This repo is to be used from Linux command-line to program micro teleinfo modules. These module need to be programmed before the first use.

It will flash the FTDI module EEPROM with correct configuration and serial Number then check Serial communication receveid my Micro Teleinfo Module.

Test Theory

  • Plug USB Module
  • Flash default FTDI FT230X config to check communication between USB Computer (Raspberry PI) and Micro Teleinfo Module
  • Check RED Led
  • Check Serial Communication comming from Module Teleinfo input simulating sending data using Raspberry PI Serial Port
  • Flash final FTDI FT230X config (LED and device Serial Number)
  • Check Serial Number and GREEN Led

Test Tools

  • Rapsberry PI (2 or 3) installed with latest Raspbian Jessie Lite
  • 1 x 4Gb SD card to put Raspian Jessie Image
  • 2 x Dupond cable or build cable from dupond and Pogo Pins depending the best use you choose for testing
  • Test Software installed (this repo)
  • Some USB Micro Teleinfo to flash


Download and install the latest Raspbian Jessie Lite image. Look at the procedure here

Once installed plug you can work directly on the Raspberry PI connected with a monitor, keyboard and mouse but my favorite is to connect to Raspberry PI with ssh (PI need to be connected on you network either with RJ45 cable or WiFi) and work from my main computer.

To connect your PI to WiFi from command line, here is the procedure then you can log off and ssh to it with

ssh raspberrypi.local

So from now, assuming you are logged on the PI (locally or with ssh)

Use raspi-config to change serial settings with Advanced Options / Serial / and set No to "Would you like a login shell to be accessible over serial?"" You can also change your PI hostname.

If you have a Raspberry PI Version 3, Serial has changed. Check see this post but we need to have reliable Serial on /dev/ttyAMA0 as before, so we will use the hardware one using overlays to remap as follow Edit the file /boot/config.txt and add the following two lines at the end :


Then stop bluetooth service and reboot with

sudo systemctl disable hciuart
sudo reboot

Update your PI

sudo apt-get update
sudo apt-get upgrade

Install some prerequisites tools

sudo apt-get install build-essential gcc make libftdi-dev git-core python-serial

Install and build lastest usb_modeswitch

sudo apt-get install libusb-1.0-0-dev
bzip2 -d usb-modeswitch-2.5.0.tar.bz2
tar -xvf usb-modeswitch-2.5.0.tar
cd usb-modeswitch-2.5.0/
sudo make install

Then install and build the test tools

git clone
cd ftx_prog
chmod ug+x


Connect Raspberry PI P1 connector pin 6 (ground) and pin 8 (TXD) to Micro Teleinfo input connector (whatever wire order, no matter)



You just need to follow the procedure on te screen, enter 1st bach Serial Number at startup.

During flash and test RED led should be ON and after all is okay GREEN led should be ON
