UARTprintf

I would suggest using the search capability at the top of the page to search this forum for more information on UARTprintf. There are large number of threads on this topic.

For your case, the most likely to provide some help would be this post:
e2e.ti.com/.../312134

Some additional threads that might be helpful are:
e2e.ti.com/.../245433
e2e.ti.com/.../1504931
e2e.ti.com/.../337933
e2e.ti.com/.../337351
e2e.ti.com/.../1238303

You may want to have a look at threads about UART2 as well:
e2e.ti.com/.../427937
e2e.ti.com/.../324320

Please have a look at these threads and let me know if you need any additional help.

Hi chuck;

I took a look these questions before. I can use UARTprintf and UART2 separately but not together. I 'm pasting code here . The code does not get in to the while loop and only send 'T' one time.

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/gpio.h"
#include "drivers/pinout.h"
#include "driverlib/pin_map.h"
#include "driverlib/rom.h"
#include "driverlib/rom_map.h"
#include "driverlib/sysctl.h"
#include "driverlib/uart.h"
#include "utils/uartstdio.h"

uint32_t g_ui32SysClock;

void
ConfigureUART(void)
{
SysCtlPeripheralEnable(SYSCTL_PERIPH_UART2);
SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);
UARTIntClear(UART2_BASE,UART_INT_RX | UART_INT_RT );
GPIOPinConfigure(GPIO_PA6_U2RX);
GPIOPinConfigure(GPIO_PA7_U2TX);

GPIOPinTypeUART(GPIO_PORTA_BASE, GPIO_PIN_6 | GPIO_PIN_7);

UARTConfigSetExpClk(UART2_BASE, g_ui32SysClock, 115200,(UART_CONFIG_WLEN_8 |UART_CONFIG_STOP_ONE | UART_CONFIG_PAR_NONE));
}
int
main(void)
{
g_ui32SysClock = MAP_SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |
SYSCTL_OSC_MAIN | SYSCTL_USE_PLL |
SYSCTL_CFG_VCO_480), 120000000);
PinoutSet(false, false);

ConfigureUART();

UARTCharPut(UART2_BASE, 'T');
UARTprintf("Hello, world!\n");

while(1)
{
SysCtlDelay(g_ui32SysClock / 10 / 3);
UARTCharPut(UART2_BASE, 'T');
UARTprintf("Hello, world!\n");
SysCtlDelay(g_ui32SysClock / 10 / 3);
}
}

Hello user3667254,

Have you made any changes to the uartstdio.c file in your project. If yes then can you please share the same?

Regards
Amit

Hello user3667254,

Please call the function UARTStdioConfig with first parameter as 2 instead of calling UARTConfigSetExpClk

Do make sure that the UART2 IO's for TX and RX are configured.
