Part Number:CC2650EM-4XS-RD

Hello All,

Currently my configuration uses ICALL_STACK0_ADDR as 0x9000.

My application image size has increased and would like to shift the stack image. If i change ICALL_STACK0_ADDR to anything else(say 0xA000). The application and stack images correctly gets loaded in the Flash at their respective configured addresses(stack = 0xA0000) however the Application and stack images doesn't interact.

I have made the linker config settings for the application and stack as below:

Environment :CC26504xs custom board, IAR Workbench version - 7.40.2.8570, TIMAC - 1.5.2, TIRTOS - 2.11.01.09.

Am i missing anything here. 

Please suggest.

Best regards

Naveen

Part Number:CC2650MODA

Hi,

We are developing a product based on the CC2650MODA (both for central and peripheral). While testing we found that sometimes the BLE Central application becomes unresponsive when the wireless connection gets very bad. The only way to get it back up is through a hard reset.

After a bit of investigation, it looks like the BLE stack itself gets stuck in a call to RFCDoorbellSendTo, which is is described as "Send command to doorbell and wait for ack.". So it looks like the Ack is never received. Since I have happily used the BLE stack without delving too much into the details of the implementation and the doorbell mechanism it uses to communicate with the RF core, I'm at a loss as to how to debug this further. What can I do wrong that makes the RF core crash?

If more information is required to analyze this issue, please let me know.

Thanks in advance,

Jeroen

Part Number:DRV8871

HI,

Pulse input up to 200kHz is recommended for fPWM of DRV8871-Q1.
(1) has comments, but I can not understand the contents.

Please tell me the H-Level period and the L-Level period of PWM.

Q1.
If fPWM=200kHz and duty=50%, consider H-Level=2.5μs and L-Level=2.5μs.
16% think that H-Level=2.9us, L-Level=2.1us Is there a problem?
Also
Is 84% in H-Level=4.6us, L-Level=0.4us, is there no problem?

Q2.
"Typical devices require at least 400ns.".......
Although it is written in the comment.
Is 400ns the min period of L=level?

Q3.
Is 800ns min during H=level?

Tool/software: TI-RTOS

hi 

my version:

ccsv7.4

tidriver_msp43x_2_20_00_08

bios_6_46_00_23

I'm still using the EXP_MSP430F5529LP development board to verify SPI communication, Recently , I'm stuck in the SPI_transfer() function. config spi slave mode under TI-RTOS.

target: SPI master sends a byte, spi slave  judge the byte and to continue receiving or sending data.

here is my config

    /* Create I2C for usage */
    SPI_Params_init(&spiB1_slave_Params);
    spiB1_slave_Params.transferMode          = SPI_MODE_BLOCKING;
    spiB1_slave_Params.mode                       = SPI_SLAVE;
    spiB1_slave_Params.dataSize                 = 8;

    spiB1_slave = SPI_open(Board_SPIB1_SLAVE, &spiB1_slave_Params);
    if (spiB1_slave == NULL) {
        System_abort("Error Initializing SPI B1\n");
    }else {
        System_printf("SPI B1 Initialized!\n");
    }
    System_flush();

issue    I use the following two pieces of code for data reception validation

	//code 1
	//disposable recept 3 bytes
        SPI_Transaction spiTransaction;        
		
	spiTransaction.txBuf = NULL;
	spiTransaction.rxBuf = rxBuf;
	spiTransaction.count = 3;

	if (SPI_transfer(spiB1_slave, &spiTransaction) == NULL) {
		System_printf("SPIB1_SendData SPI Bus fault\n");
		System_flush();
	}
	System_printf("%s\r\n",rxBuf);
	System_flush();
	
	
	
	//code 2
	//first recept 1 bytes
        SPI_Transaction spiTransaction;        
		
	spiTransaction.txBuf = NULL;
	spiTransaction.rxBuf = rxBuf;
	spiTransaction.count = 1;

	if (SPI_transfer(spiB1_slave, &spiTransaction) == NULL) {
		System_printf("SPIB1_SendData SPI Bus fault\n");
		System_flush();
	}
	
	//continue recept 2 bytes
	spiTransaction.txBuf = NULL;
	spiTransaction.rxBuf = rxBuf+1;
	spiTransaction.count = 2;

	if (SPI_transfer(spiB1_slave, &spiTransaction) == NULL) {
		System_printf("SPIB1_SendData SPI Bus fault\n");
		System_flush();
	}
	System_printf("%s\r\n",rxBuf);
	System_flush();	

result  

When I using the spi master send three bytes at a time, code 1 receive data is ok,  buf code 1  will block in the second SPI_transfer();

When I using the spi master send three bytes each byte is one second apart,  code 1 2 receive data both is ok.

Why is this problem?

Part Number:LMX2581

Dear Specialists,

My customer is considering LMX2581 and has a question.

I would be grateful if you could advise.

---

Regarding OSCin of LMX 2851, which accepts signals of input level of maximum frequency 900 MHz and 1.7 Vpp.

What kind of device does it intend to supply?

I think the oscillator cannot output such a high level, so I'd like to know why.

---

I appreciate your great help in advance.

Best regards,

Shinichi

Part Number:AM4376

Hi,

In my design I have connected a DSP (master) to McASP0 of the AM4376 (slave). The clock and frame sync are provided to pins L23 (McASP0_ACLKR) resp. K23 (McASP0_FSR) by the DSP. I am, however, unable to get any data out of the processor. I read a post with the same issue where they had solved the problem by using Transmit pins (ACLX and FSX) instead of receive pins.

My question is if my connections are correct and in that case why the setup with CLKR and FSR does not work? Is there something else to be considered?

Attach a part of the schematics for your reference.

Tool/software: TI-RTOS

Hi,

I've implemented a watchdog timer to perform a hard reset after it triggers. The watchdog callback is called and does perform a hard reset but the system is not booting afterwards. 

BLE SDK version 2.2.1

TI_RTOS version 2_20_01_08 (with the watchdog bug patched, interrupt typed changed to WATCH_DOG_TYPE_INT in WatchdogCC26xx.c) 

void multi_role_watchdogCallback(UArg handle)
{
    Watchdog_clear(_watchdogHandle);
    // Perform the equivalent of a PIN Reset (hard reset).
    // The cc26xx system has not been design to handle soft reset.
    // Making a soft reset can make the system unstable.
    // All soft reset needs to be replace by Hard reset.
    
    HAL_SYSTEM_RESET();
}

Watchdog_init();
Watchdog_Params params;

Watchdog_Params_init(&params);
params.resetMode   = Watchdog_RESET_OFF;
params.callbackFxn = multi_role_watchdogCallback;
params.debugStallMode = Watchdog_DEBUG_STALL_ON;
_watchdogHandle = Watchdog_open(CC2650_WATCHDOG0, &params);
uint32_t watchdogTicks = Watchdog_convertMsToTicks(_watchdogHandle, 15000);
Watchdog_setReload(_watchdogHandle, watchdogTicks);

Part Number:TMS320F28379D

Tool/software: Code Composer Studio

When loading our program into the microcontoller, we are limited at 8kB of RAM beyond, the software informs us an error loading program due to memory.

error #10099-D: program will not fit into available memory.

We realized the test by putting an empty program and coding an array of 4096 integers either (4096 * 16bits = 65536 bits ie 8192 bytes or 8kB).

How can we change this threshold because we don't use whole memory.

In Which function do we must take action to change this threshold ?

Do we must take action of the memory map directly ? Is there a risk to modify memory adress in a file memory map ?

Best regards.

Part Number:TIOL111

Hi,

my name is Marion, I am currently looking into the TIOL111 to prepare for a meeting.

It is hard to find a standardized power consumption what a slave IO-Link device is allowed to take from the point to point 24 V level.

What if a customer feeds his device only through this voltage level?

Is our part appropriate then?

I found those calculations in the datasheet:

but I understand, that it is only for the given case. Why do you calculate 250mA, if the current limit is 200mA?

Kind regards, Marion

Part Number:AWR1443BOOST

Hello,

I am using the Evaluation module AWR 1443 and we would like to record dat a through the mmwave Demo Visualizer. We are able to record a .dat file, but the format is completely unknown for us and for the matlab file capture_demo.m.

We are using the SDK version mmwave_sdk_01_01_00_02. We are able to savet his version in the flash memory, but we are not able to uncode the final .dat file.

Alternatively, I have followed the TI guide "ADC Data Capture using Capture Demo and CCS Memory Browser IWR14xx/AWR14xx example" in order to capture the data using the Code Composer Studio 8.0. This option works perfectly but it is a tedious process and it is suitable to capture one measurement. I would like to automate the process in order to capture measurements every 2 minutes and save all these measurements in an only .dat file. Since the mmwave Demo Visualizer has the option to record data, maybe it is the best choice to do this. The problem is that the final format is coded.

Could anybody help me?

 Best regards,

 Carlos.

Part Number:TMS320F28335

Tool/software: TI C/C++ Compiler

Hello everyone,

I just inherited a project for the TMS320F28335.
The project is supposed to be a custom kernel to program Flash of the DSP over SCI.

The people who worked on the project always flashed the custom kernel via JTAG and afterwards send the "real" programm over SCI, that wokred quite well.
But if  the developement phase will be over some day the users of the kernel won't have access to the JTAG port and can only programm via the SCI-Interface.
So the kernel must only operate on the DSPs RAM.

Here is my question,
can I somehow get information about which code parts are stored in RAM and which will be stored in the Flash so I can move the kernel step by step from flash into RAM.

Is it possible to generate a warning, Error or something else that shows that the project will be using flash memory.

Regards,

Marcel Kummer.

Hello,

Does there exist example code for restoration TLV structure in MSP430F249? Customer erased TLV structure in his chips and now he wants to restore original TLV.

Thank you.

Part Number:DS90UB954-Q1

Hi, E2E members

We are planing to use some sensers that CSI-2 data rate are 184 ~ 506Mbps.

- Can we use the following setting DS90UB953 and DS90UB954?
DS90UB953-Q1 input : 184Mbps x 1 lane →　DS90UB954-Q1 output : 800Mbps x 1 lane
DS90UB953-Q1 input : 506Mbps x 1 lane →　DS90UB954-Q1 output : 800Mbps x 1 lane

1) Can the DS90UB954-Q1 use the setting of CSI-2 data rate of 800Mbps, regardless of CSI-2 data rate of DS90UB953-Q1 side?

2) Dose DS90UB954-Q1 have to change CSI-2 data rate of 400Mbps, if DS90UB953-Q1 input data rate below the 400Mbps?

Regards,
Nao

Part Number:MSP430FR2433

Hello.

I would like to keep MSP430FR2433 in LPM4.5 keeping state of I/O output  for 2 to 3 years.

Is the above possible?
Is there anything to watch out for?

I am worried that I/O status will change or wakeup will not happen by I/O because the period of LPM4.5 is very long.

Do you need to monitor that MSP430 is functional with watch dog timer?

Regards,

Part Number:ULN2003A

When I use ULN2803A to drive the motor, I only need 5V to drive the motor. The current is 300~250mA.However, when I used UNL2003A, it required 5.8V to drive the motor, and the current was the same 300~250mA.Why is that?

Part Number:F28M35H52C

Tool/software: Code Composer Studio

The precondition is : encoder is 2500 lines and MCU is F28M35H52C1.

We use qep to test a pmsm motor,we find the speed accuracy when low  is very bad : +/-20rpm for 50rpm.

So we want to know what is the low speed accuracy for this IC using qep? do you have example code or inner block for qep?

Thanks for your help

Part Number:ADS1299

Hello TI engineers! I have recently encountered several technical problems with TI's chips. TI's evaluation board is to directly acquire EEG signals without an external amplifier circuit, but the EEG signal is a very weak signal, and the voltage amplitude is only uV level. The PGA of the chip has a maximum gain of 24, and if the EEG signal is 20uV, the amplitude after amplification is 20*24=480uV, so the voltage captured by the ADC is less than 1mV. My question is: Can EEG signals be  captured without an external amplifier circuit? Is an external amplifier circuit necessary? Do you have any suggestions? thank you very much!
