Green 7-segment LED modules

[zeke 693]

Now I remember where I saw that LCD module!

 

I used to repair cell phones for a living many years ago.

 

That LCD was in the handset for a cell phone that was made in the UK. I wished that I could remember the manufacturer name.

 

I'll see if I can find more info on it.

Hey guys, I found another 7-digit module like the one above. One difference though, this one is ORANGE!

 

And here is a simple program I used to test it:

#include "MSP430G2252.h"

#define NUM0 0x3F
#define NUM1 0x06
#define NUM2 0x5B
#define NUM3 0x4F
#define NUM4 0x66
#define NUM5 0x6D
#define NUM6 0x7D
#define NUM7 0x07
#define NUM8 0x7F
#define NUM9 0x6F

int NUMBER=0;

char DIGI[7] = {NUM0,NUM1,NUM2,NUM3,NUM4,NUM5,NUM6};
const char BIT[8] = {0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};

int DIGIT=0;
int c = 0;
void main( void ){
// Stop watchdog timer to prevent time out reset
WDTCTL = WDTPW + WDTHOLD;
BCSCTL1 = CALBC1_1MHZ;
DCOCTL = CALDCO_1MHZ;

 	P1OUT = 0x7F;
P1DIR = 0x7F;
   P2SEL = 0x00;   	// allow 2.6-2.7 to output
P2OUT = 0x7F;
P2DIR = 0x7F;
P1IES = BIT7;
   P1IFG = 0;
   P1IE = BIT7;
P2IES = BIT7;
   P2IFG = 0;
   P2IE = BIT7;
__enable_interrupt();

for(;{
	P2OUT = ~BIT[c];
 		P1OUT = DIGI[c];
	__delay_cycles(50);
 		P1OUT = 0x00;
	c++;
	if(c == 7) c = 0;
}
}

#pragma vector=PORT1_VECTOR
__interrupt void PORT1_ISR(void)
{
NUMBER++;
if(NUMBER == 10)
	NUMBER = 0;
switch (NUMBER){
case 0:
	DIGI[DIGIT] = NUM0;
	break;
case 1:
	DIGI[DIGIT] = NUM1;
	break;
case 2:
	DIGI[DIGIT] = NUM2;
	break;
case 3:
	DIGI[DIGIT] = NUM3;
	break;
case 4:
	DIGI[DIGIT] = NUM4;
	break;
case 5:
	DIGI[DIGIT] = NUM5;
	break;
case 6:
	DIGI[DIGIT] = NUM6;
	break;
case 7:
	DIGI[DIGIT] = NUM7;
	break;
case 8:
	DIGI[DIGIT] = NUM8;
	break;
case 9:
	DIGI[DIGIT] = NUM9;
	break;
}
P1IFG &= ~BIT7;
}

#pragma vector=PORT2_VECTOR
__interrupt void PORT2_ISR(void)
{
DIGIT++;
if(DIGIT == 7)
	DIGIT = 0;
P2IFG &= ~BIT7;
}
