i2c.scan() implemented as multi-byte writes #10

Open charkster opened 2 years ago

charkster commented 2 years ago

I was not able to detect the VCNL4010 ambient light sensor, as it will not ACK to a write to an invalid internal address (0x00 is not valid). This has the effect of the sensor not being detected from the i2c.scan() function. A further look at the i2c.scan() function sees it implement as multi-byte writes, which is not the spec recommended I2C quick commands.
