Other Parts Discussed in Thread: MSP430G2553
Hi! I need urgent help with a code i'm working on, to send info via UART connection to a serial module attached to a 16x2 LCD. The thing is that i've made a very simple code but i'm new in microcontrollers programming; i'm using the launchpad and i'v read a lot about this but the LCD screen doesn't respond.
I think my problem is on the serial communication implementation; i'm not really good at this microcontroller stuff yet
My code:
#include <msp430g2553.h>
volatile unsigned char TXByte; // Value sent over UART when Transmit() is called
void Transmit(void);
int main(void) {
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
BCSCTL1 = CALBC1_1MHZ; // Set range
DCOCTL = CALDCO_1MHZ; // SMCLK = DCO = 1MHz
P1DIR |= BIT2; // P1.2 Output
P1SEL |= BIT2; // P1.2 Options select
UCA0CTL0 |= UCMODE_0;
UCA0CTL1 |= UCSSEL_2;
UCA0BR0 = 104;
UCA0BR1 = 0;
UCA0MCTL = UCBRS_0;
//UCSYNC = 0; // Asíncrono
//UCMODEx = 00; // Modo UART
TXByte = 0x0C;
Transmit();
return 0;
}
//Transmits the value currently in TXByte. The function waits till it is finished transmitting before it returns.
void Transmit()
{
//while (!(IFG2 & UCA0TXIFG));
TXByte |= 0x100; // Add stop bit to TXByte
TXByte = TXByte << 1; // Add Start bit to TXByte
UCA0TXBUF = TXByte;
}
