Part Number: BQ25703A

Hello,

I am writing to ask about communication over I2C. Chip is not responding to it's address (0xD6).

I am adding our schematic file.

In given situation:

5V on PP_HV  makes REGN to go 5V but CHRG_OK pin stays low.

Questions:

Is there any error on the schematic that could affect I2C communication? (Pull-ups of I2C lines are on other part of schematic)

What is minimal operational configuration of BQ25703A chip? What pins do I need to connect to be able to communicate over I2C?

Best regards,

Wojciech Maćkowiak

HDC2080: The accuracy of rH and temperature while using HDC2080

Part Number: HDC2080

Hello TI,

As per datasheet HDC2080 sensor is factory calibrated to rH accuracy of ±2% and temperature accuracy of ±0.2°C.

But we are not getting the accuracy as mention in datasheet. The results we are getting, are varying up to ±10% in rH and ±4°C in temperature.

I need to know :-

1. As per datasheet HDC2080 have the accuracy of ± 2% in rH and ±0.2°C in temperature then what is the significance of rH and temperature offset concept of up to ±25 % in rH and ±20.62 °C in temperature.


2. If the HDC2080 have the accuracy of ±2% in rH and ±0.2 °C in temperature then what is the need of offset.


3. The accuracy as you are mention in datasheet is with offset or without offset?

USB 2.0 to USB 3.0

Hi TI

Our project needs two USB 3.0 interfaces, a USB 3.0 Host connects to a USB Camera, and a USB 3.0 Slave connects to a PC.            

But MCU RK3308 are all USB 2.0 interfaces, a USB 2.0 Host and a USB 2.0 OTG.           

I would like to know how we can meet the needs of USB 3.0. MCU does not have PCIe and other high-speed interfaces.           

Do you have any proposal?

Thank you.

TUSB8041: Behavior in connecting high data rate devices

Part Number: TUSB8041

Hi Team,

We developed the system having TUSB8041 before and the device worked as USB2.0.
Recently, new project was kicked off and we wanted to reuse the circuit but we faced following issue.

[Issue]

When connecting two high data rate devices to the hub such as USB camera, one USB device was stuck.

[Our guess]

We are guessing this issue is caused by a band shortage due to large traffic of the cameras.

[Questions]

Then I have two questions to solve this issue.

1. Is this HW issue or SW issue?

2. If this is HW issue, How much data rate USB devices can we connect to  TUSB8041 safely?

It's nice if you can advice me how to evaluate the system to eliminate this issue.

Regards,

Takashi Onawa

Hello, 

I am using ADS1232 for Weight scale functionality.

Used library : https://github.com/ciorceri/ADS1232

#define _pdwn 8
#define _channel 7

Setup information: 

In this we have made 2 separate channel , left side (2 load cell- half bridge) attached to channel-1 of ADS1232 and right side(2 load cell- half bridge) attached to channel-2 of ADS1232

In my application I want to get the left and right side weight , that values i will add in my code and get final user weight.

but in calibration of 2 channel at same time if I am trying to do then it is getting calibrated, but after sometime we stopped getting the correct weight. 

Kindly give some solution, how this can be done.

TMS570LC4357: Endianness for external memories

Part Number: TMS570LC4357

Hi,

From other TI posts got to know that TMS570LC4357 supports big endian and the endianness cannot be changed.

Also, the following was mentioned, 'the byte ordering is managed inside the MCU depending on the endianness. The external data bus connections need not account for the endianness change.'

But how will the microcontroller determine which endianness to operate in?

Page 329 of technical reference manual shows a read only bit 0 for 'ENDIAN', which determines the endianness.

Who will set this bit?  Is there any additional pin to determine the endianness?

As suggested, we are maintaining same external data bus connections (D15:D0 of microcontroller to D15:D0 of external memory).  Do you foresee any concern?

Archana Rao

Hello,
Q1. I want to create a project based on project_zero (SDK simplelink_cc13x2_26x2_sdk_3_20_00_68) that can be compiled by CCS and by IAR. The idea is to have several folders of source files (application, BLE, general, drivers, etc), folder CCS for compilation by CCS/TI compiler and folder IAR for compilation by IAR. What is the best way to do it?

Q2. I get original demo ble5_project_zero_cc26x2r1lp_app_syscfg project to workspace [project_folder]\CCS and built it. It was OK.
After that I move files project_zero.c and project_zero.h from  to folder  
\CCS\ble5_project_zero_cc26x2r1lp_app_syscfg\Application\  to  folder  \Source\Application\, add these files to Project explorer as  “Link to files” relative to PROJECT_LOC and confirm adding the new location to include path.

Clean build failed at the linkage stage (screenshot is attached). What is a problem?

Thanks,

It is observed that 2 transformers: (part num: 750342670, 750342671) and one Inductor(part num: 750342669) are not available in the market.
So can you let me know the detailed specifications of 1)750342670 2) 750342671 3) 750342669

I couldn't find them in internet and if I get them from Wurth electronics it will cost me and takes time. 

So let me know the specifications of the 3 part numbers provided. 

Hope you do so.

Part Number: TMS320C6678

Tool/software: TI C/C++ Compiler

Hello

i have two question to ask.

we tried different size of FFT (double, float, int32) inside dsplib of c6678 (version 3.4.0.0). we used TSCL of dsp to measure execute time of FFT. in all cases our measured time was 2 to 2.5 times greater than numbers reported in dsplib benchmark, here is first question:

1- what is source of this mismatch between our measured execution time and TI reported times (we implement our test according to all of TI recommendations)?

we also compared TI benchmark result of dsplib for 6455 to 6678. and Here is second question:

2- considering all of improvement in 6678, for example addition of more multiplier and ..., how comes that 6455 and 6678 performance are approximately the same (based on TI report numbers)?

Hello everyone,

I am creating an alg-plugin for my usecase over linux.

UseCase :- Capture -> Alg_ABC (DSP1) -> Display_M4 (IPU1_0)

I have referred FrameCopy for the development and followed the same steps for Linux. But when I include my plugin in cfg.mk at apps/configs path ,where all plugins are included for build , it is searching for SRC.MK file. But it is not being included in the plugin folder for the development over Linux (as per referred FrameCopy). 

Am I doing something wrong in here? Do I need to put the plugin folder at rtospath and create SRC.MK file specifying path for build ?

Following error has been given on the terminal :-

Makefile:51: /home/linux/Documents/SourceCode/vision_sdk/apps/src/rtos/alg_plugins/ABC/SRC_FILES.MK: No such file or directory

Hi all,
Trying to program and debug the MCU TMS320F28377S using JTAG debugger XDS110, but JTAG is not working debug mode showing the error in console window as shown below
IcePick_C_0: Error connecting to the target: (Error -2131 @ 0x0) Unable to access device register. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.0.27.9)  
Here iam enclosing the screen shots of both errors. I Have checked the JTAG connector and it is fine.
What could be the problem? please support.
Regards
Naveen
