CC2650: How to set/control the network joining/discovery duration for end device.
Part Number:CC2650
Hello,
If Hold auto start flag is disabled.
As soon as we power on the device it will start looking for network and sends beacon requests.It will try looking for network until it joins any network.
As per my requirement the device should send beacon request for 2 minutes.within 2 minutes if it does not join any network, I want the device to stop sending beacon request.

TPS92314: about VREF
Part Number:TPS92314
Hello
I am sorry to bother you again.
My customer chosen TPS92314, but has questions about Vref again to fix their
final product's design goal.
Q1
Risns result from TPS92314 Calculation tools Rev 1.1 for non-isolated work-sheet
I think if IOUT were 100mA, RISNS should be 1.4ohm,
but calc result is 1.47ohm.
Is it a bug?
The work sheet of 'isolated' page seems to be no problem.
Wold you please confirm?
Q2
How does Vref made in the BIAS& VREF block of data sheet p7,Fig13 ?
TPS92314 has internal reference voltage in the BIAS&VREF block as
1.21(MIN)/1.24V(TYP)/1.3V(MAX) which is used for VDLY as described
EC table in page4.
My (Customer's ) guess is Vref = 0.14V on data sheet p15 eq(2) is divided
from internal reference voltage 1.24V ( VDLY ),
...Is it correct?
Best Regards

AM5716: Pin compatibility with AM5746
Part Number:AM5716
Hi,
I am going to check the compatibility of pin between AM5716 and AM5746.
First of all, I will design a unit by using 5716 and later after CAN FD function would be used widly, I will use the AM5746 for CAN FD.
if th pins of the two chipsets are compatible each orther, transforming 5716 to AM5746 is possible easily..
so I want to confirm it ...

SN65LV1224B: Package pinout information and mechanical package information
Part Number:SN65LV1224B
Hi team,
My customer is going to replace DS92LV1212 with SN65LV1224B.
But we can't find the package pinout information (ex. ROUT0 to TOUT9 arrangement) and
the mechanical package information(ex. LAND PATTERN and SOLDER PASTE etc.) in the datasheet.
There is SN65LV1224B in similar varieties of SN65LV1224B-EB.
Can the customer refer to those of SN65LV1224B-EB.
Please let me know.

TMS570LS0714: SCI via DMA message overwritten by regular sciSend function
Part Number:TMS570LS0714
I have two ways of sending UART data from MCU to PC: one uses the standard TI SCI driver (sciSend function), and another one uses DMA. However, if I send a message using the DMA function and shortly after another message using the standard sciSend, the DMA UART message never appears. Is there a way I can send messages using DMA and sciSend and ensure that both types of writes will successfully complete and not overlap or cancel each other?

SND9039 Cherry Trail power up problem
Hi,
My customer have problem during power up.
This happens during fast turning on and off the PMIC.
condition: connect and disconnect the 5V adapter to the PMIC will cause problem for power up.
Originally, power up automatically after adapter is connected, but under this operation, it will need to press power bottom to start up.
What i want to know is why this happens and how to solve.
Now i am asking customer to check if we are in to PMIC off before the adapter is connect again and see where does the sequence stop during cold boot.
Please help if you have further comments.
thank you.

CC1310: Why result.panDescriptor is always NULL in TI-15.4 sensor example?
Part Number:CC1310
Hi,
My customer is using TI-15.4 non-beacon mode, and he wants to access the pan descriptor list after the scan.
I have done some test with sensor example, and found that no matter the ApiMac_attribute_autoRequest setting is TRUE or FALSE, the MAC will call Beacon Notify Indication Callback, and in processScanCnf(), the pCnf->resultListSize is always 0 and pCnf->result.pPanDescriptor is always NULL.
Please help to suggest how to store panDescriptor into macCbackEvent_t *pMsg and access stored PAN descriptors in it.
Thanks!

UCD3138: Double Zero Configuration Principle in Digital PID Coefficient Based on UCD3138
Part Number:UCD3138
Hello
I am currently studying your UCD3138-based full-bridge hard-switch development board. I am learning how to set the PID coefficient.
I read your application note "UCD3138 Digital ControllerControl Theory" on page 30 to learn how to configure the poles of the PID.The manual tells me that the two zeros are configured: To boost the phase by 180o, a 2 pole 2 zero compensator is needed and should be located at 1/10 of fc.
In the Fusion Design Offline software, I opened the bode simulation case of the UCD3138 full-bridge hard switch. As shown below:
The cross-over frequency of the system open-loop transfer function is approximately 4.7 kHz.
If the recommendations of the UCD3138 Digital Controller Control Theory are followed, the two zeros should be configured at 470 Hz, however, in practice, the two zeros are configured at approximately 8.1 kHz.
Why is this? What is the zero-point configuration principle of this full-bridge case?

Linux/TDA2PXEVM: Can't enable IPU1 when enable IPU2 to Process ISS&DSS
Part Number:TDA2PXEVM
Tool/software: Linux
Hello:
we will take the IPU2 to process camera capture and image processing, if run other task like APA control algorithm we will suffer the time critical issue of the camera capture,
and the follow is that we want to deploy our task on different IPU
- AutoSAR will run IPU1_0
- Auto-Parking algorithm will run IPU1_1
- Camera capture and process and display on IPU2(SMP)
And now, the VisionSDK has limited to enable the IPU1.
Any suggestion?
Thanks.
