Re: numéro 5

Pour résumer :

SW-EK-TM4C1294XL Open Silicium :

#include <stdint.h>
#include <stdbool.h>
#include "inc/hw_memmap.h"
#include "driverlib/gpio.h"
#include "driverlib/rom.h"
#include "driverlib/rom_map.h"
#include "driverlib/sysctl.h"
int main(void) {
 uint32_t g_ui32SysClock;
 // Fonctionnement sur PLL à 120 MHz.
 g_ui32SysClock = MAP_SysCtlClockFreqSet((
 SYSCTL_XTAL_25MHZ | // fréquence de l'oscillateur
 SYSCTL_OSC_MAIN | // oscillateur externe (quartz)
 SYSCTL_USE_PLL | // sortie PLL comme sysclock
 SYSCTL_CFG_VCO_480), // PLL VCO output á 480-MHz
 120000000); // freq demandée
 // Activation du module GPIO port N
 MAP_SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
 // Configuration de PN1 en sortie
 MAP_GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, GPIO_PIN_1);
 while(1) {
 // Active la led
 MAP_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, GPIO_PIN_1);
 // délai 
 MAP_SysCtlDelay(g_ui32SysClock /3);
 // Désactive la led
 MAP_GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, 0);
 // délai
 MAP_SysCtlDelay(g_ui32SysClock /3);
 }
}

SW-EK-TM4C1294XL Hackable :

int led = 13;
void setup() { 
 // initialize the digital pin as an output.
 pinMode(led, OUTPUT); 
}
void loop() {
 digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
 delay(1000); // wait for a second
 digitalWrite(led, LOW);
 delay(1000);
}
