README.dongle

For programming there are 2 dongles now available. 
* A hacky dongle connected ontop of uISP (http://github.com/uISP)
* A more clean dongle based off atmega8 and a regular 8pin nrf24l01 module. 

The latter one is recommended, you can grab the schematics and PCB designs here: 
https://github.com/nekromant/nrf24l01-dongle



Bootloader for programming adaptor that interacts with a bootloader
-------------------------------------------------------------------
The dongle is based off vusb, and reuses uISP's bootloader, so once you get your 
hardware ready you need to burn the bootloader (yep, yet another one!). 

You can either get the prebuilt hex files from dongle-bootloader/
Or compile yourself. You'll have to do this if you come up with a your own
hardware design. 

 git clone https://github.com/uISP/uisp-bootloader.git
 cd uisp-bootloader
 cp config_nrfdongle .config

At this point you may want to run 'menuconfig' and check that you have the correct crystal 
frequency, proper deployment method and etc. set up.

Then run 

 make 
 make deploy #(Or manually burn the hex file from images/ directory)



Installing userspace
--------------------

Again, uISP's userspace app is reused to upload code to your device, so we'll need 
to compile and install it. 

Follow the instructions here: 
 https://github.com/uISP/uisp-userspace 

Compiling dongle sourcecode
---------------------------

Either grab a hex from dongle-app/ and upload it to your dongle by running

 uisptool -f ./dongle-app/rf24-16M.hex

Or compile by hand: 
   -----------------


 cp config_nrfdongle .config
 make menuconfig (adjust whatever you want)
 make
 make deploy
 
Known Issues
-------------
I know at least one USB 3.0 host that screws up somewhere along the way and 
data corruption happens. This is likely vusb-specific.
