With the new robobrick under development using the atmel chip I started looking at the specsheet for the AT90USB1287 and comparing it to the PIC16F877 (the...
... In general, for roboticists, the choice between Atmel vs. PIC is made on issues unrelated to the chip architecture. For me, the cost of a programmer + C...
Having slept on it, here is what I think makes the most sense: Four assembly options, the matrix being: Processor 3.3V v. 5.0V. CAN4Bots v. RoboBricks2. ...
I'm at the checkplot/gerber review stage on a USBKEY breakout board as outlined below. My plan is to wrap up 3 or 4 other boards in the next 2 or 3 days and do...
If I want to learn how to program the atmel chips what development board / chip package should I order? Ease of use being a greater priority over cost. My...
Well, the "clean architecture" is to me less important than what having a clean architecture yields: C code that is easy to port from one AVR to another with a...
... I will continue to use the PIC16F688 for many of the RoboBrick2 modules that I design. The '688is a PIC in a 14-pin DIP socket that has no AVR counterpart...
Dave: Could you sign me up for a Rev. A board? My goal is to be sure that there are 2 or 3 of these things lying around in the RoboBricks2 community. Getting...
... Yes, will do. ... I'm just trying to set clear expectations. ... Yes, I'm doing a similar layering. Working bottom up: 1) CAN electrical and CAN framing...
Alan: Please read the schematic for the Controller28 Rev D: <http://gramlich.net/projects/rb2/controller28/rev_d/controller28.png> The labels on the left are...
Hi Wayne, Very interesting! I don't know if I would have gone to all that trouble, but it's a useful solution. I've often wanted a 'bot board that could...
... For *this* Atmel. For *most* Atmel. Not *all* Atmel. That's a common pitfall -- a few use other pins. ... Well, no. MISO -- Master IN Slave OUT is an...
Hi Wayne and all, I have a Shaft2 Rev D module I am looking to use. The connector to the encoder has five pins (Ground, Index, A Channel, +5 Volts, B...
... Some encoders have an index pulse that triggers once for each revolution. This is used to "home" the encoder to a specific angle. Most of the encoders we...
... [snip] ... This was my guess. It is good to get confirmation. ... Great. I'll bring my bot and shaft2 module to the next meeting. thanks, -Brandon...
The AT90USBKEY carrier board arrived yesterday. I haven't had a chance to do anything but open the envelope. I'll put together a package of schematic and...
Dave: I'm not going to make it to the Maker Faire, since my son wants to study for his three AP exams next week. When I look at all of the stuff I am trying to...
Hi, The board is 4 in^2, so that is a straight $10 at BatchPCB prices. Don't worry about mailing a check -- I'll catch up with you at the HBRC meeting. I...
Dave: I forgot to order a USBKey with my last DigiKey order, so do not rush to document on my account. Please hit me up for the $10 at the next HBRC meeting. ...
Well Dave, this got to me so I suppose the forum still exists. It has been pretty dormant for some time however. Bill Dave Curtis wrote: Is this list still...
... Yup. I was just going through my .procmailrc today and wondered if it was still worth having a filter rule. That's the only reason I remembered its...
Dave: As near as I can tell, the only people that use RoboBricks2 on a regular basis are myself and Bill Benson. We get together on a weekly basis, so we tend...
Brandon: I forgot about Mappy! I'm sorry. Also, I almost got Bob Allen to put a RoboBricks2 connector on the latest Trinity Fire fighting board, but he...
