I think what he’s asking is if you will have to switch between pin 7 being for LVP or for temperature.
Wasn’t it hardware limited that there were not enough pins to do both at the same time?
Narsil v1.3 and v1.4 switched from voltage divider to internal voltage reference to add the indicator LED
Also temperature protection was added
Hardware limitation is only to do indicator or 2S LVP in next Narsil version
To be more precise,
i was asking if i now get the 1.2 2S Narsil driver with LVP on PIN 7 and then Tom’s NarsilM comes out with LVP set on PIN7, i flash it on the driver.
Will i then have both at same time 2S LVP + Temp Protection ?
Or it still will be a choice between 2S LVP or Temp Protection?
Hope its clearer what im asking.
NarsilM has of course temp protection avaialble, no external pin needed for it
when flashing NarsilM pin7 must be set to external voltage reference then compile the hex
if done right you can simply flash NarsilM over a v1.2 and it works
parts from digikey arrived
starting to reflow
Thanks for the info , all clear now.Will shoot you a pm with my order
a lot reflow work done
cleaned and visual inspected
Been there, done that. That is a lot more work then it looks like (and it looks like a lot).
What do you guys use to inspect them, a magnifying glass?
I’ve found that my phone camera set to 5x zoom and a small flashlight makes for a very handy video microscope kind of thing.
If I had to do a lot of drivers I would get a tiny turntable so I could rotate each driver while holding the camera and light fairly steady. It’s so much easier on my eyes. :+1:
I always wear a magnifying headset when soldering these types of things, no way would I try to do that with the naked eye on a regular basis.
I have a much stronger 10X magnifier for detail inspections if I need it.
I need a magnifying headset. Do you know of a good one?
I got mine at harbor freight many years ago, they have a different one now. It should still work but only has the extra magnifier over 1 eye instead of both like mine. They are sell them on amazon as well.
Soldering smd stuff for me is like firing a sniper rifle. I set up the shot, hold my breath and gently make quick contact to the joint. Then I breath and check my work. Lol
It is much much easier when you can see what you are doing. I really want a big desktop magnifier or better yet a microscope but they are a weee bit more then the $5 I spent on the headset, so I will live.
for inspecting this tiny stuff enough light is more important than magnification
I dont need magnifier to check those boards, if there is a bridge I see it under my 1000 Lumens desktop lamp which has a narrow beam
This is why I don’t even bother trying to use an iron for smd anymore. Solder paste + hot air is much easier.
Thats how I make those hot air gun and solder paste.
I only occasionally swap resistors or add leds in the 1206, 0805 range. So not very often. Hot air station for me doesn’t make sense cost wise. I’m okay with an iron, but a good magnifying head piece with lights built in might be my next purchase.
If I built drivers, then a hot air station might be worth the expense.
I am trying to get the OTSM drivers to work,
first
does only get low mode, nothing else
the 2.
gets only low-medium-high
tapping often does not enter config mode
long clicks are not working at all
the 3. only in low mode
