I have a project I'm working on that involves an nrf51822 communicating with the optical sensor from a mouse. The pinout of the opical sensor seems similar to the ADNS2620, but the exact datasheet is not available. The datasheet for the ADNS2620 seems to basically say (but not explicitly say) that it uses I2C - unless I'm not understanding it correctly.
I've established an i2c scanner on my nrf51822, and it is (as far as I can tell) properly scanning each address (1-127) to find a device, but is receiving to response. I'm left to question if the optical sensor even communicates over i2c - and if not, where do I go from here?
Pointers appreciated. Thanks.
