AWR1642BOOST: mmWave Sensing estimator: Bandwidth, active frame time and cube size
Part Number:AWR1642BOOST
Hi,
While using mmwave sensing estimator, I had the below doubts and suspect on some inconsistency.
1. Bandwidth: I would like to know how the bandwidth is calculated. As per the literature, the bandwidth = speed of light/(2*Range resolution). If I keep my resolution as 50cm. by this formula the bandwidth comes to 300MHz. But the sensing estimator says 345.82MHz. I assume this is some buffer of some kind. I would like to know what calculation goes behind this value. I also noted that the value decrease, if I reduce the number of transmitters. I would like to know this relation also.
2. Active frame time : This is more of a doubt and confirmation. When I increase my no of transmitters, the active frame time remains the same. Is this due to the fact that the chirp time reduces to half? Is it true that when transmitters increase, the chirp time is reduced to fit in the next chirp from the other transmitter but the full active frame time is kept constant??
3. Radar cube size: I see that the radar cube size remains the same irrespective of the no of transmitters I use. I cant really think of an explanation for this.
Thanks in advance for the help.

TDA3XEVM: Bitmap Transparency on GRPX Overlay
Part Number:TDA3XEVM
Hi all
I could see that i can change the globalAlpha to change the opacity of entire overlay.
Is it possible to draw individual bitmaps with custom opacity value, drawn with Draw2D_drawBmp.
I need to keep the opacity levels of other text/bitmaps drawn.
Is there any usecase in vision sdk implemented a similar drawing method?
Regards

MSP432P401R: MSP432 Bluetooth plugin SDK OAD example Explorer APP unexpectedly quit
Part Number:MSP432P401R
Hi all,
I using MSP432 LaunchPad + CC2650 BoosterPack and flash OAD example of simplelink_msp432_sdk_bluetooth_plugin_1_20_00_42
to update MSP432 firmware by SimpleLink Explorer APP.
I refer to Over-the-Air Download code example user guide.
step1. I can get MSP432+CC2650 Device (MSP432 OAD) by Explorer APP.
step2. Upload SAP image.
In OAD user guide, it uploads a "pz.txt file".
I confused that where can I get this one. is this application txt file generate by CCS?
the captured image I upload "pzz.txt" ( generate by CCS's Out Format Options) via Google drive.
Next, I pressed "Begin Update" Button to download firmware.
Unfortunately...the Explorer APP unexpectedly quit...
Regards,
Tim.

TPS54231: There is a shock wave on the TPS54231 output 5V, and the audio frequency is on the audio, so the sound can be heard from the speaker
Part Number:TPS54231
Hi ：
I use TPS54231 in my product,the chip input voltage between 20V to 26V, the output voltage 5V for a digital amplifier power supply(the digital amplifier PN is VA2101) .The horn connected to the amplifier is 25.
Problem: there is a shock wave on the TPS54231 output 5V, and the audio frequency is on the audio, so the sound can be heard from the speaker.
1,、Adjust the C27,C28 ,R36 value, have no effect;
2、If I add a 510 Ω pseudo load on the 5V, the fault disappears.
3、If adjust the input voltage for TPS54231 lower than 24V, the noise will disappear, as long as the input voltage is higher than 24V, 5V shock wave back again.
In the product, I can not add a pseudo load. Do you have a good solution to this problem?Thanks a lot！

BQ25898: Connecting SYS Output of two BQ25898 devices together
Part Number:BQ25898
Hi
In our design I am using two independent and identical, charger (Bq25898) and battery (18650 - Li-Ion) configuration.
The system output (SYS) from each charger is tied together and connected to load.
MSP430 configures the charger devices independently. I use this configuration, to isolate the battery in case of failur.
I am planning to do isolation this by disabling the charger using CE# pin / EN_TERM (REG07.7) and by disabling BATFET.
In evm when I pulled up CE input the charger functionality is not halted, but the software configuration worked well. Please clarify?
I have following queries on the design too.
1. Is it recommended to tie the system outputs of two identical chargers together?
2. In case of failure in battery will it draw power from SYS through BATFET if is isolated by software by BATFET_DIS (REG09.5).
Thanks

TPS2553-1: About "TPS2553's ILIM pin function check"
Part Number:TPS2553-1
Hi, team.
My customers are planning to use TPS2553DBVR-1.
My customer is trying to check the Current Limit Function, please check with the confirmation method below and tell me whether there is no problem.
＜Question＞
Is there no problem with applying 5V from the outside to NO.5 pin?
※Customer try to "apply 5 V to the pin 5 to make a pseudo overcurrent condition and confirm that the output voltage of the 6 pin stops".
※The customer did not mention the conditions of IOUT, but I will separately tell you that there is a minimum load of 100 mA even if shorting ILIM to IN by me.
Basically, I understand that the description of the application of external voltage is not included in the data sheet, but since the customer is focusing on "ILIM short to VIN", I want you to tell me.
Best regards,
Masumi Sekiguchi

Hi,
My name is Idan and I'm electronic engineer.
In my application, I need to simulate the electrical behavior of an actual long power transmission line (~600V, several Amps) and long serial communication transmission line (RS485, ~1MSPS). My main primary tool for electrical simulation is the TINA-TI tool…
Any suggestion for a complete model of this kind of transmission line?
Thanks a lot,
