Part Number: TCA9548A
Other Parts Discussed in Thread: DRV2605LEVM-MD, , TCA9554

Hi Team,

Our customer is configuring DRV2605LEVM-MD thru Arduino and would like to clarify about the value of Register at Section 6.1 of the User's Guide in the link below. The value of Register in Table 4 and 5 are N/A, what would be the command to enable individual and all the channels 1-8?

Hi Danilo,

The TCA9548A does not have multiple registers like the TCA9554. It only has one control register so in order to configure this device you would just send the I2C address followed by whatever command you would like to the control registers. The control register is configured as follows:

For the board you are using the code 0x99 (10011001) enables channel 1,4,5, and 8.

Hopefully this helped.

Best,

Chris
