Texas Instruments MSP430 : Architecture and Programming

Explore how the MSP430 clock system uses a unified clock architecture with master clock for CPU, sub-master clock for mid-range peripherals, and auxiliary clock for low-speed devices, enabling low-power operation.

Compare MSP430 versions by memory sizes, voltage and frequency ranges, and hardware features like a hardware multiplier and ADC for low-power instrumentation with an LCD interface.

Discover how the MSP430 general-purpose registers, including the program counter and stack pointer, manage memory, 16-bit data, and flags such as zero, carry, overflow, plus constant generator usage.

Explore a low-cost MSP430 launch pad with onboard emulator to download, run, and debug code as it executes on the microcontroller, using USB, buttons, and LCD.

Configure port direction, enable pull up or pull down resistors to avoid floating inputs, and read port data after initializing pull configuration on the MSP430.

Learn to write a simple MSP430 led flashing program: disable the watchdog timer, set P1.0 as output, and blink the led using a while(1) loop with a delay.

Explore four MSP430 timer modes: up mode, continuous mode, a continuous mode variant without capture/compare, and up/down mode. Each mode defines how the counter increments, rolls over, and generates pulses.

Learn pwm signal generation on the MSP430, using duty cycle to control on-time and off-time, and thereby regulate dc motor speed via a counter-based block diagram and compare logic.
