Download Viewīuilding an embedded system from an idea to a product is a slow and expensive process requiring a lot of expertise. Furthermore, the algorithm is computationally cheap, and its average overhead is very competitive with that of existing algorithms. It guarantees in the worst case to add no more than one byte in 254 to any packet. This paper presents a new byte stuffing algorithm, called Consistent Overhead Byte Stuffing (COBS), that tightly bounds the worst case overhead. To adhere to this regulation, the practice is to set the maximum packet size artificially low so that no packet, even after worst case overhead, can exceed the transmission time limit. For example, the transmission time for ISM-band packet radio transmitters is strictly limited by FCC regulation. Some increasingly popular network devices, however, care more about the worst case.
To date, byte stuffing algorithms, such as those used by SLIP, PPP and AX.25, have been designed to incur low average overhead but have made little effort to minimize worst case overhead. The extra length is referred to in this paper as the overhead of the algorithm. Download Viewīyte stuffing is a process that transforms a sequence of data bytes that may contain ‘illegal’ or ‘reserved’ values into a potentially longer sequence that contains no occurrences of those values. The simplicity and flexibility of this approach makes it attractive to consider as an alternative to other control systems such as RS-485 or CAN bus. As an example, a system is described for control of LED lighting displays and it is suggested that the power for the LEDs, and the I2C control system, might be economically provided using ‘extra low voltage’ distribution at 48 V using either the control signal cable or similar low cost wiring in a manner similar to that used in ‘Power over the Ethernet’ systems.

Each drop point or node can be individually selected for bidirectional data communication with the Master just by using normal I2C software addressing. Conventional twisted pair communication cabling with its convenient connectors, and a ‘modular’ I2C system approach, make large system assembly easy. That ‘regeneration’ of clean I2C signals enables building long I2C buses by combining together relatively short bus sections, each say less than 20 meters, using such buffers or multiplexers that contain them. The availability of powerful I2C buffers that drive their I/Os on both sides to a nominal ground or ‘zero offset’ logic level allows the removal of noise introduced into one section of a larger bus system.
