EVM430-FR6047: how to use the EVM430_FR6047 kit

Hi CS,

It sounds like you either don't have your transducers properly connected or you don't have the correct parameters configured in the GUI.

The EVM430-FR6047 How to use guide, section 2.0 shows where to connect the transducers.  There are some basic configuration instructions located at this <link>.

Also, check out the TIDM-1019 Water reference design document

Thank you for the reply.

However, even if you change the settings by referring to the manual you gave, an error occurs.

To check the connection part of the ultrasonic sensor, ADC input test was performed as shown in the attached picture.
As shown in the figure, two voltage values ​​are assumed to be the input values ​​of the ultrasonic sensor, and I want to check the status of ADC Capture for the two current voltage values, but the same error occurs. (CH0-voltage1, CH1-voltage2, GND-voltage ground)

Is ADC test impossible on EVM board?
Or do I have to do the ADC test in another method?

Again, please provide the pin numbers and related examples to test the ADC operation.

Hi CS,

Let's focus on getting the USS operating properly first.

When you do an ADC capture in the GUI, do you see something like the capture below? The peak amplitude should be ~900 (ignore the 22% threshold in the picture for the moment). I just want see if your parameters are configured properly for your transducer and pipe so the ADC is capturing the waveform correctly.

If you don't see a waveform similar to this, then the USS configuration parameters are not set correctly for your transducer/pipe. What transducer are you using?  What is their operating frequency, 1MHz, 2MHz, etc?

I don't see a pipe (flow tube) in the picture.  Can you show what you are using. Do you have water in the tube with no air bubbles?

Next, regarding your transducer connections, from the pictures you show it appears you have them wired correctly.  Here is a diagram:

Regarding the ADC measurements, the SW is complicated and I honestly don't know the details to point you where to look.  Are you looking only for the ADC measurements?  Not absTOF, dTOF, flow rate, etc?

Thank you for answer. We are conducting EVM experiments for ultrasonic flow measurement and electromagnetic flow measurement.
Question 1) I want to know if it is possible to connect to the EVM board to check the operation of the electromagnetic flowmeter (attached file). The technical documentation says to connect P1.0 or P1.1 to use ADC1, but the LED is connected to the EVM. I would like to know how to connect pins to simply read ADC values.

Question 2) Please explain again in detail how to connect the ultrasonic sensor and how to connect it in the attached circuit diagram.

Hi Huron,

You do realize that the picture you are showing is not an ultrasonic transducer.  It is a rotary pulse flow meter that generates a digital pulse train based on the speed of rotation caused by the water flow. This EVM is not designed to use this type of sensor.  You would typically use an MCU's Timer with capture/compare feature to measure this type of sensor.

Thank you for the reply.

ENV430_FR6047 Can't do ADC test on board?

I want to run the ADC example (msp430fr60x7_adc12_21) using the P1.1 pin on the ENV430_FR604 board.

I want to know how to do it.

I'm trying to run the example(msp430fr60x7_adc12_01) you gave me, but I was wondering how to connect the pin(P1.1/A1) to the EVM430-FR6047. How do I connect the pin(P1.1/A1) to the  EVM430-FR6047 board?

Hi Huron,

Here is graphic showing where to make convenient connection to P1.1/A1.  You must remove resistor first.
