Hey everyone!
I just want to simulate an uart device on the host pc to test my code locally.
I’m using tty0tty to simulate the uart interface.
My code so far:
defmodule UartSimulator do
use GenServer
@path_tty0tty "/bin/tty0tty"
def start_link() do
{:ok, pid} = GenServer.start_link(__MODULE__, %{})
end
def init(state) do
tty0tty = Port.open({:spawn, path_tty0tty}, [:binary])
port = File.open!("/dev/pts/2", [:write])
{:ok, %{state | tty0tty: tty0tty, port: port}}
end
def handle_cast({:data_reporting_mode, mode, activity}, %{port: port} = state) do
IO.binwrite(port, "hello world")
{:noreply, state}
end
end
Is this the way to go?
And how can I implement this module in my testing environment? I’m getting the error that the module is not available.
