Newbie I just bought a M5Stack Cardputer and I want use it with my Intel Mac but have run into difficulties immediatley as I cannot identify a com port that will allow me to enter other programs for evaluation. Also My Cardpiter shipped with Cardputer User Demo V1 but in M5 Burner I can only find Demo V0.9.1 and would welcome any advise on how to backup V1 so I could have the possibility of reinstalling it...if I ever establish how to communicate with the Cardputer using my Intel Mac. Looking forward in hopeful anticipation of some useful suggestions on how I should start.
