Compiler/TM4C1294NCPDT: GPTM configuration: timer in upward mode

Hello Antouriel,

I was not able to understand the first half of your post which I think has your problem statement in it. Can you please re-post that in English? Thank you.

Regarding TivaWare library, the example projects and SPMU298 are the best way to go. You can look at both the peripherals/timer folder and also some timer examples for LaunchPad in the latest TivaWare (2.2.0.295).

There's an apology, I'm sorry! I'm rewriting the first part:

"Hello! Good morning, everyone! I have some questions about how to set the timer using the TIVAWARE libraries. I already checked the examples provided by the manufacturer, now I want to know how I can make this delay configurable in an ascending way in fact this is my code:

#include <stdint.h>
#include <stdbool.h>
#include "inc/tm4c1294ncpdt.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
#include "inc/hw_memmap.h"
#include "driverlib/timer.h"
#include "driverlib/interrupt.h"

//Variables globales
bool state;

void Timer0IntHandler(void)
{
    TimerIntClear(TIMER0_BASE,TIMER_TIMA_MATCH);

    if(state==true)
    {
        GPIOPinWrite(GPIO_PORTN_BASE,GPIO_PIN_0|GPIO_PIN_1,0x03);
        state=false;
    }
    else
    {
        GPIOPinWrite(GPIO_PORTN_BASE,GPIO_PIN_0|GPIO_PIN_1,0x00);
        state=true;
    }
}

void main(void)
{
    //Habilita el modulo GPIO N
    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
    //Espera que el modulo GPIO N este listo
    while(!SysCtlPeripheralReady(SYSCTL_PERIPH_GPION));

    //Configuramos el puerto N 0 y 1 como salidas
    GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE,GPIO_PIN_0|GPIO_PIN_1);

    //Habilitamos el TIMER0
    SysCtlPeripheralEnable(SYSCTL_PERIPH_TIMER0);
    //Esperamos a que el modulo TIMER0 este listo
    while(!SysCtlPeripheralReady(SYSCTL_PERIPH_TIMER0));

    //Configura el Timer para 16 bits en modo periodico
    TimerConfigure(TIMER0_BASE,TIMER_CFG_A_PERIODIC_UP);
    //Carga el valor de Timeout
    TimerMatchSet(TIMER0_BASE,TIMER_A,65535);
    //Activa la interrupcion time out
    TimerIntEnable(TIMER0_BASE,TIMER_TIMA_MATCH);
    TimerIntRegister(TIMER0_BASE,TIMER_A,Timer0IntHandler);
    IntEnable(INT_TIMER0A);
    IntMasterEnable();
    TimerEnable(TIMER0_BASE,TIMER_A);
/*****************************************Main program*****************************************************/
    while(true);
}

I assumed that something similar to the example only that using the match register, but it doesn't work for me and another doubt is how I can use the prescaler here because at register level I can do it, but using the TIVAWARE library I don't have the slightest idea.

The teacher explained to us more or less some peripherals not all, apart from the SPMU298a manual, is there any book or page where I can help me to understand the TIVAWARE library?"
