DS1820 has me 1-wire away from giving up on my project
In previous threads, some have taken the "1-wire" a little too literally. You still need a ground connection so that you have a complete circuit.

Please Recommend some Universities && Electrical Eng
My favorite is Michigan Tech in Houghton Michigan. A highly respected engineering school, but you better like snow!

If you use the circuit you have shown for the MAX487, there is no need to forward anything, since all 50 AVRs see the same data. The addressed AVR should send back an...

Your application is exactly what RS485 was invented for. The ATtiny2313 has 1 full duplex UART. Connect a MAX485 or simular chip to this UART insted of a MAX232. Connect all of...

Microcontroller to Microcontroller UART distance
As far as your program is concerned, RS232, RS422 & RS485 all use the on chip UART with an external driver chip for the proper signal levels. For 422 or 485 you program needs...

SPI with Interrupt and 16-bits ?
As long as you are the master, you control the clock, so doing 16 bits as 8 and 8 works just fine. That is the nice thing about SPI, the clock bits doesn't need to to be uniform....

program coda and data separately
If you are using one of the later AVR, such as the mega8, which allows programming by pages, you can put the data & program in seperate pages. When you wish to change the...

RWW/NRWW again...
Having the loader rewrite itself is possible, but must be done VERY carefully :twisted: Not for the faint of heart.

[General frustration] ARGH! Those datasheets.....
Just submited my survey, including my displeasure at not longer being able to cut and paste. If we retype the information ourselves, we are bound to make errors, which is the...
