USB-RFM70 RF transceiver adapter

[visakhanc]

Hi all,

Here is my project called usbXR, an adapter for RFM70/73/75 2.4 GHz RF transceiver: https://github.com/visakhanc/usbXR.
The intention of the project is to communicate with other RFM70 based remote nodes bi-directionally from a PC, for any kind of application.

It features the original HID-Bootloader extended to add a functionality to program remote AVRs over-the-air. The original BootloadHID command line utility is also modified to do self as well as remote over-the-air programming.

Here is a small demo video: https://www.youtube.com/watch?v=0iYNhQ-_6nI

Nice.

I was just wondering: do you need an m328? Wouldn't a smaller MCU work as well?

Hi,
I needed more than 2kB of boot space, as my bootloader is >3kB (which includes HID bootloader plus a functionality to program remote AVRs through the RF module over the air). ATmega8 can be used if only HID-bootloader is enough.
Thanks
