12:22 AM nohit: --
01:29 AM rue_mohr: I made a 6 phase charge pump
01:29 AM rue_mohr: now I can rest knowing its not amazing
06:33 AM _abc_: Hello. I am trying to use I2C/TWI on 328 in slave mode, promiscuous. Think bus pirate replacement, to log I2C traffic without participating. This turns out not to be possible, since the ACK bit is not controllable by the programmer in the TWI hw peripheral. Correct?

12:59 PM rue_bed: k
01:00 PM rue_bed: you can, you might have to make a modified slave tho
01:00 PM rue_bed: the hardware does not do everything
01:01 PM rue_bed: it just shifts in the bits and tells you when x many bits were shifted in
01:01 PM rue_bed: its ALMOST software i2c
01:01 PM rue_bed: which is why I keep promoting software master, its actually less code
01:02 PM rue_bed: and easier to do...
04:22 PM _abc_: rue_bed: sorry read your reply late. I read the ds and it's not possible to make a non responding passive listener with avr328 TWI hw peripheral, the ACK bit cannot be disabled.
04:22 PM _abc_: Software is the way to go, yes.
04:24 PM nuxil: i find Peter Fleury's i2c implementation to be one of the best.
04:24 PM nuxil: for ,aster
04:24 PM nuxil: *master
04:26 PM _abc_: I need slave, and interrupt driven on pin change.
04:26 PM _abc_: No problem, I can do it.
11:02 PM rue_shop1: cool, I ported flurrys to C if you need to run it on something else
11:02 PM rue_shop1: its not quite as good, cause thats DAMN good assembler
11:05 PM rue_shop1: ok, core is in....
