Re: [AVR-Chat] multi-drop slaves

2006-05-18 by David Collier

Thanks Jim, I'm looking at 10 feet or so, so I want I2C or similar. I'm trying to do a "conceptual replacement" for something resembling a 1-wire architecture. I've just looked at the various ATtinies, and I hadn't realised what a variety of serial interfaces ( or lack of them )

Ok, what you want is replacement constants to use in the expressions you presented for code space. .db actually assignes it to code or eeprom. For numeric constants, it is .EQU name = value String type is not given as a valid expression for AVRASM2! A single character probably wo

Both SPI and TWI (I2C) are multi-drop. SPI requires a separate enable (chip select) for each device so that could mean a lot of "wires". Neither is designed for more than a few meters. For regular serial, RS422 is the one-talker, many listener protocol and RS485 is the many-talk,

Actually, you can already do SNOBOL4 on an AVR, there is a snobol to C "compiler" which you could then use gcc to generate code for the AVR, a little rube goldberg-ish, but I think it would work. On 5/16/06, Zack Widup wrote: > > > What's next? SNOBOL and SPITBOL? Maybe throw in
