TPS61050EVM

Hi Eli,

you mentioned the lighting LED - You mean the LED on the Board right? Is the LED of the USB-TO-GPIO Adapter lighting?

The screenshot shows in the right lower part the status of the interface as not functional. Do you see a chance to have try with a different USB Interface?

We are double-checking at the moment with our software group what can cause this behavior.

Kind Regards,

Florian

Hi

Yes, the led on the board.

Led is not lighting 

They tried two different evm on two computers the result is the same 

Thanks 

Emi,

thanks for the information's.

Did they try a different I2C Interface as well?

Do you know if the status LED of the USB-GPIO Interface is green?

Regards,

Florian

They got two EVMs on different time so they had to to try different I2C interface

Hi Eli,

I get the same message as you have when I try the software on my PC.  The reason is that I have Windows 7.  Windows 7 is very different from the Windows XP or 2000 that the software was designed to run on (page 2 of the EVM UG).  So, the software will not work on Windows 7.

Are you using Windows 7 or another OS besides XP/2000?  Would it be possible to try using Windows 2000/XP?

Also, is the green light on the USB box on?  If it is not on when it is plugged into the computer, then you need to try a different USB box.

Hi Chris,

So if we have only Win. 7, we will not be able to to use TPS61050 EVM. correct?

I will check regarding the USB plug.

Correct.  The current software will not work with Windows 7.

Could you supply the customer's LED driver specs to make sure you are evaluating the best device?  If the TPS61050 is the best fit, then we can see about updating the software to work on Windows 7.

Hi Chris,

 need to drive a WLED at 150mA, and 500mA peaks. Vin=3.3V

The operating LED voltage: 4.0v -  5.4v, OVP above 5.5V

Hi Eli,

thanks for the Info's. 

Do you know if your customer has a chance to use an XP-based computer for the moment? It takes a bit of time to have a Win7 GUI available.

Florian

Hi Florin,

No, they do not have XP.

B.regards

Eli
