Part Number:LM95071
Hello,
Can you confirm if the LM71* and LM95071* devices are "100% compatible" at the software driver level?
I consider adding LM95071* as additional source to the LM71* that we currently use, and need to confirm interchangeability between the two in our 3.3V,SPI applications.
From what I read, only significant difference will be better accuracy from the LM95071.
Thank you!

I am currently developing a IoT node device using TI products. For that i need a wifi module or wireless microcontroller which works as access point (AP) and client mode in same time like ESP8266 modules. In ESP 8266, there are 3 working modes such as 1) AP mode, 2) Client mode and 3) AP+Client mode. I need the third mode operation in TI devices. Please suggest the suitable device. Thank You in advance.
Part Number:66AK2G02
Hello,
I am currently working with the K2G EVM and while trying to get a GPIO to work, I noticed that there is a mistake in the GPIO documentation. GPIO pin mappings should run from 0-31, 32-63, 64-95, etc, but there seem to be an offset of 1 as specified in section 11.7.6.14 and onwards (j = 32 to 64 should be j=31 to 63).
Have confirmed this by toggling a pin via an emulator.
Thanks
Part Number:AM3354
Tool/software: Linux
hi ，I would like to use arago-base-tisdk-image-am335x this file system, support GPU, because it is smaller!
I installed the GPU driver from SDK 2.0.00.07 /board-support/extar-drivers/omapdrm-pvr-1.9.2253347
I copied some of the libraries needed from tisdk-rootfs-image-am335x-evm.
I installed the compiled QT5.5.0 library
Insmod omapdrm_pvr.ko then ./usr/bin/pvrsrvinit
But when I run QT app, it will appear
./qtapp:/lib/libstdc++.so.6: no version information available (required by /usr/lib/libPVRTrace.so).
what should I do?
Part Number:TXB0108
Hello,
I am looking for an octal bidirectional level shifter 3.3V TTL to 5V CMOS.
For reliability issues (the IC will be used in a measurement instrument) I need to control the direction with a direction pin and I don’t want the IC to sense it automatically.
I have found the TXB0108 but it only translates from CMOS (not TTL).
Other ICs I have found are SN74GTL2003 and LSF0108-Q1 but they both have automatic direction detection.
Do you have any suggestions?
Many thanks.
Best regards,
Francesco
Part Number:TAS5766M
Dear Sir,
Can we setting TAS5766 both L/R o/p be L channel content? or both be R channel content?
Thanks, Ian.
Part Number:OPT8241
Hello,
I've seen in answers to other questions that TI suggests ARC coated F1.1 or F1.2 lenses optimized for 850nm with CRA < 20 deg. For OPT8241 image format is 1/3" (sensor area diagonal). Are there any OTS solutions for these types of lenses? If not, are there suggested manufacturers of custom solutions?
I contacted Soft Kinetic who provided the lens for the evaluation kit and they informed me that since they were bought by Sony, they no longer provide outside design services. I've also talked to Sunex with some limited success.
Thanks,
Scott

Part Number:TM4C1231H6PZ
Hello,
I am calculating period and on time for an input signal using capture and compare timers. I have two inputs that happen to be connected to WT4CCP0 and WT4CCP1. I have both channels monitoring input signals at the same time. WT4CCP0 calculates the signal parameters without error. WT4CCP1 does well for the most part, but periodically will calculate a 0 on time. I have the on time calculated in the timer ISR. I have attached this code. Can anyone see any issues with the code that may produce this error?

Part Number:DAC7613
Tool/software: TI C/C++ Compiler
I have read the DAC7613 datasheet.
The function of each interface of the chip I had understand.
When I write code acrroding to Digital Input Timing and Data Output Timing, the output always show 1.5v.
So, I hope someone can tell me how to use DAC7613 and give me a sampl code.
I am using Atmega128A Atmel Studio 7.0.

Part Number:CC3220SF-LAUNCHXL
Hi! I'm reading the various documents about dev board, examples, out-of-box, uniflash, etc... but I'm still stuck in at a very simple point.
I don't need the provisioning/mobile stuff: my application will read the credentials from a file. Right now they are simply hardcoded.
I'm able to compile, launch and debug my application from CCS on CC3220SF-LUANCHXL.
Now I want to use UniFlash because:
GOALS
WHAT I DID
It downloads the image to 96% then fails with this error:
Operation failed: fs_programming error: ret:-10372, ex_err: 2633 - FS_WRONG_CERTIFICATE_FILE_NAME
I don't understand why. I disabled the secure mode for both device and mcu file.
QUESTIONS
Any further advice or specific documentation is welcome!
Part Number:AFE5809EVM
Hello TI people,
Our aim is to get 16 bit I and Q on LVDS output.
Here is the setup
We are using external signal off 500kHz sine wave at INP1 (Channel 1).
Onboard clock - 40 MHz
Power supply +/-5V
DC removal is bypassed.
Could you please answer these questions as the voltage levels previous applied hasn't given any results.
1. What should be the voltage level of the input signal? In this case, we are using sine wave. We are not using VCA or LNA.
2. How to setup down conversion frequency to 300 kHz using GUI?
3. How to setup decimation factor to 32 to get sampling of 1.25MHz?
Thanks!
Part Number:F28M35H52C
Hi,
I need to check wPWM module for my project. I've taken the ePWM example code (epwm_updown_aq) for f28m35x and tested. But when i probe the EPWM1A/B(PA0_GPIO0 & PA1_GPIO1), EPWM2A/B(PA2_GPIO2 & PA3_GPIO3) and EPWM3A/B(PA4_GPIO4 & PA5_GPIO5), i'm not able to see the waveforms in an oscilloscope.
ePWM1 are mapped in GPIO0, ePWM2 in GPIO2 and ePWM3 in GPIO3.
I've tried many times but not able to get the waveforms.
Please suggest any ideas.
Thanks

Part Number:TPS61169
I'm having trouble using part number TPS61169DCKR to drive just one IR diode part number VSMB294008G at 100mA. The IR led is a high powered one that can take 100mA and my VIN is 3.3V. The data sheet says V FB is 204mV so 204mV/100mA = a 2.04 ohm resistor. With this resistor in place driving the LED I disconnected the one side and measure 250mA instead of 100mA going through it. Any idea why?
Part Number:CC3200
Tool/software:TI-RTOS
I want to make use of CC3200 SDK's standard Transceiver Mode Application example to build a simple test bench for wifi modules. I noticed that it takes 3 seconds to send out 10 packets on a channel with the rate of 1Mbps and more than a minute to send 200 packets. Each packet has 22 bytes (176 bits). Shouldn't it need only a small fraction of a second to send out these packets?
Is there any hard coded packet sent interval that can be tuned to increase the throughput?
Part Number:TMS320F28069
Tool/software: Code Composer Studio
Hi Team,
I would like to describe my new mission task as you asked:
First I would like to inform you what we did till now:
We are developing in code composer studio - for the device TMS320F28069, c2000 family [compiler version: TI v6.4.10],
We are now have a software that runs from flash (the main knows to upload most of functions from flash to ram),
The programming to flash is now done automatically by code composer and JTAG.
The current mission is to know to program the output image (that code composer generated) from host computer (windows) via serial to the device,
The method that we would like to do it is as following:
1) We need a host application that loads the .out file (that code composer generated) and sends it to the device by SCI.
2) We need to write a second boot flash programming application running from FLASH SECTOR A of firmware that program to FLASH SECTOR B (the data is downloaded via SCIA from host).
this serial stream is in fact our current software that now needs to be ran from SECTOR B.
My question is:
I need a detailed guide that tells me:
1) What host application I need in order to load the image and send it to SCI, and how to use it.
2) Example in the device site of how to write the code that gets the serial stream and programs it to FLASH B
Thanks,
Shlomi
Part Number:CC2650MODA
Hi,
i try compile ble_sdk_2_02_01_18/examples/cc2650bp/simple_np/iar
new IAR 8.10 use wchar_t size 4 bytes but library use wchar_t use 2 bytes.
Under IAR 7.80 all compiled fine.
How i can recompile libraries under IAR 8.10 ?
Best regards
