Hi @underdangerous
Based on your description, it seems like you have done the necessary steps to set up the LINFlexD module and the interrupt vector table. However, there are a few things you might want to check:
- Ensure that the interrupt controller is properly configured and enabled. The interrupt controller is responsible for managing the interrupts and dispatching them to the correct handlers.
- Check if the LINFlexD module is properly initialized. This includes setting up the LINFlexD module for the correct mode (in your case, slave mode), setting up the baud rate, enabling the necessary interrupts, and so on.
- Verify that the interrupt handler function is correctly defined and registered in the interrupt vector table. The function name in the interrupt vector table should match exactly with the function definition in your code.
Here is a code snippet that shows how to set up the LINFlexD module and the interrupt vector table:
// Initialize LINFlexD module void LINFlexD_Init(void) { // Set LINFlexD module to slave mode LINFlexD->LINCR1 = 0x00000001;
// Set baud rate LINFlexD->LINIBRR = 0x0000000F; LINFlexD->LINFBRR = 0x0000000F;
// Enable RXI interrupt LINFlexD->LINIER = 0x00000004; }
// Define RXI interrupt handler void LINFlexD_RXI_Handler(void) { // Handle RXI interrupt }
// Register RXI interrupt handler in interrupt vector table void Interrupt_Vector_Table_Init(void) { // Register LINFlexD_RXI_Handler in interrupt vector table Interrupt_Vector_Table[LINFlexD_RXI_IRQn] = LINFlexD_RXI_Handler; }
