I've only chosen the PIC because I've got the debug board and a few samples knocking around. > Hooking into OWFS might be a little tricky if everyone implements > their own functionality though. I may just implement a clone of the DS2423 but without the 4k memory. > If a standard set of functionalities can be agreed on, (counter, pwm, > tri state pio, temp sensor, ADC, memory access), then almost anything > could be done If it can be done cheaply, then yes. Otherwise (personally) I'd happier with the functionality split between cheaper modules. Though, incredibly pleased that I just managed to take advantage of the very generous BAE0910 board offer! :) > I have also considered making a complete clone of the DS2490 (usb to 1 > wire master) on an AVR chip. $30 is too much for a USB -> 1wire adapter! Looks like the DS2490 is also being phased out, with only RS232 and I2C bridges remaining in production, so definitely a worthwhile project. > Would this be interesting?
