| + | When I run the PiPhi script or any of the LCD examples, I get an “'lcd' is not defined” error message. |
| + | The PiPhi script must be run as root in order to access the LCD and keypad hardware: |
| | | |
| + | <nowiki>sudo python PiPhi.py</nowiki> |
| | | |
| + | If that doesn’t fix it, check for any solder bridges or cold joints on the LCD plate, and make sure the headers between the plate and Raspberry Pi are aligned. |
| + | |
| + | Or the code may be having difficulty accessing the I2C bus. We can override this manually if the need arises. Edit PiPhi.py, looking for this line: |
| + | |
| + | <nowiki>lcd = Adafruit_CharLCDPlate()</nowiki> |
| + | |
| + | Et ajouter simplement ce paramètre: |
| + | |
| + | <nowiki>lcd = Adafruit_CharLCDPlate(busnum=1)</nowiki> |
| + | |
| + | Run the code again and see if that helps. |
| + | The Raspberry Pi does not boot when the LCD/Keypad Pi Plate is attached. |
| + | Check for any solder bridges or cold joints on the LCD plate, and make sure the headers between the plate and Raspberry Pi are aligned. |
| + | A keyboard attached to the Raspberry Pi is not responding. |
| + | Some keyboards require more power than the Raspberry Pi USB port can provide. Add a powered USB hub, or try a different keyboard if you have a spare. |
| + | The system never connects to the wireless network. |
| + | Most likely a typo during the wireless setup procedure. Go through each step on the “Initial System Configuration” page and check spelling carefully, including your wireless network name (SSID) and password. |
| + | |
| + | “Hidden” WiFi networks are particularly fussy, and even with the extra directions provided might not connect. We very strongly recommend using a broadcast network name. If using a hidden network…when creating the file wpa_supplicant.conf, did you remember to change the SSID and password to the values used by your network? |
| + | |
| + | It might also be an incompatible USB wireless adapter. The one in the Adafruit shop is known to work with the Raspberry Pi. |
| + | The PiPhi script just hangs at “Receiving station list…” |
| + | The pianobar application is most likely failing to connect to the Pandora server…probably due to an incorrect email address and/or password. Check the settings in the configuration file and make sure these match your Pandora credentials, not the account on your Raspberry Pi. |
| + | |
| + | If in doubt, run pianobar directly from the command line first. Once that’s working, then move on to the PiPhi script. |
| + | pianobar (or the PiPhi script) is running, but no sound is coming from the headphone jack. |
| + | Make sure audio is routed to the headphone jack rather than the HDMI port. From the command line: |
| + | |
| + | sudo amixer cset numid=3 1 |
| + | When pianobar tries to connect, I get a “TLS handshake error” message. |
| + | Enter the following command (as a single line — copy and paste verbatim, if possible): |
| + | |
| + | <nowiki>fingerprint=`openssl s_client -connect tuner.pandora.com:443 < /dev/null 2> /dev/null | openssl x509 -noout -fingerprint | tr -d ':' | cut -d'=' -f2` && echo tls_fingerprint = $fingerprint >> ~/.config/pianobar/config</nowiki> |
| + | |
| + | Essayer à nouveau. |
