48. use data corruption What is 1 C IPC is a multi master serial single ended bus that is used to attach low speed peripherals to computer or embedded systems 1 C uses only two open drain lines Serial Data Line SDA and Serial Clock SCL pulled up with resistors SCL line is driven by a master while SDA is used as a bidirectional line either by a master or slave device Up to 112 slave devices can be connected to the Same bus Each slave must have a unique address Digital signals have two discrete states which are decoded as high and low and interpreted as logic 1 and logic 0 Analog signals on the other hand are continuous and can have any value within defined range A D converters are Specialized circuits which can convert analog signals voltages into a digital representation usually in form of an integer number The value of this number is linearly dependent on the input voltage value Most microcontrollers nowadays internally have A D converters connected to one or more input pins Some of the most important parameters of A D converters are conversion time and resolution Conversion time determines how fast can an analog voltage be represented in form of a digital number This is an important parameter if you need fast data acquisition The other parameter is resolution Resolution represents the number of discrete steps that supported voltage range can be divided into It determines the sensitivity of the A D converter Resolutio
