Hi, In this case you just use spi_bufTx[0] = 0; If you wanted e.g. SPI_MODE = 2 and LSBFIRST, you would use spi_bufTx[0] = 2 | 8; In other words, the first 2 bits define mode, the 3rd bit defines CS behavior, the 4th defines LSB etc. CS signal is controlled by operating system.
This post describes how you can connect multiple Arduinos together via an RS485 connection. This is useful in situations where you need to connect devices together over longer distances than I2C or SPI can handle.
RS-485 systems that run over long distances and connect multiple systems are especially susceptible to these events. Isolating the RS-485 system devices from each of the systems connected to the bus prevents ground loops and electrical surges from destroying circuits. Isolation prevents ground loops...
7. i2C. An example of using i2C can be found on the ADC section. Here we show another example using the BlinkM RGB i2C controlled led. BlinkM uses a high quality, high power RGB LED and a small AVR microcontroller to allow a user to digitally control an RGB LED over a simple i2C interface.
I2C (Inter‐Integrated Circuit) I2C As with SPI a master‐slave system. Wednesday, May 15, 2019 13 I2C (Inter‐Integrated Circuit) I2C write a single byte 1. All: allow SDA, SCL start high 2. Master: SDA low to signal start 3. Master: Send out SCL, and 7 bit address followed by 0(~W) on SDA 4.
RS-485 (aka TIA-485-A, ANSI/TIA/EIA-485, TIA/EIA-485, EIA-485) is a standard defining the electrical characteristics of drivers and receivers for use in digital serial communications systems. Electrical signaling is balanced, and multipoint systems are supported.

USB-I2C - USB to I2C Communications Module Technical Specification. The USB-I2C module provides a complete interface between your PC and the I2C bus. The module is self powered from the USB cable and can supply up to 70mA at 5v for external circuitry from a standard 100mA USB port. The module is an I2C master only, not a slave.
RS485 and RS422 can bridge up to 1200m (4000'), again dependent on data rate, cable quality and physical layer driver/receiver characteristics (not all are created equal). To achieve such long distances and to increase noise immunity both RS422 and RS485 use differential data transmission. LIN (Local Interconnect Network)
