I have a question that I hope can be clarified. I reviewed the source code of the Studio CLI and saw that at line 330, as shown in the image, the field bReorderEnable is set to FALSE. I would like to ask what the function of this field is — specifically, what does it reorder? Does it reorder so that the output bin file has the format Q1I1 Q2I2 Q3I3 Q4I4 instead of Q1Q2 I1I2 Q3Q4 I3I4? Or does it reorder out-of-sequence packets so that the raw.bin file is generated in the correct order? If it is currently set to FALSE, what would change if it were set to TRUE? Thank you.https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1655110/pga460-q1-not-getting-echoSat, 13 Jun 2026 08:59:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:88d98c5e-8a7d-4090-b423-a177dc75b688Jaya ShreePart Number: PGA460-Q1 Other Parts Discussed in Thread: PGA460 Hello TI Support Team, I am currently working with the PGA460-BOOSTXL EVM along with the transducer daughterboard. I have carefully followed the step-by-step instructions provided in the official TI setup video, but I am unable to receive any echo signal in the GUI. Here are the details of my setup: Hardware: PGA460-BOOSTXL Evaluation Module with the included Transducer Daughterboard. Software: PGA460 EVM GUI. Problem: The device does not register or display any echo data during a burst/listen command. I have attached a screenshot of my GUI window showing my current register settings, thresholds, and the blank echo data plot for reference. Could you please help me troubleshoot why the echo is missing? Let me know if you need me to verify specific jumper configurations, register values, or supply voltages.building automationPGA460PGA460-Q1https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1655099/lm26lv-q1-no-polar-point-for-the-markingSat, 13 Jun 2026 02:51:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:1e23cd08-1ceb-4eab-9c24-019d37399cabZhang WeiPart Number: LM26LV-Q1 LM26LVCISD-135/NOPB, customer pn:136E5-S080070H-00 for this part the engineering team suggust have polar point for the marking. it will be central for the SMT mounting.PC &amp; NotebooksLM26LV-Q1https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1655097/iwr6843aopevm-inquiry-regarding-iwr6843aopevm-for-research-applicationsSat, 13 Jun 2026 01:31:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:e0a41b54-9c4c-4d68-b7eb-f52dec5fad38Albandari MohammedPart Number: IWR6843AOPEVM I have an inquiry regarding the IWR6843AOPEVM module for research purposes.

The broad group of chemical compounds that fit into the definition of PFAs is quite large and includes over 20k unique substances. The above information does address some subgroups of PFAs substance that are currently regulated. TI continues to invest in research and engage with peers, suppliers, and consortia to better understand the full scope of PFAS use in the semiconductor industry’s manufacturing processes, and to develop effective alternatives, where possible. Today, there are no technically or commercially feasible alternatives to PFAS used in several key semiconductor manufacturing process areas. To learn more, please visit the Semiconductor PFAS Consortium&#39;s website. https://www.semiconductors.org/pfas/ TI continues to work with our suppliers in an effort to procure non PFAS-containing products. TI is committed to using the safest materials possible in our manufacturing processes and to operating in a socially thoughtful and environmentally responsible manner. Hope this helps gives a little more context here!

In the meantime, could you try using shutdown/one-shot instead of continuous conversions? The datasheet does state that the one_shot bit always reports 0 in continuous mode. It doesn&#39;t need to be read. thanks, renhttps://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1653646/awr2944p-macronix-external-flash-integration-with-ti-fls-driver/6381568Fri, 12 Jun 2026 21:23:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:2279bdc3-43fc-49be-861c-545bc75f0d2aAnanya K CHello Hadir, Please open this E2E in the Vector forum.

Please select the COM port corresponding to “AR-DevPack-EVM-012” with the highest COM number. In the screenshot below, the highest available COM port is COM60. If the connection does not work with COM60, try the next lower AR-DevPack-EVM-012 port (COM59, then COM58, and so on).

I understand that there is limited SW support for the AWR2243 2X CAS EVM. Is there more support for the AWR2188? This radar would provide the angular resolution my work needs, but I understand it is also very new. Does it have real-time visualization capabilities?https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1654942/fdc2214-question-list/6381464Fri, 12 Jun 2026 19:43:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0ae781f3-cb31-4ef9-ad44-8bc5cf514becChase GirardHi Mingkang, Thank you for reaching out and I would be happy to help you with your customers questions. I&#39;d actually like to suggest the FDC1004 as a better fit for your customer&#39;s application. The key reason we recommend it is that it features an active shield driver, which provides better resilience against EMC/EMI interference. Measurement Principle: The FDC1004 uses a direct capacitance measurement approach (no LC tank needed), with a built-in offset DAC to cancel parasitics. Range is &#177;15 pF with up to &#177;96 pF offset compensation. Channels: It has 4 independent channels that can be configured for single-ended or differential measurement. Differential pairing is great for noise rejection in sensitive mechanical sensing applications. sampling &amp; Noise: The FDC1004 supports three selectable sample rates: 100 S/s, 200 S/s, and 400 S/s, configurable via the RATE register. The noise floor is approximately ~10 fF RMS at the lowest rate (100 S/s). PCB Requirements: Power Supply: The FDC1004 operates at 3.3V. A decoupling capacitor (typically 100nF) placed close to the VDD pin is recommended for power supply filtering. Crystal Oscillator: Not required — the FDC1004 has a built-in internal 4 MHz oscillator. MCU Matching: The FDC1004 communicates via I&#178;C (up to 1 MHz), so any MCU with an I&#178;C interface and 3.3V logic is compatible. PCB Layout: Keep sensor traces short and use the active shield driver output to guard sensor traces, minimizing parasitic capacitance and EMI noise pickup. If you have any additional questions please let me know.

If the customer is planning to use an external oscillator then they should follow the specs in the datasheet. But if the customer is seeing the spur and looking for a workaround then they need to use an external TCXO oscillator. Most of the TCXO oscillator has supply voltage starting from 1.2V to up to 3.3V. To summarize, any issues with the spur please and workaround is needed then use TCXO oscillator with a larger voltage swing and if there is no spur issue but customer wants to use an external oscillator then please use the DS specs. Examples of TCXO oscillator : https://www.digikey.com/en/products/filter/oscillators/tcxo/172?s=N4IgjCBcpgHAzFUBjKAzAhgGwM4FMAaEANwDsoAXAJwFdCQB7KAbRABYwAGANgCZuQAXSIAHClBABlagEtSAcxABfFUA Thanks, Ahanafhttps://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1652038/awr2944evm-unable-to-get-something-work-on-the-2944evm/6381369Fri, 12 Jun 2026 18:05:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:dc3387ac-0c5c-4745-aff9-3fa9543ab220CesarHi Neha, I checked other threads in this forum and did not see similar issues thank you Cesarhttps://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/1654426/iwr1843-aoa-calibration/6381366Fri, 12 Jun 2026 18:04:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:93c68e8f-fe60-476d-bd35-0244e4fe35fcCesarHi The mmwave sdk 3.6 does not have to support dialectric lens.
