Part Number:BQ24297

Hi,

We meet an issue about BQ24297 can't normally turn on, please see below SYS pin waveform, BATFET turn on/turn off each ~170ms, seems meet some error after turn on BATFET, but I check the register only see the REG09[7] WATCHDOG_FAULT is 1. And other strange is REG01[5] OTG Enable is 1.

This symptom can be release after remove battery, we have 2 device, we have tried one to remove battery, and keep one still have this fail symptom.

Do you have ever meet this issue or any possible fault caused BATFET can't turn on normally?

CH1: SYS pin

CH1: SYS pin

CH2: BAT pin

Thanks!

Part Number:AM26LV32

The supply and reception buffer for RS422 differential signal, the power supply voltage is on the transmission side (5V) and the reception side (3.3V)
Does it work without problems with the circuit configuration?
Also, if there are points to be taken care of by termination resistance etc., please teach me.

CC2640R2F: Can CC2640R2F judge the transformation power when doing the advertisement?

$

Part Number:CC2640R2F

Hi, Sir.

I am using the CC2640R2 board. I develop a Bluetooth beacon which can only be scan inside a room, but can not be scan outside the room when someone just go out of the room. I think about reduce the transformation power of the advertisement, so that the advertisement is only in the range of this room. I look at the board SDK, API and the SimpleLink Academy 3.10.01.00.  I cannot find any function or variable can setup the transformation power. 

Do you know that whether the CC2640R2 board can setup transformation power or not?

Regards,

Robert

RTOS/SN65DSI86: SN65dsi86 DP link training failure .

Part Number:SN65DSI86

Tool/software: TI-RTOS

Hi sir, 

 I have a success experience on SN65dsi86 to light up some panel before.

 But , recently I got a new panel and got a new issue during DP link training period.

 Can you help us to advice and clarify and to solve this problem as following information ? thanks.

   

    1) Panel  INFO : AUO 14" (B140HAN03.1) , 1920x1080P FHD  , using DSIAx4 lanes  , DPx2 lanes , DP Max datarate(HBR 2.7G)

    2) I write and simplify to DSI initial code that only doing DP-link-training operation . 

      -----------------------------------------------------------------------------------------------------------------------------------------------------------------------   

 23 FF 7 //PAGE_SELECT to "TI Test Registers"
 23 16 1 //ASSR_OVERRIDE: to ASSR_CONTROL is read/write.
 23 FF 0 //PAGE_SELECTto "Standard CFR registers"
 23 0A 2  //REFCLK_FREQ/DPPLL_CLK_SRC : 19.2M external clock
 23 10 26 //Chanel A, B and lanes
 23 12 54 //DSI A Clock range
 23 94 80 //DP_DATARATE
 23 5C 1  //HPD_DISABLE
 23 0D 1  //DP_PLL_EN
 FF 0A     // delay 10ms
 23 64 0  // 0x64~0x73 AUX_WDATA0 through AUX_WDATA15 => Disable ASSR mode
 23 74 0  //AUX_ADDR[19:16]
 23 75 1  //AUX_ADDR[15:8].
 23 76 0A //AUX_ADDR[7:0].
 23 77 1  //AUX_LENGTH
 23 78 81 //AUX_CMD.
 FF 0A     // delay 10ms
 23 5A 4  //VSTREAM_ENABLE/ENH_FRAME_ENABLE/ASSR_CONTROL => Disable ASSR mode
 23 93 20 //DP_NUM_LANES/SSC_SPREAD/SSC_ENABLE/DP_PRE_EMPHASIS
 23 96 0A //ML_TX_MODE: Semi-Autolink
 FF 14      // delay20ms
 23 5A 0C   //VSTREAM_ENABLE/ENH_FRAME_ENABLE/ASSR_CONTROL

    -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

  3) After that DSI initial operation,  I got the dump of sn65dsi86 register as the comparation as below.

      The left side is our OK AUO panel 12.5" that semi-auto-link training is pass ,the right side is our new panel AUO panel 14" the semi-auto-linktraining is failed.    

      The  Linking training & IRQ status shows :

           @ 0x96 = 0x01:  ML_TX_MODE is set to  "Main link off" that mean training failed.

           @ 0xF8 = 0x06:  That mean training failed and got the LT_CR_LPCNT_ERR flag.

                   LT_CR_LPCNT_ERR. This field is set whenever link training fails in the clock recovery phase due to
                   same VOD being used five times.

       So I have tried to enlarg the wait time to 1 second , but AUO140 is still not sucesss , AUO125 is OK.

RTOS/LAUNCHXL-CC2640R2: Possible to turn off Bluetooth functions such as advertising in multi_role or SimpleBLEPeripheral?

Part Number:LAUNCHXL-CC2640R2

Tool/software: TI-RTOS

I'm trying to save as much power as possible when power_sleep()-ing my device to standby mode. With multi_role and SBP, the device is waking up periodically from standby mode to scan for Bluetooth connections. I want it to stay in standby mode, and not wake up.

Maybe if I disable part of the or even the entire Bluetooth protocol, then it will stay in standby. Then when it powers back on, I can restore the Bluetooth.

Is this possible? If so, how? Thank you in advance.

Hi,

I am running C code on C66X,and I want to know how to optimizate the cycles of the code.

My code is :

float A[1728],floatB[1728],float C[1728];

float sum1 = 0, sum2 = 0;

int  i=0;

for(i= 0;i<1728;i++)

{

sum1+=A[i]*B[i];

sum1+=A[i]*C[i];

}

Is there anyway to make it running faster?

Thanks.

Part Number:TDA2PXEVM

hi all,

i have the following path:

DispDistSrc -> Merge -> VID1

capture -> VPE -> Merge

As the path 1 into Merge link is ARGB8888 format, but VPE can only transfer to RGB888 format, so path1 can show normally , but switch to path2 can not show normally.

how can i modify the parameter of VPE link that make the path2 can show with ARGB8888 format ?

best regards!

After using UBL for the first time, successfully upgrade HostTestReleaseCC2540USB-UBL.bin. 
When I want to upgrade again. I follow the way shown in the TI_BLE_Sample_Applications_Guide.pdf help documentation (picture).
Pressing the button while powering up, UBL only appears for one second. I didn't have time to upgrade it, just run HostTestReleaseCC2540USB-UBL.bin.
I want to extend this UBL stay time, but I have not found a valid modification method in the UBL source code provided by BLE-CC254x-1.4.2.2.

Part Number:LMP90100

Hello,

I am able to read data through 4 channels successfully. Now i wanted to enable SPI reset feature by writing 0x01 to SPI Reset Register (ADDR 0x02). But after enabling this feature, all i am getting from ADC is garbage values from all 4 channels. Is there a specific way to enable this feature as i could not get anything like that from the data sheet.

Thanks,

I have ordered bq27z561evm-011  www.ti.com/.../bq27z561evm-011.

I need to evaluate various parts on this board, especially the fuel gauge and the BQ25892 charger.


Kindly share the complete schematics(for the lithium ion chargers and other components) of the boards as the eval board datsheet has only schematics related to the fuel gauge IC.
