OPT3101EVM: Request to check firmware related problems

Part Number: OPT3101EVM
Other Parts Discussed in Thread: OPT3101

Hi

My customer is testing the EVM firmware to apply the op3101.

We are currently experiencing the following issues and would like to request assistance.

1. Please check firmware to proceed initialization to internal temperature sensor (external temperature sensor can not be used due to future unit price problem).

2. When the physical address A0 is 3.3V, and A1 and A2 are 0V, check the firmware as below.

dev.regProgDevice._controller.sendPacket ('DEVAx5 <8>', 'Change I2C Slave addressAddress')
VS
dev.regProgDevice._controller.sendPacket ('DEVAx58', 'Change I2C Slave addressAddress')

    Hi,

    1. The configuration actually does use the internal temp sensor for the calibration. Both internal and external values are read by the latte GUI, but external is not needed. Additionally firmware only acts to relay commands from latte PC software to the OPT3101 so all these settings are in latte rather than the firmware.

    2. The second option is correct. You put the address as 0x58 not 0x5<8>

    Best,

    Alex
