Dear All,

We are trying to design the tunable band pass filter like a below PoleZero's product.

The design spec is as follows.

- Frequency range: 1.5MHz to 30MHz

- 3dB bandwidth: fc +/-3%

- Attenuation: 33dB@fc +/-10%

Could you recommend this solution and opamp application for the tunable BPF?

[PoleZero - tunable filter - band pass filter - NANO ERF]

Part Number:CC2640R2F

Hello

I have to change the device name of my eddystone beacon on the MEB project. I tried the API uble_setParameter but this did not change the name. As of the now there is no name appearing on any of the detection

apps for the device.

When I checked for the simple broadcaster code I found that they have used a GAP Role command for the same. However, GAP roles are not available in MEB.

Can anyone help with this?

BQ25703A: charging battery with 1A (fast mode)

Part Number:BQ25703A

Hi,


I am trying to charge a battery with 3 cells that has a max value ~ 4.8V with a current of 1A.

When I visualize the power supply I see that all is well (the current injected to the bq25703a is ~ 1A) but when I consulted the registers: ChargerStatus (21 / 20h) and ADCIBAT (29 / 28h) I noticed that the current is set at 384 mA and the charger is in pre-charge.

How can I configure the BQ25703a to work in fast mode with a current of 1A?

CCS/MSP432P4011: TI Drivers Power_init() don't return

Part Number:MSP432P4011

Tool/software: Code Composer Studio

Hello,

I try to make the simplelink WiFi plug-in to work withMSP432P4011 and CC3120 in a non-OS environment. It works with the MSP-EXP432P401R Development Kit but on my platform with MSP432P4011 it's a nightmare. The first problem encountered is at the initialization of TI drivers: Power_init() doesn't return.

Here is my (simplified) main function:

int main(void) {
	// Stop watchdog timer
	WDT_A_holdTimer();
	Power_init();
	while(1);
}

And the structure to configure the Power Driver:

const PowerMSP432_ConfigV1 PowerMSP432_config = {
    .policyInitFxn = &PowerMSP432_initPolicy,
    .policyFxn = &PowerMSP432_sleepPolicy,
    .initialPerfLevel = 2,
    .enablePolicy = true,
    .enablePerf = true,
    .enableParking = true
};

If I step into Power_init() in debug mode, the problem occurs at line 1639 in initPerfControl(), in PowerMSP432.c file:

            SET_WAIT_STATES(BANK0, perfNew.flashWaitStates);


I can not display the value of perfNew.flashWaitStates (identifier not found) and I can't step into the SET_WAIT_STATES() function.

Right after this line the program jumps in Default_Handler().

Please help.

NB: simplelink_msp432p4_sdk_2_30_00_14 and simplelink_sdk_wifi_plugin_1_60_00_07 are installed and I use the latest CCS 8.2.

DS125DF410: Input Impedance Tolerance/Variation

Part Number:DS125DF410

Hi Team,

Our customer is asking for the Input Impedance Tolerance for DS125DF410. They seem to have faced impedance trouble in the past using other device.

I can find the input impedance information in the datasheet, however, there is only typical information.

I believe these are not characterized.

Would it be possible to share us the MIN/MAX desige target information ?

If you have any other data which could be shared, it would be greatly appreciated.

CC3220SF-LAUNCHXL: issue when running i2ctmp006 (freertos) driver example

Part Number:CC3220SF-LAUNCHXL

With CC3220SF-LP, there was an issue with running the "i2ctmp006" driver example.

There was no problem when running the demo with TI-RTOS, "i2ctmp006_CC3220SF_LAUNCHXL_tirtos_ccs" and "i2ctmp006_CC3220SF_LAUNCHXL_tirtos_gcc".

However, when running with freeRTOS (i2ctmp006_CC3220SF_LAUNCHXL_freertos_ccs and i2ctmp006_CC3220SF_LAUNCHXL_freertos_gcc), there was no console output message.

So, can you check why there was no console output message with i2ctmp006 demo with freeRTOS, while it worked well with TI-RTOS?

Thanks and regards,

Hayden

hi, i drive our motor with drv10987

my motor parameters

rph=1.552

kt=13

3 phase bldc motor with 10 poles.

the motor work in 24v.

the drv is getting 24v.

this is my configuration:

unsigned char buf_conf5[] = {DRV10987Q_CONFIG1_Reg , 0x04 , 0x4A}; 

unsigned char buf_conf10[] = {DRV10987Q_CONFIG2_Reg , 0x0F , 0x3B};

unsigned char buf_conf11[] = {DRV10987Q_CONFIG3_Reg , 0xCB , 0x86};

unsigned char buf_conf12[] = {DRV10987Q_CONFIG4_Reg , 0x23 , 0x67};

unsigned char buf_conf13[] = {DRV10987Q_CONFIG5_Reg , 0x3B , 0x0D};

unsigned char buf_conf14[] = {DRV10987Q_CONFIG6_Reg , 0x79 , 0x63};

unsigned char buf_conf15[] = {DRV10987Q_CONFIG7_Reg , 0x27 , 0x67};

the motor is running. but, the drv is warming up a lot and when i start the motor sometimes it takes couple of tries before the motor start working.

can you see something wrong in my configuration?

thank you,

Part Number:IWR1443BOOST

Tool/software: Code Composer Studio

Hi 

I would test CAN communication with IWR1443BOOST.

I read chapter 2.4.3 of IWR1443BOOST Evaluation Module mmWave Sensing Solution.

I have an IWR1443BOOST Rev.A. but I have PCB file of IWR1443BOOST Rev.B.

I have the CAN test source in this folder : C:\ti\mmwave_sdk_01_02_00_05\packages\ti\drivers\can\test

The doucument, IWR1443BOOST Evaluation Module mmWave Sensing Solution describes about Rev.A.

I have a question.

The CAN part between Rev.A and Rev.B is different.

Can the source be used to both Rev.A and Rev.B?

If the source cannot be used to Rev.A or Rev.B.

could you let me know the sample code to be able to use to both board.

Hi Team,

May I have the passive filter circuit of PCM4104 analog output? We know the datasheet recommend a 2nd-order Butterworth low-pass filter circuit with a -3dB corner frequency from 50kHz to 180kHz, but that will make high cost pressure for us. So we want to use passive filter at here, please help to recommend suitable circuit, thanks.

Good morning,

I use msp430fr6922 with CCS 7.

I have problem with optimization - It is cut "if", I attached screens with code and disassembly.

If I set optimization to off(OPToff), code work fine.

If I set whole program opt to 0(OPTeveryto0), "while and if" are cut away.

If I set whole program opt to 1 (OPTeveryt1), "if" are cut away.

How shall I set optimization to work fine?

Thank you to response

Dear sir,

We are using MSP430FR5959 for our prroject. Our instrument is multichannel analyzer with one master and
4 slave unit(data logger). All board uses MSP430 chip.

We are using code composer studio( Version: 8.1.0.00011 ) for our softare development and programming.


During course of our development cycle we observed follwing problems in hardware.
1) After completing of software , we kept 5 instruments under observation for coninuous 8 hours a day.
We observed that after about ten days our instrument it fail to work after power on. We doubted Master MCU
board. We tested it.
We found supply voltage 3.3 to MCU Vcc pin-4/ DGND(pin 33) were o.k.(3.3 VDC). We suspect MCU chip
failure. We reprogrammed the MSP chip and our instrument started working. The reason for failure was
not known.
This failure can again occur. So please guide us.
During development cycle this problem has occured many times but we were suspecting software bug.
But we also obsevre that out of 5 instrument only 2 are giving this problem. Other 3 are working non stop.

LM27313: What happens to output if the feedback resistor is broken

Part Number:LM27313

Hi

I'm using the LM27313 boost converter to drive some LEDs.  My boss has asked the question.  What happens if one of the feedback resistors is not fitted.

If the bottom resistor (between FB and ground) is missing then (I think) the switcher will not switch and the output will track the input voltage (less diode drop)

However what i am not sure about is what happens if the top resistor (between the output voltage and the FB pin) is missing.  Theoretically i'd get infinite output voltage but that isn't going to happen.

Any help appreciated.

Part Number:LAUNCHXL-F28379D

Tool/software: Code Composer Studio

I have loaded my program (program generates PWMs) to flash following the process bellow:

e2e.ti.com/.../385578

like this:

(a) controlcard SW1 is in Position 11 (Mode 3 - "Get Mode") .(question: is position 11 means switches 1 and 2 )

(b) File "Codestartbranch.asm" is part of the project.

(c) the correct linker command file is uesd for linking (2837x_FLASH_lnk_cpu1.cmd) (here i used the linker file in the Device_support folder....should i modify it, if yes how !? )

After - reopwering the board the code is executed from FLASH fine but after i modified my code nothing happens and then pins output nothing and reset botton doesn't work.

after that i tried to run the code with emulator by changing the .cmd file to 2837xD_RAM_lnk_cpu1.cmd and "set active --> Debug" but nothing happens, basically i couldn't run my code on either RAM or FLASH.

could you please advice me how to run my codes on RAM again !?

Thank you in advance.
