To communicate, you need to use software-based bit-bang signaling or insert a 1-wire line driver that connects with one available interface like SPI or I2C. In most cases, when the microcontroller is used, 1-wire devices are interfaced directly to MCU pin(s).

I want at least one more uart interface. Possible solutions: Bit banging: Use two unrelated spare GPIOs. I understand that timing is a problem on a standard linux. Would it be reliable with very low baudrate? Switching: RPI decides when to talk to which device. Using e.g. CD4066BC.

In computer engineering and electrical engineering, bit banging is a "term of art" for any method of data transmission that employs software as a substitute for dedicated hardware to generate transmitted signals or process received signals. Software directly sets and samples the states of GPIOs (e.g., pins on a microcontroller), and is responsible for meeting all timing requirements and protocol sequencing of the signals. In contrast to bit banging, dedicated hardware (e.g., UART, SPI WebEnhanced Asynchronous Bit Bang Mode with RD# and WR# Strobes - The FT232R supports FTDI’s BM chip bit bang mode. In bit bang mode, the eight UART lines can be switched from the regular interface mode to an 8-bit general purpose I/O port. Data packets can be sent to the device and they will be sequentially sent to the interface

WebIn contrast to bit banging, dedicated hardware (such as a modem, UART, or SPI) handles these parameters and provides a (buffered) data interface in other systems, so software is not required to perform signal demodulation.
