What the heck is this thing?

----------------------------

It's a bootloader for AVR and other micros that can deliver your code

to the MCU via cheap nrf24l01 wireless modules. 

Is it good?

-----------

* Clean architecture

* Very portable, since it's based off antares

* Easy to integrate external memory devices, since 

  it supports several memory partitions. 

* Easy to add your own device-specific hacks.

Can I use it with arduino?

--------------------------

Yes, you can. The bootloader doesn't care where you got your file from.

Be it arduino, avr-gcc, avr-brainfuck compiler, /dev/urandom or even astral ;) 

Does it work with intel hex? 

----------------------------

Not yet. rf24tool only accepts binary files. So either add -Obinary to your

makefiles, or use srecord/hex2bin to get a binary file. 

Does it work under windows?

---------------------------

No. Only Linux and other *nix flavors that have libusb. Patches welcome. 

Does it work under Mac OS X?

---------------------------

No. Only Linux and other *nix flavors that have libusb. Patches welcome. 

What about usb programming dongle? 

----------------------------------

See README.dongle

How to connect nrf24l01 with avr/arduino?

-----------------------------------------

See README.compiling. If the relevant section is not enough for you, I 

suggest you give official nrf24l01 datasheet a read as well as avr's 

datasheet. I can't pack a book 'avr for dummies' into a small README file. 

Sorry. 

Can I use nrf24l01 wired directly to Raspberry Pi/OpenWRT Router/Toaster?

-------------------------------------------------------------------------

Theoretically - yes. Practically - you'll need to implement spidev or 

gpio-bitbang adaptor for rf24tool. 

See rf24tool/adaptor-uisp.c as a reference. 

This is TODO, yet not a priority one.

Daunting documents worth reading

--------------------------------

README.compiling - How to compile the bootloader for your device.

README.hacking   - If you want to help out by porting to new devices.

README.dongle    - How to get your programming dongle up and running. 

README.app       - How to compile the userspace app.

Dude, this crazy stuff is too hard on my brains

-----------------------------------------------

And who said it will be easy? Go take a break, try again and send me some 

patches.
