Hi,

   I can see TPS73633-Q1 part in TPS736-Q1 Datasheet, I have TPS73633-Q1 (Fixed 3.3V output ) part, but  I did not see  TPS73633-Q1 order information.

Do you check  TPS73633-Q1 RTM? can we provide this part  TPS73633-Q1? Thanks!

TCA9534A: Interrupt

Part Number:TCA9534A

Hi team,

My customer wants to know when /INT is reset.

In the datasheet page.17 8.3.2 Interrupt Output (INT) section, there is a description that
"Resetting the interrupt circuit is achieved when data on the port is changed to the original
setting or data is read from the port that generated the interrupt".

We understood as in the following time chart, is it correct?  please let me know.

Best regards,
Fumio Nakano

TPS7B63-Q1: Side effects for R_ROSC 2k...10kOhm as watchdog

Part Number:TPS7B63-Q1

Hi all,

my customer wants to use the watchdog function of TPS7B6333-Q1 with the following parameters (see, datasheet p. 15):

FSEL = Low

R_ROSC = 2 k .. 10 kOhm (twd = 1 .. 5 ms), lower value is better from customer’s systems perspective.

 

In the overview / specification R_ROSC is used as a parameter (not limited) with values >= 20 kOhm

 

Does/What kind of side effect(s) does the customer introduce if they choose R_ROSC in the range 2k .. 10 kOhm?

 

What disadvantages besides of higher power dissipation will occur?

Thanks,

Konrad

TMDSDOCK28379D: TMDSDOCK28379D - The JTAG DR Integrity scan-test has failed - No software problem

Part Number:TMDSDOCK28379D

Hello,

I receive "The JTAG DR Integrity scan-test has failed" warning upon trying a test connection. I cannot debug and load the program as well, i did not record the error message.

While searching the previous answers for related problems, I happened to find another control card, when I installed in on the docking station everything works as expected. Which eliminates the possibility of software related errors, I suppose.

The point is: the device was not connected to a converter, I was following the "multi-day workshop". I returned from lunch and saw the card malfunctioning. Electrical damage to the control card is very unlikely as it just sits on the table. 

Does this situation show that the previous control card is physically damaged? It is kind of bad loosing a control card like this. 

Any advice will be appreciated.

Thank you in advance

DK-TM4C129X: Flashing TFT display in raster mode

Part Number:DK-TM4C129X

The raster mode is set. DMA is on. Ping-Pong is not used.
If we change the picture pixel by pixel, then everything is fine, but if we update it with a block, for example, symbol 44 font, the display blinks. There is an interrupt DMA FIFO Underflow. Apparently interrupted LCD DMA
At what point can we write to the buffer to avoid interrupting the DMA?

Hello,

The S pin of TCAN1051 is suggested connected to GND via a pulldown resistor when unused in the datasheet p.27.

But is the resistor really necessary? Can't it be connected directly to GND?

Thanks.

Compiler/TMS320C6678: guide to reduce build time of C6000 C compiler

Part Number:TMS320C6678

Tool/software: TI C/C++ Compiler

Dear Team,

My customer is complaining on the build time of C6x compiler and requested to provide coding guide to avoid long build time.

Their compiler version is very old - v7.3.0. Do you think this compile time can be shorter when they upgrade compiler version with latest one?

Actually, I'm afraid they can not upgrade compiler version as they have used it very long time and their RTOS version and other SW packages are also old.

In C6000 compiler v7.3.0, Could you please provide a guide to reduce this compile time?

- Is there compiler option to reduce build time with minimal impact on performance?

- Is there coding guide to reduce build time? like avoid if, for, and so on.

TPL5110EVM: - question about mcu re-initialization after start up

Part Number:TPL5110EVM

Hi,

Firstly, i am reading documentation for TPL5110EVM from following link "http://www.ti.com/product/TPL5110/technicaldocuments"

I understand the basic concept that, TPL5110EVM active power consumption is significantly lower than microcontroller sleep state consumption. I got that.

But i have following questions:

Q1. TPL5110EVM will totally cut off power to mcu during "OFF Time" right. Thats mean, when it back to "ON Time" again, mcu will behave like, just power on and will have to re-initialize all of its routine again, isn't it just consuming more power rather than wake up from sleep state?

 

Q2. Is there  any documentation/experiment that is conducted for Q1 related scenarios using mcu such as CC2541 or CC2641 to verify that TPL5100EVM is saving power even though mcu has to redo the initialization?

Thank you.

MSP-FET: How much is MSP-FET Emulation Tool "sensitive electronic"?

March 28, 2018, 1:11 am

Part Number:MSP-FET

Good Morning everybody!

Today I'm here to highlight an annoying issue with MSP-FET Flash Emulation Tool.

What I noticed is this: if in close proximity of my FET there is, for example, a power strip with on/off switch button and someone else is using it (switching on or off) while I'm doing the debug of my code, the program suddenly gets stuck. This is the same behaviour as if you have some relays on the board on wich you are programming: if I'm in debug mode, step by step, and at some point the relay is triggered, the debug gets stuck and I have to:

--> stop the debug mode

--> disconnect the emulator from both the PC and the board

--> re-connect everything and actually re-start with my debug section.

How is it possible that the emulator is so sensitive?

Is there a way to avoid this annoying behaviour?

I really would appreciate any advice and piece of help.

Kind Regards,

Maria Angela
