TMP117EVM: Dual sensor GUI not working

Part Number: TMP117EVM
Other Parts Discussed in Thread: TMP117

I trying to connect two TMP117EVM to one computer and run the TMP117dualsensor_GUI 1.1.0, One board is configured with address 0x48 and the other 0x49.

I have downloaded and installed runtime 7.2. But I can not connect to any of these boards, is it suppose to work? I tried two different computers with same problem.

When I use TMP117EVM_GUI 1.3.0 it works fine.

Hi Jon,

The dual sensor gui connects to two TMP117 devices on the same I2C bus. We don't have the capability to connect to two TMP117EVMs on USB. You can separate one of your TMP117s from the controller and wire it to the other TMP117EVM's controller.

thanks,

ren

Hi Ren

I totally misunderstood the setup. Anyway I soldered the boards to the same controller with wires but it still didn't work.

After that I changed the I2C pullup resistors to 1k5 and now it seems to work fine, thanks.
