Other Parts Discussed in Thread: TMP117, USB2ANY,
Hello!
I have a TMP117 EVM and I want to connect it to two thermal sensors on flex PCB. I've broken off the tmp117 using the perforation, connected the USB and whats left of the evaluation board to a perforated circuit board, and to the circuit board I wired two identical 6 pin FPCs -- the only difference I made was in the connection. For one FPC, I jumped pins 4 and 5 together, and on the other I jumped pins 5 and 6. I currently have pin 1 unconnected, 2 to SCL, 3 to SDA, 4 to V+, and 6 to GND (with 5 being connected to V+ on one FPC, and GND on the other) [ see image if unclear-- bottom row of numbers is related to 0.5 mm side of the FPC]. When I connect the USB to the computer I get the following error: "Connected to USB2ANY Controller, but failed to connect to device TMP117 on I2C @0x48".
Any suggestions? I have tried connecting both FPCs directly to the evaluation board and got the same error message.
