Part Number:RM48L952

Tool/software: Code Composer Studio

the ccs version is ccs for ARM 6.2.0,the device is RM48L952 the complier is Ti V15.12.3.
in the release mode,the *.out file size is 750,768 bytes. if clean and bulid again the *.out file is 750,784 bytes. why the size of the executable file is different? does the different can make the logic function wrong of the program? in  the debug mode, the size different when clean and build, and the optimization is closed.

Hi Ti Guys,

We kick off new product using Ti mmwave sensors.Now I have some questions listed .

1.I need to fork new task to get range,velocity and angle.So how to fork new task in MSS?Do you provide sample code ?How to get range, velocity and angle in the code?

2.For different RCS,such as pedestrian, car or motor, the sensor need to dectect at the different ranges.How to design this scenarios. Which ti demo are closet to this scenario?

Thanks

DRV110: Ipeak and Ihold setting

$

Part Number:DRV110

Hello team,

Can Ipeak and Ihold set to 1A, 330mA?

In the datasheet, current is set by Vref and Rsense and Vref is set by resistor.

Recommended resistor value is from 66.67k~2M and 66.67k~333k and if Rsense is 1Ohm, maximum peak is 900mA.

If Rsense is below 1Ohm(for example 0.5Ohm), can Ipeak and Ihold set to 1A and 330mA?

Thanks.

  I am facing some issue on migrate to azure sdk(2_20) to my current project cc32xx_sdk_2_20_00_10.

  I added all libraries in project->properties->include options and File search path. I added sdk project->properties->general->CC32XX SDK Azure IoT Plugin.

   If i add azure library in my project (ex : #include "iothubtransportmqtt.h") i am getting error on this file crt_abstractions.h"

 If i import C:\ti\azure_cc3220_2_00_00_07\examples\rtos\CC3220SF_LAUNCHXL\azure\iothub_client_sample_mqtt example project i am not getting any error compile successfully.

 Why i am getting error please help me to solve this issue.

Thank you

Part Number:CC3220S-LAUNCHXL

Tool/software: TI-RTOS

Team,

Can we modify the code in CC3220  to return modules MAC address using the HTTP GET API  for returning device name i.e /param_device_name.txt ?

Or can we add an additional API along the provisioning API (I don't want to start another http server), to retrieve modules MAC address ?

DS90UB927Q-Q1: Capability for 1280 x 800 60Hz

Part Number:DS90UB927Q-Q1

Dear, Sir.

My customer is considering to use DS90UB927Q-Q1 for VESA 1280 x 800 60Hz

(max 1680 x 828 60Hz, hencepixel clock = 83.46MHz).

Just focusing the pixel clock, DS90UB927Q-Q1 could be OK because its max is 85MHz.

I would like to confirm DS90UB927Q-Q1 would be suitable for VESA 1280 x 800 60Hz?

because the internal buffer limitation was concerned.

Please give your advice.

Best Regards,

H. Sakai

Linux/PROCESSOR-SDK-AM335X: AM335x and linux system use dmtimer to make a timer , can't change the frequence by change the value of tldr ,tcrr

Part Number:PROCESSOR-SDK-AM335X

Tool/software: Linux

hi:

I want to make a timer in linux by use dmtimer drive,hardware is am335x.

the fclk  is 24000000Hz。

when the couter an load value is (0xFFFFFFFF-500) ,the interrupt function could  work ,but the frequece  is 390kHz,   the range of the value is to 0xFFFFFFFF-500   to 0xFFFFFFFF- 0x0000FFFF, the fre is always 390khz on the scope. when set the value to 0xFFFFFFFF - 0xFFFF0000 , can't measure wave on the scope.

so how to config the cpu register  can mak the frequece work right?

the interrupt funciont is below 

static irqreturn_t mytimer_interrupt(int irq, void *dev){
        
    //printk(KERN_ERR"TIMER 7 is_running !!!!!!!!!!!!\n");
    char gpio_v = !(gpio_get_value(GPIO_TO_PIN(3, 21)));
        gpio_set_value(GPIO_TO_PIN(3, 21), gpio_v);        
    return IRQ_HANDLED;
}

the drivce init function is  below:

 timer = omap_dm_timer_request_specific(7);    //得到定时器7
    irq =  omap_dm_timer_get_irq(timer);        //得到中断号
    ret = request_irq(irq,mytimer_interrupt, IRQF_DISABLED | IRQF_TIMER , "heat_timer_init",NULL);//注册中断
    omap_dm_timer_set_load(timer, 0, 0xFFFFFFFF-500);
    omap_dm_timer_write_counter(timer, 0xFFFFFFFF-500);

    /* Enable overflow interrupt */
    omap_dm_timer_set_int_enable(timer, OMAP_TIMER_INT_OVERFLOW);
    /*
     * Set counter value to overflow counter after
     * one tick and start timer.
     */
    //omap_dm_timer_set_load_start(timer, 0, load);
    // start the timer!
    omap_dm_timer_start(timer);
    // stop the timer!
    //omap_dm_timer_stop(timer);

Hi Sir,

This question should be not related to some TI's product so please help me on this problem.

How to design to THE EARTH GROUND PORT of PCB? ( I do not find the exact word to descript this phenomenon)

Should it belong to ESD characteristics of INPUT PWR SUPPLY?

Hope you're responding soon.

66AK2G12: DDR3L routing specification

$

Part Number:66AK2G12

Hi,

My customer is now designing their custom board with 66AK2G12. Now they are checking DDR3L routing specifications described in the datasheet and has some questions:


1. It appeared that they could not meet the specification CARS33 in Table 7-11. CK and ADDR_CTRL Routing Specification. It suggests 125ps (max), but actually 175ps in their current design. Is this critical violation in routing requirement ?  Or, is this relaxed some, for example, "it is okay if they meets CARS31+CARS33 < 625ps". Could you comment ?

2. They can`t understand what is actually specified by DRS35 in Table 7-12. Data Routing Specification. Could you please explain more details ? Is this allowed skew within a byte lane ? 

Best Regards,
NK

BQ24170: Minimum input voltage to charge 3.7V battery at 4.2V charge voltage and 2A charge current.

$

Part Number:BQ24170

Hi,

We are designing a PCB with battery charger IC for 3.7V single cell Li-Polymer battery, Currently We are planning to use BQ24170 battery charger IC in our design.

Let me explain about what is there in our PCB

1.It has a buck regulator at the input side which supports wide range of input voltage ranging from 5V to 24V which gives us the stable 4.5V output.

2.Next this input is provided to the battery charger IC to charge the 3.7V LI-poly battery.

3.The last stage of the PCB is that it has a BOOST regulator that will take 3.7V battery input as well 4.5V from the above buck regulator(this is when the external adaptor is connected) to produce 5V, 3A output power.

Now my concern is that whether 4.5V is sufficient for the battery charger to charge the battery at 4.2V , 2A charge current?

Also suggest what is the minimum input voltage that is required to charge the 3.7Vbattery?

Please suggest we are choosing a buck regulator that provides enough current for the operation.

Request you to reply this ASAP.

Regards,
Karthik

Hi Ben-san,

My customer want to use UCC256304 for  Input DC90V-300V to output DC385V  200W  isolated DCDC.

UCC256302 or UCC256303 does not meet such a wide range input by BLK voltage range.

How about the HV pin connection to kill the X cap discharge function?

Please propose the cct of  Input DC90V-300V  to HV pin cct.

Part Number:LMH1219

There is a figure expressed by the first derivative in the data sheet.
Figure 11 represents the data I read,(Same information read from LMH1219)
Figure 12 represents the first derivative.

In my opinion, it takes special processing to make it like "SigCon Architect" data.
A detailed explanation of the first derivative is needed.
I would appreciate it if you could explain it using examples.
