This function set isn't really usable for real communication. Its main purpose is to help with testing the firmware. - tools/lib/driver.h (struct atrf_driver): added driver functions for HardMAC access - tools/include/atrf.h (atrf_rx_mode, atrf_rx, atrf_tx), tools/lib/atrf.c: functions to enable/disable HardMAC mode and to send/receive frames |

Requires a very recent toolchain, because ATmega32U2 is relatively new.
- Building:
make
- Uploading the firmware to a Ben (for flashing with the atusb-pgm cable):
make HOST=<hostname> upload
Example:
make HOST=ben upload
HOST defaults to "jlime".
- Flashing the boot loader:
Prerequisite: avrdude on the Ben.
Disconnect the atusb board from USB. Insert the atusb-pgm connector into
the Ben. Place the atusb-pgm adapter on the exposed contact pads of the
atusb board and push it down. Then run
make prog
This takes about 30 seconds. If the programming fails with an error
message like "Yikes! Invalid device signature.", verify that the
atusb-pgm board is properly connected and placed, then try again.
- Uploading the application:
Prerequisite: dfu-util installed on the PC.
Insert atusb into the PC, then run
make dfu
Note: since the boot loader resets the USB bus after timing out,
this operation can fail with a message like "No DFU capable USB device
found". Just retry, and it will eventually get through.
