Wegmatt dAISy HAT - Configuring Raspberry Pi for dAISy HAT; Recent Raspian Configuration; Older Raspian Configuration (Pi 1;2;Zero)

Use this information to configure OpenCPN or other programs. Keep in mind, that only one application
at a time can consume serial data.
You can verify the serial connection with a serial terminal program like for example screen. You may
have to install screen first by running:
sudo apt-get install screen
With screen installed, connect to the dAISy HAT with
screen /dev/serial0 38400
If the serial port is properly configured, pressing ESC will bring up the configuration and debug menu.
Pressing ESC again will return dAISy into receive mode. Exit screen by pressing CTRL-A, then K and then
Y.
3.2 Older versions of Raspian – Raspberry Pi, Pi 2 and Pi Zero
Older versions of Raspian require more manual steps to reconfigure serial ports.
If you have a Raspberry Pi, Raspberry Pi 2 or Raspberry Pi Zero, follow the steps outlined in the tutorial
for the Adafruit GPS HAT.
