-The Portsdown software 201907070 instroduces basic support for the LimeNET Micro.

-The supported configuration is a LimeNET-Micro V2.1 with a 7 inch touchscreen.  Use without the touchscreen might work, but is not supported.  Optionally an RPi Camera (V2 model only) can also be connected the the LimeNET-Micro (NOT a V1 Camera - it does not work).  Other supported video sources will include the EasyCap dongle and the C920 WebCam.
-===SD Card Configuration===
-A standard SD Card can be used in the LimeNET Micro.  On first-ever start-up it will reboot automatically twice before becoming operational.  On the first start-up, it detects that it is connected to a LimeNET Micro and substitutes the correct Device Tree file for using the 7 inch screen.  It then reboots to load this file, which enables it to detect the 7 inch screen.  Having detected the screen, it changes the config file to use the 7 inch screen and then reboots to load this new configuration.
-If the same SD Card is then taken back to a standard RPi 3 based Portsdown, it will detect that it is not in a LimeNET Micro, substitute the original device tree file and then reboot to load it.  It then detects that there is no 7 inch screen, changes the config file for the the Waveshare screen and reboots to load it.
-During the software update process, the device tree file is normally over-written.  If the updatedetects that it is being perfornmed on a LimeNET Micro it then reloads the file required for the LimeNET Micro.
-I have not tested it, but you should be able to build the Portsdown software within the on-board MMC module in LimeNET Micros without an SD Card slot.
-===Limitations===
-The Lime Report and Firmware Update do not yet work.  These need the latest version of LimeSuite, which I have not yet integrated because it needs testing with the LimeSDR Mini first and I have run out of time.
-===Operation===
-Select Lime Mini as the Output Mode.
-Note that UGLY mode does not (and will not ever) work on the LimeNet Micro.  However, there is no need for it as the LimeNET Micro is a far better modulator.
-The fan (if fitted) is set to start whenever the device is transmitting (after the calibration delay).  Outside transmit periods it is set to auto.
