EVM430-FR6043: Unable to get Tx data in Hyper Terminal

Hello Sir,

Thanks for your response. I'm not find application port after i connected to the evm430-fr6043 board. Instead of that it showing "MCU COMM HID to serial bridge" and "MSP Tools Drivers" in Other devices of Device manager as shown in screen shot. 

Thanks,

Ashok.

Hello Sir,

where can i download drivers to find the uart application port?

I connected RXD and TXD in J3.

Thanks,

Ashok.

Hello sir,

This is code i used with minor changes i.e. data=1.

#include <msp430.h>
#include "msp430fr6043.h"
#include "stdint.h"

uint8_t data=1;

int main(void)
{
WDTCTL = WDTPW | WDTHOLD; // Stop Watchdog

// Configure GPIO
P1SEL0 |= (BIT2 | BIT3);
P1SEL1 &= ~(BIT2 | BIT3); // USCI_A1 UART operation

// Disable the GPIO power-on default high-impedance mode to activate
// previously configured port settings
PM5CTL0 &= ~LOCKLPM5;

// Startup clock system with max DCO setting ~8MHz
CSCTL0_H = CSKEY_H; // Unlock CS registers
CSCTL1 = DCOFSEL_3 | DCORSEL; // Set DCO to 8MHz
CSCTL2 = SELA__VLOCLK | SELS__DCOCLK | SELM__DCOCLK;
CSCTL3 = DIVA__1 | DIVS__1 | DIVM__1; // Set all dividers
CSCTL0_H = 0; // Lock CS registers

// Configure USCI_A3 for UART mode
UCA1CTLW0 = UCSWRST; // Put eUSCI in reset
UCA1CTLW0 |= UCSSEL__SMCLK; // CLK = SMCLK
// Baud Rate calculation
// 8000000/(16*9600) = 52.083
// Fractional portion = 0.083
// User's Guide Table 24-4: UCBRSx = 0x04
// UCBRFx = int ( (52.083-52)*16) = 1
UCA1BRW = 52; // 8000000/16/9600
UCA1MCTLW |= UCOS16 | UCBRF_1 | 0x4900;
UCA1CTLW0 &= ~UCSWRST; // Initialize eUSCI
UCA1IE |= UCRXIE; // Enable USCI_A3 RX interrupt

while(!(UCA1IFG & UCTXIFG));
UCA1TXBUF = data;

__bis_SR_register(LPM3_bits + GIE); // Enter LPM3, interrupts enabled
__no_operation(); // For debugger

Hi, 

Do you already install the driver normally? you can fine the link in EVM430-FR6043 user guide.

This code should can trans the data that received, any problem?

Best Regards

Johnson

Hello sir,

I installed drivers

I installed drivers. But after connecting my usb cable to pc I can't see the communication ports.

Code is fine. But when running code i'm getting the junk data in hyper terminal.

Thanks,

Ashok.

Hi,

Does the baud are match with seeting?

The seeting in this code is 9600.

Best Regards

Johnson

Hello sir,

The seeting in this code is 9600.

Baud rate is set as 9600 which is similar to code.

Thanks,

Ashok.

Hi Ashok,

Do you have logiic analysis, if yes, maybe can capture the wave and try to find something.

I will test this code in my side and go back.

Thanks!

Best Regards

Johnson

Hello Sir,

I don't have logic analyzer but i have oscilloscope. So i check at txd pin but it not captures exact data. I don't know whether it is problem of oscilloscope or Txd pin. 

Thanks,

Ashok.

Hi Ashok,

Got it, I will test in my side and provide a code can run normal later.

Thanks!

Best Regards

Johnson

Hello sir,

Thank you for your suggestion. I tried this example code and got desired data at the hyper terminal. I tried with same data echo uart example using drivers library then i'm got nothing in the hyper terminal and also check whether the both are running with same speed (i.e. 9600).

#include "driverlib.h"

uint16_t i;
uint8_t RXData = 0, TXData = 'A';
uint8_t check = 0;

void main(void)

    // stop watchdog
    WDT_A_hold(WDT_A_BASE);



    //Set DCO frequency to 8 MHz
    CS_setDCOFreq(CS_DCORSEL_0,CS_DCOFSEL_3);

    CS_initClockSignal(CS_ACLK,CS_VLOCLK_SELECT,CS_CLOCK_DIVIDER_1);

    //Set SMCLK = DCO with frequency divider of 1
    CS_initClockSignal(CS_SMCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);

    //Set MCLK = DCO with frequency divider of 1
    CS_initClockSignal(CS_MCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);
