I had a arduino Mega2560 collecting ds18 and dht22 data. I recently(Nov16) purchased a couple protons and the ShieldShield device with it in mind to fairly directly pull the Mega and shield stack out, and “slip” in the proton/shield shield. Even with knowlege of the pin mapping, I’m confused. I have re-written my (arduino) code to work within the Proton, using protoboard mounting of ds18s and dht22 components, jumper wiring to the proton pins. My bench setup worked fine. (I did not have a 2nd dht connected)
my arduino code set: … my proton code …field wire on Shieldpin:
dallas on D4 … … pin D6 … D4… parasite mode (edit)
DHTone on D2 …pin D2 … D11
DHTtwo on D3 …pin D3 … D12
The forum generally references the Shield Shield device with a Core device rather than a Proton device.
Is, in fact, the shield able to operate these Proton functions
Is the Proton not capable of supporting two channels (two different input pins, two different sessions) of DHT22 via adafruit_dht libraries?
The forum indicates that an early Shield Shield had Dallas ds18 issues. I assume that mine is an updated version. Has a ‘new’ version been issues, will it fix the ds18 issue, how can I tell if mine is the newest version.
Thank you for your assistance.
