Does anyone have tips/pointers on using the TWI/I2C that they could share? I'm about done weeding through all the alligators, and I'm about ready to actually drain the swamp I came here for. Asm code would be ideal, I'm looking to implement this as interrupt driven. I'm talking t

For output lines from the 5V to 3.3V system, a simple resistive divider will do. For inputs, check the data sheets, but in almost all cases you'll find that the guaranteed levels on the 3.3V system are high enough and low enough to be valid 1's and 0's to the 5V system without mo

You all have given me a bunch of valid options - thank you. I think the best fit for my application will be the 8-to-3 priority encoder. It's not too expensive and it works down to 2 volts. Richard Cooke --- In AVR-Chat@yahoogroups.com, Samir Lohani wrote: > > > I need to read an

I've never had that problem John, but I use Netscape. The only problem I've had was anal retinitis...like the day I tried to do an update on an ISP while it was plugged into the target system rather than just power and return, at 0200 or so...on the day I was supposed to do a dog

Unfortunately I can't. I don't have the space in this design and I need to make it as easy as possible for the end user to make their selection. This limits me to a dip switch that can be switched with a pencil or finger nail. I can't expect them to have a screwdriver handy. I al

I'd agree, also 5V isn't enough to run the STK-500, and 12V is a bit too much. The regulator on the kit is a bit underdesigned, 9V is better. Get something from Goodwill, 9V at around 1A is good. And what they said on the clock speed, assuming your chips are new, they are set for

Hrm. I can set the STK-500 oscillator frequency and the ISP frequency, and I can set and read the Vtarget and Aref voltages. But any attempt to access fuse bits or lock bits results in an error box with the following text at the top: "A problem occurred while executing the comman
