacitors (three terminal > devices) at digikey. They work pretty well. > > It s
2006-09-12 by David VanHorn
The internal timer isn't that accurate over temperature. You might be able to get away with something like this: Sit in a loop, waiting for something. Pulse detected. Wait about 3/4 of the delay, a pulse in here fails. Wait about 1/2 the delay, no-pulse in here fails. Resync on e
2006-09-12 by Richard Cooke
Thanks for the info. I've looked at the ATtiny13 datasheet and I'm a bit confused on how you'd connect an external crystal. On the Attiny11 and 12 you sacrifice 2 pins to use the crystal (PB3 & PB4). How does that connect to the '13? I haven't used a ceramic resonator before - ca
2006-09-12 by Richard Cooke
Hi Folks, I'm just starting this project where I'd like to use an ATtiny13 (for cost and size reasons) to monitor an IR receiver chip. When the processor sees three pulses it will energize a relay. I'll just have it sit in a loop waiting for the first pulse. The 1st pulse is 2000

I don't think your shifting of data in does what you want it to do... I would guess it always returns 0xFF00 or maybe 0x7F80 change output |= (IR_PIN & 0x80); to if (IR_PIN & _BV(7)) output |= 0x01; Cheers!
