DS90UB940-Q1: How to set up BIST function

$

0

Part Number:DS90UB940-Q1

Hi,

I used DS90UB940-Q1 as Deserializer and DS90UB925Q-Q1 as Serializer. I can receive the normal signal. But I followed the guide in the datasheet to set up the BIST function and the PASS and LOCK pins are always low.

Could you please explain the detailed steps of building BIST function between DS90UB940-Q1 and DS90UB925Q-Q1?

Thanks.

ADS1299: Cannot disable / stop data ready signal

Part Number:ADS1299

Hi Folks,

I have a custom board with ADS1299 (the 8 ch version). I am using the SPI_MODE1 and 10 MHz clock rate. To see, what I have done, I check the SPI clock and the /DRDY signal on oscilloscope.

The problem is that I would like to stop /DRDY signal: it is my interrupt source, so I have tried SDATAC and STOP commands too without success. On the oscilloscope I see the data ready.

To validate my communication, I set the data rate to 2kSPS (instead of the default 250SPS), then read the registers back and it seems to work: the CONFIG1 register contains the right value and on the scope I also see the /DRDY signals with the new frequency.

Can anybody help me, what did I miss?

Regards,

Norbert

Part Number:AM3352

Tool/software: TI-RTOS

Hi

       I am testing UDP data with the NDK. When I call the sendto function,

It returns -1 and then I call fdError().Check the error code, the received error code is 6,

where I have not configured?

this is my test code:

void ftpserver_thread_entry(UArg a0, UArg a1)
{

    SOCKET sclient = NULL;
    struct sockaddr_in sin;
    char * sendData = "1234567890";
    memset(&sin, 0, sizeof(sin));
    sin.sin_family = AF_INET;
    sin.sin_port = NDK_htons(5555);
    sin.sin_addr.s_addr = NDK_htonl(INADDR_ANY);
    int len = sizeof(struct sockaddr_in);
    int ret = 1;
    ret = fdOpenSession (TaskSelf ());//必须在第二级的任务调用才能成功??why???
    UART_printf("fdOpenSession = %d\n",ret);
    sclient = socket (AF_INET, SOCK_DGRAM, IPPROTO_UDP);
    if(sclient == NULL)
   {
        UART_printf("socket open failed\n");
        return;
        }
    else
    {
        UART_printf("socket open successful!\n");
    }
     if (bind(sclient, (struct sockaddr *)&sin, sizeof(sin)) < 0)
     {
        UART_printf("bind failed!\n");
    }

    while (TRUE)
    {
        ret = sendto(sclient, sendData, strlen(sendData), 0, (struct sockaddr_in *)&sin, len);

        UART_printf("sendto result = %d\n",ret);
        ret = fdError();
        UART_printf("fdError = %d\n",ret);
        Task_sleep(10000);

Part Number:TMS320F28377S

Hi

My customer use 28377+ FPGA(spartan6) to extend 2pcs RAM(512K) and Flash(128K), double check with you about the hardware design and software change.

CPU1RAM is enabled by 74LV32

F28377

FPGA

Use CS2 to extend RAM1 RAM2, CS4 is used to extend Flash, read and writing controlled by FPGA

Change example code as below

emif1_16bit_asram.c

Set IO to function 2 as expansion port

GPIO92 used for XA19, No changes in others code.

CCS7.4 MEMOREY observation

1. Write a 32-bit data, only the upper 16 bits have been written in, the address value will be cleared immediately when next statement is executed.

2. When writing to address 0x100002, the address line A0-A4 is 1000; How to configure XA19? is it necessary to set?

3. Emif1ConfigRegs.EMIF1MSEL.all = 0x93A5CE71; After write in, the read out data is 01?

Thanks a lot.

Hi

My customer is developing and testing Portable MP3 Player with BQ25890.

Most Quick Charger chargers support 9V, 5V charging as well as 12V.

Is there any way to control the Quick charger to 9V on the bq25890 side?

Please check it.

Thank you

BQ34110: GPC Cycle is not changing the States

Part Number:BQ34110

Hi,

We are performing GPC Cycle to learn Full charge capacity and other parameters.

Discharge Endpoint (10V) and Charge Endpoint(14.6V) are updated according to our Battery pack.

But after starting the GPC Cycle, Precycle Discharge block is not changing the state to precycle relax block even after reaching the pre-cycle discharge endpoint.

States are changing only when Board is Turned OFF and ON. Is this how GPC Cycle works??

Please suggest where we are facing the problem and Let us  know the proper procedures we need to follow in GPC Cycle.

Part Number:BQ24780S

Hi,I am from ASUS SZ NB POWER Team.We have some questions about bq24780 now.Our protection use the independent comparator of bq24780(when CMPIN pull high,CMPOUT pin's output is low,our protect will be enable).We find independent comparator doesn't work at the second protection after ACFET is latched off .

we can find COMPOUT pull  low when AC_BAT_SYS  is up to 25v at the first time.however,when AC_BAT_SYS  pull up to 25v again,COMPOUT doesn't pull low.Can you give a reason for this?Our ovp is under 26V,which is charge IC's ovp.In normal operation,our ovp will work before charge IC trigger ovp.

Before ACFET is latched off,our  ovp works normally with bq24780's  independent comparator.There is a picture about it below.

.In fact ,COMOUT can change its level when the ACFET is latched off.It fails to work after several  transformation.

we find that the independent comparator fails to work .COMOUT pull high when COMIN arrive at 2.372v.

What is the difference between ACFET is latched off or not?Why independent comparator dosen't work persistently? And we want to know how to make sure that the independent comparator will  work normally.

Thanks!

LM317: Drop out mode operation

Part Number:LM317

Hi,

We are using LM317 IC for regulation purpose ,where input voltage is 24V . Now with the output resistor settings I am getting 20.5V as well as 23.5V. But the datasheet says minimun headroom of 3V has to be given between input and output for the the IC to operate in regulation mode if the headroom is not provided it works in drop out mode. My concern is if the IC is operating in drop out mode and operating for a long time what effect will it have on Thermal condition of the IC, Stability and in drop out mode how long is it possible to operate without any failure?

Please provide the details ASAP.

Thank you

Respected TI community

Greeting!! I want to confirm if the TMDSSOLAR(P/C)EXPKIT has a data acquisition capability or not? In the watch window, I am able to see the continuous values of voltage, power and current. Can these values are stored in any type of array, where I can used these stored values later?

Part Number:DRV8323R

(Please visit the site to view this file)Hi,

We are using DRV8323RS in 1x PWM mode

We are able to read and write the values on registers through SPI.

Default values are correct according to datasheet.

But when we are changing it into 1x PWM mode by changing the values of registers. Its show fault.

We have set the values as shown below in registers->

Driver Control Register (address = 0x02) ==> 0x0040

Gate Drive HS Register (address = 0x03)==> 0x0388

Gate Drive LS Register (address = 0x04)==> 0x07AA

OCP Control Register (address = 0x05)==> 0x0159

CSA Control Register (address = 0x06)==> 0x0283

Then it shows Fault according to below registers

Fault Status Register 1 (address = 0x00) ==> 0x0500   (Fault +Indicates gate drive fault condition )

Fault Status Register 2 (address = 0x01) ==> 0x0004  (Indicates gate drive fault on the B low-side MOSFET)

And on GHx its giving 24v and on GLx its giving 0v

And I have attached schematic also, please review it. 

Connections-:

We have connected MCU with EVM according to 1x PWM Mode


Enable pin ==> MCU GPIO (Write High)

SCLK pin ==> SPI Serial clock pin

SDI pin ==> MOSI

SDO pin ==>MISO

nSCS pin ==>Chip Select

INLC (Brake)  ==>MCU GPIO (Write High)

INHC (DIR)  ==>MCU GPIO (Write HIGH)

INLA  ==>HALLA of motor

INHB ==>HALLB of motor

INLB ==>HALLC of motor

nFault ==> MCU GPIO (Read High) No fault case

Cal ==> MCU GPIO (Write LOW)

Power Supply 24v

Please help to solve this issue. Thanks in advance.

Dear,

Based on TI recomendation regarding PCB Tracks impedance of FPDLink, we have this table:

Since you have to measure the S parameters working in PoC mode, I mean single ended, could you confirm, which is the proper way to do this measurements?, with VNA. As far as I understand:

Measurement of S11 parameters, 954 IC has been removed from the PCB, and two termination resistor has been soldered 

In this case, to measure S21 Paremeter.
