21:33 rue_house there it is
21:33 rue_house you wouldn't beleive how many tabs I have open...
21:34 rue_house you have two triac driver channels, so, do you ever operate them independantly?
21:34 rue_house your source is on a webpage somewhere, right?
21:35 rue_house aRef is internal, hence the cap?
21:39 rue_shop2 wow, I'm not being at all productive
22:08 Tom_itx rue_shop2, are you setting up a toaster oven?
22:32 rue_house well I was and then I got useless
22:32 rue_house I'll try again tommorow
22:32 rue_house with the triac moudules I got, there is almost nothing to it
22:32 rue_house is the code posted? is it up to date?
22:32 Tom_itx so it should have been an easy project
22:32 rue_house hahahahah
22:33 Tom_itx it's code using a pt100
22:33 rue_house I'm NOT a good person to give an easy project to
22:33 rue_house I have a pt100
22:33 Tom_itx i'm sure you can change it
22:33 Tom_itx oh
22:33 Tom_itx nice
22:33 rue_house yea
22:33 Tom_itx where did you get that?
22:33 rue_house I got it with a 20ma module, ebay
22:33 Tom_itx you'll need a serial lcd
22:33 rue_house hmm
22:33 Tom_itx there's code for that too but it may not be on the site

22:34 Tom_itx i used a 4 line
22:34 rue_house clock/data serial or like xxxx baud serial?
22:34 Tom_itx that uses a 2313 for the interface
22:34 Tom_itx the board for that may also be up there
22:34 Tom_itx i don't remember
22:35 Tom_L http://tom-itx.ddns01.com:81/~webpage/toaster_oven/serial_lcd_sch.png
22:36 Tom_L or i have a board file for it
22:36 Tom_L for either format
22:36 Tom_L 2x7 or 1 x 14
22:36 Tom_L 16 whatever
22:37 Tom_L http://tom-itx.ddns01.com:81/~webpage/toaster_oven/serial_lcd_brd.png
22:37 Tom_L sorta like that
22:37 Tom_L http://tom-itx.ddns01.com:81/~webpage/toaster_oven/ser_lcd_board2.jpg
22:37 Tom_L or that
22:38 Tom_L that's a little different than the finished board
22:38 Tom_L i added the standard plugs to the 'finished' board
22:39 Tom_L and
22:39 Tom_L i'm using PB0 & PB1 but you don't need both
22:39 Tom_L that was a boo boo
22:39 Tom_L i found out my triacs were too small so i mapped another pin and used 2 instead of 1
22:40 rue_house heh
22:40 rue_house hate it when that happens
22:40 Tom_L inflex and i were doing it together and we forgot about the 220v thing over there vs the 110v here
22:40 rue_house tho, I'v not had to make aboard level correction in a long time
22:40 Tom_L so the current was off a bit
22:40 rue_house hehehe
22:40 Tom_L easy fix really
22:40 rue_house well I have modules
22:41 rue_house you just push in 5V
22:41 rue_house dont have to make the triac board
22:41 Tom_L i could have swapped out the triac but i just used 2 boards since i had em already
22:41 Tom_L i know
22:41 rue_house do you talk to it with a computer?
22:41 Tom_L no
22:41 rue_house hmm
22:41 Tom_L it's on it's own
22:41 rue_house you program in the profile then?
22:41 Tom_L yup
22:41 rue_house hmm
22:42 rue_house you using the default profile in there?
22:42 Tom_L you could enhance it and make more profiles
22:42 Tom_L for lead solder yes
22:42 Tom_L not RoHS
22:42 Hyratel1 you can use a Triac like a slow-firing relay if your duty cycle is in multiples increments of 1/60th sec
22:42 Tom_L it's not perfect but it works well
22:42 Tom_L i've never had problems with it
22:42 Hyratel1 I hate LF solder
22:43 Tom_L Hyratel1 i use a triac opto
22:43 Tom_L zero crossing
22:43 Hyratel1 optotriac
22:43 Hyratel1 oh, you have a ZC sense?
22:43 Tom_L yes
