I have many connected USB devices on my computer. Last night, I went to set the RTC "DS1307" on my Arduino "Teensy 2" and used the wrong comport. The Arduino driver directed the upload to my Espruino RTC instead. In doing so, it set the external I2C RTC "DS3231" to the wrong time!
How can my comport mis-direction make it so the Arduino IDE uploaded into the Espruino?
Next time, I will remove all devices which I am not uploading to.
