LEDSPIMCUEVM-879: LEDSPIMCUEVM-879 and evaluation software support capabilities

Part Number: LEDSPIMCUEVM-879
Other Parts Discussed in Thread: TPS92518EVM-878, TPS92518, , TPS92518HV

Can the out-of-the box LEDSPIMCUEVM-879 with the TPS92518 evaluation interface software support multiple TPS92518HV parts on the SPI bus? For example, I have to re-spin the TPS92518EVM-878 demo board in order to add functionality to be able to test the TPS92518HV per my requirements. I would like to add another IC for two additional drive channels.

thanks,

Craig

Hello Craig,

This should work either daisy chance or star. Star might be the easiest to try and it looks to support four addresses.

Hi Irwin, thanks for your response

Is there any auxiliary documentation regarding integration of multiple TPS92518 on a single SPI bus? For example, the only reference information is table 1, page 2 in the user's guide, SLUUBM0A through the jumper descriptions.

Where are the instructions on how to address TPS92518 1, 2, 3 & 4 devices using EVM GUI?

Hello Craig,

Sorry there's no documentation however you can write to individual addresses using existing FW. In order to do so you need to configure the jumpers as seen in the 2 attached pictures. In the pictures I have address 0 and address 1 but you can use whatever address you desire.
