Hi all,
In my application I need to send some data from the MSP430FR5969 to the PC via UART. For that purpose, I've written the following code:
#include <msp430fr5969.h>
float ToF_buffer[]={1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 1.10};
float *p=*(&ToF_buffer);
void initialize_Serial();
void serial_send(char);
void setup() {
PM5CTL0 &= ~LOCKLPM5;
P1DIR &= ~0x02;
P1REN |= 0x02;
P1IES |= 0x02;
P1IFG &= ~0x02;
P1IE |= 0x02;
// Output SMCLK in P3.4
P3DIR |= 0x10;
P3SEL1 |= 0x10;
initialize_Serial();
}
void loop(){
nop;
}
#pragma vector=PORT1_VECTOR
__interrupt void PORT1_ISR_HOOK(void){
char ToF_data = '1';
serial_send(ToF_data);
P1IFG &= ~0x02;
P1IE |= 0x02;
}
void serial_send (char TX_data){
while(!(UCA0IFG & UCTXIFG));
P4OUT ^= 0x40;
UCA0TXBUF = TX_data;
while (!(UCA0IFG & UCTXCPTIFG));
UCA0IFG &= ~UCTXCPTIFG;
}
void initialize_Serial(){
P2SEL1 |= 0b00000011;
P2SEL0 &= ~0b00000011;
UCA0CTL1 |= UCSSEL_2 | UCSWRST;
UCA0BR0 = 0x08;
UCA0BR1 = 0x00;
UCA0MCTLW = 0x1111011100000001;
UCA0CTL1 &= ~UCSWRST;
}
The idea is to use the UART without interrupt. Instead, whenever the button P1.1 is pressed, I want a message to be sent via UART to be written on the serial monitor. The baudrate is 115200 for a 16MHz SMCLK.
However, when trying to send the char '1', I can only read a ' in the serial monitor (set to the right baudrate).
Posterior to this, instead of sending a single character, I want to send a float via this interface, for which I need help.
Thanks in advance,
Joaquim
