ButtonsPoll()

Hello Vikas,

The prototype can be found in drivers for every board examples. There is no tutorial document as such.

C:\ti\TivaWare_C_Series-2.1.0.12573\examples\boards\ek-tm4c123gxl-boostxl-senshub\drivers

Hi I what you said but an error is still running

"C:/ti/TivaWare_C_Series-2.1.0.12573/examples/boards/ek-tm4c123gxl/drivers/buttons.c", line 35: fatal error #1965: cannot open source file "drivers/buttons.h"
1 catastrophic error detected in the compilation of "C:/ti/TivaWare_C_Series-2.1.0.12573/examples/boards/ek-tm4c123gxl/drivers/buttons.c".
Compilation terminated.
gmake: *** [buttons.obj] Error 1

I hope you could help me

Hello Luis

Is the include file path mapped in the compilation flow? Please check the compile log for include path

Amit

could you give me your e-mail, i want to show you some images, i really need to continue learning how to use my tiva

Hello Luis

You can post it on the forum

hello i could erase the other error but now i have other hope you could help me this is the code

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
#include "examples\boards\ek-tm4c123gxl\drivers\buttons.h"

int PinData=2;
unsigned char ucDelta = 0;
unsigned char ua = 0;
unsigned char ucState =0;

int main(void)
{
SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_XTAL_16MHZ|SYSCTL_OSC_MAIN);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3);
while(1)
{
ucState = ButtonsPoll(&ucDelta, &ua);
if (BUTTON_PRESSED(LEFT_BUTTON, ucState, ucDelta))
{
GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, PinData);
SysCtlDelay(40000000);
GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, 0x00);
SysCtlDelay(40000000);
//if(PinData==8) {PinData=2;} else {PinData=PinData*2;}
}
else {GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, 0x0E);}
}
}

and these are the erros

error #10234-D: unresolved symbols remain
error #10010: errors encountered during linking; "lab3.out" not built

Hello Luis,

It seems that the driverlib.lib has not been included during link time.
