Re: [time-nuts] IRIG-B with Arduino
And don't forget the AtMega88 - not as much memory but you can still pack a lot into it. I think the original Arduino was based on the 88 and the bootloader is still available meaning you can build an Arduino compatible board using the 88, you may still be able to by the 88 chip with the bootloader already programmed from some of the online arduino suppliers i.e. Adafruit http://www.adafruit.com/ among the many others (and eBay too).

[time-nuts] IRIG-B with Arduino
If you didn´t started yet, you may consider the PSoC series of Cypress semiconductors. They contain digital and analog resources within the chip, simplifying the hardware design – and hardware changes. The new design, PsoC 5, is based on the ARM architecture, up to 256KB code and 64kB data, support for USB, the usual peripherals plus PLDs, OpAmps, and other analog devices. The starter kit is very affordable (US$48.88 on DigiKey). A version is planned in 48 pins SSOP – soldering is not as easy as dip, but doable. Even the 100 pin TQFP is solderable – QFN is another story… -- Geraldo Lino de Campos gera...@decampos.net ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.

Re: [time-nuts] IRIG-B with Arduino
Loks like I need to make myself clear also. Sorry. When I said develop on the desktop I meant for a desktop target.

The best way to learn programming in C is to do so by writing for a simple and easy to use target execution environment.

[time-nuts] IRIG-B with Arduino
Fellow clock-tickers, I'm finally starting to learn microcontrollers, and have selected Atmel's AVR line as my tool of choice. I've also discovered the Arduino site, and am starting to learn their IDE as well. My first goal will be an open-source/open-hardware IRIG-B decoder (takes IRIG-B 1kHz stream, sends the timecode to an LCD panel). I've noticed a distinct lack of hobby-priced decoders on the market, and I intend to try and remedy that. My initial development platform will be the Arduino Mega-2560 board. However, that particular microcontroller is unlikely to be my final chip of choice due to the fact it's not available in a hobbyist-friendly DIP package. If others with more development skill have suggestions for a different chip, I will gladly listen. Stay tuned for further developments (no pun intended).

Re: [time-nuts] IRIG-B with Arduino
Bruce: You may not need the Mega. I started with the arduino in duemilanuove, and found that there are chips with the bootloader available. The IDE is actually pretty good, not too steep, and there are libraries available for lots of peripherals and lots of sample code. I suggest Sparkfun as a source, I have had very satisfactory dealings with them. The Due also has piggyback boards called, for some unknown reason shields, which make the construction of small systems very easy.

Re: [time-nuts] IRIG-B with Arduino
If the goal is to learn about AVRs that is a good project. But if you want a cheap IRIG decoder I bet you already have one. An IRIG driver is included with NTP. The NTP driver reads the time code from an audio interface set for 8Khz sample rate.If you are writing a decoder it might be good to study the NTP source code. They do good bit of error checking and averaging and get to microsecond level even on noisy signals. But then it runs on an full size 32 or 64 bit computer There is also an irig time code generator in the source .tar file but it is not compiled by the Makefile, yu have to do that by hand. No the IRIG driver is compiled by default On Tue, Dec 14, 2010 at 10:19 PM, Bruce Lane kyr...@bluefeathertech.com wrote: Fellow clock-tickers, I'm finally starting to learn microcontrollers, and have selected Atmel's AVR line as my tool of choice.
