CC1310: Does CC1310 communicate with passive UFH tag?

$
0
0

Part Number: CC1310

Hi

I'm planning to use CC1310 as UHF reader to communicate with passive UHF tag.

Q1:  Can CC1310 power supply to  passive UHF tag?

Q2:  How much power supply capability is there?

Q3:  Is it possible to use  CC1310 as UHF reader to communicate with passive UHF tag?

Q4:  Have you ever verify the communication between  CC1310 and  passive UHF tag?

Thanks and Best regards,

HaTa.


CCS: CCS 8.2 cause C/C++ Indexer rebuild full index

$
0
0

Tool/software: Code Composer Studio

[The issue]:

In CCS 8.2, when C file is modified and save. The C/C++ Indexer is triggered to rebuild FULL index. It takes tens of minutes to rebuild full index.

[Observation]:

After removed all TI CCS 8.2 components, the Eclipse C/C++ Indexer performs as expected and rebuild only modified file. It takes one second to index modified file.

[Project type]:

C/C++ Make file with existing code.

Based on the observation, it looks like some components in CCS always trigger full index rebuild, which is not expected and make CCS difficult to use.

Hi,

I have referred one of the post on forum to configure GPIO 0 as an EPWM and connect it to GPIO 2 via input cross bar. When I was trying to see epwm output on GPIO2, I am not getting any output ? Below are the lines of code, please suggest where I am doing mistake asap.

        EALLOW;
        GpioCtrlRegs.GPAGMUX1.bit.GPIO0 = 0;
        GpioCtrlRegs.GPAMUX1.bit.GPIO0 =  1;

I'm using CCSv8 (v8.3.0.00009) and XDS110 on a system with two TMS320F28375Ds.
"Load Program" of CPU1 and CPU2 of the first MCU in the daisy chain are succeeds.
However, in the second MCU, CPU1 succeeds, but CPU2 fails.


-- Error details --
Trouble Writing Register PC:

Device may be operating in low-power mode. Do you want to bring it out of this mode?
Chose 'Yes' to force the device to wake up and retry the operation.
Chose 'No' to retry the operation without waking the device.

I tried 'Yes' and 'No' but "Load Program" did not succeed.

Also, "Connect Target" to 2nd MCU may fail.

Please help me resolve these issues.

Part Number: DRV5033-Q1

Hi Sirs,

My customer is verifying the DRV5033 with the N52 magnet specifications below. Should we enter the parameters of Magnet Materials (N52) of Remanence (4000 Gauss) in the design tool at http://www.ti.com/product/DRV5033/toolssoftware? WHat is product line's recommended equipment setup to verify the flux?

We got different distance result as the pictures below (6.3mm vs 3.58mm). Customer confirmed that the 3.58mm does not work with actual experiment.



Thank you and Best regards,

CCS/LAUNCHXL-CC26X2R1: Simple peripheral & Btool

Part Number: LAUNCHXL-CC26X2R1

Tool/software: Code Composer Studio

Dear team

I'm using two CC2652R, one as host using the host_test example and  the other one as peripheral using the simple_peripheral example. The peripheral can't be discovered by the host using Btool, however, it can be discovered by using LightBlue (Iphone).

When i switch simple_peripheral to project_zero, everthing works fine. It can be normally discovered by the host using Btool.

So, is there anything I need to modify in the imple_peripheral example?

I tried several sdk versions: simplelink_cc13x2_26x2_sdk_2_40_00_81, simplelink_cc13x2_26x2_sdk_3_10_01_11, simplelink_cc13x2_26x2_sdk_3_20_00_68.

CCS version: 9.1.0.00010 

I tried to lower the advertising interval and scan again from BTool. But no luck.

Please help.

Hi

Could you please share the information for about Communication speed performance of Profinet and TCP communication via PRU.

For example, I'm interested in the following information:

 *Reference value of TCP communication speed via PRU

 *Estimated value or actual value for communication speed of Profinet via PRU

 *Expected extra latency by using Profinet and TCP at PRU at the same time

 

Please let me know any other information related to the communication speed.

DRV8711: OCP Failure

Part Number: DRV8711

Dear Sir,

I thought I'd like to separate FET and Rsense from DRV8711 in the circuit which is being used at present.
When I separated and made them move, a motor didn't revolve by OCP of DRV8711.
I don't know what does OCP judge, and whether Fault is being output.
What of a circuit is it necessary to improve for a motor to move?
I want you to tell me from a signal of which pin DRV8711 judges OCP.
OCPTH was changed to 1000mV and OCPDEG was set as 8 microseconds of maximum, but OCP Fault wasn't canceled.
Could someone help?

Best regards,

The cs pin of UCC2897A is sensing the current and it will cut the power off corresponding to 0.43V. But when the voltage goes below 0.43V, will it start again or will it latch? And what is the hiccup mode threshold? Over-all I want to know how this chip is controlling the current limit? 

WEBENCH® Tools: SSR relay

Tool/software: WEBENCH® Design Tools

Hello,

 i I am searching for AC load current switch with extremely fast ON and OFF time. could any one please suggest me which SSR relay is suitable for turn ON and turn OFF AC load current. i have written program for turn ON or turn OFF GPIO, then after  GPIO i am using PC817 which  switches on or off  SSR. I saw datasheet of PC817 it has turn on and turn off time of its has 4-20us delay time. is there any other faster than PC817?before i had electromechanical relay, after i turn on GPIO, relay is taking some time to connect or disconnect AC current. so i need SSR with exremely high speed. when i turn ON or turn OFF GPIO relay with turn ON or turn OFF at same time with almost no dalay too less delay in ns is acceptable
