Part Number: LMX2571
Hi Team,
Customer want to generate 48MHz and 64MHz clock with very low power consumption and good phase noise. They have seen LMK03318 and CDCE913 and now move to LMX257x.
For LMX2572 and LMX2571, how about your comments on the phase stability and phase noise performance @40MHz ~ 150MHz output frequency? Any test report related with that?
Thank you!

Hi,
I am trying to apply the echo example code to Pin 2.5, Pin 2.6, I already have it working with the default Pin 6.0 and Pin 6.1, however, I cant get it working with the other pins. This is my code:
int main(void)

WDTCTL = WDTPW | WDTHOLD; // Stop Watchdog
// Configure GPIO
P6SEL1 &= ~(BIT0 | BIT1);
P6SEL0 |= (BIT0 | BIT1); // USCI_A3 UART operation
P2SEL1 &= ~(BIT5 | BIT6);
P2SEL0 |= (BIT5 | BIT6); // USCI_A1 UART operation
// Disable the GPIO power-on default high-impedance mode to activate
// previously configured port settings
PM5CTL0 &= ~LOCKLPM5;
// Startup clock system with max DCO setting ~8MHz
CSCTL0_H = CSKEY_H; // Unlock CS registers
CSCTL1 = DCOFSEL_3 | DCORSEL; // Set DCO to 8MHz
CSCTL2 = SELA__VLOCLK | SELS__DCOCLK | SELM__DCOCLK;
CSCTL3 = DIVA__1 | DIVS__1 | DIVM__1; // Set all dividers
CSCTL0_H = 0; // Lock CS registers
// Configure USCI_A3 for UART mode
UCA3CTLW0 = UCSWRST; // Put eUSCI in reset
UCA3CTLW0 |= UCSSEL__SMCLK; // CLK = SMCLK

Part Number: BQ27742-G1
Hello,
I'm looking for an charger IC which provides my system side with 3.3V (max 0.5A needed).
Device should be charged from single Input USB/ High Voltage Adapters, Input Voltage 5 - 13.5-V.
Battery INR18650 (or similar type):
LiNiCoAlO2, 3300mAh, max charge current 2000mA
Fuel Gauge and Protection(recommended from last post):
Single Cell Li-Ion Battery Fuel Gauge With Integrated Protection bq27742-G1
I cant find any charger IC which has an system output with 3.3V for powering my Microcontroller.
I want to use a I2C interface to communicate between Hosts an IC's.
Do I need to use a non-power path charger (linear regulator or switching converter) with an external buck converter instead? (For example TPS63050)
Would be happy if someone can give me an advice.
Greetings

When I use the following field in projectSpec:
linkerCommandFile="../TI_Files/cmd/F2812_EzDSP_RAM_lnk.cmd"
The field appears to be ignored and instead I get a message saying:
NOTE: Linker command file not specified - defaulting to '2812_RAM_lnk.cmd'.
When I try to create a project using a Makefile and I include the following:
-ccs.cmd "../../common/cmd/F2812_EzDSP_RAM_lnk.cmd" \
It appears that the linker command file is not listed in the .cproject file that is created from the Makefile.
What am I doing wrong in trying to specify my linker command file?

To test the managing the wMBus protocol with CC1310, I loaded the Collector hex application of wMBus to CC1310 LaunchPad (wmbus-cc13xx-rtos-2.0.0/hex/CC13xx_RTOS/Serial_CC13xx_Collector_T2.hex).
Then I checked the STACKFORCE Serial Protocol to test sending some packets, I found something confusing:
In someplaces, it's decleared that the packet format is:
+--------------------+-----------------+-- - - --+--------------+ | SYNC BYTE [1 Byte] | LENGTH [2 Byte] | PAYLOAD | CRC [2 Byte] | +--------------------+-----------------+-- - - --+--------------+
While in other places it's decleared that the packet format is:
+--------------------+-----------------+--------------------------+-- - - --+--------------+ | SYNC BYTE [1 Byte] | LENGTH [2 Byte] | INVERTED LENGTH [2 Byte] | PAYLOAD | CRC [2 Byte] | +--------------------+-----------------+--------------------------+-- - - --+--------------+
In the document "Wireless M-Bus Serial Library for Metering Applications" (slaa831.pdf)
While in the documentation of "wmbus_cc13x0_rtos_2_0_0":
Can you please tell me which one is used ?
I tested the sending following packets to the CC1310 LP after I loaded "wmbus-cc13xx-rtos-2.0.0/hex/CC13xx_RTOS/Serial_CC13xx_Collector_T2.hex" on it,
But I got no response!!
First Packet:
A5 00 01 0A 53 78
Second Packet:
A5 00 01 FF FE 01 C2 9A
Can you please help?
I couldn't test wmbus with CC1310!

One of our products uses a 2407A dsp. We are having to do some support and enhancements. I am trying to build this in CCS3.3 under windows 10, as this appears to be the last CCS version to support the 2407A. The code is existing and working code original built with older tools. It should build. It seems to compile fine. But when it tries to link it I get a an error “can not open config.obj for input” with nothing else. The file it seems to be complaining about is present, so it should be able to find it especially since the CCS3.3 .lkf file has the correct path name correct to the file location. I am suspecting this is a more general error with specific information is missing, so I am having trouble finding the problem.
I am running CCS3.3 under windows 10 (64 bit) in XP compatibility mode SP3. It will not function without this.
As confidence builder I am trying to build another working project (2812) that did use CCS3.3 (now under windows 10). I am also having problems with this as I cannot selection the bios in the component manager. It shows it as the correct version, I check the box but will not show selected when reopening. The code will not build as It cannot find the bios files.
One of my theories is might be a permissions issue, I have tried changing permissions on the CCS3.3 folder and working folders. No change in behavior.
Searching the web and TI E2e forms have not produced any solutions. Needing help with this.
Part Number: AWR1642BOOST
Dear Technical Support,
I am playing with the "RangeDoppler heatmap" visualization of the mmWave Demo Visualizer an I have 2 questions:
I set the frame rate to be 2fps which leads to a periodicity of 500ms for 1 frame: which frame is displayed on the screen? Is it frame #1, frame#2, frame#1, frame#2 each 500ms refreshing step?
I thank you for your support.
Best regards.

Part Number: TCA9555
Hi Team,
I'd like to know about the power-on-glitch of the TCA9554 and TCA9555. The TCA9554 states that "No Glitch at Power Up" but similar description does not appear in the TCA9555 datasheet. Is that because we added some "glitch-suppressing" circuitry inside TCA9554 but not in the TCA9555?
How does the power-up glitch look like for the TCA9555? And is there any way to suppress the glitch?
Thanks!

Part Number: LMX2491
Hello Team,
I do see that the LMX2491 evaluation board is not available for purchase. Only the LMX2492 is available.
What are the options to test the LMX2491?
If the LMX2492 would be the only options, how can I compare the results?
Would the performance up to 6GHz the same?
Thanks,

Hi all, I am having 2 problems.
1- Keysight 34401a dmm keeps getting -410 error.
Pretty much the same, the only difference is that I use PGA309, not 308: 
2- Temperature setting changes by itself. It asks for 50C in the middle of the calibration, and eventually it becomes 100C.
Apparently TI developed a new version software. And so, please send me a download link
Thanks

Hi If i created task with default priority which is turned out to be 1 i can see this task is run, but I specify priority of the same task 6 it is not running.
I is created fro tcp recv task with priority 6 , id this newly created task have same priority it does not have a chance to run.
It looks like task with lower priority number have chance to run.
Is priority 1 is gretaer that 6 ?
If there are the way for me to create tasks which have same priority ( round robin ) with minimum time slice to run.
Part Number: DLPDLCR2010EVM
Hello,
For our product - DLPDLCR2010EVM is used.
Lightcrafter is upgraded to the latest FW. Input video stream frame rate is equal to 240Hz.
In designed product image can be shown 1/4 of 240HZ frame rate.
Content - black image - black image - black image. (this sequence of images is repeated)
If:
1. test image is color spectrum;
2. Lightcrafter or head is moved;
Ccolor bending can be seen.
Question - 240Hz refresh rate means, that every time full image content is updated or some portion of the frame?
Question - what is the maximum full content refresh rate?
Thanks in advance,

Hello,
Sorry if this is an obvious question. Does each Concerto device have a unique MAC address programmed by TI?
The technical reference manual talks about how to change the eMAC individual address registers, and it talks about the default ID stored in OTP, but I don't understand. If I don't change the address myself, will each device already have a unique address or not?
Thanks,
Joel

Hi,
I have a problem with UARTprintf:
UARTprintf("Value is %d\n",2) prints Value is 2
but
UARTprintf("Value is %d\n",2.1) prints Value is 760
In fact for any decimal number it is always wrong. Am I misunderstanding the %d format?
Thanks

All,
How do I get the actual temperature from the DAStatus2 register. TRM shows units of 0.1K , do I just multiple the AAaa by 0.1K and subtract 273 to get Celsius.
When I do that the numbers don't seem correct.
Thanks,

I'll keep asking, last time in May 2019:
what about narrow band support (12.5kHz CHBW) in CC13x2?
TI also keeps telling 'soon, on the road', but is it just work to do or do you have silicium/firmware issues?
And: when will 434MHz be officially supported?
thx.

Hi,
I generated HRPWM on the controller successfully, now I want to change the frequency, duty etc of the pwm in the run time. I am basically looking for a way to send these values from my computer to the controller and have a function triggered that adjust the register values accordingly. I hope you guys can help me with that.
Thanks
