The Portsdown software does not yet support the LimeNET Micro, but will in future.
 
  
−
The supported configuration will be 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.

===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.
