Part Number:LM5576
I've been trying to get a -24V output out of the following circuit, but the voltage readings I've been getting are below 0.3V. The input voltage comes from a battery with a maximum voltage of 29.6V and a minimum voltage of 24V.

CCS/CC2650: CCS/CC2650
Part Number:CC2650
Tool/software: Code Composer Studio
Hello,
I've been trying to upload code to a custom board I've built using the CC2650 (32 pin, model RHBT) - the schematic is based off of TI's sensor tag schematic. I've managed to upload example code (PWM example from the TI-RTOS examples) successfully to the 2650 SensorTag kit and the 2650 LaunchPad using CCS, but when I try and upload it to my board using the the JTAG port from the Debugger DevPack, I'm getting this issue
Error connecting to the target:
(Error -242 @ 0x0)
A router subpath could not be accessed.
The board configuration file is probably incorrect.
(Emulation package 8.1.0.00005)
(Please visit the site to view this file)
Which worries me, because I get the same error when the debugger is not plugged into anything at all. I've triple checked my JTAG connections and the power supply traces to the 2650, which all appear to be working fine. I've tried uploading example code from the CC2650_5XD example set since the 2650 model on the 5xd kit is also 32 pin, so I figured the pin mapping would be the same - perhaps this wasn't the best idea.
Am I missing something obvious? Should I not be using the DevPack for this? Or does anyone have any suggestions on how to get past this? Any ideas are appreciated.
Thanks!

BQ76940EVM: Unable to detect the BQ76940 chip on the I2C bus
Part Number:BQ76940EVM
Hi,
We are trying to talk to the bq76940 chip on the bq76940evm board. However, using an arduino to check on the i2c bus does not detect the particular 0x08 or 0x18 address for the BQ chip. I've ensured that the cell simulator is switched on with the orange led lit. The jumpers for SDA and SCL pull up are also plugged in.
The boot pin button enables the bq chip(seen by detecting a 2.5v on the pull up line)

CC2650EM-4XD-RD: XBAL object failed - Forced Mass Erase Doesnt Work
Part Number:CC2650EM-4XD-RD
Hello,
I have about 30 custom boards that use the CC26504XS chip. I have previously programmed these boards using Flash Programmer 2 through 2-pin JTAG with either a SmartRF06 or LaunchPad board. No issues. However, now I keep getting "XBAL object failed" on a majority of the boards when programming. The ccfg file for the project was never changed so I'm not sure why it is saying that the board is locked. I've tried using Forced Mass Erase but it will either 1) have "XBAL object Failed" occur or 2) "Erases"(says erase was successful...) and then still can't program afterwards ("XBAL object failed" still). I have uninstalled and reinstalled Flash Programmer 2 and have also tried a different computer but the issue still occurs. Any help is appreciated as this is hindering my research.
Environment:
- BLESDK 2.2.0
- CCS 7.4.0
- tirtos 2.20.01.08
- xdc 3.32.00.06
- Flash Programmer 1.8.0
Thanks,

CC2642R: Simple_Peripheral Example Project Issues
Part Number:CC2642R
Open CCS 9.0.1.00004, import project simple_peripheral_app_CC26X2R1_LAUNCHXL_tirtos_ccs into the workspace from simplelink_cc13x2_26x2_sdk_3_10_00_53 SDK, "Build Project"...
>> Compilation failure Build of libraries failed. subdir_rules.mk:12: recipe for target 'build-295672945-inproc' failed "C:/ti/simplelink_cc13x2_26x2_sdk_3_10_00_53/source/ti/devices/DeviceFamily.h", line 173: fatal error: #error directive: "DeviceFamily_XYZ undefined.

Compilation terminated.
Why doesn't the example work right out of the box?
Also, the reason I was loading this project in the first place was to see the changes that version 3.10.00.53 of the SDK made from 2.30.00.34 to simple_peripheral.c/h and simple_gatt_profile.c/h, as our project is based off those as an example. Except I can't find simple_gatt_profile.c/h anymore, and neither can CCS: trying to F3 to "Open Declaration" of
SimpleProfile_AddService(GATT_ALL_SERVICES); // Simple GATT Profile
gives an error:
Could not find symbol 'SimpleProfile_AddService' in index
What happened to it? I know the stack is in ROM now, but surely the source file for the example service with all the example characteristic declarations isn't part of that and is still around for modification, right?

TLV5638M: EXPORT License to ship to China
Part Number:TLV5638M
Hello,
I have a client who would like us to procure some TLV5638MJGB/883 for them. Every distributor I looked at said that there may be export restrictions on this part. The part is classified as either EAR 3A001.a.2.c, or ECCN 3A001.a.2.c(never sure which is correct!). My question is simple for the right person. Can I export this part (I am in the United States) to my client in China? They say that the application is some kind of automobile testing product.
OH!!, I guess I should also ask how to ship to China. I think think the Commerce Control List is telling me that I need a license to export it. Can you confirm this AND tell me how to get licensed to do this? This is all so very confusing!
Please help me to answer this question.
Thank you very much.

TIDA-01168: Details on Top Side Interface Material

Hi Team,
My customer would like to know more details on the interface material between the bus bar and the top side of the PCB on page 10 of TIDA-01168?
More specifically, is the bus bar in direct contact with the copper planes (board top side) or is there an interface material to fill in the air gaps (if any)?
I see that the materials and detailed description are included for the bottom side, but want to understand if it’s the same for the top side.

RTOS/LAUNCHXL-CC2650: connection issue

Tool/software: TI-RTOS
Hello,
I am trying to use mailbox protocol along with simple_peripheral_observer from https://github.com/ti-simplelink/ble_examples/tree/ble_examples-2.2,
I am using BLE scanner app, to read the messages, and it is working as required when I am working on cc2650 launchpad, and it scans the bluetooth devices well.
But, when I am using the same source code on a sensor that has cc2650 chip - connected to 2650 launchpad debugger, I see an issue with the connection.
I can see the advertisement on BLE scanner app, and I can connect to it as well, but when I am trying to read messages, it disconnects immediately.
Can someone let me know what might be the issue?

CC2564C: BT Classic: How to get a feedback of the BER/Quality of the A2DP link we are transmitting?
Part Number:CC2564C
Hi TI,
We are using CC2564C as A2DP Source in Bluetooth Classic with TI assisted A2DP (A3DP) mode.
Most of the traffic is from TI CC2564C to the headphones (Sink).
Via the Bluetooth baseband packets the Sink sends back ACK/NACK to the Source (TI CC2564C).
Please may you suggest way(s) for us to get information about the ACK/NACK that TI CC2564C receives from the Sink?
Based on any metric you can provide us to judge the quality of our transmission we wish to implement some specific behaviors on our system.
Thank you in advance for any suggestion,

FDC2214EVM: I2C controller for FDC2214
Part Number:FDC2214EVM
Hi,
I am going to use LabVIEW to control the FDC2214, however, TI does not have LabVIEW support for FDC2214, alternatively, I am going to use National Instruments(NI) I2C module NI USB-8452.
The NI USB-8452 is a USB 2.0 high-speed, high-power device with a maximum theoretical transfer rate of 480 Mb/s. Using a high-speed FPGA-based architecture, the NI USB-8452 supports SPI data acquisition up to 50 MHz and I2C communication up to 3.3 MHz. The programmable reference voltage covers logic families from 1.2 V to 3.3 V, which makes the NI USB-8452 versatile for most SPI/I2C tests and verifications.http://www.ni.com/pdf/manuals/371746d.pdf
The FDC2214 has a frequency requirement in both master clock (2-40MHz) and excitation (0.01-10Mhz). The up to 3.3Mhz frequency limit of the NI USB-8452 is at the very low end of the FDC2214.
I would like to know if the NI USB-8452 can be used to control the FDC2214. The benefit of using a NI I2C controller is that NI provide many VIs and descriptions on how to use the VIs, which make it easier for me to program the controller according to my application.
