How to get more than one uart interface
Ok, I have one uart interface (TXD GPIO 14, RXD GPIO 15). I want at least one more uart interface.
Possible solutions:
Bit banging:
Use two unrelated spare GPIOs. … CD4066BC.
spi to 2 x uart bridge:
Didn't find a suitable part (availability, price, dil package)
usb to uart:
Expensive
Are there other options? I'm inclined to switching, if it can be done. …
