[02:42:48] <Knaldgas> Does I need to re-enable the Watchdog after a WatchDog-reset? ATtiny15L
[05:40:46] <LeoNerd> First impressions of KiCad: I like it. I like the UI interactions - "Clarify Selection" - pure genius. Currently running into what is either a missing or a "I can't find" feature though.. but asides that all is looking nice
[06:45:42] <Lambda_Aurigae> Knaldgas, the watchdog reset just resets the timer...you have to keep doing the reset so the timer doesn't run down and cause the watchdog to reboot the chip. You do not have to reenable the wdt every time.
[06:51:18] <Knaldgas> Lambda_Aurigae: I'm using the WDT a bit unorthodox
[06:51:56] <Knaldgas> I'm using it to wake an ATtiny15L up from PowerDown periodically, and it does seem that it needs to be re-enabled at every reset
[06:54:01] <Knaldgas> Lambda_Aurigae: Ahh, I see my question was ambiguous... The WDT-reset I meant was the reset of the controller, not the counter
[06:54:43] <Lambda_Aurigae> oh.
[06:54:57] <Lambda_Aurigae> yeah, when it resets the chip the wdt needs to be reconfigured.
[06:55:06] <Lambda_Aurigae> just like when the thing is turned on.
[06:55:26] <Knaldgas> Thanks Lambda_Aurigae
[06:55:33] <Lambda_Aurigae> welcome.
[06:57:02] <Lambda_Aurigae> nice thing is, everything you have asked about so far is in the datasheet.
[06:58:38] <Knaldgas> Yes, I found it "During Reset, all I/O Registers are then set to their initial values, ..."
[06:59:51] <Knaldgas> Well,except from MCUSR obviously ;-)
[07:38:22] <nickjohnson> Can anyone tell me what size the adjustment steps are for the calibration register for the 32khz oscillator on the ATXmegas?
[07:38:42] <nickjohnson> I'd like to use the high speed crystal oscillator to calibrate it at runtime, and I'm trying to figure out what accuracy I could reasonably achieve.
[10:32:50] <Shavik|Work> I had someone tell me yesterday that they use half duplex 422. Isn't that just 485? Or does half duplex 422 exist? If so, how does it differ from 485?
[12:54:39] <Elec_A> Hello , I have defined an register with ".DEF ALBL = R2" , now i want to point to R3, how i can i do that ? i have tried "ADD R1, ALBL + 1" but it does not work .
[12:54:49] <Elec_A> *a Register
[14:53:50] <hypermagic> hello my friends
[15:15:30] <apo_> hi permagic
[15:15:41] <apo_> Think I got I2C mostly working now
[15:15:52] <apo_> ... of course, I still need to actually test it with another device ;3
[15:17:08] <apo_> http://p.0au.de/558c76bd/i2c.png it's looking pretty good, though
[15:17:34] <apo_> (Read from 0x01, then write the same byte back. There's no 0x01, so no ACK yet...)
[15:27:31] <tunixbsd> Hi,someone knows how a changel the logical lever of a pin in simulavr or in the avr-gdb ?
[18:01:36] * apo_ frowns
[18:02:00] <apo_> logic analyzer says that it's valid, but the atmega I put into slave mode won't respond to it
[19:45:21] <apo_> it handles writes!
[19:45:23] <apo_> Now to fix reads :o
[20:13:52] <apo_> Yesssssss
[20:14:00] <apo_> hail to the king~
[20:33:08] <apo_> http://p.0au.de/2c780cb6/i2c.png look at all the pretty ACKs :D
