Hi TI Team,
We interfacing a 4x4 keypad with TMDSEVM6678LE, We want to do interrupt-based keypress scanning. That's why, We follow the CLS API, In this code We want to generate the interrupt while columns are being pressed (as per this C0, C1, C2, and C3). It's the correct code or setup for the interrupt generation on the GPIO(pind). And How to use Interrupt Vector IDs which are mentioned in <ti/csl/soc/c6678/src/cslr_device.h> and <ti/csl/src/intc/csl_intc.h>.
We share the code, Please review it and give us any suggestions.
Warmest regards,
Krishn Singh Chauhan
