for 4B, also need "bus = smbus.SMBus(1)"

[shenlijun]

somewhere like this need to be modified

if rev == 2 or rev == 3:
bus = smbus.SMBus(1)
else:
bus = smbus.SMBus(0)

This was part of the original argon1.sh script.

But I'm not sure I get what you mean. Should the if be extended with a new rev? like rev == 4? I don't have access to a 4B so I cannot check myself. Would you mind clarifying a bit?

rev doesn't mean the raspberry pi revision but the gpio board layout revision. There is no change required for the raspberry pi 4B
