Adding another UART

Can something like this be done on the Photon?

Or does anyone know of an SPI/I2C to UART bridge?

You mean like this?

This is not really a SPI/I2C-UART bridge but sounds similar to the intent of the link.

Cheers, that would do it, from other searches I’d done ppl were saying that you couldn’t do software serial on the photon because of the precise timing and interrupts would interfere with the background processes.

Hence I wrote this library to fill the gap but this is limited to baudrates bellow 36000 for the reason of the interrupt latency impact.
