OPT3001-Q1: Configure GPIO interrupt in Opt3001

Part Number: OPT3001-Q1

We are using custom board with jetson nano, we need to configure interrupt functionality in opt3301 in latched window style comparison mode, as per data sheet we need to clear a bit every time when interrupt occurs. Can you specify which register to clear when an interrupt occurs, and we can do it on the driver side? Also, explain any additional settings that need to be configured for this mode on the driver side?


  • Hi Krishna,

    When an interrupt appears in latched window style comparison mode, the INT pin can be cleared by reading the configuration register (pointer 0x01). This can be done on the driver side since it is just an i2c transaction. No additional settings need to be done to configure this mode.

    Thank you,
