I made a shell of my project with the workaround from the included link. I adjusted some stuff for a simpler implementation. In the noted link, he adds a mask to clear all the interrupts. In my case, I wanted to leave the interrupts separate. I also use the prebuilt interrupts instead of building my own. An addition from my original project is adding a 4-button DPAD with a separate enter button. I want the DPAD to navigate and the enter to activate a specified function, so I want their interrupts to be cleared separately. In conjunction, the CAN channels are separate, so I only want to send a message on the active network.
Below, I took snippets from my code and boldened the important parts. As well a screenshot of the TopDesign for those not wanting to download the entire project.
int main(void)
{
CyGlobalIntEnable; /* Enable global interrupts. */
/*Interrupt Start*/
Glb_isr_Start();
DPAD_isr_Start();
/*Set Interrupt for Non-Contiguous*/
dpad_SetInterruptMode(dpad_ent_0_INTR, dpad_ent_INTR_RISING);
RX_1_SetInterruptMode(RX_SW_0_INTR,RX_SW_INTR_FALLING);
for(;;)
{
}
}
/* `#START DPAD_isr_Interrupt` */
if(dpad_ClearInterrupt())
{
RX_isr_Start();
}
if(dpad_ent_ClearInterrupt())
{
led1_Write(~led1_Read());
}
/* `#START RX_isr_Interrupt` */
if(RX_1_ClearInterrupt())
{
// CAN_1_SendMsg();
}
if(RX_SW_ClearInterrupt())
{
// CAN_SW_SendMsg();
}
CyDelay(1);
led2_Write(~led2_Read());
RX_isr_Stop();
