LCD pypilot hat

[gildas declercq]

Hi all,

I have so far only tried to connect the hat on the rpi and the moter controller to DC current to make some tests.

nothing shows up on LCD.
there is some lights so it looks like getting current.
but nothing on the screen.

at what step should I see something ?

how can I test it, like with command line ?

thanks a lot

For the display to be used by pypilot, the pypilot_hat service must be running.

you could even invoke it from the command line but eventually
sudo service pypilot_hat enable

Hi,

I have the same problem, the LCD screen emits a light but displays nothing. I've tried fiddling with pypilot_hat, its configuration .pypilot/hat.conf and the settings on port 33333, with no success. Maybe I messed it up by touching everything ...

Make sure you have an up-to-date openplotter 3 so that the pypilot_hat service is available.

Maybe the wrong driver then? Did you find the driver in hat.conf? It is possible the eeprom is misprogrammed in which case you could override the driver to jlx12864 and the display should work.

Hi , sorry for late reply,

sudo service pypilot_hat enable
return
pypilot_hat : unrecognized service

---

ok just os version
sudo systemctl enable pypilot_hat

return nothing so it seems ok

localhost:33333
is not working.

what could I add in hat.conf ?

i did some screen shots
running pypilot
   

when i click
"configure" this is the result of localhost:33333

any idea on log to check or command I could send to the LCD at least to make sure it can display something and is not just broken ?

thankx

Hi Sean 

I don't see any driver in the hat.conf 
pi@openplotter:~/.pypilot $ cat hat.conf
{"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"}}

what should I see in that .conf ?

Did you enable SPI in the raspbian config?
