Part Number: UCD3138

Hi

when AD01 input voltage is a little negative, what's the ADC result? it is 0V or a large number?

thanks.

Part Number: INA226

hi TI team:

I wonder if the INA226 internal ADC has the parameter like effective resolution or peak-to-peak resolution?I can not find them in the datasheet. If possible ,i want to get the noise value Vrms & Vpp,too.

I would appreciiate it for the help,thanks.

Part Number: ADS1256

Hi,

I am working in continuous mode for single channel measurement at higher rate 30KSPS.

I am giving sine wave as input to ADC AIN0 channel.

Raspberry Pi is communicating with High Precision AD/DA ADS1256 board over the SPI.

I am using C program got it from github.

SPI clock is 1.92MHz.

I received 30Ksamples at output.

The issue is ~ 10K output samples  are noisy.

The datasheet says If there is a step change on the input signal while continuously converting, performing a synchronization operation to start a new conversion is recommended. Otherwise, the next data will represent a combination of the previous and current input signal and should therefore be discarded.

Is this statement applicable to Sine wave.

I also tried for constant DC input. I got same behavior.

Thanks in advance.

Part Number: TMDXIDK5718

Tool/software: Code Composer Studio

I am creating a boot program for MPU (A15) using "TMDXIDK5718".
I want to measure the processing time of a function in a program.

I tried the following code, but the return value of the “clock” function was always “0xFFFFFFFF”.

clock_t start = clock();
func();
clock_t end = clock();

I think I should use the "Performance Monitor Count" register.
But I don't know what code to write.
Could you provide a sample code like the one above?

Thank you.

Part Number: AM6548

Hi

Currently, I'm facing the trouble to transfer the data from PCIe to DDR/SRAM.
I'm using RTOS SDK and GP AM65x EVM.
Received data via PCIe in AM65x are stored in DDR on GP AM65x EVM or SRAM in AM65x.
Sometimes, writing to memory (DDR or SRAM) is skipped.
(Skip means, There is an memory area where writing is not performed halfway.)
It happens at various 32-byte boundary locations.
It doesn't happen at the same address every time.
It happens about 1% wit DDR and 5% with SRAM.

As far as memory test to DDR or SRAM, RW problem is not happen.
Therefore, I don't think the issue is from memory side.

Question1:
 The error register value when the phenomenon occurs is:
     PCIE_EP_UNCORR_ERR_STATUS_OFF=0
     PCIE_EP_CORR_ERR_STATUS_OFF=0x10C1

  What does above error mean?
  Is it related this behavior?

Question2:
Is there any other register to confirm the status to verify the issue?

Question3:
Is there any recommendation to solve the issue?

Thanks and Best regards,

HaTa.

Part Number: UC2844

Hi,

My customer use UC2844 in their new design, 346VDC input,24V2ADC output. during the test, They found the Vds voltage of the MOS is up to 770V. They don't know the root cause and how to reduce this voltage. below is the schematic, transformer spec and Vds waveform. please kindly give your suggestion. thanks.

Part Number: CC1310

Hi Team,

I have some confusion about FEC of CC1310. There are multiple posts about this question, but i can not find a exact answer.

https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/554583   

As the answer of Richard from the above link said:  In the CMD_PROP_RADIO_DIV_SETUP command, FEC is a unfortunately a misnomer, since it enables manchester encoding and not forward-error-correction. And i checked the TRM which also proves this: 

And i learned that LRM already uses FEC from this post: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/825990

So my question is :

1. FEC automatically is enabled/disabled or can be manually changed?

2.If it's automatically enabled/disabled, which mode can also support FEC,do we have a list?

3.If it can be manually changed, which parameter/API can achieve this?

Thanks in advance!

Part Number: TAS5731M

Some of the products shipped burn out the woofer.

Could you tell me what's the reason  the woofer burn out？

Is it related to the register-setting of the TAS5731？

Part Number: CC3220SF

 Hello,

I am working on CC3220SF launchpad module.Working on wifi doorlock refer tidc-01005.which was designed for cc3220s but i have changed it to cc3220sf. which is working on SWD programming SOP setting is 001 on launchpad board.

1. I need to flash the code into cc3220sf  that is on power reset the code should boot from flash which is not happening now its running on SRAM .i need to debug every time when the power reset occurs code dosen't boot.

what is the way to flash it like for production mode.

2. Right now i'm debugging and dumping my code via Code composer studio and i'm not not able to dump the .bin file of my project via uniflash.

i dont know the cause when i try to add the file in uniflash 

 the bin file(507Mb) using Uniflash as it is throwing the Error

Error:MCU Image file exceeds the maximum size for this device

i will attach the map file here 

(Please visit the site to view this file)

3. i have also tried dumping the .bin file via uniflash session using CC3220SF_SWD.ccxml file. getting below error

Part Number: CC2541

Hi Team,

A customer meets a problem when implementing SBL on CC2541, and he locations the problem to bin file. There is a warning when generating bin file: Warning[w28]: Parts of segment <XDATA_ROM_C> 1 are initialized (as in module ?FILLER_BYTES), parts not (as in module simpleBLECentral). Which leads the bin file can not be download via SBL.

Hi,

I recently migrated to simplelink SDK version 3.3 for cc1352R1. When I try to pause debugging code, I'm getting the error mentioned in the thread title. I'm attaching the screenshots of code and disassembly.

The message "UART1 Initialized"  was printing.

How to fix this?

Hello expert,

Customer would like to know the OTP behavior and I cannot find datasheet for it. Would you kindly help to describe the behavior for us? Thanks a lot!

Best regards,

Ann Lien

Part Number: FDC2214EVM

I use FDC2214 EVM .

I would like to ask about the coils mounted on the evaluation board.

Despite the large space on the back of the evaluation board, components such as coils are mounted on the surface.
This is not a design point, is the coil placed on the same side in consideration of the sensitivity of the sensor?

Is it a problem to consider two as a pair and mount one on the front and one on the back?
(I feel like there is no problem if the gap between front and back is shielded with GND.)

I think that the actual size of the coil is quite large, but is it possible to make this coil a small coil with similar specifications? (Is there a problem?)

I would be happy if you could respond.

Regards,

Part Number: VCA2615

Hello!
We have some questions when using vca2615rgzt. I hope you can give me some help and answers.
Problem: we use vca2615 as part of automatic gain control. Under the condition of almost the same input and output, the maximum difference of VCNTL control voltage of different vca2615 is 0.2V. According to the corresponding curve relationship (as shown in Figure 1), the VCNTL difference of 0.2V means that there is a difference of 5dB magnification. However, the gain error in the chip manual is - 1.5dB and + 1.5dB (as shown in Figure 2).
I would like to know if the 5dB difference in gain between vca2615 devices is normal.
The schematic diagram of our vca2615 part is shown in Figure 3.
Main configuration of vca2615:
LNP Gain(G1,G2)=11;
FB(1-4)=1111;

Vcainsel - used to time-sharing switch the signals of ChannelA and ChannelB to VCAoutA and complete sampling.
Relevant tests we conducted:
Input signal: 3.7mhz sine wave (input from a and B in Fig. 3)
Amplitude: less than 1mV (stable)。
We use an oscilloscope to measure its waveform, through FFT test to the corresponding waveform amplitude corresponding DB value. DB value of signal at each test point. Through their differences, it is found that the VGA part of the chip is the main error source. I'm not sure the VGA part of this error is reasonable.
Table 1 is the data of our test quantity (converted to DB value through FFT function of oscilloscope)

The related schematic diagram and test data are in the attachment word.（I can't upload my schematic and data in this frame）

i can not write success the value ,this question take me two days 

maybe write is not success or read is not success;

Part Number: INA220

Dear team,

Here is a question from the customer.

They read back the data through I2C every 500ms. The conversion period of our chip is about every 500us. So, there are about 100 samples during a read period. So what will I get when reading back data? The average value of these 100 samples?  Or RMS of these 100 samples?  Or just the last value of these 100 samples?

best regards,
