Part Number: AM4379

Hi,

I recently updated our yocto image to the most recent TI SDK Version 6.x. The prior version we are using was the Version 5.2.x. After the update the Wifi/Bluetooth device is not probed anymore. I do not have any mlan0 device anymore after running ifconfig -a.

Following some additional information and logs. I have also attached the full dmesg log.

Please let me know if you need any further information.

Hi, 

Our project use a mcu connect to cc2541 with uart, mcu run linux, and we need develop software to control cc2541.

It seems we need use CC254X_PC_Examples as reference code, but we can't access the web page now, where can we get CC254X_PC_Examples source code, thanks.

Part Number: TIDM-SERVER-PWR-MON

Hi Team,

I am trying to port the existing code to IAR 7.1 and followed the document in the below post. Still I am not able to get through and got struck with linker error. can you please help in fixing the same.

Part Number: BQ24610

Hi,

We are using a BQ24610 to implement a LiPoly battery charger, the IC works fine until the battery is fully depleted. To protect the battery pack, we are using a S-8252AAG-M6T1U protection IC from ABLIC. when the IC detects the cells go below 2.8V it will turn OFF the discharge MOSFET to protect the cells from over discharge. SO far so good, the problem comes when AC is reconnected. The charger does not resume the charge, we can see in the scope that the charge perform the detection porcess since we see a 500ms duration pulse in the battery voltage line and also a 125mA current, since we are seeing this pulse during 500ms and the battery voltage goes to 5.8V during this period we assume the charger detects the battery. 

This conclusion comes since the algorithm says it will check that the VFB votlage to be below Vrech and if the timer expires it will sucessfully detect the battery. Since we are seeing the full 500ms pulse we assume the timer expires, the problems comes that after detecting a battery connected the charger is not charging at full charge or even at Iprecharge...the question is Why? WE assume that after detecting the battery the charger should go the precharge since the battery is at 5.8V (around 2.9V per cell since is a 2 cell battery pack) which is way below the VlowV of 6.2V (1.55 X 4 = 6.2V... since the voltage divider at VFB has a 1/4 ratio).

Can you explain why the charger is not pre-charging the battery? Does the TTC pin has any influence on the pre-charge process? As far as I understood the precharge is independent and it will work for 30 minutes to charge the battery at a low current so recover the battery and then start the full current charge cycle.

Can the battery detection be disabled? I saw another thread saying that in section 9.3.23 says how to disabled it but it does not say anything...it only explains how it works.

Are we missing something?

I have an application which sends messages between ARM-DSP using IPC messageQ,

I am looking for a way to shutdown the DSP in case the ARM side is terminated.

Also is there a way to reset the DSP from ARM ?

Part Number: MSP-FET

Hello, guys!

I am designing a custom board where we will use the MSP-FET to develop and debug a new firmware project and I have the doubt about the power pins, vcc_tool and vcc_target?

Which is the best way to connect them? It is probably that sometimes the msp430 would be powered by a battery and another time with the mps-fet vcc_tool pin during the developing. I don't know if the msp-fet internally detects the external voltage so it cuts its own vout, or if i need to use a diode to "separate" the external vcc from vcc_tool.

What do you recommend us?

Many thanks in advance and best regards!

Hi TI prof,

    We'r migrate our linux app from qt5.6+linuxfb to AM5728(Wayland+weston+qt5.9).

The app is working good on the old platform. Any widget can receive kind of  focusOutEvent() or focusInEvent() from QT.

The app is migrated on AM5728, it can run smoothly.

BUT,

      There is no  QEvent::Focusxxx, and can't access focusOutEvent() or focusInEvent().

What did I missed? It's related to QT conf or Wayland conf or sth. else?

Thx in advanded!

Part Number: TPS53622

Hi Support,

We issued a i2c(smbus) read command  to tps53622  ex:  #i2cget -y -f 0 0x60 3

then tps53622 asserted SMB_ALERT# right away, we'd like to know is it a normal behavior due to offset 3 is a write only register ?

PS#  not only offset 3, read at different offset would make SMB_ALERT# get asserted,  however  register 0,1,2 would not assert SMB_ALERT#

thanks

Part Number: DAC7811EVM

Hi.

I am using DAC7811EVM board.

I would like to increase the slew rate of DAC7811 output.

OPA 2277 on the evaluation board has a low slew rate.

So, I chose BUF634a with a high slew rate.

Part Number: BOOSTXL-AOA

Tool/software: Code Composer Studio

Hi,

I did many experiments about AOA for serval months. But so far I don't have a good result for my Indoor location project that make me feel inspired. Here are some questions I think I should make clear.

1. When I tried the RTLS-AoA demo, I found that if the distance between RTLS-PASSIVE and RTLS-SLAVE was too far (just big than 30cm) , the angle would have a frequent drift . If the distance was smaller the 30cm, the angle was relatively stable. If like that , I  think I can not use it for calculating the indoor location.

2.For the 1th situation , within 30cm, if I put my hand to the middle place of the PASSIVE and SLAVE board, the angle also had a frequent drift. 

3.The RTLS demo is based on that RTLS-MASTER connects to the RTLS-SLAVE ,and then RTLS-PASSIVE receives the I/Q sample for estimating the angle, I think this model doesn't fit to be used for the actual applications. Because if in a big place there should be many RTLS-MASTER for being used to cover the place,let's say there are 3, if sometime a connection of RTLS-Master1&Slave lost and it should be switch to the RTLS-Master2 cause of the smaller distance, In this situation, the connection establishment must will take time, and position delay will happen.

I think if the angle estimating can be achieved only through RTLS-SLAVE and RTLS-PASSIVE (like SDK2.3 demo : slave as AOA sender, passive as AOA Receiver) , it will be good for the actual application.

4.When I tried SDK2.3 AOA Demo, the angle was not stable but drifting very well(even though the distance was within 30cm ), I can not stand this, why.

5.I found SDK2.3 AoA Sender sending a BLE4.2 packet was always changing its content data ,from [11] to the [30] bytes, not fixed 0xFF, I found it by an Android BLE scanner APP,  but I could not found where it set these advertising data in the source code. According to the doc, 0xFF byte would be used to make 250khz constant tone, am I right? 

6. when I captured only one antenna I/Q samples by SDK2.3, I found that, for the 16 samples of one sampling period, the phase-difference between sample[n] and sample[n+1] is not a fixed number, sometime big, sometime small. I think if it have a perfect 250KHZ constant tone, phase-differcence between sample[n] and sample[n+1] should be 2π/16=0.125π. For one 4us period if it is not capturing a perfect 250KHZ tone, I think even it it 245KHZ, the phase-diff should be a fixed number between two contiguous samples. But actully not.

Bwteen two sampling of two periods(sample[n] and sample[16+n]) ,they are not the same to be a perfert continuous sine wave. 

7.When I calculation the phase -difference between Antenna1 and Antenna2 using the same index of sample[n] , it is bigger than π/2, in theory ,it should not happen, why?

What I should do?

Part Number: CC1101

Hello, 

We are investigating a problem we are observing with the CC1101 RF Transceiver in a battery operated setup and could use some help.

We observe that when the setup is running for a few days, the deviation of the RF signal decreases for certain parts of the transmitted signal. Attachments of this mail illustrate the measurements made.

The setup has the following relevant parameters:

• The CC1101 is used for 868MHz operation
• In FSCAL2 field VCO_CORE_H_EN is set to high in addition
• In MCSM0 field FS_AUTOCAL is set to 1
• Expected deviation is 50KHz

For testing purposes, I have also enabled the SCAL strobe before going to TX to perform manual calibration, but this does not resolve the issue observed. The errata was taken into account.

We expected the issue to be caused by some calibration issue of the VCO, but are not observing improvement. Could you elaborate on this issue? 

Many thanks for the response.

Part Number: AM5728

hi,

we have three video sources for capturing video in AM5728 through VIP module, but loading of modules is different in each instance of boot.

I need to have a fixed routine, so that capturing of video will be similar in all boot instance.

Because of randomization of module assignment, video capturing of particular video varies for each instance.

please suggest any method for fixed routine of module assignment.

Part Number: ADS8881

Hi there, 

we are referring to TIPD115 and it design files (sch. pcb, etc) to design a quite  similar data acquisition system, we ues THS4521 to drive ADS8881 too .

When reading section about Anti-Alias-Filter , I have some questions. Hope some TI expert could help.

1. On page9 of  SLAU515A, it writes "output impedance of the driving amplifier is equal to Ro ". Does Ro refer to open-loop or close-loop output resistance of the amplifier? How do we get this value from amplifier's datasheet?

2. As in SCH, Ro seems to be  10ohm (R7 and R8) as below. Why equation (38) in SLAU515A take Ro=80ohm  ? 

3. Also in SLAU515A, equation (37), why R_switch of ADS8881 is 220ohm, I think it should be 96ohm as in ADS8881 datasheet.  Finally, I think  ti should be R_FLT < 96ohm/20 = 4.8ohm ,and R_FLT >10/9=1.1ohm.

4. I noticed some other SAR ADC which does not provide R_switch value. what can we do with this situation ?

5. I also googled a very good tech note of TI on this SAR drive topic: "", it mentions on 2004 TI has senimar discussed this in details. Could you pls help where could I found this 2004 tech seminar PPT doc?

Hi, I'm a student researching Physics in Univ. Seoul, Korea. 

I'm looking for an element to amplify 10 ns-width pulse signal to around 100 V  (if possible up to 160 V ) 

But I couldn't find one having both (high speed) and (high voltage output) ability. 

Are there available one? or other possible way?

----------------------- current situation -----------------------------------------------

Input signal type: ~10 ns width pulse (5~10 ns)

Input voltage level: 30 mV ~ 30 V  ( I will choose a proper one to the element )

output voltage type: AC or DC :  If Peak to Peak voltage is above 160 Vpp,  AC or DC both are ok. 

                                                    If not, I prefer DC

Tool/software: Code Composer Studio

I am using Autmotive Toolbox 2.6.0.
First I used all the basic scripts/configuration files. This works perfect.

Then, in CCS I have set the value of the variable "ODDEMO_MAX_ZONES" to 5. I did this in the file "oddemo.common.h" (both in the DSS and MSS project).
After this change I rebuild my project: no error occured. 

I flashed the EVM with the newly produced firmware.

Then I changed the configurartion file: changed zoneDef so that I can use 5 zones.
In MATLAB I have set the value of the variable "len" to 5 within the function "getOccupDemoDecision".

I can now run od_demo.m without errors, but the first 2 zones are responsive. The other 3 don't react to activity.

Does anyone know what I should change in order to get 5 good working zones?

Hello Expert,

My customer has question for TMCS1100.

This device used  hall effect for current sensing.
However they have concern for that whether this device has any measures against magnetic intensity and RF signals?(e.g. internally shielded)
Dose this device has measures for these?

I'm looking forward to hearing back from you.
