Yet Another Pi Zero Portable!!
-
Would I be able to ssh and terminal? Would I use the command 'sudo nano raspiconfig.txt'? Or could I just put my sd card into my linux laptop and edit the config file that way?
-
Oh and one last question (I think!), I have a switch like the ones you used for the controller, where would I put that in the circuit so it powers both the pi and the screen on? I don't mind if it doesn't power it off as I can just select the shutdown option in emulation station
-
@gazredtyke you need to type
sudo raspi-config
On the pi, this will let you change the "system settings" on the pi
The switches I used on the controller part are momentary switches, they only stay "on" for as long as it is pressed. You will need something more like a latching switch or a side switch
-
@moosepr Thanks, and where in the circuit would that go?
-
@gazredtyke you would need it between the power and the pi. The screen gets its power from the pi, so once that is off, the screen is off too
-
@moosepr I haven't got a switch at the moment so for the time being I'll just twist the wire together, I've done the raspi-configuration step but couldn't find where to enable device tree, any ideas?
-
@gazredtyke I think there was one item i couldnt find myself, If you try the next step anyway, see how you get on
-
@moosepr I tried the next step but got an error message
-
@gazredtyke whats the error? it could be that i have done a typo :P
-
@moosepr can't remember, I'll have to try again when I get in from work
-
@gazredtyke try this command instead
sudo modprobe fbtft_device name=adafruit22
-
@moosepr would it be adafruit28 as my tft is 2.8"?
-
@gazredtyke I think it will be the 22. i cant see a 2.8 device listed on the driver wiki, in theory the 2.2, 2.4, and 2.8 inch screens are all identically internally, they just have different sized pixels
-
@moosepr The error message is "could not insert 'fbtft_device' : Invalid argument'
-
@gazredtyke I will have to get mine hooked up to a keyboard and see what I typed to get it going, it's been a while...
-
@gazredtyke try
sudo modprobe fbtft_device name=fb_ili9340
-
@moosepr still getting the same error mate, as I say though I couldn't find how to enable device tree
-
@gazredtyke I have just looked on mine and i dont think i could find the device tree bit, i sure cant now!! have you enabled the SPI?
-
@moosepr can you show a diagram of which gpio pin layout you followed? Maybe that's the issue?
-
@gazredtyke the error seems to suggest that it doest like the options being passed into the fbtft device call. my command scroll back doesnt go far enough back to see my initial testing bits. I need to go back to a fresh install of retropie and follow it all from the beginning.
If my new 2.2" screens ever come from china, i will be setting up another pi and will detail the lot
