I should go read the release notes carefully, I haven't upgraded yet, so I haven't looked at them. Some comments below. I hope my comments clarify, but, fair...
... yet, so ... [much snippage] ... Dave: Thanks. That is exactly the kind of information I was looking for. Could you (or anybody else) enlighten me about...
As some of you know, I've been working on a system similar to RoboBrick2 that uses the same connector but a different mechanical form factor and and talks CAN...
All: For the holiday season I managed to get myself an AVR-Dragon programmer/ICE system. Using the Dragon, I was able to write a program in C (including fuse...
... http://www.hbrobotics.org/wiki/index.php5/WRTSL54GS#Using_on_board_serial_port ... Brandon: I have not posted a circuit the WireHost conversion. The longer...
... On the subject of hosts -- one thing I am excited to play with but haven't had a chance, is the Atmel AT90USBKEY development board. This board is $36 at...
Dave (Curtis): The AT90USBKEY is a neat and inexpensive board. ... I just checked, it seems to be $31.92 at Digi-Key. ... My further comments are: 1) The...
... Bonus! Its gone down. ... That's worth checking. I've heard that the Dragon can debug up to the first 32K on the larger processors, so you just have to...
... Hi Wayne, Thanks for the additional information. I still have not got this working yet. One thing that is a little confusing to me is that above you say ...
... You are correct, that is a typo on my part. ... For revision C of WireHost, pin 11 and pin 15 are connected to ground. Other things to check are whether...
... [snip price] [snip AVR-Dragon issue] ... I do not have one yet. [snip .050" x .100" connectors issue] ... Actually, it can be touch and go. It depends...
... That is interesting. I have rev C but no connectivity between pin 11 and pin 15. I've jumped the two together now. ... Changing the baud rate in microcom...
... Perhaps a manufacturing defect? It is not something that I would easily detect, since that buffer of the Max232 is not used (i.e. pin 14 is NC.) ... ...
... <much snippage> ... Yes, I wasn't thinking about these being through-hole pads. So maybe a smallish pad, and don't try to route between them. ... Well, at...
So some good news. I can now talk to WireHost from the router using both on board serial ports! To get /dev/tts/0 to work I have to boot the router first then...
... Argh! I knew that and I did not write it down! We have to plug and unplug it as well. I have no idea why. ... I did not know to set the IRQ. That works...
Wayne, The ATJTAGICE2 at $300 is a bit pricey. But I just ordered 3 of the AT90USBKEY boards. I can help out with the software and if I really need to...
... The guy at <http://www.fourwalledcubicle.com/MyUSB.php> claims that his library is in stable condition. If it really is stable, all that should be...
... Yes, I do. So if you get stuck, let me know. As you say, once the CDC driver is up you can define an endpoint for stderr and get a lot of debug done that...
Dave and Wayne, So far, so good as the tools installed seamlessly and MyUSB downloaded and extracted without a problem. The "make all" build after a "make...
... It sounds reasonably robust, but does USB need that level of complexity? I honestly do not know. All I need from the AVRUSB is a USB stack that can talk...
Wayne, ... Your question about USB's complexity is a common question. Most people think of it as a gloified serial port. Which it is but it does have a lot...
... Having a scheduler still seems a little complex to me, but it is probably a simple scheduler. ... And presumably it worked. ... Configuring up the AVR UART...
Hi, Last night I started sketching up ideas for a carrier board for an AT90USBKEY. My thoughts are to do something minimal that simply forms a back-to-back...
... I would lean towards option 1. Maybe take a few of the more interesting I/O pins and bring them out (say the SPI pins, and the 2-wire (I2C) pins.) The...
... I've been thinking about this some more and had two more observations: 1) I have typically put some sort of power supply with a switch on boards that that...
... The processor certainly has the bandwidth to handle it all. So far I've made the assumption that Dean's firmware is structured such that it wouldn't be...
