Retune acceleromter to be more sensive

Has some functionality issues
Still need settings saving & movement detection

 # TS100
-This is a complete open source re-write of the software for the ts100 soldering iron.
+This is a complete open source re-write of the software for the ts100 soldering iron sold by minidso
 
-This was started to remove the need for USB for changing system settings.
+This was started to remove the need for usb for changing system settings.
 
 The software has similar functionality to the original firmware.
 
-## Features Working
+# Features Working
 * Soldering / Temperature control
 * Full PID Iron Temp
 * Adjusting temperature
 * Automatic sleep
 * Motion wake support
 * Basic settings menu
+
+# Features still to be implimented
 * Input voltage UVLO measurement
-* Saving settings to flash for persistence
+* Saving settings to flash for persistance
 * Improved GUI
-* Use hardware I2C for communications
-* Can disable movement detection if desired
-## Features still to be implemented
 * Manual Temp Calibration
-
-# Upgrading your ts100 iron
-This is completely safe, if it goes wrong just put the .hex file from the official website onto the unit and your back to the old firmware :)
-
-1. Hold the button closest to the tip, and plug in the USB to the computer.
-2. The unit will appear as a USB drive.
-3. Drag the .hex file onto the USB drive.
-4. The unit will disconnect and reconnect.
-5. The filename will have changed to end in .RDY or .ERR .
-6. If it ends with .RDY your done! Otherwise something went wrong.
-7. If it went wrong try on a windows computer, some Mac / Linux machines do not play well with their boot loader.
+* Use hardware I2C
