Part Number:AWR1642BOOST

My customer has the below question:

Is there is an option to dump raw .bin files that I can load in MATLAB on my own for processing, is there a place that the file structure of that file is listed?

Part Number:AWR1642BOOST

Hello, My customer has the below question:

Once the chip is configured the way we want and the radar system is operational how do we program a stand-alone chip? Is there another dev kit or program kit that allows a chip to the “press fit” for a flash then removed for installation on a substrate? This will not be a production level operation but a simple test of  substrate compatibility and in house design technique experimentation

Part Number:TPS51200

1. TPS51200 part can source up to 4.5A max and sink up to 5.5A max (mentioned in datasheet spec). But in TI site it is mentioned as

 can you please confirm if it can support 4.5A and 5.5A max?

2. our requirement is to power 10*DDR3 ICs. so there are 14 address lines,6command lines and 3 control lines=28 lines in total. 12mA for sourcing and 13mA for sinking.

for one IC, VTT current =28*13= 0.35A 

If same memory controller is connecting channel A to 5*DDR3 SDRAM and Channel B to another 5 DDR3 SDRAM where address, command and control lines are common, how the source and sink current will get affected here? will it be For 10 IC, Current is 3.5A ?

Kindly revert at the earliest.

Thanks and Regards,

Part Number:CC1310

We are trying to implement address filtering for an address that is not immediately after the header. Is addrConf.addrPos meant to be used as an offset from the end of the header? The description "Nonzero to extend address with sync word identifier" does not sound like it. If this is not the correct parameter then is there some other way to implement address filtering for an address that is deeper inside the payload?

Tool/software: Code Composer Studio

I am looking at an application where i need to implementing an algorithm on samples obtained simultaneously from a pair of inputs. Can the ADC14 module be used with driverlib?

To clarify, when 2 external inputs are used, which of the following occurs:

a) The sample and hold module samples all inputs simultaneously but conversion occurs one after the other with each channel result stored in a separate memory buffer.

b) The sample and hold module will perform a full sample and convert cycle on one input channel, then proceed to perform another sample and convert cycle on the next channel.

Approach a) will be ideal for my algorithm. 

Part Number:ADS1256

We are using the ADS1256 to digitize 8 channels of single-ended information. Because our system is 5 V full scale on all inputs, we are not using the PGA or inbuilt buffer. I read an earlier discussion that suggests capacitors may need to be connected to the inputs of the ADC to maximize settling time. Are they tied to system ground or to AINCOM, and hence the 2.5V reference?

Hi,

We are running Rear view panorama usecase in VisionSDK3.1. Image sensor is 0V10640 and it is working in linear mode (not HDR).

When a headlight comes in the scene, it looks better/smaller when headlight is in center of the frame. As the headlight move towards edges or corner of the frame more spreading is observed. What can be the reason for this ? More weight/preference is towards the center now.

How can we change this so that headlights falls corners also looks better ? We checked TRM and could not find anything related to this. Please give your suggestions on this.

Part Number:MSP-EXP430FR5994

Tool/software:TI-RTOS

Having installed TI v16.9.6.LTS into CCS 7.4.0.00015 running under Windows 10 Home v1709 (64-bit) the bigtime_MSP_EXP430FR5994_TI example project fails during Task_construct.

Source file bigtime.cpp, line 151.

Something wrong with memory?

During debugging as follows:

main() at bigtime.cpp:151 0x01153A    
and step into    Task_construct(&task0Struct, (Task_FuncPtr)clockTask, &taskParams, NULL);

ti_sysbios_knl_Task_construct(struct ti_sysbios_knl_Task_Struct *, void (*)(unsigned long,unsigned long), struct ti_sysbios_knl_Task_Params *, struct xdc_runtime_Error_Block *)() at bigtime_pe430X.c:10 076 0x012D52

line 682   and step over    tsk->priority = params->priority;

tsk->priority has old value (-1 or 0xFFFF) instead of params->priority equal to 1 as default

Next statement, line 685: if (params->stackHeap == NULL)

stackHeap is a pointer and has value = 0x00000000::     stackHeap    struct xdc_runtime_IHeap___Object *    0x00000000 {__fxns=0x00F0D032 {__base=???,__label=1073692671}    0x00002B6C    
and is compared to NULL
which is defined within std.h:

/* NULL must be 0 for C++ and is set to 0 in C to allow legacy code to

#undef NULL
#if defined(__cplusplus) || !defined(xdc__strict)

#define NULL ((void *)0)
#endif

Debugger evaluates (params->stackHeap == NULL) as false
and the next statement, line 689:    tsk->stackHeap = params->stackHeap;
step over
and nothing happend:      tsk->stackHeap points to 0xFFFFFFFF instead of to default 0x00000000.

Later on, the local stackSize changes value from 0 to the correct 512.

tirtos.mak shows that tirtos_msp43x_2_20_00_06 was generated (I assume) under the following conditions:

older compilers:

ti.targets.arm.elf.M4F        ?= $(TI_INSTALL_DIR)/ti-cgt-arm_15.12.1.LTS

XDCTOOLS:
XDCTOOLS_INSTALL_DIR        ?= $(DEFAULT_INSTALL_DIR)/xdctools_3_32_00_06_core

I created a bunch of copies of the tirtos_msp43x_2_20_00_06 directory and compiled TI-RTOS
with TI v16.9.6.LTS with debug and release for both xdctools_3_32_00_06_core and xdctools_3_32_02_25_core.

Task_construct() works fine within ampty_min example but still fails when running bigtime.

It is my first post on this forum.

Your help is very appreciated.

Part Number:BQ25122

Hello guys,

We are using BQ25122 module in our current design to charge and manage the battery. The board is designed, manufactured and assembled. We did some tests today and we measured 1.2V on the VSYS pin. However, in section 9.2.2.1 of a datasheet, it says VSYS default is 1.8V.

1.8V of voltage is enough for our processing system to power up and to establish I2C communication with BQ25122 and set the desired value on VSYS output pin (to 3.3V). 1.2V that we currently have are unfortunately not enough so we are now stucked.

Is there anything we are missing here? What is the default voltage on VSYS output pin ?

Thank you very much for your time and effort.

Sincerely,

Bojan.

I read that these are included in the CCSv7 installation, but on one of my machines the XDS510USB is not recognized. Is there somewhere I can find the driver for this part?

Part Number:F28M36P63C2

We occasionally get I2C_MASTER_ERR_ARB_LOST errors while using using the I2C module in the MWare/driverlib libraries (v207). However, we only have a single master on this bus.

There is an I2C driver between the MCU and the peripheral devices (see below schematic) which we have added because there is a long physical distance separating them, ~1 meter. Would the presence of the I2C driver cause the MCU to think it would lose arbitration when starting an transaction? When I examine the SCL and SDA lines, they are both held high, which means the bus is free. So I am wondering why the MCU cannot gain control of the bus.

Part Number:MSP432P401R

Hi all,

I have a device with 3 rotary encoders that output a pulse whose duty cycle changes proportionally to the angular position of the shaft. So, to read the angles, I need to determine the time difference between the rising and falling edge of of each pulse. I know that I need to use the capture function of Timer A, but I'm not sure how to do so.

Another issue is that I'd like to perform ADC conversions and read SPI messages at the same rate frequency to send them to a PC via UART. So basically I'd like to read the pulse lengths, ADC values, and SPI messages once every x seconds (or milliseconds) to send them in a data stream to my PC. So I'd like to do this all within a Timer A interrupt so I can ensure a constant update rate. 

I know people have suggested using interrupts to assign the value in the corresponding capture compare register to a variable, but since this is all within a timer A interrupt, I'd like to avoid doing so. 

I've used other microcontrollers that have a feature where upon detection of a rising or falling edge, the current value of the counter is saved in a register to be accessed later. This would be ideal so I can avoid using any interrupts besides the overall timer A interrupt (I would access the value in the register within the timer A interrupt). I don't know if this is a feature of the MSP432. If so, can you explain how to do so? Otherwise, I'd like to another way of doing so that isn't too interrupt heavy (because UART transmissions and SPI readings need to have the highest priorities).

I've added my code below to show you what I have so far:

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

void init_clocks(void);
void init_timers(void);

I only included the capture mode configuration for one of the encoders, but the others follow the format.

float q[3] = {0.0, 0.0, 0.0;               // Joint Angular Positions
float q_dot[3] = {0.0, 0.0, 0.0};           // Joint Angular Velocities
static float q_prev[3] = {0.0, 0.0, 0.0};   // Variable to hold previous time step angular position

// Timer to control capture, ADC, and SPI reading updates
const Timer_A_UpModeConfig upConfig_1 =
{
        TIMER_A_CLOCKSOURCE_SMCLK,              // SMCLK frequency = 3 MHz
        TIMER_A_CLOCKSOURCE_DIVIDER_10,         // 3 MHz/ 1 = 300 kHz
        6000,                                  // 6000 * 1 / 300 kHz = 0.02 s (50 kHz) period
        TIMER_A_TAIE_INTERRUPT_DISABLE,         // Disable timer interrupt
        TIMER_A_CCIE_CCR0_INTERRUPT_ENABLE ,    // Enable CCR0 interrupt
        TIMER_A_DO_CLEAR                        // Clear value
};

// q4 (encoder 1) capture mode configuration
const Timer_A_CaptureModeConfig captureModeConfig_q4 =
{
        TIMER_A_CAPTURECOMPARE_REGISTER_1,        // CC Register 1
        TIMER_A_CAPTUREMODE_RISING_AND_FALLING_EDGE,          // Rising Edge
        TIMER_A_CAPTURE_INPUTSELECT_CCIxA,        // CCIxA Input Select (try B)
        TIMER_A_CAPTURE_SYNCHRONOUS,              // Synchronized Capture (try Asynchronous)
        TIMER_A_CAPTURECOMPARE_INTERRUPT_DISABLE,  // Disable interrupt
        TIMER_A_OUTPUTMODE_OUTBITVALUE            // Output bit value
};

{
    WDT_A_holdTimer();              // Stop watchdog timer
    MAP_FPU_enableModule();
    MAP_Interrupt_disableMaster();

    // Initialize Peripherals
    init_clocks();
    init_timers();

    // Start Counters/ISRs
    MAP_Timer_A_startCounter(TIMER_A1_BASE, TIMER_A_UP_MODE);

    MAP_Interrupt_enableSleepOnIsrExit();
    MAP_Interrupt_enableMaster();

    while(1){}
}

// ISR to get magnetic encoder values
void TA1_1_IRQHandler(void){

}

void init_clocks(void){
    // ** Make sure clocks are at desired frequencies
    MAP_CS_setDCOFrequency(24.0E+6); // DCO = 24 MHz
    MAP_CS_initClockSignal(CS_SMCLK, CS_DCOCLK_SELECT, CS_CLOCK_DIVIDER_8); // SMCLK = 3 MHz
}

void init_timers(void){
    // Initialize timer that controls UART transmission and capture, ADC, and SPI updates
    MAP_Timer_A_configureUpMode(TIMER_A1_BASE, &upConfig_1);
    MAP_Interrupt_enableInterrupt(INT_TA1_0);
    // Initialize capture modes
    MAP_Timer_A_initCapture(TIMER_A2_BASE, &captureModeConfig_q4);
    MAP_Timer_A_initCapture(TIMER_A2_BASE, &captureModeConfig_q5);
    MAP_Timer_A_initCapture(TIMER_A2_BASE, &captureModeConfig_q6);
}
-----------------------------------------------------------------------------
I've left the timer 1 ISR blank since I haven't figured out my strategy. That is what I'm hoping to fill out with your answer!
I only included the capture mode configuration for one of the encoders, but the others follow the format. Essentially, every Timer 1 interrupt,...
I would subtract the count of the falling edge from the rising edge and convert that to a time (I have the conversion factor). 

There are a few things I don't understand about the configuration struct:
- Since I'm using both rising and falling edges, does that mean the value in CCR1 is populated with the rising edge count and subsequently, the falling edge count? If that's the case, how could I get the difference if one count value is lost when the other is found?
- The pulses are coming from an external wire. Should the input select be CCIxA or Vcc? I plan on attaching that wire to the TA1.1 pin on the MSP432. 
- Can you explain what OUTPUTMODE_OUTBITVALUE means?

Thanks in advance,
