Part Number: CC1120
Hi,
My customer would like to disable buffer amp, which inputs analog signal to CC1120, during sleep in sniff mode. In this situation,
1. Can the device output any right signal to control disabling the amp? How should user set the register to do it?
2. Can the customer use RBIAS voltage to disabling the amp? The background of this question is that the customer observed RBIAS voltage level is changed by the sleep mode.
Best Regards, Taki
Part Number: TDA3XEVM
Hi.
The MMUs for the DSPs doesn't seem to generate the correct PC value in the MMU_FAULT_PC register when a MMU exception occur. On the M4 I catch the exception but am only able to read this register as 0x0. I'm running on the EVM board with a XTDA3SXXABFQ1.
Does the same error exist for the production parts as well (TDA3x)? Is there a workaround or a scenario where this register contains the correct address?
With best regards,
Mattias

Hi,
From this json struct at wifi_thermostat example, is the "temperature" a topic, in which at AWS IOT Console ->Test I can view the temperature data?
temperatureHandler.cb = NULL;
temperatureHandler.pKey = "temperature";
temperatureHandler.pData = &temperature;
temperatureHandler.type = SHADOW_JSON_UINT32;
temperatureHandler.dataLength = sizeof(int);
Should I use this below instead to publish to a topic?
aws_iot_mqtt_publish()

What is the difference between the AM5728BABCXA and AM5728BABCXEA
Part Number: TUSB212
Hi Sir,
Could you please help to reconfirm the capability of our TUSB212 redriver?
Customer is asking if their trace are too long for their trace length.
PCH to MB connector around 11.x inch + 3.x inch to IO connector + IO board to output is around 3.8 inch.
Total trace will be more than 18 inch, is it suitable we use TUSB212 for their design?
And what is your suggestion for the trace length before redriver and after redriver?
BTW, for their design would you suggest them to put redriver on MB(close to connector) or IO board?
Thanks,
George
Part Number: TRF7970A
I am using the TRF7970A with our RFID application.
Intermittently, when the power is applied to the antenna, the IRQ is asserted and the SPI bus is locked.
CHIP_STATE_CONTROL (0x00) followed by (0x21)
Are there any precautions that should be taken when turning on the antenna?
Hi,
I`m currently developping a battery-management-system for a standalone device and need help to find a fitting TI reference design. Since I'm new in this field and the variety of available Charcher, Power Path Manager, Fuel Gauges and Protection Circuits is to large I'm struggeling to get started with the projekt.
Some specifications:
single cell LiPo, 2000-5000 mA/h
Input: USB or up to 12V power adaptor
Output: 3.3 to 5V, 0.1 to 0.5A
If anyone could share some experience, I would really appreciate it.
Greetings Flo
Part Number: MSP432E401Y
Hi, my application uses the NDK httpClient library to post requests to a web service over the Ethernet connection for the MSP432E401Y chip. Recently I switched from NDK non-secure to secure and the flash memory footprint of my application swelled from approximately 100kbytes to a whopping 400kbytes!. This happened by simply switching
status = SlNetIf_add(SLNETIF_ID_2, "eth0", (const SlNetIf_Config_t *)&SlNetIfConfigNDK, IFPRI);
to
status = SlNetIf_add(SLNETIF_ID_2, "eth0", (const SlNetIf_Config_t *)&SlNetIfConfigNDKSec, IFPRI);
in my ethernet hooks netIPAddrHook function.
I reviewed the NDK Users Guide and verified that I am linking to the minimal NDK library builds. According to the mbed TLS web site (which according to the NDK Users Guide is used by the SDK for TLS comms), the memory footprint for this library should be small (between 25k - 100k) so why does the code footprint increase by almost 4x when I switch to the secure stack library? Is there any way to reduce the code footprint size?
Here are the versions of the products I am using:
CCS version 9.2.0.00013
SimpleLink SDK v3.20.0.10
Part Number: TPS659037
HI TI team
What's the difference TPS6590375ZWSR TPS6590377ZWSR TPS6590378ZWSR ？Can they replace each other?
Tps6590375zwsr has been EOL. Which device can we replace?
AM572X_INDUSTRIAL_EVM_3M0001_DSN_REV1_3B.DSN reference design use Tps6590375zwsr
Thanks

Hi!
For a long time I have been struggling with the problem of launching two serially connected evaluation sets www.ti.com/.../TIDM-DELFINO-ETHERCAT. I am trying to run my own application based on the example TMDSECATCNCD379D_EtherCAT_Solution_Ref as a Master I am using Beckhoff IPC6015 and TwinCAT. After setting up synchronization with Distributed Clocks and loading the configuration, an error appears: 'SAFEOP to OP' failed! Error: 'check device state for OP'. AL Status '0x0004' read and '0x0008' expected.
In CCS Expression View I am looking at variables that show that there is a synchronization error.
I'am using SSC Tool version 5.12 to generate Slave Stack Code
I don't know where to look for the reason. Without DC Synchronization it works.
Dear sir,
I want to drive an Ultrasonic Transducer of say 50 watts at 40Khz frequency for ultrasonic cleaning method on single phase. Do we have any design ?

Hello,
We built a collection of libraries that are included across many different projects. We have an encountered an issue that is hard to reproduce but wanted to bring your attention to it and see if this is a known bug.
We have seen this issue since CCS 7 but are now using CCS 9.0.1.0004 on Windows 10 systems. We have libraries that have 16 include paths. If we add an additional include path and hit "apply and close" sometimes the include path will not persistent when we examine it again. To ensure the include path sticks we always have to verify that the include path list.
I didn't see any commentary on the forums but wanted to check if this is something that has been seen?

Part Number: AM5716
Hi,
We would like in our project to implement the OPUS codec on our custom board based on AM5716.
I see that TI has pre-built library files for codecs available at (http://software-dl.ti.com/dsps/dsps_public_sw/codecs/C6X_Speech/2_00_000/index_FDS.html ).
I also understand that TI is "out of the codec business" for now.
However, I am wondering if there exist any help files or user guide documents regarding how to implement and use the pre-built library files? Or some example projects to look at?
Appreciate any help.
Thanks for your continuous support,
Anders.
Part Number: LM5069
Hi Guys
Our customer is using our LM5069 for hot swap. typical 48V. MAX 54V; 50A current load. and they have a 5000uF cap load. So when start up, there will be a inrush current. so need to limit the current. we will set the current limitation and TIMER Cap. here do you have proper mosfet suggestion? how to select this mosfet?
Thanks

Hello!
i'm a CC3200 beginner. Maybe somebody could help me.
My tools:
CCS 9.2, TI-RTOS, SDK3.30.01.02, Kit: CC3220MODASF
My goal:
LIN interface
Problem:
the SYNC Break field causes me problems.
I dont know how i can realize this with the SDK
i want to switch the UART1_TX PIN07 between:
1) SYNC modus: PIN07 is GPIO output
2) UART modus: PIN07 is UART_TX ..... OK is working
My solution:
PinModeSet(61, 0); // GPIO MODE
PinModeSet(61, 5); // UART MODE
working not well.
Somebody could help me?
thanks and best regards

Part Number: TPA3137D2
Hi,
Does connecting PLIMIT directly to GVDD give the maximum output power on the TPA3137D2?
It is stated so in the TPA3138D2 datasheet, but not on the TPA3137D2 datasheet.
Thanks.
Part Number: CSD18532KCS
Hello team,
do we have any alternative to the is FDBL86062_F085?
I saw we do have some 100V devices but none of them seems to have a low Rdson.
Could you please let me know any alternative? It would be used in conjunction with our LM5050-Q1 for a brushless application.
Thank you and best regards,
Adrian
Part Number: TMS320F28069M
We wish to perform unattended Device Firmware Upgrade over CAN bus (Emulator not connected).
We have been referring to SPRACN1.
http://www.ti.com/lit/an/spracn1/spracn1.pdf
"This application report describes a software controlled firmware update process on C2000 devices using
existing boot modes without the need to manually select boot mode."
The only way to get into the CAN boot-loader (on our device) seems to be via "Get mode".
Based on 2 GPIO Pins and 2 OTP Locations.
Question: once DFU is complete and we invoke a reset, how do we boot to FLASH and not re-enter the CAN bootloader?
