Open Ended Problem
1. Interface a pressure sensor giving full scale range output as 10 mV for 300 mmHg with MSP430.Design appropriate signal conditioning circuit and write a ‘c’ program to monitor the pressure in mmHg.
2. A load cell is required to be interface with MSP430 which gives 2mV as its full scale output. Design appropriate signal conditioning circuit and write a ‘c’ program to acquire the weight data and display this data on 3 and ½ multiplexed display field.
3. Use timer to generate a Pulse Width Modulated wave whose duty cycle is varied such that the average voltage is equal to the analog signal in the range of 0 to 2.5 Volts. Write a ‘c’ program for this task.
4. Use hardware multiplier to calculate RMS value of current and power associated with sinusoidal analog signal given as input to MSP430.
5. With the help of DMA controller implement digital FIR filter and use this filter for implementing Low Pass Filter action for the analog signal given as input to MSP430.
6. Implement suitable RTOS on suitable MCU platform to explore RTOS fundamentals.
