V1.11 - Adding a Boost mode

Allows users to enable a boost mode.
This allows you to hold down the button near the tip while soldering to
temporarily boost the soldering temperature.

 # 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. Downloads for the hex files to flash are available on the [releases page.](https://github.com/Ralim/ts100/releases)
-**You will need a windows computer (7,8,10 tested), using the normal windows explorer to load the firmware.
-The bootloader does not appear to work under mac or linux at the moment.**
+Officially the bootloader on the iron only works under windows. However, users have reported that it does work under Mac, and can be made to work under Linux. Details over on the [wiki page](https://github.com/Ralim/ts100/wiki/Upgrading-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. Disconnect the USB and power up the iron. You're good to go.
 
 For the more adventurerous out there, you can also load this firmware onto the device using a SWD programmer.

 This menu allows you to cycle through all the options and set their values.
 The button near the tip cycles through the options, and the one near the usb changes the selected option.
 Note that settings are not saved until you exit the menu, and some settings such as screen flip do not apply until a power cycle is applied.
+If you leave the unit alone (ie don't press any buttons) on a setting, after 3 seconds the screen will scroll a longer version of the name
 
 * UVCO -> Undervoltage cut out level, settable in 1V increments from 10-24V
-* SLTME -> Sleep time, how long it takes before the unit goes to sleep
 * STMP -> The temperature the unit drops to in sleep mode
+* SLTME -> Sleep time, how long it takes before the unit goes to sleep
 * SHTME -> Shutdown Time, how long the unit will wait after movement before shutting down completely
 * MOTION -> Wether motion detection is enabled or not
-* TMPUNIT -> Temperature unit, C or F
-* FLPDSP -> Flip display for left handed users
 * SENSE -> Motion Sensitivity, H is more sensitive. L is lowest sensitivity (ie takes more movement to trigger)
+* TMPUNIT -> Temperature unit, C or F
+* TMPRND -> Temperature Rounding, {1,5,10}
+* TMPSPD -> How fast the temperature should update in the soldering status screen.
+* FLPDSP -> Flip display for left handed users
 
+Temperature rounding means that the unit will round off the temperature before displaying. This can helpt to reduce the flickering of the temperature when the unit oscillates between two temperatures.
 ## Extras Menu
 This menu defaults to showing the current temperature on the tip. 
 Pressing the button near the iron tip will show the current input voltage. Pressing the other button while this is show will allow you to calibrate the reading if your iron is like mine and is not overly accurate out of the factory. (Press buttons to change measurement up and down, press both to exit and save).

 Pressing the button near the usb enters the temperature offset setting menu, when the iron is cold, pressing the other button will start the unit calibrating for any offset in the tip temperature.
 
 # Version Changes:
+V1.10
+-Adds help text to settings
+- Improves settings for the display update rate
+
+V1.09
+- Adds display modes, for slowing down or simplifying the display
+
+V1.08
+- Fix settings menu not showing flip display
+
+V1.07
+- Adds shutdown time to automatically shutdown the iron after inactivity
+
 V1.06
 - Changes H and C when the iron is heating to the minidso chevron like images
