Part Number: LAUNCHXL-F28379D

Hello everyone,

I am trying to transmit data over CAN. I am sharing block diagram below.

But obtained messages are as it seems in the following figure.

Why I am not be able to read related data. Why am I getting error ? Why cant I see sent message .

Thanks.


TMDSECATCNCD379D: Purpose of padding in PDO mapping object

Part Number: TMDSECATCNCD379D

I am trying to generate SSC code from SSC tool. I am using TI TMDSECATCNCD379D (and its SSC tool patch) and SSC tool 5.11. The generation is fine but I found the code genreated have padding for both PDO mapping object. e.g.

OBJCONST TSDOINFOENTRYDESC    OBJMEM asEntryDesc0x1601[] = {
{ DEFTYPE_UNSIGNED8 , 0x8 , ACCESS_READ },
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }, /* Subindex1 - map control word */
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }, /* Subindex2 - map target position */
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }}; /* Subindex3 - add 16bit padding to get an 32Bit object/process data structure */

while there is none in TI TMDSECATCNCD379D own demo application:

OBJCONST TSDOINFOENTRYDESC    OBJMEM asEntryDesc0x1601[] = {
{ DEFTYPE_UNSIGNED8 , 0x8 , ACCESS_READ },
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }, /* Subindex1 - Reference to 0x7010.1 */
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }, /* Subindex2 - Reference to 0x7012.1 */
{ DEFTYPE_UNSIGNED32 , 0x20 , ACCESS_READ }}; /* Subindex3 - Reference to 0x7014.1 */

Both seems working fine (at least communication normal) but I would like to understand more to avoid any future problem.

Thanks for reading. Any reply is appreciated.

Part Number: IWR1443BOOST

Hi,

I couldn't find a .dsn or .opj file compatible for the "IWR1443BOOST-Rev-A.brd" I found in all your documents on your website.

Is there any possibility for you to guide me into that specific document or send it to me, because I can't seem to find it in your website.

Thank you,

Mijael. 

BQ24079: Bulk capacitance limit on OUT pin

Part Number: BQ24079

Hello,

It is recommended to bypass OUT with 10 to 47 uF ceramic capacitor (page 7 in the BQ24079 datasheet, OUT pin).

Is there any capacitance limit for a bulk capacitor on OUT pin? Is 47 uF a maximum limited by internal regulator’s stability region? 

Thanks

Part Number: MSP430F5419A

Hello ,

   I'm facing a problem with changing baud rate of an UART from 9600 to 115200 with frequency of an 1MHZ 

i have written the below code 

UCA0CTL1 |= UCSWRST; 
UCA0CTL1 |= UCSSEL_2;

UCA0BR0 = 8; // 1MHz 115200 

UCA0BR1 = 0; // 1MHz 115200
// UCA1BR0 = 0; //1MHZ 115200
// UCA1BR1 = 0; //1MHZ 115200
UCA0MCTL = UCBRS_0 + UCBRF_13 + UCOS16; // Modln UCBRSx=0, UCBRFx=0,
UCA0CTL1 &= ~UCSWRST; // **Initialize USCI state machine**
__no_operation();
UCA0IE |= UCTXIE;
UCA0IE |= UCRXIE;

ADS127L01EVM: Is it possible reading "32 bit SPI data output" from the ADC to MCU - TM4C1294XL

$

Part Number: ADS127L01EVM

Dear Sirs,

With the board I used ADS127L01EVM, I am measuring the analog differential voltage signal from a gyro. I want to send my digital data to another MCU (TM4C1294XL), but the receiving side has a 16-bit RX FIFO. Therefore, it can not read 32-bit SPI data from the ADS127L01EVM.

While converting 24 bit analog Gyro data to digital data, I want to send it countinously to a proper MCU for filtering or some math operations.  MCU will process and send the data by using CAN or another communication channel.

,

Measured signals on oscilloscope screen where the signal designations are as follows:

Pink: DOUT
Yellow: CLK
Blue: FSYNC
Mode: Frame-sync master mode
WB2 , OSR 256

ADS127L01EVM works fine but the SPI output is 32 bit. My MCU has max. of 16 bit RX FIFO.

We opened a question with the Other microcontrollers forum. I have confirmed that the two cards are incompatible.

Would you have any recommended MCUs compatible to work with ADS127L01EVM to recieve 32-bit data from the ADC we are currently using?


Do you recommend a compatible MCU for ADS127L01EVM ? Because the ADC has 32 bit SPI transaction.
You may advice me to use another ADC board compatible with my TM4C1294XL.

Riza

Hi Team,

A customer designs his own board with CC3220SF. He has set the SOP to 000, and connected RST/TMS/TCK/TDI/TDO from CC3220 launchpad to custom board. But both CCS and Uniflash can not detect his board. He also tested with Target Configuration in CCS and it showed succeeded. Please check the following figures:

Part Number: TLIN1029-Q1

Hello,

My customer observes varying rise/fall time on LIN bus. I guess it is because of the difference between master and slave termination. But the slope control is suspicious too.

AM5718: DDR3 bit swapping

Part Number: AM5718

I hand previously raised  a query in this regards

based on this I happen to swap bit 0, bit 8, bit 16 & bit 24

I happen to come across this thread

e2e.ti.com/.../655828 and Application note www.ti.com/.../spraci2a.pdf

""Databit swappingis allowedto simplifyrouting,providedthe bits swappedare withinthe samebytegroup.However,the primebit, the lowestnumberedbit in eachbyte,mustbe connectedto thecorrespondingbit on the SDRAMwithoutswapping.Thatis, bit 0, bit 8, bit16,and so forth.Also,the DM and DQS bits mustnot be swapped.""

Is it mandatory to maintain bit0 , bit8 , bit16, bit24 positions as in evaluation board?? or these bits can be subjected to swapping within their byte lanes. pls confirm.

Regards

Hi,

  I'm using Code Composer Studio version 9.2.0.00013 and am trying to install an older version of the compiler via the 'Install New Software' option. When I select the 'Code Generation Tools Update' I get an error that the website software-dl.ti.com/.../p2win32 cannot be reached. 

When trying to access this directly I get a message saying that the website is down for maintenance. Any ideas when this will be back up?

ISO7710: About datasheet

Part Number: ISO7710

Hello support team,

I have a question about the datasheet of ISO7710.
Our customer pointed out it.

In Figure 18 on page 19, "INPUT" and "VCC" are shorted.
I think "INPUT" should be connected to pin 2.
I think it is a typo, how is it?
I think that the same part is wrong in the datasheet of ISO7710-Q1 too.

Sincerely,
M. Tachibana

CC2650MODA: no flash/update possible

Part Number: CC2650MODA

Hi all,

customer has issues with some CC2650 devices.
Some of them can no longer be flashed / updated (Segger J-Flash V6.50b) via JLink or JFlash-Programm.

Is it possible that the CC2650 can only be flashed a few times?  are there some known situations, where the flash /SBL-Bootloader can be destroyed?

See attached the screenshot of the JFlash-Programm (also occurs with the IAR) ---> there is also no communication via UART



Thanks in advance!

CC1310: Problem in running wMBus

Part Number: CC1310

I'm trying to run a simple test to check wMBus protocol.

To do so, I have CC1310 LaunchPad, and I installed the "wmbus_cc13x0_rtos_2_0_0.exe"

Then I loaded the Serial_CC13xx_Collector_T2.hex on CC1310 LaunchPad, and connected it to PC to test with.

I got the project of serial library swra466b/sblAppEx_1_03_00_00. When I run it and open the port of LaunchPad's UART I got an error and couldn't have wMBus protocol running!

The goal of my test is to check the protocol and test it, I have a wMBus water meter and I'll use the CC1310 LaunchPad as collector to read the meter, commuicating with CC1310 LaunchPad will be through the serial UART using sblAppEx_1_03_00_00, am I right?

Can you please help?

LAUNCHXL-F280049C: instaspin, LAB_06_torque control , negative Iq_ref

Part Number: LAUNCHXL-F280049C

Hi,

I trying to use insaspin to control motor.

DEVICE : LAUNCHXL-280049C + BOOSTXL-DRV8320RS

I followed the procedure in th lab_06.

And I feel the torque of motor by changing IdqSet_A[1] which means Iq_ref.

But, when negative value is assigned to IdqSet_A[1], the motor doesn't work well.

What should I do for negative torque?

Thank you
