Aurix-TC275單片機(jī)與TLE7368-3E

使用心得分享

說明：TLE7368有觸發(fā)啟動(dòng)和低電平關(guān)機(jī)進(jìn)入低功耗功能，上電時(shí)候讓四個(gè)LED依次點(diǎn)亮，程序運(yùn)行10s中后，將P10.8置低則TLE7368電源關(guān)閉，系統(tǒng)進(jìn)入低功耗運(yùn)行，LED燈不再閃爍，重新啟動(dòng)需要再次按啟動(dòng)按鍵。

實(shí)現(xiàn)代碼：void GPIO_Test(void)

{

IfxPort_togglePin(&MODULE_P33, 8);

IfxStm_waitTicks(&MODULE_STM0, 4000000);

IfxPort_togglePin(&MODULE_P33, 9);

IfxStm_waitTicks(&MODULE_STM0, 4000000);

IfxPort_togglePin(&MODULE_P33, 10);

IfxStm_waitTicks(&MODULE_STM0, 4000000);

IfxPort_togglePin(&MODULE_P33, 11);

IfxStm_waitTicks(&MODULE_STM0, 4000000);

TM_i++;

if(TM_i>=62)//約10S鐘后關(guān)機(jī)進(jìn)入低功耗

{

IfxPort_setPinMode(&MODULE_P10, 8, IfxPort_Mode_outputPushPullGeneral);

IfxPort_setPinLow(&MODULE_P10, 8);//P10.8置低，關(guān)閉電源進(jìn)入低功耗

}

}
