Hello
I try to implement an interrupt on eval board AM263 CC. The idea is if the button is pushed on the eval board , it should trigger an interrupt. I don't know why, but the interrupt for the gpio pin could not be registered in the interrupt table.
I could show you my port setup below:
static CONST( Port_PinConfigType, PORT_PBCFG) PortConfigSet_0_PinConfig[] =
{
{
.Port_PinId = 21,
.Port_PullInhibitEnable = PORT_PIN_PULL_INHIBIT_DEFAULT,
.Port_OutputOverride_Ctrl = 2,
.Port_InputOverride_Ctrl = 2,
.Port_DirectionChangeable = FALSE,
.Port_PinModeChangeable = TRUE,
.Port_PinLevelValue = PORT_PIN_LEVEL_LOW,
.Port_PinDirection = PORT_PIN_IN,
.Port_PinInitialMode = PORT_PIN_MODE_GPIOAB,
.Port_PullTypeSelect = PORT_PIN_PULLTYPE_DEFAULT,
.Port_SlewControl = PORT_PIN_SLEWCONTROL_DEFAULT,
.Port_NumPortModes = 1,
.Port_PinMode =
{ [0] =
{
.mode = PORT_PIN_MODE_GPIOAB,
.muxmode = 7, // PINA8_LIN2_TXD_GPIO_22, Dio_WriteChannel ID = 22
},
},
.Port_PinDioRegId = (1 - 1U), /* GPIO register index is 0 based */
.Port_PinDioChannelId = 21,
.Port_RegOffsetAddr = PINB8_LIN2_RXD,
.Port_PinSignalName = (const sint8 *)"GPIO_21",
.Port_PinName = (const sint8 *)"PIN_B8",
.Port_PinSetEdgeTrigger = FALSE,
.Port_PinSelectEdgeTrigger = BOTH_EDGE,
}
};
/*<PORT_PIN_CONFIGURATION>*/
static CONST( Port_DioRegConfigType, PORT_PBCFG) PortConfigSet_0_DioConfig[] =
{
[0] =
{
.Port_DioRegId = (1 - 1U), /* Dio Register is 0 based index */
.Port_BankInterruptEnable = 3,
},
[1] =
{
.Port_DioRegId = (2 - 1U), /* Dio Register is 0 based index */
.Port_BankInterruptEnable = 3,
},
[2] =
{
.Port_DioRegId = (3 - 1U), /* Dio Register is 0 based index */
.Port_BankInterruptEnable = 3,
},
[3] =
{
.Port_DioRegId = (4 - 1U), /* Dio Register is 0 based index */
.Port_BankInterruptEnable = 3,
}
};
in main this functions are called:
Port_Init(PortConfigSet_0_pt);
vimInit();
BswTest_Dio_GPIO21InterruptSetup();
////////////////end main
static void BswTest_Dio_GPIO21InterruptSetup(void)
{
VIMRegs *ptrVIMRegs;
uint32 groupIdx;
uint32 bit;
Vim_IntCfg intCfg;
intCfg.map = VIM_INTTYPE_IRQ;
intCfg.type = VIM_INTTRIGTYPE_LEVEL;
/*
* Register GPIO interrupt
* */
intCfg.intNum = 142U;//GPIO_INT_XBAR_GPIO_0_BANK_INTR_1;
intCfg.handler = BswTest_Dio_GPIO21InterruptHandler;
intCfg.priority = VIM_PRIORITY_9;
vimRegisterInterrupt(&intCfg);
}
static void BswTest_Dio_GPIO21InterruptHandler(void)
{
Dio_WriteChannel(DioConf_DioChannel_GPIOAB_Ch22, STD_HIGH);
System_printf("you pushed the button/n");
}
It is actually a copy paste from mcal library 4.3.1 . Are there some thing wrong?
When the vimRegisterInterrupt(&intCfg); is executed, the enable bit for interrupt is not set top 1 .!!!
Could you also explain what is for .Port_BankInterruptEnable is the dio config ?
Thank you in advance
