Hello everyone... I am curious about such a thing. Because I have two used XLIM Pro electronic cigarettes and there is a small lcd display and when taken apart you can see something like the pictures. And it makes me wonder if such a display can be used for arduino projects. I also noticed that on the board you can see two solders RX and TX . maybe it is possible to use this LCD or the whole module to program it to display something else on the screen...?
someone tried something like that ?
and this is a video of how it generally works. https://www.youtube.com/watch?v=cuZMA8QswxY
rx and tx are likely to send charge data over, the comment about firmware updates is definitely not true since these are throwaways and there's no point in updating something like that especially when it's as simple as "heat the coil, subtract one from a counter, check battery". the processing is all in the top chip and the bottom one is power management (useless for this, useful for the battery). you could most likely control the screen right from the pins, no reason you can't, but you'll have to find what the pins do. and trust me, that takes time, I have what I thought was a "simple" segmented led display off a geekbar pulse and I have yet to actually map the pins and can't find any documentation on it either because no one documents throwaway vape parts like that. so good luck with finding what everything does, once you do it's controllable. I recommend soldering in pin terminal wires for this first.
