Hi,
I am still using 3.20 Sdk for RTLS, while I wait for 3.30 guide. I would run calibration in Python receiving raw data. I have read the documentation but I would be sure I am right.
In raw mode, I should:

Goood day,
I would like to know the difference between the code TPS7A6050QKTTRQ1 and TPS7A6050KTTRQ1 without Q.
Thanks

Hello,
We are using TI RTOS and NDK library for an ethernet connection to the server. We are using NDK ndk_2_25_01_11 and TI RTOS tidrivers_tivac_2_16_01_13.
Can we use two ethernet sockets to communicate with two servers in parallel? Does the NDK library is reentrant?
Thanks.
Part Number: TXS02326A
Hello
I 'm trying to start an I2C interface with the TXS02326A device but not yet successful.
TXS02326A and bq25895 are connected to I2C bus on our board.
The bq25895 device has the 0x6A address and answers on the i2cdetect utility request but
the TXS02326A device does not answer on the i2cdetect utility request.
Here is the result of the working i2cdetect utility (the i2cdetect utility from i2c-tools packet):
# ./i2cdetect -y 0
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- -- -- 6a -- -- -- -- --
70: -- -- -- -- -- -- -- --
We see that the bq25895 device is defined and the TXS02326A device is undefined.
I checked all contacts - that's all right.
I soldered a new TXS02326A chip, but nothing has changed.
The SDA and SCK signals are pulled up through 10k to 3.3 V.
I have questions, help me:
1.
Is the Single Write and Single Read the same as on figure 21 and figure 22 for bq25895? (The
i2cReadWrite.png file for bq25895 is attached).
2.
The IRQ signal is involved in generating the TXS02326A device address.
We connect the IRQ input/otput directly to our processor and set the low level.
Then I set RSTX input to low level and then to high level. Then I run the i2cdetect utility.
Is it right? This sequence true?
I think there 's some problem with forming an address here, but what I can 't understand.
Thanks in advance

hi,
hi give me the right file to read Tusb422 and bq25713 through I2C,
i have written code for I2C read operation but it is not working, so give me the right file to read I2C using repeated start. and without repeated start.
thanks
Part Number: LMR14020
Hi team
Here is the design I develop for monitoring the MCU VCC. I use TPS3702 to monitor the MCU VCC and shunt down the LMR14020 by connecting the OV pin to EN pin when the MCU VCC is too large.
1. so here I want you to help check the schematic.
2. Especially whether the Rpu(10k) is appropriate, because the Rpu used in the reference design of LMR14020 is usually hundreds of K. I don't know whether the Rpu(10k) I selected is appropriate, and how to find the maximum input current of the EN pin of LMR14020 from datasheet.
Best Regards

Hi,
Is MCAL provided for CC26xx family of devices? One of my customer would like to know if this provided.

Part Number: UCD90120A
The datasheet states that pullups resistors are required, and the evaluation kit indicates selectable resistors for 2k2, 1k or FLOATING, but on the USB transceiver side, while the UCD part has actual no series or pullup resistors on that sheet.
The documentation references PMbus and/or SMbus, but in between all those specifications and TI information, the pullup resistors could be as low as 680 ohm. I would expect that a minimum that 4k7 resistors would have been specified. What is the actual requirement here on the value of pullup required?
Part Number: TPS3702
Hi team
I use TPS3702 to monitor the VCC of TMS320F28062 . I connect the UV to MCU RST pin to reset the MCU when the MCU VCC is under 2.9V and connect the OV to LMR14020 EN pin and the gate of NMOS to shunt down the DCDC and SN74HC244 when the MCU VCC is over 3.6V .
1. Could you please help me to check the schematic?
2. helping me check if there is any timing problem of this design
3. helping me check if the Rpu value is appropriate
Best regards

Hi,
Can we test ADC working using test pattern & which pin we need to monitor the verify pattern outputs (TESTO_1 or TESTO_0 or any other pin)

Good Morning,
I am using power suite to develop the 3 ph Vienna rectifier and would like to use more than proportional control.
I have opened the stand alone Compensation Designer but how does the code get updated?

Hi,
In my application, I need to switch ON and OFF Power(3.3V at 1A max-3.3W) to another IC through GPIO of the controller(3.3v), I initially had chosen TPS22919 which has 1.5A continuous current. But when I calculated the Max Power dissipation as per the datasheet is given in 11.3 Thermal Considerations which has a max P dissipation of 0.5W.
Looking for a Power load switch for this application.
Even the TPS22810 says max Current of 3A and max P Dissipation is about 1.6W at Ta-23C.
(Is my calculation wrong?)
Thanks.

Dear TI expert,
we are using a OPA124UA chip, but the chip will soon stop production. Please help to recommend a pin to pin product, thank you
Hi,
I have questions about boot sequence including bootmode setting.
When we checked the EVM board, We saw the result as the below.
1. Should the bootmode be set between time to high of soc-poz-out and time to high of pmicout-porz?
2. If mcu-uart-rx signal is high between M2 and M1, is it ok?
3. When we connected mcu uart on our board, kernel crash was occured. Is it related to boot sequence or question 2?
please give me a comment!
Thanks,
Manwoo Kim

Part Number: CC3135
Hello everyone!
What are the supported file types for the HTTPS server? (especially interested in .js, .svg, .xlsx, .csv)
My previous project included the cc3100, where I had some trouble with the limitations of the http server/ file system.
In this document: http://www.ti.com/lit/ug/swru368b/swru368b.pdf
on page 78 it mentioned these limitations, but I cant seem to find these informations regarding the 3135.
Also, I would like to get more informations on the https server tokens.
What are the maximum amount of tokens per request, and what are their max sizes?
Best regards,

Hi Team,
My customer is about to evaluate TIDM-HV-1PH-DCAC board but it seems that app center is forcibly shut down when trying to install "GUI Composer Runtime v1" as below.
Could you check the reason why the app center was forcibly shut down at the timing?
Here is the error log. (Please visit the site to view this file)

Part Number: ADS58J63
I see that in Page 80h, register address 53h, bit 7 - it says enable "Divide by 2" for proper operation of ADS58J63.
Does it mean that I have to supply 1GHz clock to operate ADC at 500MSPS? Please clarify.
