Using the TMP104 Software

Reading from Registers

When first starting the TMP104EVM software, the user should confirm stable connections to the test board

by toggling the Power button to provide power to the TMP104. Then, the user should press the Initialize

button, as shown in Figure 12. The Number of TMP104s box should change from a 0 to a 4 to indicate

that all connected TMP104s have assigned themselves an address on the UART daisy-chain.

To check the status of all registers, press the Read All Reg button; see Figure 13. If the device is

functioning correctly, no error messages are displayed.
