TDC1000-C2000EVM: Help to setup the TDC1000-C2000EVM with the GUI

Part Number: TDC1000-C2000EVM
Other Parts Discussed in Thread: TDC1000, TDC1011

 Hello,

I am testing the module TDC1000-C2000EVM using a transducer of 2.4MHz, and I tried to follow the steps in this document

I connect just one transducer as transmitter and receiver, and I do not receive any eco signal. Is correct connect TX1 and RX2 in mode 0 or TX1 and RX1 in mode 1, to have connected just one transducer? 

I connected the transducer to TX1 and GND on Mode 0 into the J5 connector.
I saw this document, and I need to do application N#1 Fluid Level (see page 5)


In that document on Figure 5, it is connected TX and RX, my question is that if I have to connect TX1 and RX2 to the same terminal of the transducer and the other to GND on mode 0 ?
Also which is the recommended configuration for this application on the GUI?

Regards
Heiner

    Hi Heiner,

    Since you are using only a single channel for fluid level measurements, connect your transducer's positive terminal to the TX2/RX1 net, and the negative terminal to GND. The TDC1000 datasheet "Table 3. TOF Measurement Modes" clarifies how to configure the TOF_MEAS_MODE and CH_SEL for single sensor operation.

    In the case you connect to TX2/RX1, set TOF_MEAS_MODE=0, and the CH_SEL=1. This will make the active TX channel TX2, and the active RX channel RX1.

    The TX2 and RX2 pins are made common by the R80 0-Ohm resistor on the board, so you can connect the transducer positive terminal to J5-pin14.

    For a single channel version of the TDC device, you'll want to eventually use the TDC1011 for your end-application.
