Did I fry my LP in some strange way?

My IAR KS says it can't read or write to any of my six msp's. It does identify them, so it has partial communication.

And CCS says it can't get the msp to run the code in a debug session. Any ideas?

The only thing that I had screwed up on recently was connecting +5v to P1.0, while a micro was plugged in. The led jumper was off too.

reboot? selected the right hardware in options? already tried to use another usb-port?

Hmm.. short the rx an tx jumpe(debugger side) and see if you get a double echo. This will test the UART though.

why double echo? this is just a loopback-connector - and you should get exactly the data same like what you send then

That's what I meant . Wording was a little incorrect.

Yes. Thanks, though.

Shorting the rx/tx freezes up IAR. Shorting RST/TEST gives the error "Cannot find device (or device not supported)", and shorting either pair for CCS gives the same error.

Just buy another one or I can send you one if you want.

hmmm ... shortcut them on emulator-side ... connect with terminal to your comport - 9600 N 1 - and send something - then it should return the same data - i often have problems when using RX/TX with the emulator and flashing my

Thanks for the offer blue, but I've come across something that leads me to believe that this is not a physical/burned out problem, but a software problem.

 

This is the code I've been trying to download;

#include "msp430g2252.h"

#define RD BIT7
#define WR BIT6
#define CK BIT2
#define EN BIT1
#define DIR BIT0

#define hello_world "Malfunction!*Need Input!"

void init_disp(void);
void wrLCD(char data, bool rs);
void sendStr(char string[]);
void setAddr(char addr);
bool line = 0;

void main(void){
// Stop watchdog timer to prevent time out reset
WDTCTL = WDTPW + WDTHOLD;

P1OUT = 0xFF;
P1DIR = 0xFF;
P2OUT = 0xFF;
P2DIR = 0xFF;

init_disp();
//	sendStr(hello_world);

}

void wrLCD(char data, bool rs){
P2OUT &= ~EN;
rs ? (setAddr(0x80)) : (setAddr(0x00));
P1OUT = data;
P2OUT &= ~WR;
P2OUT |= WR;
}

void init_disp(void){
setAddr(0x00);
P2OUT &= ~EN;
for(int t=0; t<2; t++){
	P1OUT = 0x38;
	P2OUT &= ~WR;
	P2OUT |= WR;
	P1OUT = 0x0E;
	P2OUT &= ~WR;
	P2OUT |= WR;
	P1OUT = 0x01;
	P2OUT &= ~WR;
	P2OUT |= WR;
	__delay_cycles(2000);
	P1OUT = 0x06;
	P2OUT &= ~WR;
	P2OUT |= WR;
	__delay_cycles(200000);
}
}

void sendStr(char string[]) {
wrLCD(0x80, 0);
line=0;
for(int str=0; (str < 32) && string[str]; str++){
	if(!line && ((string[str] == '*') || (str == 16))){ //
		wrLCD(0xC0, 0);
		line=1;
		str++;
	}
	wrLCD(string[str], 1);
}
}

void setAddr(char addr){
P1OUT = addr;
P2OUT &= ~CK;
P2OUT |= CK;
}

 

 

And this simple LED blinky program works, while the first one produces the wacky errors:

#include "MSP430G2252.h"

void main( void )
{
 // Stop watchdog timer to prevent time out reset
 WDTCTL = WDTPW + WDTHOLD;

 	P1OUT = 0xFF;
P1DIR = 0xFF;
P2OUT = 0xFF;
P2DIR = 0xFF;


for(;{
	__delay_cycles(1000000);
	P1OUT ^= 0xFF;
	P1OUT ^= 0x01;		
}
}

Yesterday morning, while searching for some escapee horses, I found a $5 bill on our non-frequented county road.

This evening, I was able to buy another launchpad. (Free shipping!)

 

Thanks for all the help! :thumbup: :wave:
