TPS82084: What is the behavior when high voltage is applied to the input voltage?

Part Number:TPS82084

Hi,

I'm considering using TPS82084 devices.
The specification is below.
A DCDC converter is also connected to the front of this device.
The device steps down the voltage from 24V to 5V.
As internal evaluation criteria, if the preceding device is destroyed and 24V is applied to TPS82084, if there is smoking or fire, the device can not be used.
So I would like to ask you a question.
If 24V is applied to VIN of TPS82084, is there a possibility of smoking or firing of this device?

(specification)
VIN : 5V
VOUT : 3.3V
IOUT : 1A
Best regards,

AWR1642BOOST: RCS computation

Part Number:AWR1642BOOST

The above diagram is a snippet I obtained from another post, about RCS computation. The last paragraph ("...For example if you would like to convert the peak value......") just gives a general overview of the process. This is however vague for a newbie trying to work around on your radar hardware.

Do you have a detailed tutorial on the calculation of RCS including the steps to be followed when using only the mmWave Demo Visualizer out of the box?

Hi all

Would you mind if we ask DRV8323?

Our customer will configure register data via SPI.
After Sleep mode(EN=low), does register data return to default setting?

Kind regards,

Part Number:DM388

Tool/software: TI-RTOS

Hi All,

We are using DM388 and IPNC3.9.1. We are facing grey scale issue with he Video coming out of the DM388 HDMI out.

Following are details.

1. The Mcfw pipline is Capture and Display.

2. Grey scale adjustment is bypassed in Register settings.

3. Input to capture link is through HDMI in which is getting data from HDMI out of PC.

4. Coefficients are Y_R_HDTV.

5. Output of HMDI out is RGB.

6. attached Images.(1. Direct from PC to HDMI monitor , 2. PC HDMI to DM388 and Then HDMI out of DM388 to monitor.)

Thanks

TUSB211: EQ level strength

Part Number:TUSB211

Team,

Would you advise that correction strength at EQ level
Disable <level 3 <level 0 <level 1 <level 2 (MAX)
Are they in this order?
If EYE does not open at Level 2, no further correction at this IC
Will it be impossible?

Also, I think there is another device TUSB212IRWBR,
Can the maximum of this EQ level be corrected larger than level 2 of TUSB 211?

Thanks

Best regards,

Hi Sir,

Our customer have two board need to connect,
But the connect sequence is 12V-->Signal-->GND Can not change.
So current product had Noise Malfunction or Damage issue.
Do you know TI LM5069 can be Delay time or PowerGood Delay function to Delay power on waiting 500m~1S into GND Connected?
Or TI have other better solution for this application? Io current maybe is 2~5A

Compiler/TMS320F28075: packing structures

Part Number:TMS320F28075

Tool/software: TI C/C++ Compiler

Hello,

my application includes packed structures to make communication easier. However I've seen that compiler doesn't accept the __attribute__ ((packed)).

Is there a different way (an attribute, a compiler option, a #pragma directive, etc.) to pack structures and variable inside structures with word alignment instead of long alignment?

Thank you.

Part Number:TIDA-01167

Hi

I have a question about the following texts  in "3.1.4 Circuit Behavior" of TIDA-01167's design guide.
I think that the correct one is not R1 but R3, right?

  "R1, R2, and D8 can be changed accordingly to support transient peak voltages."

Unfortunately, I did not get the brightness variation of LED in this code.

So, I want to know how to use this code to create another code of  breathing light?

I appreciate any help.

Hi:

    I'm debugging the ti_154_gateway_ibm code on the MSP432E401Y launchpad，there are  two questions as follows：

   （1）I don't understand why there are tasks and pthreads in programs，what is the difference between Tasks and pthreads；

  （2）Which is the highest priority？MqttClient and MqttClientThread have the same priority？

I have compiled my collector application without IS_HEADLESS, but cannot see any cmd:   on putty.

To type any command do i need any other configuration?

If i type in putty terminal it is showing command not found.

Can anyone guide me, how to do this.

DLPLCR6500EVM: Maximum frame rate in video pattern mode for 8 bit patterns

March 6, 2019, 2:38 am

Part Number:DLPLCR6500EVM

Hello!

We are planning to use a LightCrafter 6500 evaluation module for a biological application. Simply put, we want to use the system to project a video stream onto a biological sample. You can think of the video stream as a “movie” that may contain different sinusoidal gratings, spatio-temporal white noise stimuli, or even natural scenes. In any case, the according video stream would be provided in real-time by a Linux computer via a standard graphics card (i.e. we don’t want to load the video data onto the DLP prior to its presentation). It is important that we can rely on accurate presentation of the video stream (no alterations in terms of scaling, contrast, image "enhancements" etc. by the DLP). Additionally we need a precise trigger signal for each frame. We would need a continuous frame rate of 240 Hz for frames of 8-bit greyscale depth.

From what I learned from the datasheets and here in the forum the LC6500 should be suitable for this application. However, just to be absolutely sure that I understood everything correctly it would be very kind if you could briefly confirm that the LC6500 is able to stream 8 bit patterns in video pattern mode at approx. 240 Hz via HDMI. I found in the DLPC900 datasheet (dlpc900.pdf) that 8 bit patterns can be shown at 360 Hz with external input of the video data. While 240 Hz would actually be sufficient for us I wonder if the LightCrafter6500 evaluation system does actually support a frame rate of >=240 Hz when the video stream is delivered via HDMI. Maybe I just overlooked it, but I did not find any clear statement on this topic in the LightCrafter6500 manual (dlpu028c.pdf).

Thank you very much!

Hello,

I need help fixing a PRECISERR.Data Access Error that is happening in my ble5 simple peripheral project. I am using version 2.3 of the simplelink cc26x2 sdk. I have been trying to track down the problem following the debug guide up to the point where the exception information is inspected using ROV ( ). I have implemented a execHandlerHook method and the program eventually ends in that method. Unfortunatelly, I do not know what to make of the ROV data I can collect at this point:

Can anyone help me interpreting it?

CC2650: BLE Device Monitor: What does "Primary Service validation failed" mean? Cont...

Part Number:CC2650

Picking up where I left off some months ago...

When I add a custom Primary GATT service with random uuid (00000000-5578-4167-a937-787e755c37e1) to a BLE server the BLE Device Monitor (v2.9.0) connects to it OK but reports "Primary Service validation failed":-

And nothing is shown in the BLE Service/Characteristics window.

Could someone familiar with the BLE Device Monitor please explain what this message means?

Other clues:-

  • If I change the custom Service definition to Secondary, the other "Primary" services are correctly enumerated and listed by DeviceMonitor. The other primary services include one with a 128bit UUID.
  • Removing all custom characteristics from the custom service makes no difference to Device Monitor.
  • BTool v1.41.11 appears to enumerate all service and characteristics without any errors repotred. See below:-
