Mydin-Class-TwoRelay3Mod
Pico3Mod class
Raspberry-Pi Pico based controler for 3 modules DIN case.
The implementation of the class is closely tied to the features of the backplane bpard
Features
Board schematic
Schematic shows how the hardware is wired to the connector.
Examples
The TwoRelay3Mod repository contains many useful examples.
Your knowledge will quickly progress by reading and understanding them.
The following example show how the din object offers the access to the various inputs/outputs of the backplane (the two relays in the present case).
from mydin import configure
from mydin.pico import Pico3Mod
from mydin.backplane.relays import TwoRelay3Mod
import time
din = configure( Pico3Mod, TwoRelay3Mod )
print( "Manipulate the relays" )
din.rel1.on()
print( "Rel1 is", din.rel1.value() )
time.sleep(1)
din.rel2.on()
print( "Rel2 is", din.rel2.value() )
time.sleep(1)
print( "All relays off" )
for relay in din.relays:
relay.off()
print( "relays state", [relay.value() for relay in din.relays] )

Class TwoRelay3Mod
Module relays
DIN Size 3 Modules
Descr Backplane with 2 relays (for 3 modules DIN case).
Attributes
out1, out2 : Pin
References to the Pin object controling the Relay. The object are created in the attach() method.
The names are identicals to those used on the controler connector.
 |
The instances are created by the configure() function. |
