PIGPIO raspbian 31-01-2015

[kiloleader]

Hi all,

Does anyone know if PIGPIO runs on the latest raspian. I am using a model B+ (not a 2) and have had pigpio running quite happily. I have now upgraded to the 31-01-2015 release of Raspian and I get the following error when trying to run my program:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Can't connect to pigpio on localhost(8888)

Did you start the pigpio daemon? E.g. sudo pigpiod

Did you specify the correct Pi host/port in the environment
variables PIGPIO_ADDR/PIGPIO_PORT?
E.g. export PIGPIO_ADDR=soft, export PIGPIO_PORT=8888

Did you specify the correct Pi host/port in the
pigpio.pi() function? E.g. pigpio.pi('soft', 8888))

I have tried typing in the terminal:
export PIGPIO_ADDR=soft
export PIGPIO_PORT=8888
sudo pigpiod
to start the deamon before running my program but same result.

I have changed my program from:
pigpio.pi()
to:
pigpio.pi('soft', 8888)
with no avail.

Any thoughts?

The 31-01-2015 firmware may be the one which had timing problems although I wasn't aware that confused pigpio.

I'd try a sudo rpi-update to get the most recent firmware.

Update:

I have tried:
pigs t
pigs pigpv
pigs hwver
in the terminal, all return socket connection failed.

Also, cat /dev/pigerr& returns:
[1] 18077

I then tried:
sudo killall -USR2 pigpiod
sudo killall -USR2 pigpiod
sudo killall -USR2 pigpiod
sudo killall -USR2 pigpiod
sudo killall -USR2 pigpiod

sudo killall -USR1 pigpiod
sudo killall -USR1 pigpiod
sudo killall -USR1 pigpiod
sudo killall -USR1 pigpiod
sudo killall -USR1 pigpiod
sudo killall -USR1 pigpiod

after which typing:
./x_pigs
./x_pipe
both returned
bash: ./x_pigs (or pipe): no such file or directory.

I'm not sure what you are doing.

To use pigs and the Python module the daemon need to be running.

To start the daemon try these commands

sudo killall pigpiod # just in case it's already running, won't do any harm

sudo pigpiod

Then try

pigs pigpv
pigs hwver

I am having the same error, I have posted a question on the stackexchange forum for rpi here:https://raspberrypi.stackexchange.com/q ... al-rpi3%20
