Most developers begin with TI Code Composer Studio (Eclipse-based) or Keil uVision. However, a popular and simple way to start is with Energia (an Arduino-like IDE).
Example: Blinking an LED (Energia/Arduino style)
// Pin mapping: On MSP432 LaunchPad, LED1 is at P1.0 void setup() pinMode(P1_0, OUTPUT); // RED LED
void loop() digitalWrite(P1_0, HIGH); delay(500); digitalWrite(P1_0, LOW); delay(500);
Example: Bare-metal register-level programming (CCS)
#include "msp432p401r.h"
void main(void) WDT_A->CTL = WDT_A_CTL_PW
The defining feature of the MSP432 is its Low-Power (LP) architecture. In embedded systems, the CPU is often idle, waiting for an event (like a button press).
The MSP432 utilizes EnergyTrace++ technology and distinct Low-Power Modes (LPM):
By spending 99% of its time in LPM and waking up only to process data, a device running on a coin cell battery can last for years.
