iButton with temperature sensor

I have a bunch of iButtons that have temperature sensors in them. I would really like to be able to read the data from it but I can’t find anything on how to write a plugin that can read data from the iButton and display it on the screen. There is little to nothing on how to write your own code that can talk to the different sensors on the FLIPPER it self.
Thanks in advance.


As of writing this update Flipper only supports DS1990 iButtons. And mine are 1996 and 1904 so shit out of luck here until that changes.
