[quote author="afedorov"]It's showed just before initializing of the I2C bus, so the problem is probably with pullups[/quote] Yep. you are correct, it was one of the pullups(r28). thanks man
hi guys. had the unisolder abandoned for some time due to lack of time and a working pickit , but i finaly started "finishing" this awsome project. the problem i'm having right now is that i cannot program the firmware. i can program the bootloader without any problems (screen come on with the moving lines, the computer detects it perfectly) but whe i try to program the firmware the unisolder app crashes, and on the screen i get "13". if i try to program it from mplab(pic standalone) i get the same thing. does anyone have a sugestion? thanks
[quote author="valerionew"]Does sameone have a spare board (in europe)? I've not finished yet to read the entire discussion, so I'm sorry if someone already posted an easy answer to my question :)[/quote]
There is a guy from Rusia Seling on ebay.. realy good price also...Also he sells the components that go with the board (like 105€ shipping included for PCB+parts) I tried to build my own bom on farnel Spain, and with a few parts missing and came around 80€.. so I think it is worth the price he is asking
Hi. First of all thank you for an amazing project. i have an idea for an improvement. to be able to use the dual tool feature with 2 different irons, this will need some PCB modifications and a firmware upgrade. the idea is to add another iron sensor to control the sleep/wake of the iron that is picked up and in addition to lock the second iron and that it is left on the second stand. this could be done with a multiplexer to switch between the sensors when both irons are in the stands (use a ironactivated variable). same thing to do with the iron id. sense and iron voltage could be switched with relays. so when you pick up the iron 1, activate the heater/s relay/s and temp sense of iron 1 and lock the iron2 and only unlock when iron 1 is put into his stand. when i'll have more time (first to finish my unisolder hahahah) i'll try adding a tft with touch control and make an ui like jbc dde, dme, nase with all the solder irons
