Re: Dreaded newb Q: - RBBB+BUBstk500_getsync(): not in sync

Hi folks, I recently took delivery of a batch of 5 RBBBS. I put the first one together seemingly without incident (besides a couple of minor scorch marks on the tracks before I realised my iron temp was too high), fired it up, got pilot light, did the LED on 13, got flashing light, then ran into st...

Re: GLCD Fun

slows down the code by having to do SBI/CBI instructions for every single bit For flexibility I have decided not to try to keep the data bits on a single port any more. I just write my code to set the bits individually using SBI/CBI all the time. For the worst case it takes 6 clock cycles to set up...

Re: GLCD Fun

Don, That's Very Cool. One thing I did differently was to skip over the Tx/Rx (D0 & D1) to allow use of the serial port concurrently with the GLCD. That's why I had to have 2 wires going over to the analog pins. The analog pins are for DI and RESET. All the other pins were run straight across. The u...

Re: Uploading under Ubuntu

As an alternative you can add yourself to the "dialout" group.
This will allow you to open the port as you without having to promote the IDE or avrdude to root.

Re: small updates for next BBB PCB.

When I decided to include inductor I looked around for a small unit and also the right price and didn't find any through-hole parts that fit the bill. I understand, as this is a cost sensitive product. But perhaps it could be an order option where you charge say an extra $1.00 for those that want t...

small updates for next BBB PCB.

Paul, I have to say I love the BBB board. From the nice light PCB color with the easy to read labels to its ease of use for prototyping. If you ever do respin the BBB board for some reason, here are a few tiny things that perhaps might be worth considering. - Make ISP power line larger In some cases...

Re: Arduino newbie — failing to upload sketch

On the Rev E board I have, it is a bit confusing. The RX & TX lines on the 6 pin serial connector are from the remote end's or cable's point of view vs the BBB. So the BBB will transmit on the 6 pin header pin labled RX and receive on the pin labled TX. However, on the breadboard connections, they a...

Re: v-usb boot loaders mega168 compatible

Paul, I've seen sample projects with the V-usb/USBTiny stuff working on ATtiny45s with no crystal. Really nice for that environment as you can get a full USB serial connection to the host using the serial CDC without needing any additional USB->serial hardware. So it definitely could work on somethi...

Re: GLCD Fun

What makes it so neat/simple electrically is that of the 20 connections to the GLCD, 14 of them can be passed straight through to the BBB board. The actual GLCD I bought locally here in Dallas at a surplus shop called Tanner Electronics. http://www.tannerelectronics.com/ But they are also available ...

GLCD Fun

Spent the past few days "gluing" a cheap GLCD ($8.95) to a BBB board. I thought about a text only 44780 but thought why not go all the way with a GLCD instead. Took quite a bit of effort to straighten out the GLCD low level s/w. None of the existing ks0107/ks0108 GLCD or even 44780 text LCD s/w exam...

Re: BBB pin overlay card for non Arduino users

It printed out just a little large on my ancient HP-4P but still quite usable. Don This sounds like the problem I had with scaling. Even on my machine, Open Office and Adobe Reader on Vista didn't print the template the same. Maybe you could help me resolve this. What OS and application are you usi...

Re: BBB pin overlay card for non Arduino users

So here is a first pass at a pin overlay card. Turns out it is quite a bit more difficult than you would think. The problem is that different components render slightly differently. So the exact image printed directly from OpenOffice Draw prints at a slightly different scale than when Adobe prints t...

Re: BUB board

It can definitely be done. All the hard parts like s/w support have already been done. There are a few other boards out there already that use "DASA" style bit banging across the USB bus with FTDI chips. I'm surprised that more people are not taking advantage of this capability yet. The latest USB A...

Re: BUB board

I did the testing on a Vista machine with the "raw" board. i.e. not even a connector was soldered in yet. From what I've seen, it is definitely the way the FT232R is configured. It seems to have all the factory defaults which makes the CBUS1 pin a RX LED indicator. I downloaded and ran MPROG and cha...

Paul, The BUB board web page mentions that is has: An LED which shows serial activity on both the TX and RX lines My board only blinks the LED on RX data. No blinks on TX data. The board appears to have the LED wired to CBUS1 which can be configured in the FTDI chip EEPROM to blink on both RX and TX...

Re: BBB pin overlay card for non Arduino users

Well, I've played a bit with creating a BBB overlay "card". NOTE: The analog labels actually do line up properly. The overlay is curling up so the the overlay is not flush with the BBB board. It is definitely doable but the space for labels is very limited. I'll go ahead and finish up an overlay car...
