still trying to update firmware hit the zip button,unzip,file in downloads.where is the download to sd file?Label says master open sprinkler.Very unclear on the the tinyusb solution for windows 7 64 bit.I’m close to to 500$ invested transferring my system to open but still lose connection occasionally.No explanation for the bar icon on the lcd display what does the x by the bars mean?where should the usbtiny files be located ?A run once any program feature is a must as is different runtimes within a program.A little better direction for github,the menu always has multiple choices. thanks richard
