Tool/software: Code Composer Studio
Hello,
Please refer below code and I want to drive particular segment to blinking on LCD. For example,"ABC" so,'A' only blink 'B' 'C' stable.
LCDCBLKCTL_L |= LCDBLKPRE0 | LCDBLKPRE2 | LCDBLKMOD_2; <--This registers function blink all "ABC" LCD segments.
int main(void)
{
WDTCTL = WDTPW | WDTHOLD; // Stop WDT
PJSEL0 = BIT4 | BIT5; // For LFXT
// Initialize LCD segments 0 - 21; 26 - 43
LCDCPCTL0 = 0xFFFF;
LCDCPCTL1 = 0xFC3F;
LCDCPCTL2 = 0x0FFF;
// Disable the GPIO power-on default high-impedance mode
// to activate previously configured port settings
PM5CTL0 &= ~LOCKLPM5;
// Configure LFXT 32kHz crystal
CSCTL0_H = CSKEY >> 8; // Unlock CS registers
CSCTL4 &= ~LFXTOFF; // Enable LFXT
do
{
CSCTL5 &= ~LFXTOFFG; // Clear LFXT fault flag
SFRIFG1 &= ~OFIFG;
}while (SFRIFG1 & OFIFG); // Test oscillator fault flag
CSCTL0_H = 0; // Lock CS registers
// Initialize LCD_C
// ACLK, Divider = 1, Pre-divider = 16; 4-pin MUX
LCDCCTL0 = LCDDIV__1 | LCDPRE__16 | LCD4MUX | LCDLP;
// VLCD generated internally,
// V2-V4 generated internally, v5 to ground
// Set VLCD voltage to 2.60v
// Enable charge pump and select internal reference for it
LCDCVCTL = VLCD_1 | VLCDREF_0 | LCDCPEN;
LCDCCPCTL = LCDCPCLKSYNC; // Clock synchronization enabled
LCDCMEMCTL = LCDCLRM; // Clear LCD memory
// HERE Alpha and digital segment function call
LCDMEM[pos1] = alphabetBig['U'-65][0]; //U
LCDMEM[pos2] = alphabetBig['S'-65][0]; //S
// //LCDMEM[pos3]=0x3F; // b
// LCDM14 = 0x01;
showChar('B',pos3);
//LCDM5=0x01;
LCDCBLKCTL_L |= LCDBLKPRE0 | LCDBLKPRE2 | LCDBLKMOD_2; //Blinking LCD for ALL segment
showChar('B',pos4);
//Turn LCD on
LCDCCTL0 |= LCDON;
__bis_SR_register(LPM3_bits | GIE);
__no_operation();
//
// return 0;
}
Please provide me little solution for drive particular segment blinking.
