Hey - there weren't any messages posted, so maybe this will be the first one? I've been following the RoboBricks2 stuff from a distance, and I'm definitely...
... first one? Yup. You got first post. I'm going to let a few more people who said that they were interested sign up before I start posting. ... I know you...
Hi Wayne, ... Sounds interesting. I'd be happy to review your schematics. I took a look at Rev C. So does the 16F767 have a CAN controller onboard? Or are you...
... RoboBricks2 uses CAN bus physical layer and UARTs. Since UART's are trivial to use, it is easy to develop the firmware for RoboBricks2 modules. Basically...
Hi Wayne, ... Ahhh. Somehow I managed to miss that little detail. The schematics make a bit more sense now :) I've done a few bootloaders for the ATMega as...
... Yes, I do and ... ... a protocol. ... there is a specified protocol. <http://gramlich.net/rb2/controller28/rev_c/index.html> has both the boot loader code...
... I've used the MCP2515 for a few projects with an atmel arm (their SAM7 series before the SAM7X with the onboard CAN controller) - I can defintely recommend...
... Wayne, That link looks to be broken right now - is the server down? I'm interested in learning more about what you've done at the protocol level. I was...
... Sorry about the typo: <http://gramlich.net/projects/rb2/controller28/rev_c/index.html> ... I'll talk about this more in a message tomorrow; I've had a long...
I'm interested in building some robobricks. So the first thing I wanted to figure out is what is the CAN Protocol. After reading the messages to the ARM guy...
Shannon: ... The primary reason for using UARTs on top of CAN bus physical layer vs. full up CAN bus is primarily to reduce cost and complexity. Full up CAN...
Yeah, I looked at your document later, then remembered from a while back that you were using the CAN transceiver over a uart bus. For what you're trying to do,...
... The module names are not very intuitive. The WireHost module provides RS-232 to RoboBricks2 bus. The connector on the WireHost module is an RJ11-4. I had...
Hi Wayne, I wanted to complement you on an excellent presentation at the HBRobotics meeting last week regarding RoboBricks2. Very inspiring... I had a...
... Thanks. I had a good time giving the presentation. (I should mention, I have been getting totally hammered with colds this cold season -- I'm currently on...
... We have one that is built out -- Rev. C. ... We have one that is 50% built out. It needs the resonator and the the LCD panel. Both are in my private...
... Terrific. I hope you are feeling better soon. I'll wait to hear from you to get the boards. Out of curiosity, what's the pricing by the way :-). Also, a...
... In general, Olimex charges $45 for a Eurocard (3.9"x6.3") sized PCB. I can get 7 1.25"x2.50" RoboBricks cards on a Eurocard. this works out to be $45/7 =...
Hi Wayne, OK - I'll put in my request for modules as well. 2 x Controller 28 - with no PIC processor populated 2 x DB9RJ11 1 x wirehost 1 x IO8 1 x splice 1 x...
If the controller28 has an ISP (in system programmer) header a bootloader for me would not be necessary as I'll just use the AVR ISP or STK500 to program the...
Hi Wayne, So if I'm reading things correctly, the current bootloader is written in uCL and the uCL compiler is written in STIPPLE. So STIPPLE generates ANSI C....
... Dave: uCL generates an assembly file (.asm), an assembly listing file (.lst) and an Intel hex file (.hex). In theory, the .asm file should be able to be...
Hi Wayne, ... I just turfed XP (not quite completely - I installed vmware) and installed OpenSUSE 10.2 on my laptop. ... I've always been interested in...
Hi Wayne, So, in reviewing the boot loader protocol, I have a couple of questions: 1 - I'm assuming that "Address Set" specifies a word address. It doesn't say...
... It sets a 16-bit address value. For PIC16's, instructions are 14-bit quantities. Address 0 refers to the first 14-bit instruction, address 1 to the second...
... One of these days I need to install vmware on my laptop. Right now I dual boot to XP or SUSE 10.0. I spend 99.9% of my time in SUSE. ... Most scripting...
Hi Wayne, ... In anticipation of getting my hands on the RoboBricks2 modules I looked over the Controller28 module with regards to using it with the ATmega88....
