Getting the OpenBeacon Tag firmware

OpenBeacon Tag related firmware source may be found on our server for occasional browsing (pic16tag Firmware) and for development purposes in our git repository:

 git clone http://www.openbeacon.org/openbeacon.git

Compiler Installation

PIC16F684 Microcontroller from Microchip on the OpenBeacon Tag

Download the HI-TECH C for the PIC10/12/16 MCU Family compiler at http://www.microchip.com. Registration at Microchip seems to be mandatory for that.

Unpack the download archive:

mkdir -p ~/Install
cd ~/Install
unzip ~/Downloads/HCPIC-pro_9_80-linux.zip

You now should have the installation file in that directory which you can execute using sh.

ls -l              # verify if file is there
-rwxr-xr-x. 1 meri meri 8691338 13. Aug 01:25 picc-pro_9.80.6738-linux.run
su                 # switch to root user for further installation
sh ./picc-pro_*.run  # run setup as root

Please setup as follows:

==> Do you accept the terms of the licence agreement? [y/n] y
==> Please enter the installation directory [/usr/hitech/picc/9.80]: 
==> Please enter Serial Number, demo or lite: HCPICP-demo

Leave root mode:

exit

Add path to your startup scripts

gedit ~/.bashrc

Add the following line at the end - make sure to adjust to your actual compiler version:

export PATH=$PATH:/usr/hitech/picc/9.80/bin

To make the changes effective you need to close your current terminal and open a new one.

exit

Programmer installation

PICkit2 USB programmer with six pin 2.54mm header attached

Cut your own six pin 2.54 header and insert into PICkit2 programmer to re-flash tags

At PICkit 2 Development Programmer/Debugger please scroll down to Linux & Mac OS X Software (Unsupported) and download PK2CMD V1.20 Linux Kernel 2.6 Executable Binary.

Example installation process:

mkdir -p ~/Install
cd ~/Install
wget http://ww1.microchip.com/downloads/en/DeviceDoc/pk2cmdv1-20Linux2-6.tar.gz
tar -xvzf pk2cmdv1-20Linux2-6.tar.gz
cd pk2cmdv1-20Linux2-6
su                 # switch to root user for further installation
install *.dat pk2cmd /usr/local/binexit               # switch back to normal user

If you get a No PICkit 2 found. error message, you need to allow access to the programmer to non-root users. Please create a file called pickit.rules at /etc/udev/rules.d/ as root user.

Verify first if the programmer is connected:

lsusb -d 04d8:Bus 002 Device 039: ID 04d8:0033 Microchip Technology, Inc.

Now create /etc/udev/rules.d/pickit.rules :

echo 'SYSFS{idVendor}=="04d8", SYSFS{idProduct}=="0033", MODE="0666"' >> /etc/udev/rules.d/pickit.rules

Please unplug and re-plug your programmer before running pk2cmd again.
