(a) List two (2) features of real time operating system (RTOS). (2 marks) (b) Give an example for comparing the terminology of job and task. (c) (4 marks) Two type of input and output (I/O) expander chips can be selected for extending our input/output peripheral which are MCP23017 and MCP23S17. The MCP23017 uses inter-integrated circuit (IC) interface while MCP23S17 uses serial peripheral interface (SPI) interface. (i) Select one (1) of the suitable chip either MCP23017 or MCP23S17 for extending the I/O of Arduino system. Give a concrete justification on your selection. (ii) (iii) (2 marks) Based on selection in (c)(i), sketch a schematic diagram between I/O expander chip to Arduino controller. (4 marks) To verify the good communication interface, we need to capture and analyze the waveform of data transmition. Analyze the common data transmission protocol for write mode operation of your interface selection in (c)(i). Acti marks) Go to (a) List two (2) features of real time operating system (RTOS).
