Try the new version of the in circuit programmer, the AVRISP mkII. It's about 35 bucks and uses a USB interface. If you can find an older version of the serial interface AVRISP, they work quite well with a USB/Serial adapter. Problem with the ISPs is if you have a brain fart and

One way that I do it is to have the routine set an I/O port on the way in and turn it off on the way out. Then I attach an oscilloscope to the pin I'm using and measure the amount of time the pin stays high and that's the duration of my routine. As with nearly anything else, ther

You all are going to keep it up and we're going to be accused of being inhospitable to newbies suffering from DNS syndrome again. Just copy your CodeVision manual, convert to a pdf file, and send it to the poor kid...all at your own expense...for software you've bought yourself.

These are looking very interesting. However, I'll be darned if I can find out any specifications on how much power these cards consume. Do you know where I can find real data sheets on them? On the cards that is, not the sockets. A search on "microsd data sheet" on the SanDisk we

Yes, I am using those that are used in digital cameras and such. You can get connectors for SD cards from Digikey, Mouser ec. There are 2 big advantages in going this route. One is cost. As I said earlier, a 1GB SD card is about $6. Using any other type of flash memory is going t
2007-12-21 by Steven Hodge
I'm looking for at least 1 MB, so that's 8 of those babies, so then it gets to be a pcb space issue. The reason I'm trying to avoid SPI is just the usual I/O pin scarcity and I already have three I2C devices so am committed to that bus regardless. Memory is the only reason for SP

I believe that Ramtron makes some. They are zero-wait NVRAM, not exactly flash or EEPROM, but I've had good experience with their stuff. I've only used SPI versions but I think there are I2C versions, also. Jim On Dec 20, 2007, at 10:39 AM, Steven Hodge wrote: > Does anyone know
