[quote author="ericwertz"] But Rubi, AVR doesn't even have an Ethernet solution... a lot of AVR people are using Microchip's...! :-) I can't fault you for your interest in ARMs though. [/quote]
Yes but Avr has Arduino, the best free microcontroller dev. platform I have ever seen (although the Editor is lousy,...) . And the Arm has power.
There are so many interesting platforms, f.e. Ti msp430 low power controllers, but time is the limiting factor so I decided to stick to two platforms and that is it.
Please no religious micro discussions, it does not make sense since they all are great.
[quote author="ian"] I've got a bunch of demos planned, and I'm happy to take requests too.
I'll port the #twatch firmware to the web platform, it has enough I/Os for a 4bit LCD interface. Then the wp can be used as a development board for the burn-limited #twatch. I developed the #twatch on a 24FJ board, so the firmware already compiles on the 16bit devices. After that, maybe custom feeds, etc. because the SD card provides a means to enter the login credentials. For the tweet_tree I made massive improvements to the JSON parser state machine, eventually I'll port these back to the #twatch. ...[/quote]
I am more than conviced, just bought one. Do you know which chip is missing @ seeds and stops the delivery ?
>I'll ask seeed to find a cheap USB->serial cable and make the header >compatible with that. If you could use the pinout of the ftdi cable, that would be great. This became a quasi standard.
I would also like to clarify my statement. Fan (Eric) does a terrific job at seeed, fast shipping, tons of new proto boards, great prices,... Recently I prefer his shop to sparkfun, the no.1 for prototyping needs. Imho he cannot be blamed for the lousy shipping times of HK post.I hope the will learn to handle the great shipping volumes better or at least dhl will get cheaper.
Do you plan any cool projects for the platform, like a twatch with posibillity to login and watch the feeds from friends ?
The web platform is really awesome, but I am not interested to learn a new platform. I am more interested in avr and arm controller a third fimily would be to much.
But with some interesting finished projects the platform would be still interesting.
My last seeed order took alone 2 weeks (!) to get from seeed to hongkong post. I could live with 2 weeks to delivery but recently it is more 4 to 6 weeks. I hope the learn to handle the big volumes at hong kong post. But since september last year it is getting worse and worse.
[quote author="ericwertz"] Interesting. The USB controller on the PC side is supposed to prevent this very thing from happening. It's also supposed to know that if it can't provide 500mA when you ask for it, then it shouldn't try to honor the request. [/quote]
You can try this very easy, just short the 5V Pin of any Usb Port against the chassy of your pc and you will notice an immeadeate reboot. I have lost quite some code this way.
My kill stats: 1 parallel port (this did really hurt) 1 usb hub 1 usb port
For about 10 years of hardware hacking not soo bad.
[quote author="ian"] That's what I thought too. Nate at SparkFun and I had a conversation about this a while ago. He said he was really impressed by the resilience of USB ports in terms of shorts. [/quote] Imho the most impressing port was the RS232 port, unbelievable how much abuse they could stand.
I like the v2a because it can use its own power supply. Sometimes I have a short circuit on a quick and dirty test board and that would lead to a pc reboot if I use usb as power supply.
Yellow led and errors like these when programming with the python shell: Verification failed at 0x00000000: 0 != 4 Verification failed at 0x00000001: 4 != 12 ...
When clicking the green button using the pic24p programmer the yellow light is off, but when i unplug it and plug it on again, the yellow ligth is back. I also updated my v2go but without any troubles.
Update: My v2a is now alive again, with the 2.8 software. It seems the newest v3.6 or 3.5 do not work with the v2a buspirate.
Had the same toubles with my self built twatch, missing characters and connection error. After uploading the code version posted in this thread my twatch is working now.
Only one thing, my twatch consumesv 160 mA and the pic gets pretty hot. Is this normal ?
