Part Number:TIC12400-Q1
Hello Team, enclosed question from customer:
--
We are using the TIC12400QDCP*Q1 in one of our Design, and I’m working on the WCA of some blocks.
Please I need the value of the leakage current in the /INT pin “pin 24” in the high Z state,
This will help to complete some calculations.

Part Number:ADS8684
Hi,
We use the ADS8684 in one of our designs. We need to fullfill a 0.1% accuracy for all of the analog inputs and all the ranges.
So we plan to calibrate the inputs in software.
We use additional 1kOhm resistors on AIN_xP and AIN_xGND pins.
Do we have to calibrate all the ranges with different correction values or does the big part of the offset and gain error stays the same when switching the range?
Thanks and best regards,
Patrick
Part Number:BQ51050B
Hello,
We had discussion regarding this issue previously. Unfortunately we didn't got our issue resolved yet. Attached the scope waveform of Vrect (Yellow) and Vbat (Green) when the charger is connected. We have observed that once the Battery is protected from circuit by BQ29700 when the under voltage threshold of 2.8V is reached, the charger IC output w.r.t GND Vbat = 1.069V and is constant. Once the charger is connected it should output of Vrect-reg around 5.2V (If Vbat < Vlowv then Vrect = Vrect-reg) so that the voltage difference b/w BAT pin and V- of BQ2970 will be greater than 1.3V, therefore will release discharge control. But upon charger connection the Vbat and Vrect voltages are never reaching even 4.2V. Since during under voltage protection of BQ2970 its V- pin is pulled up to BAT voltage V- pin will be around 2.8V. Hence in order to release the protection BAT pin of BQ2970 should be supplied with 2.8V+1.3 = 4.1V atleast by the charger BQ51050B. What will be restricting the charger IC to constantly output around 1V to 1.5V as per attached scope waveform. Attached the schematic also for reference.

Part Number:TUSB4041I
Hi, Team
My customer is using TUSB4041I in their car infotainment product. They want to test Eye-Diagram on the Downstream Port through a long cable. They program the processor i.MX6 to test mode and send out data to TUSB4041I Upstream port. As there is no device connected to TUSB4041I Downstream port, so there is no data output from USB4041I Downstream port.
Could you suggest how to configure TUSB4041I to test Eye-Diagram on its Downstream port?
Thanks

Hello,
I am getting that hal_stdtypes.h generated by Halcogen contains all the possible data-types usable within the program and used by default by halcogen to create the other files (e.g. reg_system.h). If I had my own standards for naming the data-types, would it be possible to change the assignments made in hal_stdtypes.h?
Thanks ahead.
Regards.

Hello,
I am trying to boot a custom board with a SD card but it is not working. Therefore I stepped the code. The execution is going well untill a loop in the function BOARDGetDeviceCtrlModInstNum(...) (board.c) ==>
The next step is going at the adress 0x00030010 and after a few more steps the execution gets stuck at 0x0003008c. I can't find why.
The file that I am debugging is : bootloader_boot_mmcsd_a9host_debug.bin (Which I renamed MLO for the sd card and loaded at the address 0x402f4000)
Does someone have an idea on how to solve this problem ?
I am using :
CCS 8.3
sdk rtos 5.03.00.07

Hello
We are incorporated DDP4422 with 0.65' (65 1080p 2xLVDSType A DMD) in our product.
We are now planning to use same DDP4422 with 0.95' DMD (0.95 1080p 2xLVDSType A DMD).
Can it be feasible? Are two DAD2000 chip is necessary for this kind of implementation?
Thanks

Hi,
I have a project that was customized by blestack/simple_pheripheral project. Then I need to add Off_Chip OAD Property to that project. To do that, I want to customize blestack/oad_off_chip and I ported my code to that example. In my original code, I used additional thread so I tried to add a thread to that example but somehow I cannot do that (I created another issue about that and its process in progress).
Because of that, I changed my code structure to remove the additional thread and I created a clock. In that clock callback, I tried to read my I2C sensors periodically but I could not.
When I try to read the sensors in "SimplePeripheral_processCharValueChangeEvt" function for example (I used to start my additional thread via BLE command in my old code) for just one time, it works. But, when I tried to read sensors in timer callback function it does not. But timer works because I toggled a led in the callback function.
Here is a code example that explains what I mean;
static void DD_SystemGeneralTimerHandle(UArg arg)
{
#ifdef OLD_STYLE_CODE
GPIO_toggle(Board_GPIO_LED0);
#else
GPIO_toggle(Board_GPIO_LED1);
uint8_t txBuffer[1];
uint8_t rxBuffer[6];
I2C_Transaction i2cTransaction;
txBuffer[0] = WHO_AM_I_REG;
i2cTransaction.slaveAddress = SENSOR_ADDRESS;
i2cTransaction.writeBuf = txBuffer;
i2cTransaction.writeCount = 1;
i2cTransaction.readBuf = rxBuffer;
i2cTransaction.readCount = 6;
I2C_transfer((*i2c), &i2cTransaction); //there is no stucking, it just cannot read, it return false
#endif
}
static void SimplePeripheral_processCharValueChangeEvt(uint8_t paramID)
{
switch(paramID)
{
case CUSTOM_PROFILE_CHAR1: //Working mode characteristic
SimpleProfile_GetParameter(CUSTOM_PROFILE_CHAR1, Characteristic_1_Run_Time_Read_Value);
if(Characteristic_1_Run_Time_Read_Value[0] == 0xBA) //start sensor reading here for example
{
#ifdef OLD_STYLE_CODE //I used to start additional thread here before
myThread_create();
#else //there is no error in here
GPIO_init();
I2C_init();
SPI_init();
/* Create I2C for usage */
I2C_Params_init(&glb_i2cParams); //glb_i2cParams this is global static variable
glb_i2cParams.bitRate = I2C_400kHz;
glb_i2c = I2C_open(Board_I2C_TMP, &glb_i2cParams); //glb_i2c this is global static variable
if (glb_i2c == NULL)
{

Hi Team,
We just want o know the negative maximum input voltage rating for the Switching output of the internal DC-DC output from the PMI(TPS65910). Please let us know we had gone through the datasheet but it is not clearly specified in Electrical Specification Section. We are trying to tune Snubber on the output voltage rail of 1.1V and 1.5V to reduce Overshoot and undershoot observed as per reference waveform attached here with.
Please let us know the negative voltage limit for switching node so that we can make decision for the requirement of Snubber circuit tunning.

Hi,
I have a problem running the radar without an external user,I saw through the forum a way to run it on my own but it does not work according to the settings I sent to it (but its running).
I add the code here, you can tell me what I'm not doing well?
thanks...

Hello,
SETUP:
hardware used: TSW1400, ADS52J90
software used: HSDC Pro GUI v5.0
HMC-DAQ GUI V2.8
Matlab code used: C:\Program Files (x86)\Texas Instruments\High Speed Data Converter Pro\HSDCPro Automation DLL\Manual and Examples\Automation DLL Matlab Example\64Bit Matlab
PROBLEM:
when I use the provided matlab code, ADC device can be selected and the HMC-DAQ GUI can be launched by HSDC Pro GUI, however, the HMC-DAQ GUI setup cannot be automatically setted, for example, item 3, choose data Format cannot be automatically chosen. I need to manually set them. But if I manually set them up, the configuraton settings in the later code such as 'Passing ADC Output Data Rate', 'Set ADC INput Target Frequency' will not be valid. Is there a way, that the Matlab code can automatically setup the HMC-DAQ GUI as I want?
Best regards,

Part Number:TPS7A05
Is it applicable to connect directly each output pins of 2pcs of TPS7A05 as below figure?
Condition
- VIN: 5.0V
- VOUT: 3.3V (TPS7A0533)
1.8V (TPS7A0518)
- EN pin: Enabled only one or the other
I suppose that there is no concern because not exceeding ABS Max, is my understanding correct?
Please let me know if you have any advice.
Part Number:LAUNCHXL-CC2640R2

Hi,
I have a customized blestack/simple_pheripheral project and I tried to add OAD property over on it. To do that, I followed this link: http://dev.ti.com/tirex/content/simplelink_cc2640r2_sdk_1_40_00_45/docs/blestack/ble_user_guide/html/oad-ble-stack-3.x/oad_offchip.html#add-off-chip-oad-to-an-existing-project
I did ever steps in the link (except "optional" ones) and while doing that, I just cannot be sure about step-5 and I directly replace the "cc26xx_app_oad.cmd" file (under app/TOOLS) in the original blestack/oad_off_chip example with my original code's related file (copy and paste).
After I did the whole steps in the link, I tried to compile my application project, I got this error "Description Resource Path Location Type #1965 cannot open source file "oad_target.h" simple_peripheral.c /simple_peripheral_cc2640r2lp_app/Application line 22 C/C++ Problem".
I tried to find "oad_target.h" file in my SDK and also I could not do that.
How can I overcome this problem?
Note that, my customized simple_pheripheral example code is so close to the original one except that I use 32KHz-Crystal-Less mode configuration. Maybe this affects your thoughts.

Hi,
I have a question in a previous E2E post.
I would like to check Lock Status in register "00h". Which bit should I check?
Since there is one register for 4 channels of video input, it can not be determined which camera is out of sync.
Is this register confirming the sync signal on the output side?
Or should we look at another register?
Best regards,

Dear TI Experts,
Anybody please answer How Voltage loop and current loop feedback compensation components values are calculated in PMP8740?
That means how TI arrived the values of R3=68.1K, C2=0.1uF, C1=2200pF for voltage loop and R37=150K, C13=0.022uF, C12=560pF in full bridge converter schematics.
Could you please share me the design calculations?
Regards
