Revision as of 09:03, 4 May 2017
This page explains how to build a GIMX DIY USB adapter.
Buy a ready to use GIMX adapter from the official GIMX shop.
A much easier but less complete tutorial is also available: DIY USB Adapter for dummies.
A German translation of a previous version is also available on the forum: old German translation.
Warning: you are responsible for the hardware you buy, and anything right or wrong you do with this.
Contents
Required hardware parts
USB to UART adapter
Make sure it works at 500kbps and that it is 5V tolerant.
chip | CP2102 | FT232R | PL2303HX | CH340 | FT230X |
5V tolerant | yes | (1) | (1) | (1) | yes |
500 kbps | yes | yes | (2) | no | yes |
compatible | yes | (1) | (1)(2) | no | yes |
(1) depends on the board
(2) only on Linux
Examples:
- MicroFTX (10$ excl. shipping costs)
- CP2102 converters on ebay (as low as 3$)
- FT232R converters on ebay (as low as 4$)
- CP2102 converter at sparkfun (22$ excl. shipping costs)
- FT232R converter at sparkfun (15$ excl. shipping costs)
- Some devices like the arduino have an on-board usb to serial chip (remove the AVR chip to use it)
- A second usb development board can also be programmed as a usb to serial converter.
AVR USB development board
Make sure it is working at 5V and that is has a chip among the following: at90usb82, at90usb162, at90usb646, at90usb647, at90usb1286, at90usb1287, atmega16u2, atmega32u2, atmega16u4, atmega32u4
There is a known issue with at90usb162, at90usb1286 and at90usb1287 boards. Other chips may be impacted. The best choice is an atmega32u4 board.
Examples:
- Teensy 2.0 board (atmega32u4, 16$ excl. shipping costs) (to build a solderless adapter, take a board with header pins) (newer Teensy 3.x and LC boards are NOT compatible as they do not have the same chip)
- Boards used for the psgroove hack (check the on-board chip).
- Arduino-compatible boards based on the atmega32u4 chip
- Arduino Leonardo - distributors - (cheap Chinese clones can be found on ebay for 11$ incl. shipping costs)
- Cheap atmega32u4 boards on ebay (about 4$). Soldering required.
Wiring
Connection table
The only thing you have to do is to connect the following pins:
USB dev board | USB to UART board |
GND | GND |
RX | TX / TXO / TXD |
TX | RX / RXI / RXD |
Warning: some adapters are mislabeled and have inverted RX/TX.
With a Teensy 2.0 or Arduino Leonardo as a USB dev board:
Arduino Leonardo | Teensy 2.0 | USB to UART board |
GND | GND | GND |
0 (RX1) | D2 | TX / TXO / TXD |
1 (TX1) | D3 | RX / RXI / RXD |
If you use the arduino on-board USB to serial converter, Rx and Tx are inverted, i.e. Rx = TX▶ and Tx = RX◀
Examples
- mislabeled CP2102 converter (left) to a Teensy 2.0 board (right)
- using jumper wires (these are generally provided with USB to serial TTL boards) in case your AVR USB board has header pins:
- Bumble-b and FT232RL wired on a breadboard:
- Teensy++ and CP2102 wired on a breadboard:
- Teensy 2.0 and CP2102 soldered:

GIMX adapter or Arduino-compatible atmega32u4-based boards
Using the GIMX loader tool
(easy method, recommended)
- Download the GIMX loader tool and unzip the archive.
- Right-click on the arduino.inf file and click on Install.
- Replace the atmega32u4.hex file with the one you which to load (the firmware included in the archive is the EMUG29PS4 one).
- Run loader.exe and follow the instructions.
Upon success a "Success! Press enter to exit." message should be displayed.
Using Avrdude
(hard method, not recommended)
- Download the Arduino Leonardo drivers and unzip the archive.
- Right-click on the arduino.inf file and click on Install.
- Make sure that the USB to UART board (e.g. CP2102) is connected and powered, and that the wiring with the atmega32u4 board is correct (see above GND->GND, TXD->RXD, RXD->TXD).
- Make sure that the atmega32u4 board is connected to your computer and powered.
- You should now have the atmega32u4 board connected via the USB-to-UART and via its on-board USB port
- Download the Arduino Builder tool and extract the archive (using 7zip).
- Open a command window (cmd) and change the current directory to the extracted ArduinoBuilder folder. e.g. cd "C:\Path\To\ArduinoBuilder\", or simply shift-right-click in windows file explorer and click "open command window here."
- Type the following text but don't press enter:
avrdude -p atmega32u4 -c avr109 -P COMx -D -U flash:w:<path to atmega32u4.hex>:i
- Make sure to replace "<path to atmega32u4.hex>" in the command line with the location of the firmware to load (for example: C:\Users\YourUserName\Downloads\firmwares-5.0\EMUPS4\atmega32u4.hex).
- Open the device manager, and expand the "Ports" item. You should see your USB-to-UART driver (e.g. CP2102) connected to a COM port and the Arduino connected to another COM port. *Neither* of these are the COM ports you're looking for, in all likelihood.
- Unplug/replug the atmega32u4 on-board USB (not the USB-to-UART) from your computer (doing this on the computer side rather than the Arduino side may be easier). When you replug it back in, watch the device manager, and notice which COM port is opened when the bootloader starts up. Ideally, this will be the same every time it is disconnected and reconnected. *THIS* is the COM port you want!
- Change the "x" in "COMx" in the above command to the number of the COM port that the bootloader uses.
- Unplug and replug the atmega32u4 USB again, and as soon the bootloader COM shows up, press enter to execute your command
- The bootloader is executed very briefly. You may have to make a few attempts before the firmware gets loaded correctly!
- If successful, avrdude should say "avrdude done. Thank you."
In GNU/Linux, the avrdude command is:
avrdude -p atmega32u4 -c avr109 -P /dev/ttyACM0 -D -U flash:w:atmega32u4.hex:i
(make sure to adjust the port and the file)
Teensy boards
Teensy boards can be easily flashed using the Teensy Loader.
It is only compatible with genuine teensy boards.
Other tools (DFU-compatible boards)
There are a few other tools that can be used to load the hex file:
- Flip utility from Atmel (not compatible with genuine teensy boards and with Arduino-compatible atmega32u4-based boards)
- dfu-programmer command-line tool (not compatible with genuine teensy boards and with Arduino-compatible atmega32u4-based boards)
dfu-programmer example:
sudo dfu-programmer at90usb162 erase sudo dfu-programmer at90usb162 flash at90usb162.hex sudo dfu-programmer at90usb162 reset
Serial port settings
This is needed on Windows, for USB to UART adapters based on a FTDI chip.
On Windows the driver for FTDI chips (e.g. FT232R, FT230X, FT231X...) provides a "Latency Timer" setting than should be set to 1ms for optimal performance.
The procedure is detailed on the FTDI website: link.
Next Tutorial
Now that your adapter is ready you can follow the instructions on the Quick Start page.
