Install Arduino on Buster
- Arduino 1.8.12 (or higher) from arduino.cc – Software – Arduino ARM 32 bits
- Download to e.g. Downloads
- cd /Downloads
- tar -x -f arduino-1.8.5-linuxarm.tar.xz
- cd arduino-1.8.12
- sudo ./install.sh
- and Arduino appears in Home – Programming desktop
sudo apt-get install minicom
setup your system to auto ;login into a commandline session
[use sudo raspi-config]
then at the end of .bashrc put in
if [ $(tty) == /dev/tty1 ]; then
minicom -s ##change this to be the thing you want or even a script [full path to]
then reboot your rpi
Shutdown menu not working:
You can get the Buttons working, just change the line ‘Logout=lxde-pi-shutdown-helper’ to ‘Logout=sudo lxde-pi-shutdown-helper’
For Buster see here!
Installed using instructions from several posts by Thaddy as follows:
1. Add stretch-backports to sources.list
Create: sudo nano /etc/apt/sources.list.d/backports.list
Add: deb http://ftp.debian.org/debian stretch-backports main
Update: sudo apt-get update
Ignore complaints about not signed
2. FPC 3.0.4 and Lazarus 1.8.4 are both in stretch-backports
Use apt or apt-get, need to install with the -t option.
Answer Y to install without verification.
sudo apt-get -t stretch-backports install fpc
sudo apt-get -t stretch-backports install lazarus
Ignore complaints about not verified
he simplest way to set up a “pushbutton to shut down” is to add “dtoverlay=gpio-shutdown” to /boot/config.txt and rig a NO momentary contact switch across pins 5 and 6. Push once to shut down the system. Push again to reboot it.
To avoid I2c being unusable:GPIO26 is physical pin 37
pi@raspberrypi:~ $ dtoverlay -h gpio-shutdown
Info: Initiates a shutdown when GPIO pin changes. The given GPIO pin
is configured as an input key that generates KEY_POWER events.
This event is handled by systemd-logind by initiating a
shutdown. Systemd versions older than 225 need an udev rule
enable listening to the input device:
ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
This overlay only handles shutdown. After shutdown, the system
can be powered up again by driving GPIO3 low. The default
configuration uses GPIO3 with a pullup, so if you connect a
button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
you get a shutdown and power-up button.
Params: gpio_pin GPIO pin to trigger on (default 3)
active_low When this is 1 (active low), a falling
edge generates a key down event and a
rising edge generates a key up event.
When this is 0 (active high), this is
reversed. The default is 1 (active low).
gpio_pull Desired pull-up/down state (off, down, up)
Default is "up".
Note that the default pin (GPIO3) has an
The default GPIO is 3 (which appears on pin 5 of the 40-pin header). The pin is configured to pull high by default (which is also the SoC's default), and the GPIO is marked as active low (the opposite to the pull, for obvious reasons).
If you are having trouble, you can debug using raspi-gpio on Raspbian. Assuming for now that the overlay applied correctly (lsmod should show gpio-keys as being loaded), raspi-gpio get 3 will show the pin level (which should be 1) and function (INPUT). Now run it in a loop:
pi@raspberrypi:~ $ while true; do raspi-gpio get 3; done
Attach one end of a patch lead to pin 5 (GPIO3), and touch the other end on pin 6 (GND) - the Pi should shut down immediately, but if not you will see the pin level change to 0.
