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.
@DrAzzy
Espruino presently does not have software serial functionality.
I remember Gordon having mentioned supporting this (along with possibly software I2C), as an extension of how we can currently do software SPI. UART is trickier though, because of the importance of timing, that the fact that you need to track the incoming data with interrupts.
Where does implementing software serial sit in the priority pile? I would consider it to be acceptable if the Espruino blocked while sending (and I guess receiving would be tricky too in this regard). I think it's fine if the software serial is gimped (low or limited baud rate options), we just need something.
The pico is kinda starved for serial ports, particularly now that we're using one of them to get internet - ST's decision to put UART6 on the same pins as USB is unfortunate....
