CCS/CC3200: Is GUI Composer what I'm looking for?

Part Number:CC3200

Tool/software: Code Composer Studio

Hello,

I'm not sure if this is the right place to post this, but I would like to graph variables from my CC3200 in real time and maybe even control some of its outputs. I stumbled across GUI Composer and it seems like what I need. I went to the wiki and it says GUI Composer is not supported for CCS for v6.2 and directed my to the cloud based Gui Composer v2. I tried creating a project (Dashboard version) using this and selecting the CC3200 as my target device and USB as my method of communication and it wanted me to upload a "Target Executable". I have no idea what this is. All it said was this is a .out or .cpp.hex file. I would like to use this GUI composer with an existing CCS v6.2 project I have for the CC3200. Is there documentation on how to do this? I tried looking at all the wiki and help pages I could but the documentation seems lacking. Can anyone help?

Thanks,

John

Hello everyone!

I want to pair a smart phone and my product based on CC2541. Pair passcode is sent from WiFi or GPRS to each device. So I want to ask is this the OOB mode?

If I don't want the smart phone popup an input feild, just smart phone app handle the pair passcode  in the background, what need I do with the CC2541? Dose the smart phone need to be configged OOBFLAG supported?

Hi,

I have verify that the uart boot is successful on the evm board. (dra742)

but I failed when I tried to verify uart boot on our previous generation product. (dra744)



1st stage boot to MLO is working and the command line shows "u-boot-spl.bin file download completed.

then I try to  transmit u-boot.img to DUT through YMODEM, but it's can't working. XMODEM also.

Are there any hardware settings that need to be changed?

Hi~ Customer using TPS7A6333 and they want to trigger nRST when watch dog timer failure.

So they tied nRST and WD_FLT connected and added 10k ohm pull up, and it looks no problem.

But somebody asked there was some issue when connected two output so need double check if it has problem or not.

Hi all:

          As far as I know the am5728's  PROFIBUS and ETHERCAT-SLAVE functions can just work with RTOS system.

          Now we want to know whether these functions will be transplanted to the Processor Linux in the furture?

TM4C129ENCPDT: LMFlash programmer and ROM Boot loader

Part Number:TM4C129ENCPDT

Hello,

I am trying to use LM Flash Programmer build 1588 to program a TM4C129 empty board using UART, but I get error all the time.
When I use Auto Buad Enable, it think for a few seconds and then say "failed to syncronized..."
When I Disable Auto Buad it think for a few seconds and then say "failed to establish connection..."

Interesting to know that when I elect "TM4C129X Development" and JTAG/ICDI interface, it manage to program ok - no problems.
BUT, I want to use the UART interface with the factory ROM-Boot loader (not mine!)

I know that the FLASH few first dwords must be clear to 0xFF in order for the BOOT ROM code to start working, and I do clear them using the JTAG
However the ROM refuse to connect over serial.

What do I do wrong? Where the hell is the instructions or documentation about the ROM-Version of boot-loader.

Linux/DRA746: Whether J6 Android release camera application support Ethernet camera ( H.264 stream mode ) ?

Part Number:DRA746

Tool/software: Linux

Hi Expert:

Customer connect Ethernet camera to J6 board. The Ethernet camera is H.264 streaming code.

Their software base is 6AL.1.2, use J6 DRA746 runing android system. 

We find that at /mydroid/hardware/ti/dra7xx/camera folder contain omxframedecoder.cpp, it contain MJPEG and H.264 camera support.

Does TI android 6AL.1.2 camera application can support use IVAHD decode camera H.264 steaming and preview to LCD?

if TI android release did not support it, whether can provide some example about run H.264 decode at camera HAL layer?

Because we find that at 6AM.1.2 TI have removed omxframedecoder.cpp contain H.264 support feature.

Best Regards!

Part Number:TMS320F28027

Dear all,

I am studying on TMS320F28027 and I am trying to synchronise PWM output with analog comparator signal. To achive that, I am creating an event signal (DCAEVT1) for low and high level of comparator and going a tripzone interrupt.

When controller recieves SWFSYNC signal, PWM module is supposed to load 0 (zero) as phase value and it will load pwm counter register with zero. Thus, pwm will be restarted.

I have two problem on that step;

The first one is; SWFSYN register cannot be set 1. It is alwasy zero. Therefore, I cannot get synchronise signal.

The second one is; When I set PHSEN bit as 1, which is located in PWM registers, TBCTL register, PWM output is always high. I can observe a high level output.It never goes down.

Best Regards,

Fahri

Starterware/AM3359: PMIC TPS65910 Booting Issue

Part Number:AM3359

Tool/software: Starterware

Hi,

We are using PMIC TPS65910 for our custom board and we are using starter ware Boot loader code for Booting through UART0. The processor gets reset while executing functions related to PMIC voltage configuration.

Functions are

1. ConfigVddOpVoltage();

2. SetVdd1OpVoltage(oppTable[oppMaxIdx].pmicVolt);

While executing those function the processor gets reset.

The Flow of booting is

1. Power on the Device.

2. 'CCCC....' will appear .

3. We will send the boot loader code through x  modem.

4. After sending the code the system gets reset and prints 'CCCC...." on screen.

To confirm that reset occurs while executing those function only, we are executing those functions after UART0 console utils initialization and printing some statements.

Why it is resetting the device and how can we debug the problem?

Thanks & Regards

Dear engineer;

The datasheet provide the "Frequency VS magnitude" curve, and the -3dB bandwidth could get to 93MHz. But there is one customer who test it and the -3dB bandwidth is much less than 93Mhz, please refer the result he tested.

TPS65218: GPIO3 pin of TPS65218

Part Number:TPS65218

Hi,

I have one question regarding GPIO3 pin of TPS65218.

I know GPIO3 pin can be used as RESET pin.

My customer does not use this pin. But customer would like to know why GPIO3 pin is in PMIC.

Because TPS65910x PMIC does not have RESET input pin same as GPIO3. And TPS65218 is newer than TPS65910x. I think this means GPIO3 pin is added by some reason.

But I don't know the reason (the situation is needed RESET to PMIC). I think it is enough to have RESET signal to Processor. Why is GPIO3 pin in TPS65218 PMIC?

Please advise me.

I appreciate your quick reply.

Best regards,

Michi

Hi all

Would you mind if we ask TLV3204AIC3204?


<Question1>
There is the description "5.2.1 Page 0 / Register 0: Page Select Register - 0x00 / 0x00 (P0_R0)" on the document SLAA557 P96.
What does it "Summary of Memory Map" mean?
It means "Summary of Register Map", doesn't it?
(It is the same as "Page 1 / Register 0: Page Select Register - 0x01 / 0x00 (P1_R0)" on the document SLAA557 P123.)

<Question2>
There is the description "5.2.16 Page 0 / Register 16: Reserved Register - 0x00 / 0x10 (P0_R16)" on the document SLAA557 P99.
We guess that usually Reserved Register allows to read only.
Why can this register write? And what purpose does it use for?


Kind regards,

Hirotaka Matsumoto
