About

The Eurgle/FlySky/Imax/Turnigy 9x r/c Transmitter is a nicely built unit basically copied from a more recognized manufacturer.

The unit itself hosts an Atmel AtMega64 8-bit MCU. The hardware includes 2 sticks, 3 potentiometers and 7 switches. It also supports a 128x64px screen without a back light.

This project aims to replace the software that comes with the standard transmitter with a more powerful and flexible version.

This project is based on he th9x project. http://code.google.com/p/th9x/

WARNING! Deleting a model causes the memory to jump to the previous model memory in the list. Do not delete a model memory while you have a model "listening". Always shut down your receiver before deleting a model.

Build and Program Instructions

Full programing instructions

Flashing the 9x by Jon Lowe.

Required libraries
avr-gcc, avr-libc, gcc, avrdude, libusb, bulid-essentials
Ubuntu/Debian commandline: sudo apt-get install avr-gcc avr-libc gcc avrdude libusb bulid-essential ruby

Building from Source
First checkout using svn: svn checkout http://er9x.googlecode.com/svn/trunk/ er9x
Enter the src/ directory.
To make the standard version type: make
To make the JETI DUPLEX enabled version type: make EXT=JETI
Windows Compile Tutorial by Telemachus.

Flashing (you may have to run as admin to access the USB port in Linux)
To write the FW: make wflash AVRDUDE_PROGRAMMER=usbasp
To write the EEPROM: make weeprom AVRDUDE_PROGRAMMER=usbasp
To read FW: make rflash AVRDUDE_PROGRAMMER=usbasp TARGET=backupflash
To read the EEPROM: make reeprom AVRDUDE_PROGRAMMER=usbasp TARGET=backupeeprom

Make sure you replace "usbasp" with the name of your programmer.
To list available programmers type: avrdude -c ?

make targets

make all (default): build the source
make clean: Remove compiled files and directories.
make wflash: Write flash (program) memory.
make rflash: Read flash memory.
make weeprom: Write eeprom.
make reeprom: Read eeprom.
make coff: Convert ELF to AVR COFF.
make extcoff: Convert ELF to AVR Extended COFF.
make debug: Start either simulavr or avarice as specified for debugging, with avr-gdb or avr-insight as the front end for debugging. (for debug info look into the makefile)
make filename.s: Just compile filename.c into the assembler code only.

make options

EXT=JETI: make jeti vesion.
AVRDUDE_PROGRAMMER: Set avr programmer name (to list all available: avrdude -c ?) - default: usbasp
TARGET: Set target name - default: er9x
OPT: Set optimization level - default: s
FORMAT: Set format (can be srec, ihex, binary) - default: ihex
MCU: Set MCU - default: atmega64

Making your own splash screen

Create a XBM bitmap file that is monochrome and 128x64 in size. (GIMP is a good program for handling XBM files).
Save your file as "s9xsplash.xbm" in the src folder.
Run "make s9xsplash.lbm" (this will convert the XBM file to the lbm format)
Run "make" with whatever options you need.
Once "make" finishes - the FW will be in the er9x.hex file in the src directory.

Please note that in order to compile this under windows you need ruby
