Emonpi auto reflash

If you have installed the Emonpi image on your Raspberrypi and have connected the RPICT card on it then there are big chances the RPICT firmware has been wiped out.

To confirm this is the case install the lcl-show-header.py utility with the commands below.

wget lechacal.com/RPICT/tools/lcl-show-header.py.zip
unzip lcl-show-header.py.zip
sudo mv lcl-show-header.py /usr/local/bin/

Then run it with

lcl-show-header.py

If the RPICT firmware has been modified you will se the following message.

To fix this you will have to restore your original firmware. For this install avrdude as explained in the link below.

Upload_Arduino_sketch_from_Raspberrypi_to_RPICT

Then download the latest firmware

wget http://lechacal.com/RPICT/sketch/RPICT_MCP3208_v3.2.0.ino.hex

then upload it to the RPICT

lcl-upload-sketch.sh RPICT_MCP3208_v3.2.0.ino.hex

After that you should restore the factory configuration. You should have received a 4 letter code with the RPICT card. We will assume TKPJ in teh example below.

Get the configuration:

wget lechacal.com/hardware/c/TKPJ.conf

Write it

lcl-rpict-config.py -a -w TKPJ.conf
