Using their supplied arduino core, I cant get their sample code to compile properly, or any code for that matter. A simple serial print with delay is all that will work and upload.

Is the ADC of the DFRduino M0 Mainboard a 12 bit ADC or a 10 bit ADC like the Arduino UNO ? Thanks a lot.

Hi there! Having problem with establishing the IIC communication between M0 Mainboard and Arduino Uno. Using "Wire" Library, tried connecting via multiplexed SDA, SCL pins and 2,3 pins. Cant find any guide at your wiki.dfrobot.com. Scanning from Uno shows 0 devices found, changing roles and scannicg from M0 shows 112 devices found
Arduino IDE v 1.8.12, M0 v 1.0.3

Please check if the PC and M0 COM can be connected normally. Please send a detailed screenshot of the usage information to the email address ([email protected])

At the end of the installation guide, and I try to upload the program to the microcontroller, this fails

Then I guess you will have to write/find interrupt library for it. Sorry for the inconvenience.

I am having trouble with the DFRduino M0 attachInterrupt function, which I have used successfully with many other Arduino variations. I also see the digitalPinToInterrupt function is not implemented. Are there any newer support files or has anyone been able to get Interrupts to work?

Will it be possible to work with this microcontroller in MindPlus environment?

Under arduino preferences I shut off "Aggressively cache compiled core". This seemed to fix the issue.
