TLV5630: TLV5630 12 bit

Part Number:TLV5630

Hello All,

I am trying to send some data from Tms320f28335 dsp to TLV5630 DAC via SPI. I am sending the correct signal to the Dac. I have checked the MOSI, Sclk , FS Pins and they are supposed to act as they should be. Now, I have set var1 ( in code below) from data sheet to obtain my analog data in channel B, but i am getting my data on channel C. Only when i give 0x0000 only then I get actual data on channel A. Otherwise I get right data in wrong channels. Can anyone tell me , what mistake i am making in selecting channels? I am given my initialization  and my methodology below. 

daco = (vref*5); // some sinusoidal data points

var1 = 0x1000;

sdata1 = var1|daco;

void spi_init()
{
SpiaRegs.SPICCR.all =0x000F; // Reset on, rising edge, 16-bit char bits
SpiaRegs.SPICTL.all =0x0006; // Enable master mode, normal phase,
// enable talk, and SPI int disabled.
SpiaRegs.SPIBRR =0x0014;
SpiaRegs.SPICCR.all =0x009F; // Relinquish SPI from Reset
SpiaRegs.SPIPRI.bit.FREE = 1; // Set so breakpoints don't disturb xmission


}

void spi_fifo_init()
{
// Initialize SPI FIFO registers
SpiaRegs.SPIFFTX.all=0xE040;
SpiaRegs.SPIFFRX.all=0x204f;
SpiaRegs.SPIFFCT.all=0x0;
}

void spi_xmit1(Uint16 a)
{
SpiaRegs.SPITXBUF=a;
l1=1;
l1=2;
l2=l1/2;

GpioDataRegs.GPASET.bit.GPIO30 = 1;

l2=1;
l2=2;
GpioDataRegs.GPACLEAR.bit.GPIO30 = 1;

Dear Sir/Madam,

I cannot seem to find a Windows-10 USB driver for the ADS1292R interface eval board. Can you assist?

If there is an alternative method of interrogating the ADS1292R please advise also.

INA270A-Q1: the Max Full Range Offset +- 3mV is applied at the fixed Gain = 14 ?

Part Number:INA270A-Q1

Hi Team

may I get your quick response ?

INA270A-Q1 has Max Full Range Offset = +- 3mV and Gain = 14[V/V].

customer wants to know the max offset at the fixed Gain = 14[V/V].

the Max +- 3mV offset is applied at Gain = 14[V/V] ?

or I has to calculate Max +- 42mV offset by (3mV x 14) ?  

I believe INA270(Gain 14) and INA271(Gain 20) have the fixed gain respectively,

so that the Max full range offset is applied at the fixed gain,

but I need BU's confirm.

Part Number:TMS320DM368

Hello,
My customer is dveloping DM368 but they don't use YOUT[7:0].
Those pins become "Input" when reset and there are no IPU/IPDs.

Should they put PU or PD outside of YOUT[7:0]?
If so, are there recomend value of PU/PD register ?

Hi

My Customer has question.

[Table 4. Matrix of Output Capacitor and Inductor Combinations] recommend 1uH, 1.5uH, 2.2uH.

Customer can only use 1 uH or 2.2 uH because of the availability of Inductor.

Is it OK to use 1uH or 2.2uH with the following spec?
I think that either way is OK, but please comment if there are any concerns.

■SPEC

VIN=3.0~3.6V

Vout=3.8V

Iout=0.5A

Cout=20uF

TCI6638K2K: Errata Clarification:

Part Number:TCI6638K2K

  1. In “Literature Number: SPRZ401F”, Table 4. Silicon Revision, 3.1 is mentioned as the applicable revision. But in detailed explanation, Revision(s) Affected: 3.1 is not mentioned. Is it a typo and still applicable for 3.1?

  1. In Usage Note 7, in workaround, it is mentioned that,

    • On PG 1.0 silicon, TI recommends that both AVS rails must be tied together.
    • On PG 1.1 silicon, these two rails are tied together internally

So, we assume, from 1.1 on wards (even for 2.0,3.0 & 3.1), it’s taken care internally. Please confirm.

Dear,

We are continuously working on AM4378 based board with sitara linux. Now i want to  make java (GUI application) work in sitara linux. Since java is not included in the SDK, I  tried to build sdk with X11 from SDK source (4.02.00.09). I referred below web guidelines to build sdk with x11 from sdk source file.

 It gives error while building. please find attached terminal error report

.(Please visit the site to view this file)

I run below command to build sdk with X11.

git clone git://arago-project.org/git/projects/oe-layersetup.git tisdk
cd /home/futura/tisdk/
./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-04.01.00.06-x11-config.txt

cd build/

. conf/setenv

MACHINE=am437x-evm bitbake arago-core-tisdk-image

Our ultimate aim is to make java work in sitara linux. I installed utilities like makeinfo,gawk,chrpath, etc.

Kindly provide the way how to make java work in sitara linux?

How do i solve the above attached error while building sdk with X11?

Hi, I am planning to use TRF372017 IQ modulator to generate 4.5 GHz signal from base band I & Q signal.

Does this IC support up to 4.8 GHz signal generation?

LO Frequency range is given 300 MHz to 4.8 GHz. Does it means RF OUT(pin 18) shall be in that range?

In its data sheet i see in one of the typical application Ex, performance of TRF372017 in Table 29, RF OUT range mentioned is 300-4300 MHz!

TMS320F28377D: Uniflash421: Settings & Utilities: C28xx_CPU2: Calculate Checksum >>> Error

Hello,

My Uniflash 4.2.2 console output the following error message. Could you please advise?:

[ERROR] C28xx_CPU2: File Loader: Verification failed: Values at address 0x82B38@Program do not match Please verify target memory and memory map.


Test procedure:

- The source project was blinky_dc_cpu02 in C2000Ware_1_00_03_00.
- The source project was built by CCS740 in build configuration CPU2_FLASH.
- The output blinky_dc_cpu02.out was fed to Uniflash 4.2.2.

- Launch Uniflash 4.2.2.
- Program the blinky_dc_cpu02.out.
- Verify the CPU02 flash. >>> Error.


Findings
- The error points 0x82B38@Program. I attached its map file for reference.
- I also found that the Uniflash memory browser display the address 0x82B38@Program as all 0x0000. (Please be noted that my main point is the verify error.)
- The CPU02 finely blinked when the CPU01 was also porgrammed. Therefore the CPU02 program result should be okay. And the checksum was also okay. So the point would be just verification.

Linux/AM3358: nResetn is asserted low but not deasserting to high again

Part Number:AM3358

Tool/software: Linux

Hello 

I have designed a custom board of AM3358 based on the TI AM335x EVM. 

The board was booting fine and working fine till yesterday morning.Suddenly it stopped booting and even not responding with CCCCC in the uart . When checked properly its found that the nResetn ouput was asserted low and not becoming high at all.

The nResetn schematic was exactly maintained same as it was in the eval board. i.e. it is used as an output to reset to Ethernet section and connected to jtag .

The pin was pulled high with a pull up resistor.

What would be the problem and what could be the solution for this ?

Kindly reply at the earliest?

Regards

Mad_hu.
