Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Good question. I have not looked into the serial driver myself. Given that you currently need uart0 to talk to the espruino interpreter, which serial port are you hoping to use? Uart1 only has TX, no RX. (And perhaps esp-link is a better match for what you need?)
