Part Number:LMG3410

Hi,

we would like to control the slew rate of the LMG3410 through a digital potentiometer.

In the Data Sheet it is not that clear, is there a current mirror connected to Pin RDRV?

Which voltage can i expect at that Pin?

Kind regards Marcel

Hello,

I have been trying to run the mmw demo on the AWR1642 BOOST. I made some changes of this demo, which include the modification of  the function 'MmwDemo_interFrameProcessing' and the uasge of a free EDMA channel to transfer data. There is no error when I rebuilt the demo and load it to the EVM. However, when I run this demo, the CCS aborts and writes the following errors:

As the second error says, it is the assertion failure in line 1698 in "mss_main.c". I thought maybe it is the 'MMWDEMO_BSS_CPUFAULT_EVT' status that causes the assertion failure.

But I donn't know how to understand the BSS_CPUFAULT and what condition could trigger this event? Could you help me?

Also, I know you and your team members are very experienced in debugging  AWR1642 demo. So could you give me some advice on how to solve this problem?

. Thank you!

Part Number:TCA6424A

Hello,

I was looking through the datasheet, and it doesn't specify what the rise and fall time of the device's port pins are with a change to output?

Could you specify what this is and what load it was tested with?

Thank you,

Louie

I am trying to build a car with obstruction detection using analog output proximity sensors. The problem is whenever I integrate the PWM module for moving the vehicle and the proximity sensors, the PWM does not update (I measured the with an oscilloscope). The weird thing is that whenever I step into the program line by line, the PWM updates but if irun the program it doesnt update.

Below is the code I currently have.

Part Number:LAUNCHXL-F28379D

I am using Simulink Embedded Coder to program my microcontroller, I am trying to generate a 25kHz sine wave for my speaker. 

I am monitoring the signal by connecting an oscilloscope to GPIO pin 70.

When the frequency is 25kHz there is no signal. The result is as follows: 

Then I tested the system by reducing the frequency to 250Hz. The result is as follows: 

Then I changed the step size from "auto" to 1/(5e5) and the result is as follows:

But as I said this signal disappears in about 100 seconds. In the video below, I captured this weird behaviour.

(Please visit the site to view this video)

Why is this signal not continuous and it disappears after a while? Why does i not appear like a proper sine wave when the fixed step size is configured as "auto"?

Finally I will share some screenshots to help with the troubleshooting.

This is my code. First I generate a sine wave with Amplitude 1 and Frequency 250Hz. Then I amplify it by 2047 times and shift it up by 2047 in order to create a sine wave in the range of 0-2^12..

This is the configuration parameters window where I changed the Fixed-step size. Note the solver type is "Fixed-step" and Solver Type is "discrete (no continuous states)".

Part Number:CC2540

Hi Team,

I have been searching e2e posts for corrupt UART data; most posts seem to address Tx side while my issue is with Rx side on CC2540 (external Tx side pretty well tested and flushed out).  

I found this e2e post which essentially suggests that if you are using UART w/ DMA, you should ensure the HCI_EXT_ClkDivOnHaltCmd()function is not called; even though not using DMA I tried this but no luck.  

two questions:

1) Any idea what can be causing me to receive garbage data in ~5% of my messages?

2) when it comes to commenting out HCI_EXT_ClkDivOnHaltCmd() function, I see the comments suggests MCU is halted when network processor is active; is this true and could this be contrinuting to the issue I am seeing?

// Enable clock divide on halt

// This reduces active current while radio is active and CC254x MCU

// is halted

//  HCI_EXT_ClkDivOnHaltCmd( HCI_EXT_ENABLE_CLK_DIVIDE_ON_HALT );

Part Number:LAUNCHXL-CC1310

Hi.
I am trying to set up a sniffer fw on LAUNCHXL-CC1310 to sniff sub1ghz packets coming from CC1350 sensortag.
I used C:/ti/simplelink_cc13x0_sdk_1_30_00_06/tools/ti154stack/TiWsPc2/sniffer_fw/bin/sniffer_fw_gfsk_50kbps_868_915.hex with Flash Programmer to flash the launchxl, and it flashed successfully.
When the device is turned on, the green led is blinking and I can see in UART the string "TI Packet Sniffer ver.1.0.0" printed every second.

I installed smartRF packet-sniffer 2 from TI but when I turn it on, it cannot find any devices, also when I press "Search for new Devices".

Can you please help, How do I set up the sniffer?

I am trying to get 3 cc264PBA v1.1 wireless module to transmit, as slaves, values from an IMU to a master LAUNCHXL-CC2640R2 that connects to the CPU where it is used to register movement, and I keep receiving target errors. I am here to inquire about any documentation that could prove helpful or any other help that could be offered.

Part Number:LMP91000

Dear Community,     

I am trying to configuration the lmp91000 for work with the sensors O2-M2 and ETO-A1 both of Alphasense.

The settings that I used for the sensor O2-M2 are as follows:

LMP91000_TIA_GAIN_350K | LMP91000_RLOAD_100OHM,
LMP91000_REF_SOURCE_INT | LMP91000_INT_Z_50PCT | LMP91000_BIAS_SIGN_POS | LMP91000_BIAS_0PCT,
LMP91000_FET_SHORT_DISABLED | LMP91000_OP_MODE_AMPEROMETRIC  

And the settings that I used for the sensor ETO-A1 are as follows:

LMP91000_TIA_GAIN_350K | LMP91000_RLOAD_33OHM,
LMP91000_REF_SOURCE_INT | LMP91000_INT_Z_50PCT | LMP91000_BIAS_SIGN_POS | LMP91000_BIAS_6PCT,
LMP91000_FET_SHORT_DISABLED | LMP91000_OP_MODE_AMPEROMETRIC 

My problems are the following:
I'm not sure the values for TIA_GAIN, REF_SOURCE, INT_Z and FET_SHORT, ¿how I can know the values for these parameters?

Part Number:TMS320F28377S

Hello,

I'm confused by TMS320F28377S's internal voltage regulator. It looks like it is not supported anymore. But when I enable it by pulling down VREFENZ pin, the VDD pin gives me 1.2V. Is there still a voltage regulator inside F28377s? If so, what is the problem to use this voltage regulator? Thanks!

I have a CCS3220SF-LAUNCHXL. How can I burn using CCStudio 8 without Uniflash when I switch SOP jumper to the middle set of pins (position = 1) ?

Part Number:TPS92518

Hi

I would like to double confirmed about the pwm jumper name.

On schematic the PWM are controlled with J6 and J13.

But on the setting description is J13 and J15, is it a typo?

Thank you.

Hi, dear sirs:

We need to read the location of the sensor tag, so we are using the barometer to find the altitud of the tag, but the data looks out of range, is there a procedure to calibrate it?

Hey Everyone!

I'm stuck trying to compute the fractional bits of the TBPRDHR. I'm not sure how to realize this inside the code. Can anyone help?

Thanks,

Is there a workaround to set the Phy Address to 19h ?

Datasheet shows only phy_addrs[3..0] to be configurable with phy_addrs[4] set to "0"

thanks

Part Number:TMS320VC5421

What tools options do we have for working with the TMS320VC5421?

I have not been able to find an emulator or any CCS support. How far into the newer CCS versions did we support the VC5421, or C54x in general?

Thanks and regards,

Hi,

We have an old DMD device (0.7 XGA DDR DMD) which comes with the board, Discovery 1100. I tried to install the drivers on Win 10 and the attempt is failed, however, the software seems working, other supporting software are not communicating with the device.

I think our current DMD device is sufficiently good for our research purposes, it is just the board that encounters problem with the new operating system and does not function.

I wonder if it is possible to update the board and supporting software and mount the old DMD on the new board? If we do so, will it work with new operating systems (like Win 10 or 7)?

If yes, please provide me the links/information of the person/company whom I can contact with to replace our board, also we would like to figure out about the prices in this case.

In addition, it would be nice to know whether there would be some discount options in case of returning the whole old device (including the DMD) to the company and order a new board with newer DMD chip-sets?

thanks,
