[Solved] 5 RELAY Units on M5Stack device
-
Hi folks
I have played around a bit with some relay units, but I cant find a way to connect 5 units to my M5Stack unit.
I have tried:
- to connect them all to same port via splitters
- to connect them all via Pa.HUB-Unit
- to connect them all via Pb.HUB-Unit
It does not work.
Does anyone have an idea or has everyone done it?
Thanks very much

You have to use the Pb-Hub unit, black connector of the relay units to the black connectors of the Pb-Hub (for analog and/or digital input/outputs, e.g. realys) . The Pa-Hub is used connecting i2c units (red connectors) with the same i2c address (e.g. to environment units).
You can programm the 6 channels (analog or digital, equivalent to multiple Core-B channels) of the Pb-hub using blockly.
good luck crami25

Thank you crami25
I thought that I have to use the RELAY-Unit-Component and the PbHub.Unit-Component simultaneously in UIFlow.
But as you told me, I just have to set the Outputs on the PbHub to 0 oder 1 :-)
No need of the RELAY-Unit-Component in software.from m5stack import * from m5ui import * from uiflow import * import unit setScreenColor(0x222222) pbhub0 = unit.get(unit.PBHUB, unit.PORTA) while True: pbhub0.digitalWrite(0, 0, 1) wait_ms(100) pbhub0.digitalWrite(1, 0, 1) wait_ms(100) pbhub0.digitalWrite(2, 0, 1) wait_ms(100) pbhub0.digitalWrite(3, 0, 1) wait_ms(100) pbhub0.digitalWrite(4, 0, 1) wait(1) pbhub0.digitalWrite(0, 0, 0) wait_ms(100) pbhub0.digitalWrite(1, 0, 0) wait_ms(100) pbhub0.digitalWrite(2, 0, 0) wait_ms(100) pbhub0.digitalWrite(3, 0, 0) wait_ms(100) pbhub0.digitalWrite(4, 0, 0) wait(1)
Great it works!
