WebMay 1, 2024 · The touchscreen I2C device AR1020/1021 interrupt line connects directly to the IRQ2 pin of the LS1021a. Using the default ar1021_i2c.c driver that comes with the QOIOQ-SDK-2.0, I manage to get the driver loaded and probed but I can't figure out the correct interrupt number to use for the IRQ2. I randomly use WebStep1 – Select The IO pin and Edge. First of all, we’ve to select the IRQ pin that we’ll be working with. In our PIC16F877A, there is only one dedicated pin for external interrupt requests RB0. And there are some GPIO pins from PORTB sharing an IOC (interrupt on change) request. For this tutorial, we’ll be using the RB0 INT.
