Hi Josh, I've given up with the stupid USI on the Tiny45 i think its shit and can't see it ever working. I also wrote a Manchester coding between the two...
Hi All, It's good to see you guys are into solving all the tricky problems. I'm still in the 101 class and am thankful that your guys are making things...
I've been sick lately but had a crack at the UART this weekend.. After countless debugging sessions I think I have asm code to receive a byte whenever one is...
I noticed a problem with voltages dropping (outside range of 0 - 5v) / halving (0 - 2.5v) / floating (2.5 - 5v). This happend when i forgot to make my input...
Hi all, The ATtiny45 C code below might appear buggy because it's not in its entirety but should help people to get a head start. I'm still planning on...
Nick, glad you figured it out. AndrewM, how did you want to run the "coding" side of the tutorial? If someone has a solution for the ATtiny45 UART control and...
sample for the comms of my ATmega16, as i said in my last email this code might not work as an extract but should get you underway. I plan to have a working...
Andrew and all, I'm keen for the 10th also. My robotic BMW is still at phase one with only the ATMega16 board attached. Is there any bridge boards avail that I...
Yes- there a H-Bridge boards avail. Send me an email to arrange a time to catch up. ... attached. ... this forum ... "Andrew" ... before we ... you can ... ...
Hi Andrew and all, I'll aim at getting there about 10am. I have much to learn. I never did finish the H-Bridge cables and would like to check the pinouts etc....
Hi again Andrew and all, Well it appears to me AVR Studio 4 is the tool to use. I've been playing around with it and it says: "an AVRISP with firmware version...
Hi again, I think I'll have to leave this until the weekend. It looks like AVR Studio is not picking up the programmer correctly or something is fried. See you...
Yes AvrStudio is the way to go. Did you try an upgrade and it failed or did you not upgrade and now AvrStudio won't talk to the programmer? Don't forget to...
... I will be run off my feet all today and tomorow so I wont be able to organise any food. So it might be best if we all just go get some take out or...
ok see yas at 10am at andrews! Nick ... From: Andrew <andrewm1973@...> To: robot_sig@yahoogroups.com Sent: Saturday, 9 June, 2007 1:35:39 PM Subject:...
Hi Paul, I get the same problem. Just hit "Cancel" (cancels the upgrade only) and all should work fine. Cheers and see you all tomorrow. Josh ... failed or ...
Thanks again to you Andrew for hosting an informative session. To those that weren't able to attend, we spent a good 6 hours going over code and soldering up...
Further to the previous email. Paul - the site that Josh mentioned which was good for learning AVR asm is http://www.avrbeginners.net/ ....here is a post about...
Hi, Sunday July 29th is when we plan to have the buggies ready to do a lap of the track. I'm not sure who has the track and what condition it's in this will...
Does anyone have the pin-out for the IR sensor board? I can work out how to connect it but still would like to know exactly that my guesses about the power...
Apparently from the last meeting i wrote on my board: InfraRed-on (Pulse this to turn on and off the LEDs) Analogue VCC (Appears to power the Receivers) GND ...
The rules (where ever they are) state that the track MUST be black with white markings. The pins on the IR Sensor board align with the pins on the "Brain"...
Thanks. Yep, hooked them up and sampling the Photodetectors in 8bit mode. I'm only showing about a 5%-10% swing of the values when exposed to black / white. ...
