TC397:点灯&GPIO常规操作

只看该作者 · 2023-10-27 10:54

如下为GPIO的简单是引脚操作函数：

设置引脚MODE：

void IfxPort_setPinModeInput(Ifx_P *port, uint8 pinIndex, IfxPort_InputMode mode);

void IfxPort_setPinModeOutput(Ifx_P *port, uint8 pinIndex, IfxPort_InputMode mode);

IfxPort_setPinModeInput(&MODULE_P33, 0, IfxPort_InputMode_pullUp);

IfxPort_setPinModeOutput(&MODULE_P33, 0, IfxPort_OutputMode_pushPull, IfxPort_OutputIdx_general);

设置引脚电平：

void IfxPort_setPinHigh(Ifx_P *port, uint8 pinIndex);

void IfxPort_setPinLow(Ifx_P *port, uint8 pinIndex);

IfxPort_setPinLow(&MODULE_P33, 0);

设置引脚状态：

void IfxPort_setPinState(Ifx_P *port, uint8 pinIndex, IfxPort_State action)

设置引脚翻转：

void IfxPort_togglePin(Ifx_P *port, uint8 pinIndex);

读取引脚状态：

boolean IfxPort_getPinState(Ifx_P *port, uint8 pinIndex)

API详细参见：IfxPort.h

延时函数：

waitTime(IfxStm_getTicksFromMilliseconds(BSP_DEFAULT_TIMER, WAIT_TIME)); /* Wait 500 milliseconds

如下点灯：

Blinky LED文件：

#include "IfxPort.h"
#include "Bsp.h"

#define LED_D107 &MODULE_P13,0                                        /* LED D107: Port, Pin definition    */
#define WAIT_TIME 500                                                    /* Wait time constant in milliseconds */

/* This function initializes the port pin which drives the LED */
void initLED(void)
{
IfxPort_setPinModeOutput(LED_D107, IfxPort_OutputMode_pushPull, IfxPort_OutputIdx_general);

IfxPort_setPinHigh(LED_D107);
}

void blinkLED(void)
{
IfxPort_togglePin(LED_D107);                                              /* Toggle the state of the LED    */
waitTime(IfxStm_getTicksFromMilliseconds(BSP_DEFAULT_TIMER, WAIT_TIME)); /* Wait 500 milliseconds          */
}

main.c

#include "Ifx_Types.h"
#include "IfxCpu.h"
#include "IfxScuWdt.h"
#include "Blinky_LED.h"

IFX_ALIGN(4) IfxCpu_syncEvent g_cpuSyncEvent = 0;

void core0_main(void)
{
IfxCpu_enableInterrupts();

/* !!WATCHDOG0 AND SAFETY WATCHDOG ARE DISABLED HERE!!
   * Enable the watchdogs and service them periodically if it is required
   */
IfxScuWdt_disableCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword());
IfxScuWdt_disableSafetyWatchdog(IfxScuWdt_getSafetyWatchdogPassword());

/* Wait for CPU sync event */
IfxCpu_emitEvent(&g_cpuSyncEvent);
IfxCpu_waitEvent(&g_cpuSyncEvent, 1);

initLED();  /* Initialize the LED port pin    */

while(1)
{
      blinkLED(); /* Make the LED blink          */
}
}
