Hi, guys, I cannot seem to be able to stop the watchdog on the Energia + MSP432 combo. (MSP-EXP432P401R Rev 1.0 + Energia 0101E0016 on Win7-64bit) // My minimal code buzzes the red led at 2MHz: #include "msp432p401r.h" void setup() { WDTCTL = WDTPW | WDTHOLD; // Stop WDT pinMode(RED_LED, OUTPUT); // configure pin } void loop() { while (1) { P2OUT ^= 0x01; P2OUT ^= 0x01; // flip pin twice }; } The 2MHz output signal freezes for 12us in either "1" or "0" state every 1ms. WDTHOLD bit does not help (in fact, any WDTCTL actions seem to be ignored). Cross testing done: - TI CCS Cloud correctly builds C code for same MSP-EXP432 board (i.e. WDTCTL line does make a difference there) - Same Energia IDE correctly builds equivalent code for a MSP-EXP430G2 /2452 board (WDTCTL line again does make a difference). (In addition, if it matters: pure C compiling in Energia as per https://bennthomsen.wordpress.com/engineering-toolbox/ti-msp430-launchpad/using-energia-to-code-in-c/ does not work for the 432 (compiles and flashes OK, but board remains dead) while it does work for a plain ol' 430 board.) There, hope there's enough data. Any ideas? Thanks a lot! Matjaz

Hello, I am new to the MSP430 Launchpad and am trying to get familiar with CCS5 and the MS430. I am trying to use macros to control the watch dog timer but I can't seem to get it working. The code builds fine but when it gets run it gets hung up and won't give me any kind of error until I pause. The error is as follows: Can't find a source file at "/tmp/TI_MKLIBTw7SkT/SRC/autoinit.c" Though, I am able to get it working if I set all the bits at once. See below for examples. This does not work.... #define wdt_password_set() ( WDTCTL |= WDTPW ) #define wdt_mode_interval() ( WDTCTL |= WDTTMSEL) #define wdt_clear() ( WDTCTL |= WDTCNTCL ) #define wdt_source_aclk() ( WDTCTL |= WDTSSEL ) #define wdt_divider_8192() ( WDTCTL |= WDTIS1 ) wdt_password_set(); wdt_mode_interval(); wdt_clear(); wdt_source_aclk(); wdt_divider_8192(); But, this line of code works perfectly... WDTCTL = WDTPW | WDTTMSEL | WDTCNTCL | WDTSSEL | WDTIS1; Is there something that I am missing completely? Thanks in advance. Everett
