Part Number:TMS320F28379D

Tool/software: Code Composer Studio

 

Hi Champs,

My customer is using Simulink model (MATLAB).

We encountered  "Error: Import failed for project 'file name' because its meta-data cannot be interpreted. Please contact support."

1: My customer is using Simulink/MatLAB

2: Create "CCS" project folder that based on Simulink model (MATLAB)

3: Try to import this folder to CCSv6.2.0 . CCS error message display "Error: Import failed for project 'file name' because its meta-data cannot be interpreted. Please contact support."  According to Mathworks, Mathwork environment success to import.

4: So, our customer think this is CCS set up issue.

Could you please any CCS setting to fix this error ?

<Environment>

1: Using F28379D Delfino Experimenter Kitを

２: Add  this「Embedded Coder Support for Texas Instruments C2000 Processors version 18.1.2」addon function on the Simulink/MATLAB.

3:  When  execute Simulink model as external mode, this MATLAB/Simulink execute to compile and build automatically using enclosed CCS function and flash MCU

Regards,

Kaz

ADS1220EVM: How to reduce ADS1220 EVM noise

Part Number:ADS1220EVM

Hi,

      Bellow experiment data was perfom in ADS1220 EVM board. The differential input was from AN1-AN2.

We had tested at different voltage reference,sps and pga gain,each test got form 512 samples and pick up 

max/min value form 512 data. Customer need the pga gain bellow 8v/v because there sensor have bias voltage about 200mV

and this voltage is different from each sensor so they could not kill the bias voltage. The conversion speed need 600~1000 sps.

If the noise can reduce third or half they will choose ads1220 in there product. Could you give some advice to reduce the noise.

Whether ADS1220 can satisfied customer need.

LSF0102: Does the device has one-shot?

Part Number:LSF0102

Hi, 

One of my customer is looking for 2 bit bi-directional level translator without one-shot and static power less than 200uA (static power + leakage). All the TXS and TXB family devices has the one-shot implementation. TCA9509 has more sleep current. I could find LSF0102 as the option with less Icc, and the datasheet does not mention about one-shot. But I could not see block diagram in the datasheet. Can you please confirm that the device has no one-shot implementation?  Also can it support arbitration and clock stretching?

Dear TI's expert,

I have a question about RSOC refresh issue as below,

I charge battery to 100%RSOC and monitor Battery Management Studio data by using EV2300 and SMbus then using I2C and bq769X0 Evaluation Software to monitor battery status.

The RSOC data will be changed from 100% to 59%, is this situation normal?

1.EV2300+SMbus before :

2. Monitor Battery Management Studio by EV2300+SMbus after scan bq769X0 Evaluation Software by using EV2300+I2C 

thanks.

Hi TI,

Here are two application:

-- input: 5V  output: 75V/25mA

-- input: 5V  output: 200V/10mA 

1. I have found LM3478 and LM5122, could you help to check if these are good for the request or not, or any better solution for this, thank you.

2. There is a TI design, PMP20183, using LM3481, is it possible to use LM3478 and LM5122 to replace?

Hi Team,

Is it possible to apply 3.3V to SCL, SDA, ADD0 and ALERT when powering off (V+=0V)?
I would like to know if TMP102 could be damaged or not in this case.

I believe it is possible according to the following absolute maximum ratings however would like to confirm just in case.

MSP430FR2433: [Driverlib]How can I cause the DCO to oscillate to 4195200Hz?

September 26, 2018, 3:49 am
$

Part Number:MSP430FR2433

My customers are testing DCO with MSP - EXP 430 FR2433.
They are using driverlib.
However, They would like to oscillate the DCO at 4192500 Hz with driverlib, but the "FLLUNLOCK" bit will be set.
This causes looping at line 274 of cs.c.
Moreover, DCO at this time oscillates unstably.


They use the project example "cs_ex1_DCO 1 MHz SWTrim".

We changed the setting only as follows.

If it is 4 MHz, we confirmed that 4 MHz oscillates properly.

 

"Question"

1. Is this a bug in driverlib? Or are you missing the setting?

2. What should be noted in order to oscillate the 4195200 Hz using the external crystal as the reference clock (XT1)? Give me advice.

Best Regards.

CC2538: Every two resets, join to network fails

September 26, 2018, 3:28 am

Part Number:CC2538

Hello,

Using CC2538, with Z-Stack Mesh v1.0.0 due to compatibility reasons.

I have already a ZC that creates a network and then I connect a ZR. To do this test I have used the GenericApp example of the library.

 

I have used HOLD_AUTO_START to perform a network connection at application level. Moreover I don’t want to use NV network parameters so I set the NV flag to force a new join if the NV_RESTORE is defined. As specified in documentation (Z-Stack Developer’s Guide - SWRA176) NV_RESTORE must be always enabled in a real ZigBee network. So I added these two lines just at the end of the function GenericApp_Init() of GenericApp.c.

 

zgWriteStartupOptions( ZG_STARTUP_SET, (ZCD_STARTOPT_DEFAULT_NETWORK_STATE | ZCD_STARTOPT_DEFAULT_CONFIG_STATE) );

ZDOInitDevice(0);

 

First time, the ZR connects successfully to the network that ZC has created. But when the router is reset, no beacon request is seen neither attempt to reconnect.

If I restart the node again, it perform the connection successfully. And again, if I restart the node, no attempt to reconnect is seen. Therefore, every two resets ZR doesn’t connect to the network.

 

I debug the code and seems that in the function ZDO_StartDevice() from ZDObject.c, NLME_NetworkDiscoveryRequest() returns ZNwkInvalidRequest every two resets.

I don’t know what I am doing wrong, I only want a node that connects not automatically to a network without using the NV network parameters.

 

Anyone could explain me why all this is happening?

 

Thanks.

Melvin.

Hi ,I'm using msp430f5529 with MSP430-GCC-OPENSOURCE on linux,when I try to memset a buf[4096] to 0,like this

#define BUFSIZE 2048
uint8_t buf[BUFSIZE];
int main(void)
{
  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT

  memset(buf,0x00,sizeof(uint8_t)  * BUFSIZE);

the program will stuck before main function.when I debug I found the compiler will automatic memset before main,and if the BUFSIZE is too large(2048 is fine ,but 4096 can't work).

Why?
