TPA3113D2: Shutdown at startup when set to minimum volume

$

Part Number:TPA3113D2

Hello,

I am having a strange issue where when I apply power to my circuit, if my input volume is set to minimum (zero) the TPA will shut down and not restart. If I apply power with the volume turned up slightly operation is fine and I can then set the volume to minimum with no issues.

thanks,

Part Number:PGA411Q1EVM

Hello ,

I can see that for PGA411Q1EVM resolver to digital converter that  Exciter frequency (10 to 20 kHz), but ı want to use 5 kHz for Exciter ( ref+ ref- coil terminals ). Can this PGA411Q1EVM  module provide that frequency? Excatly I want to use Exciter frequency from 1 kHz to 10kHz.

Part Number:MSP432P401R

Hi

I have found some posts to the effect that there is no example code for the display I bought with my l launchpad.

There is some talk about an older example but it is not clear where to find the example and how to run it.

It sounds like this has something to do with SimpleLink. What is SimpleLink do I need it and how would it avoid it.

I tried a MSP430FR5969 a few years ago with CCS v8 and I do not remember the term SimpleLink from then. 

Thanks

bq40z50-r1

hello

I programing bq40z50-r1 with "bqProduction Smart Battery Builder" software 

after programing passed successfully ,Then at a zero current test I saw there was a current  between 8-10 ma 

In  the software --> "calibration Type" i choose Boar offset Who had to help me with the calibration but it not

when i made manualy ""cc offset" it help and the current saw 0 ma

And another thing that makes it difficult for me to perform the calibration correctly is that the designated software

does not have the option to perform ""cc offset" .

How can I avoid this problem in the future because my burning process is automatic?

Is there any new software of  "bqProduction Smart Battery Builder" or Can be add the "cc offset" function In existing software?

Please, your reference

Best Regard

DP83848I: Connection of DP83848i

Part Number:DP83848I

Dear Sirs,

My customer asked us about connection of DP83848i.

He wants to know the connection propriety to the backplane at a later stage of the slave side PHY.

We have received a request from customers to connect on the backplane without using a pulse transformer.
He wants to connect the master and the slave with a backplane instead of connecting them with a cable.
The connection is as shown below.

Please tell me whether it is possible for your request, and if possible, how to do it.

Best Regards,

CC1350: Single-Ended current consumption

Part Number:CC1350

We are presently using the CC1350 powered 1.8V with a single-ended configuration for a 868MHz and 2.4GHz output (external bias). What is the expected current consumption during TX and RX for this configuration?  Do you expect a differential output with 3dB back-off to consume more current than the single-end output described?

Linux/PROCESSOR-SDK-AM57X: Issue in building tisdk, can't download ti-cgt-pru

$

Part Number:PROCESSOR-SDK-AM57X

Tool/software: Linux

I have build the tisdk several times before and this was always working without issues.

But since this weekend I can't build it anymore. Normally I do "MACHINE=am57xx-evm bitbake core image-minimal"

But it gets stuck on a do_fetch of ti-cgt-pru-2.2.1.

So i did: "MACHINE=am57xx-evm bitbake ti-cgt-pru" and I see that wget can't download the file from the TI site.
I also tried it manually with the wget command but also this is failing. I can download the file with my Firefox browser but wget is failing. I see it is redirected to another download site but it fails after a timeout.

I don't use Ubuntu but I tried several machines that all worked before. To me it looks like an issue with the TI website.

Part Number:CC3220MOD

Hello experts,

We want to know whether the mentioned behavior could be avoided.
Could you tell us the following statements are defined as a 802.11 standard?

- Null packet is sent from CC3200MOD to go into the power save mode.
- The prediction which consumed 100mA in 50-60ms couldn't be off.

Part Number:DRV10983

Hi

Our customer wants to implement circuit that can detect direction of motor which is spun by external torque.

I think it is possible to determine by monitoring phase of two different FG signal.

However, I have no such a reference.

Do you have any reference or other solution?

Part Number:TMS320F28379D

Tool/software: Code Composer Studio

Dear support,

We would like to communicate with FPGA via SPI/DMA  - same as it is done in Example_2837xD_Spi_dma.

in Control card all work good, but I don't understand why there is no calling of InitSpiaGpio() function?

Which GPIO is configured for SPI_A. I would like to see in the scope clock, chipSelect, dataIn & datsaOut .

Or I missed something here...

Thanks,Sabina

Part Number:AM3358

Hi,

I have a question from my customer for detailed information about EtherCAT slave bug (PINDSW-2636) fixed in v1.00.06.
http://processors.wiki.ti.com/index.php/PRU_ICSS_EtherCAT_Release_Notes#Fixed_Issues

Usually such information is available below wiki document, but PINDSW-2636 is not written. And it seem the wiki is now read only.
http://processors.wiki.ti.com/images/9/92/EtherCAT_Slave_Errata_PINDSW_01_00_06.pdf

Could you update the document and add PINDSW-2636 info.?

Thanks and regards,

Part Number:UC3845

In the datasheet P3 Device Comparison Table.

UVLO of UC3845 was described Turn-on at 8.4V and Turn-off at 7.6V.

On the other hand , in P8 Electrical Characteristics .

It seems like there are 2 type of spec. Turn-on typ 16V & 8.4V and Turn-off 10V & 7.6V.

Which is correct spec ? Are these value Turn-on 16V and Turn-off 10V typo ?
