Programming Box Support; Flashing The Aquastar/Dlux With Avrrootloader - HobbyKing OrangeRX RX3S Manual

FlightStab Guide
To reset the EEPROM to default values, use a jumper to short the pin pairs for the device and then power up.
Device
RX3S
NanoWii
On reboot, the device will clear the EEPROM and flash the LED rapidly in 3 sec bursts, which indicates that
you can now power off the device and remove the jumper. On the next power up, the EEPROM should start
with the default "factory reset" values.
Normally, the plane will wiggle the surfaces 3 times to indicate that calibration has completed. If the EEPROM
was reset to factory default (either on first boot or on jumper reset), the plane will wiggle the surfaces 9 times
instead. This can be used to indicate a problem with EEPROM corruption when you do not expect the
EEPROM to be reset.

Programming Box Support

FlightStab supports configuration through the Aquastar or DLUX programming boxes. Using the programming box is
more convenient and will allow more options that using the stick configuration.
The steps to enable programming box support are:
Use the USBASP ISP programmer to erase the chip, update fuse settings and flash the
AVRootloader_AQUASTAR.hex bootloader
Use the AVRootloader to update the main programming box firmware:
2013xxxx_AQUASTAR.hex for the AQUASTAR box
2013xxxx_DLUX.hex for the DLUX box
Connect the programming box to the FlightStab device through the "one-wire" servo connector and power
them up.

Flashing the Aquastar/DLUX with AVRrootloader

On the Aquastar, the CPU is exposed, so it is highly recommended to use the HK chip adapter for the ISP cable to
the USBasp. The ISP pads are also exposed on the PCB if you want to solder the signals instead.
On the DLUX, the CPU is hidden behind the LCD board, but the pads are exposed just above the 3rd and 4th
buttons. The ISP pads have the following definitions (from left to right):
GND 29
GND RESET
After connecting the USBasp programmer to the program box via the ISP connector, the next step is to erase the
chip and set the fuse for bootloader support.
Select the target chip type as ATMega8A chip (and not ATMega168pa) on the programmer (eXtremeburner,
AVRDude, etc).
