Part Number:TMS320F28069M

Tool/software: Code Composer Studio

I am using this example for testing ADCINA5. This code works accurately on DRV8301-F28069 kit. In my custom board ,
 I tested this code and it works fine in debug mode but in RUN mode I get 1 value of temp and then every register gets resets to 0 and ADCRESULT also goes to 0

TPS54620: COMP pin voltage

Part Number:TPS54620

Hi,

Could you tell me about the value of COMP pin voltage (Vcomp)?
The voltage at the COMP pin should be clamped.
What is the clamp voltage? And what is the maximum value?
Our customer wants to know in order to grasp the impact of changing to a lower rated voltage capacitor.

Best regards,

TMS320F28069: QEP Index Edge to QuadA/B edge specification

Part Number:TMS320F28069

I am referencing Figure 7-10 in SPRUH18G.   The figure shows a separation between the rising edge of QI and the falling edge of QB.  As these edges get closer together, at some point I assume the behavior (value in QPOSILAT) no longer becomes predictable.   This would be the result of setup and sample times in registers and io buffers.  We are hoping to provide a specification for a minimum separation between the QI and QA/B such that the behavior (capture value) is only predictable when this minimum separation time is met.   (10ns for example).

CDCE62005: LVPECL output level specifications

May 14, 2019, 9:00 am
$

0

Part Number:CDCE62005

For the LVPECL output, VOH maximum is spec’d as Vcc-0.88, or 2.42V at Vcc=3.3V. VOL minimum is  given as VCC-2.02, or 1.28V at Vcc=3.3V. This gives up to 1.14 V swing on each LVPECL output, or up to 2.28 V differential swing. Even if we assume nominal levels for VOH and VOL as midway between the MIN and MAX specs, we get 1.66 V differential swing.

So, what is meant by the specification: |VOD| Differential output voltage? It is specified to be between 610 and 970 mV. Is this intended as the differential peak-peak output swing? If so, it seems at odds with the value that we would compute from the combined VOH and VOL values for the individual outputs.

MMWAVEICBOOST: IWR6843 ISK, no console response from mmWave Demo Visualizer

Part Number:MMWAVEICBOOST

system details:

OS: Windows 10

SDK version: 3.1

silicon revision: see image

version of compiler and code composer studio: N/A

issue:

I was able to successfully flash the xwr68xx_mmw_demo.bin file located in the mmwave_sdk_03_01_01_02 folder and connect to the device in the demo visualizer (shows serial ports connected and "waiting for data ..."), but nothing happens when "send config to mmwave device" is pressed.

details:

- power was removed from the device and NRST button was pressed after flashing

- SOP2 was opened

- NERR is not lit

- NRST_FT LED is lit while the NRST button is not pressed, from my understanding of the user guide this is not correct. (user guide says "if the LED is glowing, the device is in reset state")

- if the FTDI micro-usb cable is plugged in the SOP indicator lights get much brighter and flash "randomly", eventually staying on and showing different SOP status lights than I would expect

- when connecting to the demo visualizer I've occasionally seen the message "Hardware Connected" rather than "waiting for data ..." and even more occasionally I've seen it say something like "Hardware Connected no security"

TAS2505-Q1: distortion issue

Part Number:TAS2505-Q1

Hello,

My customer has a distortion issue with TAS2505-Q1, Vdd=5V, Rspeaker=8ohm:

If taking 1.5KHz sin wave as the input, when

  • Set amplifier gain=6db, no distortion with sin wave(parallel with a big transformer>15H), but the volume is very low.
  • Set gain=12db, get below waveforms in speaker side (parallel with a big transformer>15H), the waveform has distortion
  • Set gain=32db, get pwm signal (serious distortion) in speaker side (parallel with a big transformer>15H)

I checked the TAS2505 power supply and SPKP/M waveforms, it operates normally, no undervoltage issue.

Here are the schematic and register setting. Thanks.

CC3220MODA: No silkscreen in designated area?

Datasheet says "No traces, vias, GND plane or silk screen should be located within this area" for the CC3220MODASF module (MON0063A, page 97). I totally understand that any metal including traces, GND planes and vias would affect antenna, but is it really true that we can't have any silkscreen in this designated area? I was thinking of putting our company logo in the area on the bottom side of our PCB while the CC3220MODASF module sits on the top side of the PCB.

Thank you.

Hi

In Uniflash, it is possible to configure http server certificate file and server private key like following.

(It is surrounded with by red square)

(Please visit the site to view this file)

If OTA tar file is created with Uniflash, is it possible to update this certificate file when OTA update?

Since this certificate file will expire in 3 years, it is necessary for customer's production to update by OTA image.

Part Number:CC1352P

Tool/software: TI-RTOS

Hello TI community,

I want to know if there is any reason I shouldn't set the values of the RTC sec and subsec using :

HWREG(AON_RTC_BASE + AON_RTC_O_SEC) = u32_RTC_SavedSec;
HWREG(AON_RTC_BASE + AON_RTC_O_SUBSEC) = u32_RTC_SavedSubSec;

after a BIOS_start(), when the OS is running ?

Is there any real time risk doing so ?

I would like to restore the value of the RTC in case of a reset. (which seems to set the RTC time to 0, the BIOS_start seems to reset the value to 0 as well, am I right ?)

I intend to do it as the first thing I do in my application.

Thnaks for your advice !

Hello, 

I would like to drive a GaN Fet with this controller for a DC/DC from 24V to 80V.

However the gate voltage is too high: I need it at 5V max; is it possible to do this, e.g. forcing VCC at 5V with Vin not connected?

Or can I use a separate rail for Vin at 6V, while the input voltage for the boos will be at 24V?

Hello TI;

 I have tried to edit my Projects in Webench and now I am getting an error that says that the "Design cannot be created with this device".

I am getting this error by simply trying to change the Vout of one regulator, for example from 6.9V to 7.05V , curiously, If I change it from 6.9V to 10V it works (Vin is set from 14V to 16V)

I tried to change it several times and I still get the error I even tried a new design and got the same error.

*It is important to notice that previously I never had this error.

What is happening?

 

Regards;

Luis
