Hey! I am working on custom FW for joyetech devices with large screen (64x128). It called like my nick.
Now it looks like this (some screens)
I think to do something like this
It's feature that I want to make
-Regulated source of energy mode - it's not just powerbank, it can use any voltage/wattage/TC in the end or connect some devices
-Puff detection - in this mode you do not need press fire button, all you need is start to puff
-Flashlight mode
-Remember last time when battery changes (keep system time)
-Swap Fire to +- button - for stealth vaping (Fire could be quite loud) or if you Fire button is halfbroken
It' realized features
-Battery protection (charging will be stoped at maxtemperature-21C)
-A LOT of interface changing, some of them still not stable, but we work on it
-Better TC screen (screen refreshes 10 times per second, not 2)
-Less time for some reaction. You know Drag with 0.025s fire delay? We set 0.010 and it works ^_^
-4 level for brightness - 0-33-66-100-0...
-Optimized control
-Fire screen counter changings (it keeps screen alive)
PS: also, UR free to write some code. if you want. You could fork my custom from GitHub
