Device #1

This example show how possible control Arduino PINs (transmit-receive) via router_RxTx_bus1 or send messages to RPi/PC via router_Tx_bus2

This device connected to router_RxTx_bus1 and router_Tx_bus2 via SoftwareBitBang strategies (see diagram)

Examples

Examples of request <-> response (RPi/PC <-> Arduino)

Note: from RPi/PC side uses python client: pjon_grpc_client.py

Read Hardware Digital PIN (digitalRead(13)):

$ ./pjon_grpc_client.py 1 21 H-13
Client received: H-13>0

Read Hardware Analog PIN (analogRead(14)):

$ ./pjon_grpc_client.py 1 21 H-14
Client received: H-14>275

Write Hardware Digital PIN (digitalWrite(13, 1)):

$ ./pjon_grpc_client.py 1 21 H-13-1
Client received: H-13-1>1

Read Virtual PIN:

$ ./pjon_grpc_client.py 1 21 V-0
Client received: V-0>0

Write Virtual PIN:

$ ./pjon_grpc_client.py 1 21 V-0-1
Client received: V-0-1>1

Read again the same PIN (after write):

$ ./pjon_grpc_client.py 1 21 V-0
Client received: V-0>1

Make test, number in response will be increased on 1:

$ for i in $(seq 1 2); do ./pjon_grpc_client.py 1 21 N; done
Client received: N>1
Client received: N>2

Wrong command:

$ ./pjon_grpc_client.py 1 21 T
Client received: T>wrong command

Example of sending messages (Arduino -> RPi/PC)

Note: from RPi/PC side for receiving messages uses python script: pjon_grpc_clientserver.py

Enable sending messages every 1 second from Arduino to RPi/PC:

$ ./pjon_grpc_client.py 1 21 M-1
Client received: M-1>1

On RPi/PC side we should see:

$ ./pjon_grpc_clientserver.py
Client-Server received: node_id=21, data=<Message every 1 sec: 1
Client-Server received: node_id=21, data=<Message every 1 sec: 2
Client-Server received: node_id=21, data=<Message every 1 sec: 3
...

Enable sending messages every 0.2 second from Arduino to RPi/PC:

$ ./pjon_grpc_client.py 1 21 F-1
Client received: F-1>1

On RPi/PC side we should see:

$ ./pjon_grpc_clientserver.py
Client-Server received: node_id=21, data=<Message every 0.2 sec: 1
Client-Server received: node_id=21, data=<Message every 0.2 sec: 2
Client-Server received: node_id=21, data=<Message every 0.2 sec: 3
