Very nice programming. Looks great.

Well all you have to do is look and look again. I went back to the sparfun discussion of this board and someone by the name of "siren" has posted a link to his work. His code is a improved version of the original and it seams to work extreamly well. A link to his work is

Great work Siren.

I'ved done a lot of playing with the sparkfun code and had no luck with it as has anyone else as far as I have seen posted (here or sparkfun). It's not an easy thing this RDS. I was able to get callsign data out from the sparkfun code with a bit of playing. Glad to see the code posted by Si above.

Back to the drawing board for me I guess.

Take care all.

Hmmmm. That was a bit of a teaser. Is the station callsign as far as your code has got? Did you leave the rest for homework? Hope more is to follow or did I miss something?

Kevin

Thanks very much for posting your work. Looking forward to trying this when I get home from my day job.

Take care,

Yep... Works so much better now.

Take care,

LOL. That is what happened to me.... Playing with the Arduino in-between laying down ceramic tile on the basement floor isn't always a good idea... The floor looks good but the display was blank. While reading the library I thought it odd that it kept on talking about hundreds of leds... I bet it will work better when I put the right software in...

Thanks for the heads up.

Thanks for the info... I'll look elsewhere for the problem.

I have the new 2.8" 18-bit color TFT LCD with touchscreen breakout board from adafruit. The example software uses the arduino duemilanove and of course I have something just that little bit different. I'm trying to use the UNO.

Has anyone been able to get the UNO working with this display? Here is the demo software:

Thanks,

If your stepper motor draws a lot of current, and many do, you might cause the arduino to crash when the voltage drops. And the voltage will drop, it is just a matter of how much. Some things that will help a lot is keeping the power leads short and twisting them together if you can. Use power leads that are as thick as practical. Leads that are too thing will increase the voltage drop. Adding capacitors across the input to the arduino will also help.

If your stepper motor is large and you have a heavy load on it it will make this problem worse.

Works with my UNO on Windows 7 64bit. IDE is Arduino 22.

12  Forum 2005-2010 (read only) / Troubleshooting / Re: Xbee Wireless Sketch Upload on: December 14, 2010, 09:00:24 am
For me, using the latest FIO board with series one xbees, in a word no. It will work once, maybe a bunch of times in a row and then nothing I do will make it work. So yes it works but not all the time.

If I have a sketch loaded via xbee and then use the serial over xbee the pc can talk all day every day with the FIO/xbee sending lots of data at high speed. But try to upload a new sketch and it will time out.

Hitting the fio's reset sometimes helps if you do it at "just the right time" but not always. My setup is per ladyada, dio3 reset etc.

Now I wouldn't mind if you could not upload via xbee, if for some reason it wan't possible but when it says you can on the "marketing pages" I'd like to be able to do it...

I would love to see the testing that was done on the xbee/fio to demonstrate the sketch upload capability. But I think it was third hand info at best.

The jumper on the FIO has to do with the DTR and the xbee. It is a solder blob (technical term) on the pcb between the power switch and the battery connector.

I think there is a problem with the latest FIO and arduino021 with the series 1 xbee's reset method. I have the modems configured correctly and the jumper in place on the fio board and sparkfuns usb/xbee board. Sometimes I can upload to the board (via xbee) over and over and it works just fine. Then it will stop working and the only way it will reset is via a hard reset or power on off of the fio. If I were a betting man I would say its the cap on the reset line not being reliable...

In terminal mode the fio and computer talk perfectly together for ever.

MrFreeze

Thank you very much for the code and the time to answer. Very nice work!

Take care and enjoy the weekend.
