enabling pypilot HAT service

[seandepagnier]

i am really sorry guys... i am having medical problems i am so out of touch. i have had good success with the code and merged to master but without testing every configuration. i should have pushed to beta branch for next time.

i tried to push a fix to the firmware issue

I'm sorry to read that, I hope you recover soon.

Hi, I have exactly the same problem. Fried my Pi4 by connecting it directly to 12vDc (oops). Downloaded the latest OpenCPN image into a new Pi4 and then updated Pypilot.  There was no hat.conf file in home/pi/.pypilot.  I copied in an old hat.conf but got the same error messages when I run pypilot_hat. So I cannot use the buttons I have wired to GPIO (I do not have a HAT fitted).  Is it possible to just run the GPIO and web interface on 33333?  Does anyone have a hat.conf file that works with the latest pypilot version?
Cheers
David

I have tried everything I can think of (including reloading pypilot from github and from OpenCPN) but cannot get pypilot_hat to run either directly or as a service. I tried with no hat.conf and tried with a hat.conf file I copied from the forum:

{"host":"localhost","actions":{"auto":[],"menu":[],"port1":[],"starboard1":[],"select":[],"port10":[],"starboard10":[],"tack":[],"dodge_port":[],"dodge_starboard":[],"engage":[],"disengage":[],"1":[],"-1":[],"2":[],"-2":[],"5":[],"-5":[],"10":[],"-10":[],"compassmode":[],"gpsmode":[],"windmode":[],"truewindmode":[],"center":[],"tackport":[],"tackstarboard":[],"none":[],"pilot_absolute":[],"pilot_basic":[]},"pi.ir":true,"arduino.ir":false,"arduino.nmea.in":false,"arduino.nmea.out":false,"arduino.nmea.baud":4800,"lcd":{},"hat":{"lcd":{"driver":"default","port":"\/dev\/spidev0.0"},"lirc":"gpio4"}}

But I just get:

pi@openplotter:~/.pypilot $ sudo pypilot_hat
hat start 9252.581509633
have gpio for raspberry pi
hat import done 9252.631372467

Any help would be much appreciated!

I also ran pypilot_hat without the sudo and got:

pi@openplotter:~/.pypilot $ pypilot_hat
hat start 9607.944609552
have gpio for raspberry pi
hat import done 9607.997461213

Good news: I managed to get it working! I disabled the lines that were causing the error above in hat.py at line 502

# if self.client and not 'modes' in self.config:
# values = self.client.get_values()
# if 'ap.mode' in values:
# self.config['modes'] = values['ap.mode']['choices']

This allowed hat to run and generate a default hat.conf:

{"host":"localhost","actions":{"pilot basic":[],"pilot absolute":[]},"arduino.adc_channels":[],"pi.ir":true,"arduino.ir":false,"arduino.nmea.in":false,"arduino.nmea.out":false,"arduino.nmea.baud":4800,"lcd":{},"hat":{"lcd":{"driver":"default","port":"\/dev\/spidev0.0"},"lirc":"gpio4"},"modes":["compass","gps","nav","wind","true wind"]}

I then re-instated the original hat.py and enabled pypilot_hat as a service. All now working OK with web page on 33333 so I can set up the gpio push buttons.

Thanks for reporting this. I have corrected the code and will test and push it soon.
