P1AM-ETH

The P1AM-ETH uses SPI to communicate with the P1AM-100 or other MKR format CPU.
For Arduino use the P1AM-ETH uses the Arduino Ethernet library which comes standard with the Arduino IDE.
For CircuitPython the P1AM-ETH uses the WIZNET5K library which comes installed on the board or can be downloaded here.

Code Examples

The webserver example redefines the function of pins A3 and A4 which are used by the Base Controller. To use the webserver example provided by Arduino with the P1AM-100 you must first add the following if statement after the start of the for loop that increments through analog channels.

for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
				    	if(analogChannel != 3 || analogChannel != 4) {	//add this line to skip over A3 and A4 when calling analogRead on Arduino pin analog inputs
				        	int sensorReading = analogRead(analogChannel);
				        	client.print("analog input ");
				        		client.print(analogChannel);
				        		client.print(" is ");
				        		client.print(sensorReading);
				        	client.println("<br />");       
				    	}
				}
				

ViewMarq

The ViewMarq library allows easy connectivity between the P1AM-100, P1AM-ETH, and a ViewMarq LED message sign. Find the code and examples in the Arduino Library Manager or clone it from GitHub

ViewMarq LED message signs can be purchased here from AutomationDirect.com

This example creates a server listening on port 50007 which echoes back any messages received

import board
import busio
import digitalio
from adafruit_wiznet5k.adafruit_wiznet5k import WIZNET5K
import adafruit_wiznet5k.adafruit_wiznet5k_socket as socket

cs = digitalio.DigitalInOut(board.D5)
spi_bus = busio.SPI(board.SCK, MOSI=board.MOSI, MISO=board.MISO)

# Initialize ethernet interface
eth = WIZNET5K(spi_bus, cs, is_dhcp=True)

# Initialize a socket for our server
socket.set_interface(eth)
server = socket.socket()  # Allocate socket for the server
server_ip = eth.pretty_ip(eth.ip_address)  # IP address of server
server_port = 50007  # Port to listen on
server.bind((server_ip, server_port))  # Bind to IP and Port
server.listen()  # Begin listening for incoming clients

while True:
    print(f"Accepting connections on {server_ip}:{server_port}")
    conn, addr = server.accept()  # Wait for a connection from a client.
    print(f"Connection accepted from {addr}, reading exactly 1024 bytes from client")
    with conn:
        data = conn.recv(1024)
        if data:  # Wait for receiving data
            print(data)
            conn.send(data)  # Echo message back to client
    print("Connection closed")
