I want to use a little screen with my raspberry, but I need to set the size correctly.
I should enter this into a config.txt
Full documentation on this: https://learn.adafruit.com/adafruit-5-800x480-tft-hdmi-monitor-touchscreen-backpack/raspberry-pi-config
# uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment this if your display has a black border of unused pixels visible # and your display can output without overscan #disable_overscan=1 # uncomment the following to adjust overscan. Use positive numbers if console # goes off screen, and negative if there is too much border #overscan_left=16 #overscan_right=16 #overscan_top=16 #overscan_bottom=16 # uncomment to force a console size. By default it will be display's size minus # overscan. #framebuffer_width=1280 #framebuffer_height=720 # uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1 # uncomment to force a specific HDMI mode (here we are forcing 800x480!) hdmi_group=2 hdmi_mode=87 hdmi_cvt=800 480 60 6 0 0 0 hdmi_drive=1 max_usb_current=1 # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes #hdmi_drive=2 # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display #config_hdmi_boost=4 # uncomment for composite PAL #sdtv_mode=2 #uncomment to overclock the arm. 700 MHz is the default. #arm_freq=800 # for more options see http://elinux.org/RPi_config.txt
I just pushed this config.txt to the raspberry via resin. But it does not change anything. Is this even the correct config.txt?
Or where does it have to go?
Additionally: I want to force the raspberry to output Audio via the 3.5mm Jack and not via HDMI. Normally I would just use
raspi-config on normal raspberry, but on a resinified raspberry I am not able to do that.
Thanks in advance
I think I acutally managed to force audio to the jack instead of HDMI by adding
amixer cset numid=3 1
to the config.txt file. So I assume the raspi-config is only available by writing the flags into the config.txt.
But anyway, I still did not manage to get the screen to work… If someone sees an important thing I am overseeing, please feel free to tell me :).
