Ok, by looking at Qwiic shield schematic and reading the Wire library for MEGA types, I can succesfully connect after jumping A5 on the shield to 21 on MEGA and A4 on the shield to 20 on MEGA. Basically it seems Qwiic is designed for something other than MEGA, but work around is easy.
I'm having trouble getting example1 to work.
myScale.begin returns false. Which wiring is at fault? The I2C wiring or the load cell wiring?
I'm using elegoo MEGA2560 R3 with a Qwiic shield board an a Qwiic cable to the Qwiic scale.
I've removed the load cell wiring from the spring terminal and reinserted many times, trying to follow the recommendations in the hook up guide.
No public wish lists :(
