Step 1: Flash the board Step 2: Getting the results of ultrasonic sensor Step 3: Power cycle the board by removing the USB and reinserting back. After this step 3 the board does not work or did not output until it is reflashed again. What could be the possible cause for this ?

I am able to perform basic measurements successfully using the FR6047_USSSWlib_template example project. I see that the ultrasonic measurement functionality is implemented in a precompiled library (.a file) inside the USS package. I would like to better understand and customize the measurement process, specifically: - ToF calculation (Tup, Tdwn processing) - Signal processing flow inside USS library - How algorithms are structured internally My questions: 1. Is the source code for the USS library (.a file) available under any license or request? 2. If not, is there any detailed documentation explaining: - Internal processing flow (capture → filtering → ToF calculation) - Key APIs and their roles 3. Are there example projects that demonstrate: - Direct API usage without relying on USS Design Center GUI - Minimal implementation for custom firmware integration? My goal is to integrate USS measurement into a fully custom application and possibly modify parts of the measurement pipeline. Current setup: - Device: MSP430FR6047 EVM - Medium: Water flow measurement - Tool: USS Design Center - IDE: Code Composer Studio (CCS) Any guidance on how to work effectively with the USS library or extend its functionality would be very helpful. Thanks in advance!MSP430FR6047https://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1626008/evm430-fr6043-hid-bridge-connected-waiting-for-deviceFri, 13 Mar 2026 11:04:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:535272c0-f497-435e-9c7b-fb0414b08d42Ralph SchenderleinPart Number: EVM430-FR6043 When I start running my evm430-FR6043 I first have to connect the device (USB).

I have seen very little written about this series of chips in the last 5 years. Seems like all the literature is from around 2017 - 2019 indicating the product maybe be superseeded by a better product, is that the case??

I use TI demo code in the IAR Embedded Workbench for MSP430 and I have customized the TI Demo code(Not USS module part is customized since it seems almost the same). But when it comes to USS module and measurements I have got stuck. i tested the Tone generation using the function USS_message_code debugCode = USS_startPPGToneGeneration(&gUssSWConfig, USS_test_channel_0); and I get a square wave if the transducers are not connected and when they are connected a different shape of continued waveform I got. And I received some continuous waveform as well. 1MHz wave form I get when the transducers are not connected. Received continuous waveform when the transducers are connected. Yellow - Transmitting Tone, and Blue - Receiving Signal waveform. Do they make sense? They seem to have a DC part, is it okay? Then I got in to the design center mainloop, USSLibGUIApp_Engine(); and chose to go with removing __ENABLE_LPM__ and in the USS_startUltrasonicMeasurement(&gUssSWConfig, USS_capture_power_mode_low_power_mode_0); function. As the TI family guide says, we can't debug the intermediate steps inside the USS module, we can not go to debuggermode without turning off the USS module working properly, so we need to go from start transmition to capture and convert the captured data straight without going to debugger, as per my understanding as TI says. (Am I correct in here?). Since my customized bord don't have a HMI, I used UART and created a send error code function using UART, so the loop continuosly run and I can see the error code it is given using a receiving python script as well (Confirmed that error code by full cycle runnging one time using a breaking point at the end and using watch option for the error code in the debug mode). my problem is I get stuck in void commonWaitForconversion(USS_capture_power_mode_option mode) and can't debug in the middle as I get the error message of stopped by the debugger. I normally debug the working of a code step by step, but can't do it in here. I wanted to first watch if the excitation occurs as it is defined in the TI demo code (20 excitation pulses with no stop pulses I guess). But can't even see it either. I am not sure whether it excites (Tone generation works though) because the power on register bit USSPWRUP can't monitored as well. (I am using IAR Embedded WorkBench for MSP430 and MSP430FR6043) What should I do, Could you please help me with this?msp430fr6043https://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1617222/msp430fr6045-pin-status-of-controllerFri, 13 Feb 2026 16:49:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1c5085bb-0192-4ead-97d9-53dc71f83090HARSH PALIWALPart Number: MSP430FR6045 Hi, As mentioned in datasheet about status of unused pins of controller to be output low 1.Is there a particular reason to it? 2.If i am using Two modes and when am using the same pin in one mode and wont be using it second mode should i configure it still as output as it be unused during that time or can i keep it as input to reduce current consumption.MSP430FR6045Energy infrastructurehttps://e2e.ti.com/administrators1/ultrasonic1/f/ultrasonic-sensing-forum/1617134/evm430-fr6043-evm430-fr6043-connection-issue-custom-msp430fr6043-pcb-unable-to-handshake-with-uss-gui-via-evm-ezfetFri, 13 Feb 2026 11:13:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:f47997c7-9ac0-429d-b63c-b0d2758ba479Nilotpal BaruahPart Number: EVM430-FR6043 Other Parts Discussed in Thread: MSP430FR6043 , UNIFLASH Hello TI Team, I am currently developing an ultrasonic flowmeter solution using the EVM430-FR6043 evaluation kit and the Ultrasonic Sensing Design Center (USS) GUI . I have developed a custom PCB based on the MSP430FR6043, which has been hardware-optimized (removal of headers, LCD, etc.) for size reduction. I am encountering an issue where the USS GUI fails to detect my custom board, despite successful firmware flashing and verified hardware connections. Below are the specific details of my setup, the issue, and my troubleshooting findings. The Issue I have flashed the standard USS Gas demo firmware (downloaded from TI.com) onto both the EVM board and my custom PCB using Uniflash. EVM Board: Connects to the USS GUI without issue. Custom PCB : The USS GUI displays "HID Bridge Connected -- waiting for device" and fails to proceed. I have attached the schematic of my custom PCB for your reference. Hardware Configuration & Wiring To program and communicate with the custom board, I am using the ezFET section of the EVM430-FR6043. I have removed jumpers J1, J2, and J3 to isolate the EVM MCU and established the following connections between the EVM ezFET headers and my custom board: Comms : EVM (RXD/TXD on J3) → Custom Board (TP18 RXD / TP19 TXD) I2C : EVM (SCL/SDA on J1) → Custom Board (SCL/SDA on J1) Control : EVM (RST/TEST on J3) → Custom Board (TP1 Reset / TP20 Test) Interrupt : EVM (IRQ on J1) → Custom Board (IRQ on J1) Power : EVM (VCC/GND) → Custom Board (TP21 VCC / Pin 6 GND) Key Observations & Anomalies During troubleshooting, I observed a discrepancy regarding I2C addressing that may be the root cause: I2C Address Mismatch: Despite flashing the exact same firmware image to both boards, an I2C scan reveals different addresses: EVM Board: Detects at address 0x48. Custom PCB: Detects at address 0x0A. Question: How can the identical firmware result in different I2C slave addresses on the same MCU model? Logic Analyzer Analysis: I intercepted communication between the working EVM and the GUI. The GUI appears to perform Read/Write operations on address 0x0A . When attempting the same with the Custom PCB, the bus shows 0xAA + NAK . Verification Steps Taken To ensure the custom hardware is functional, I performed the following standalone tests: Basic Functionality : Flashed a simple LED blink code to both the EVM and Custom PCB. Both worked successfully. I2C Hardware Check : Verified the physical I2C lines on the Custom PCB by communicating with an Arduino Uno. The hardware lines are functional. Could you please assist in troubleshooting why the Custom PCB is rejecting the GUI connection or explain the I2C address discrepancy observed between the EVM and the custom hardware? For your reference, I have attached the datasheet to this post. Thank you.
