Dear TI Engineers,
can you advice me to design the loop power for analog input with 12 channel total number, it' mean analog input connected with 4-20 mA 2 wire system with system power (2 wire analog input has 24v power).
what TI product you can suggest to me?
Part Number:LAUNCHXL-CC1352R1
Is the CC1352 capable of supporting a 128 byte transfer from one device to another (one way only, no ack needed) at a 1 KHz rate - basically about 1 Mbps data rate? But just as important at the overall data rate, the latency can't be too large, and of course, we'd like the jitter to be minimal.
The EasyLink samples I've tried all have large latencies and/or small buffers. Any pointers to sample code that works is appreciated. Of course, it'd have to be 2.4 GHz band to meet these data rates.
I've not seen anything in this forum or some of the others.
Thanks
Ed

Hi,
I am using tci6638k2k processor in our custom board. There are two ports: port 0 (interface eth0) is connected to a PHY and we are using link-interface as MAC-PHY (mode 1). This is working fine.
The other port (port 1) is connected to an FPGA device using SGMII. We are trying to use MAC_MAC_AUTONEG (mode 0) as link-interface for this port. However, this is not working when the FPGA device gets ready. (This port works fine under MAC_MAC_FORCED (mode 2) if FPGA device is already loaded.)
Wondering if this is a known/resolved issue ? (When was it resolved?)
Thanks,
Best Regards,
Nilesh
Part Number:TM4C129ENCZAD
Tool/software: Code Composer Studio
I installed Code Composer Studio 8 on macOS High Sierra 10.13.3, then used Resource Explorer. I was able to build one project and run successfully on the LaunchPad.
Now I am trying to build from a git clone of another project, and CCS8 is complaining:
Product 'tm4c' v2.1.3.156 is not currently installed and no compatible version is available. Please install this product or a compatible version.
I do not understand why I am seeing this error, since the product is already installed. I even tried uninstall and re-install, but no luck. I believe that I have eradicated the other developer's /Users/home path directory from the project files. As far as I know, the other project that builds is also using the TivaWare_C_Series-2.1.3.156 files.
I've scoured the project files looking for some bad path or other setting, but everything looks fine. The error message gives no details about where it is looking for the product. It's clearly installed, because when I run Resource Explorer and navigate to the "TM4C ARM Cortex-M4F MCU" item, it won't let me install without uninstalling first, telling me that Resource Explorer thinks the product is installed.
One difference is that the project that builds has its source inside my workspace. Meanwhile, the project that won't build has its source in another location, where git clone placed it. I use the "Import CCS Projects..." menu to add the source without copying it into the workspace (so that I can check changes back in to the git repository as I make improvements).
Is this an issue with CCS8? on macOS? I see other people with the same error message, but they're mixing Windows and macOS, and we're all macOS here.
Part Number:CC2650STK
Good day -
I'm using a cc2650 sensortag, along with the XDS110 debug probe (CC-DEVPACK-DEBUG). I'm developing a Contiki application and streaming output over the UART. I've observed over many instances that data appears to be corrupted. Examining the data, it appears that data existing in the FIFO is dropped in preference for newer data.
I've observed the problem at speeds of 115200, 230400, 460800, and 921600. Looking at contiki cpu/cc26xx-cc13xx/dev/cc26xx-uart.c, it is simply calling UARTCharPut.
Any advice would be appreciated.
Part Number:LMT70
Hello,
I am searching for a sensor probe making use of the LMT70 which employs a cable and attachment method similar to the following: https://www.omega.com/googlebase/product.html?pn=SA1-RTD-120&gclid=Cj0KCQjwtOLVBRCZARIsADPLtJ1BH5FEWLBiLXkZ6_cQOm0xvVHaGIFRwGWVibDSzo8mTyQ2_ERPfsYaAituEALw_wcB. A cable with a stainless steel overbraid option to reduce electrical noise and protect the lead wire from abrasion would be ideal. I'd like a cable with a lead length of ~6ft if possible, however that is not critical.
I've done many, many internet searches and have not been able to locate a cabled probe making use of the LMT70 yet. I am hoping someone can point me to a third-party supplier who has implemented this in a "stick-on" format which would be most conducive to the requirements of my monitoring project.
Thanks in advance for any information you can provide.

Part Number:DS125MB203
Dear TI Engineers:
We need a 1:2 switch or fan-out buffer using on 10G SFP transceiver.
We find 3 TI chips as candidates, DS125MB203, DS100MB203, DS100MB201.
Questions as below:
1) The speed on board can reach 10.3125Gbps. Considering performance/cost and supply, which device is recommended?
2) The PHY interface we use is SFI Interface, but no explicit description about SFI in datasheet's application. So We need confirm.
Thank you!
Part Number:LM358
Tool/software:TINA-TI or Spice Models
Hello,
Our customer trying evaluation LM358PW with TINA-TI.
They asked us which is correct model for them LM358 or LM358/101 and why the behavior is different from LM358 and LM358/101.
In TINA-TI, we can see both
" LM358 | Texas Instruments " and
" LM358/101 | Texas Instruments "
from "spice macro" tab -- "opamp" .
They and also I tried simulation by the customer's circuit, we had same results.
LM358 has very big change point i(Please visit the site to view this file)(Please visit the site to view this file)n phase-frequency performance, however LM358 has not.
I attached two .tsc file, please check them and please give us your advice.
Thanks and best regards,

Part Number:LM5018
Hi Team,
The datasheet shows efficiency of LM5018 is better than LM5019 under load current < 100mA.
Left: LM5018, Right: LM5019
On the other hand, Rdson is absolutely the same value between these devices.
Could you tell me what is caused efficiency difference?

Part Number:TMDSEVM3730
Hi, Sirs,
I have some questions about technical issue of USB transceiver on the TMDSEVM3730 board.
On the board schematic, USB_OTG have two ways connection to the PMIC and CPU
First way is USB_OTG data is going through using USB transceiver(Part No.=ISP1507BBS) to PMIC and CPU
Sencond way is USB_OTG data is just going through straight using connector(Part No=CON_PMC_30X2_M) to PMIC and CPU, but this way is disconnected in default
So what I did;
1. In the first way, I disconnected line of VBUS of USB transceiver(Part No.=ISP1507BBS) not to use part this USB transceiver any more.
2. In the sencond way, I put with all 0 ohm resistors(R214 ~ R225) on the connector(CON_PMC_30X2_M) to jump from USB_OTG through P15 to PMIC and CPU.
However, these works don't make to USB_OTG works. For debugging, I only can see the HSUSB clock wave, but there are nothing on any datas on HSUSB_DATA0 ~DATA7.
What should I see more detail to connect USB_OTG without using U36-ISP1507BBS part?

I'm trying to add FlashProgram() function call from driverlib to the example program that came with TIMAC SDK, which contains TI-RTOS 2.11. The compiled application ends up using the version of the FlashProgram() function that resides in the flash memory. Is there a way to use the version that resides in ROM?
Thanks!

On power up , it appears that the default Scan Reference is factory.
Is there a way to change this for a Scan Configuration, or where is this set.
Is there an NNO_* command that is used to set the option once the unit is powered up
I see how it is saved , but not how the option to use the "Previous" reference scan is selected.

Part Number:CC3220SF-LAUNCHXL
Hello,
I currently have a custom designed PCB based on the CC3220SF-LAUNCHXL files and I cannot get it to communicate the Uniflash. I have UART TX and RX along with the Reset connected and I made sure that the UART wires were properly connected. I also went down the following power pin checklist and found there to be no issues:
VIN_IO1 -> 3.3V
VIN_IO2 -> 3.3V
VIN_DCDC_DIG -> 3.3V
VIN_DCDC_PA -> 3.3V
VIN_DCDC_ANA -> 3.3V
DCDC_ANA_SW -> 1.9V
VDD_ANA1 -> 1.9V
LDO_IN1 -> 1.9V
LDO_IN2 -> 1.9V
DCDC_PA_OUT -> 0V
VDD_PA_IN -> 0V
DCDC_DIG_SW -> 1.2V
VDD_DIG1 -> 1.2V
VDD_DIG2 -> 1.2V
DCDC_ANA2_SW_P -> 1.6V
DCDC_ANA2_SW_N -> 1.6V
VDD_ANA2 -> 3.2V
VDD_RAN -> 1.2V
VDD_PLL -> 0V
I checked by 40 MHz oscillator as well and that yielded the same readings as the one on the launchpad (10MHz at each capacitor beside the crystal). I also followed the hardware design checklist when making my board and have not left out a single point on it. Lastly, when examining the UART with a logic analyzer, the reset pin is toggled and then there proceeds to be no communication between the XDS110 and my board. The UART Rx pin is pulled low while Uniflash is trying to connect and returns high after the connect attempt fails. I've had some issues with the SOP pins but included test points so I've simply pulled them to the values I want using these. I am currently trying the use UARTLOAD mode (SOP: 1 0 0). Included below is a screenshot of my Altium schematic, I can provide higher resolution or areas of detail upon request. Any help would be greatly appreciated because I'm not sure where else to be looking for an issue. Thank you!

Part Number:LAUNCHXL-CC1310
Hi,
I have 6lbr (Router mode) running with RaspPi + CC1310 launchpad (slipradio).
I got one more cc1310 launchpad into WSN. This end node is discovered and I am able to open web page to it.
I couldn't find it on IBM quickstart page.
I enabled prints in cc26xx-web-demo.bin and found from serial logs that it is stuck in MQTT connecting phase itself:
I don't see any packets in the output of tcpdump for port 1883 on RaspPi:
pi@raspberrypi:~ $ sudo tcpdump -i eth0 port 1883
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 262144 bytes
However, I see some packets in 6lbr.log with IP address matching the IBM quickstart messaging server (MQTT broker) with debug level increased to 8:
2018-03-27 1:04:46.797544: PACKET: SLIP: read: 73
2018-03-27 1:04:46.797676: DUMP: SLIP:
61dc1ccd abec63a4 13004b12 006e63a4
13004b12 007af000 000064ff 9b000000
00000000 00b8ac7c bd060063 04001e02
00040507 5b000000 64000000 00600200
809a8700 00020400 80
I tried reducing debug level also to understand if logging is leading to any timing issue. It didn't solve.
Not sure if IP64 setting in 6lbr also comes into picture for this behavior. But i have enabled IP64 as well.
Can I get some help on this ?
Is this because IBM quickstart broker IP is not reachable from my network ? OR
is the tcpdump indicating something is wrong in mqtt message communication in WSN itself ?
