Just tested my educational template for ‘Penguin Crossing’ (Zebra Crossing) that uses:

  • pins 19,21,23 = R,Y,G LEDs
  • pin 18 = Piezo 3 Volt buzzer
  • Pins 24,26 = ‘Call Buttons’ from either side of the street
    The default Pi / Rasparian Epiphany web browser did not work but IceWeasel installed from terminal on the desktop and ran nicely.
    Thanks !

(first) Questions:

  • What is ALT0 (presume initial state of Pi / WebIOPi pin state on boot ?)
  • Is the UART on the GPIO ttyAMA0 already set up or are the usual tweakes needed to the boot and Getty ?

Hey Andrew

  • You are not supposed to see ALT0, can you post a picture and tell what Pi version do you use ?
  • UART activation is not possible from the dashboard yet, and still need manual tweak to boot and getty conf

Will do if I see it again… Suspect may be slowwwwwwwwness of things here ‘down under’
I have a student coming in to set up some boxes for looking at things / gui displays on a range of OS

Here is screen capture of GPIO from this morning.

Note the scattering of ALT0. Am I supposed to be seeing these ?
I am still having issues making any GPIO header pin DI, DO work.

  • Changing a pin to IP / OP state takes 5 to 10 attempts
  • Setting/clearing a pin is less than 1 in 20 attempts
    Plenty of pink “error sending command messages”

This and not being able to Add or setup a GPIO pin device for the last week or so. Should I do a reformat and start a scratch install ?

@svazir andrew’s issue is related to SPI/I2C enabled in Raspberry Pi but not using it.
Would be solved by fixing I2C/SPI setting in the Pi configuration from the dashboard.

Just to clarify… So If I am NOT using any i2C then turn off toggle in settings ?

I would say there’s no need to touch the settings at this point :slight_smile: We enable everything for you upon install.
