Hi all,
I am working on a project that has MSP430G2333 .In normal cases the controller an the code runs fine but when I am testing multiple times and varying the Vcc from 1.2V-3.3V the controller sometimes hangs and does not respond as required. Firstly I thought there is problem in my code and checked the code thoroughly but can not find and potential reason for the hanging.
Then I wrote a simple program that turn on a LED attached to its GPIO pin when ever the MCU boots.(No peripherals like ADC,UART is enabled )
I am attaching the code here;
void main() { WDTCTL = WDTPW + WDTHOLD; __enable_interrupt(); BCSCTL1 = 0x0F; // Set range DCOCTL = 0x70; // Set DCO step + modulation BCSCTL3 = 0x34; //16MHZ _disable_interrupt(); P1DIR|=BIT7; P1OUT|=BIT7; while(1); }
the mention code run normally but the controller hangs sometime and does not response.
