CARL9170 Firmware Configuration
+-------------------------------
When building the carl9170 firmware you will be prompted with
configuration questions.
+atusb: Firmware for the ATUSB IEEE 802.15.4 USB Adapter
+-------------------------------------------------------
+
+To flash the firmware you need dfu-util on the host. Issue
+
+ make dfu
+
+right after plugging the device into the USB port while the red led is
+still on.
+
+Refer to the included README file for more information.

+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.
+
+
+HULUSB notes:
+-------------
+To prepare and flash the firmware on a HULUSB device some additional steps are
+needed;
+
+avr-objcopy -O ihex -R .signature -R .fuse -R .eeprom hulusb.elf hulusb.hex
+dfu-programmer at90usb1287 flash hulusb.hex
+dfu-programmer at90usb1287 reset

+workflow:
+
+- connect zprobe (note: it currently inverts because it didn't have any
+ other chips around. this may change later.)
+
+- capture the USB signals at an interesting moment with a sample rate of
+ 50 MSa/s
+
+- zoom into the frame(s) of interest
+
+- download the data with
+ ./get.py
+
+- decode with
+ ./dec.py
+
+ For manual decoding, set the coders to D+ and D- (we need D- for SE0
+ and SE1 detection), then click on a rising clock edge left of the
+ packet and move the cursor to the right.
+
+- if there are problems with the clock, the analog signal and digital
+ signals derived from it can be examined after running dec.py with
+ ./plot
+
+ (Note that the digital zprobe hides any analog anomalies.)
