hi all, i simulated a bootloader test software (as attached) on the avr studio simulator. what i did was i created a very simple application program. i then hardcoded the hex file via the bootloader program. (i'd do anything to get the bootloader running!) this is the result fro

You are absolutely right David, good point! Now that I think about it... I should have said something like that as I work very closely with the local distributor and with the regional Atmel engineer. I have on rare occasion ordered from Digikey but mostly use the local distributo

It might be appropriate to define your requirements as to what you need. Then head over to www.atmel.com to find an AVR that meets your requirements, there are many with 8 I/O and up. Or if you would rather ... you put up your needs here as to what your are going to do with it an

Hi all, My wifes reader accepts almost all the current memory cards/sticks. I noticed that the SD and Sony MemStick fit the same slot. In my searches for any technical data on the Sony, I drew a blank. Does anyone know if these devices are even romotly interchangeable ? Dave

There is no jitter between pulses as the timer match condition finishes one pulse and starts the next. The processor has up to the minimum pulse width to service the interrupt and set up the next match. The only jitter would be the start of the pulse train and that would be whate
2005-11-12 by Kevin
While the time between the pulses may move around a bit, this causes no problems to a servo. It is the pulse width of the pulse that matters, not the period. That said, with analog servos a faster update rate (period) makes them stronger, a slower one makes them weaker. I've expe

Another approach you might consider is to use a timer as a one shot pulse generator and reset it periodically based upon some other timer (i.e. the system timer) the OCx register is set to “clear on match”, so you r register, then set “Set on match” and then “force match”, read t

Yes, the I/O direction pins are set. Actually since this is part of a large project I’m going to press ahead with something else and assume that I get it right sooner or later. Perhaps when I come back to it I’ll have better luck. Martin Jay McKee

What timer were you using in the simulator? I'm using T0 in the 168 and I can load it & introduce an interrupt. The interrupt is cleared but there is no vector to the ISR. Dennis ----- Original Message ----- From: Loren Boyle To: AVR-Chat@yahoogroups.com Sent: Wednesday, November
