TPS65218D0: VnPUC at Battery-Backup Supply Power-Path

$

Part Number:TPS65218D0

Hi Team,

What is "VnPUC=2.3V" at 5.3.1.12 Battery-Backup Supply Power-Path on page 36 of TPS65218D0 datasheet?

From the TPS65218D0 datasheet, "VnPUC=2.3V" was added at 5.3.1.12 Battery-Backup Supply Power-Path. TPS65218B1 datasheet did not have that.
TPS65218xx Silicon Revision History sheet does not included the "VnPUC=2.3V".
What is "VnPUC=2.3V"? And why was "VnPUC=2.3V" added?
Thank you.

Best Regards,

Koshi Ninomiya

Part Number:TDA3XEVM

Hi,

If the FFT Control Parameter is set to do both Horizontal and Vertical, how do I gain access to the 1FFT output buffer? I looked at the radarFft2.c code and saw intermediateBuf. Is this the 1FFT output buffer? I would like to get a hold of the 1FFT buffer and perform a power level check on the data on a per frame basis.

Thanks,

Part Number:AM5746

Tool/software: TI-RTOS

Hi.

My customer were reading AM574x TRM and they had the following question.

It is written as follows in Table 2-3. L4_CFG Memory Map (OCP2SCP1)
0x4A09_4000-0x4A08_43FF 1 KiB Reserved
0x4A09_4400-0x4A08_47FF 1 KiB Reserved

It is also written as follows in Table 26-63. PCIe PHY Subsystem Instance Summary
PCIe1_PHY_RX 0x4A09 4000 1KiB
PCIe1_PHY_TX 0x4A09 4400 1KiB

Is 0x4A09_4000~0x4A08_43FF reserved?

CCS/MSP430FG439: Data process/conversion of MSP430FG439

Part Number:MSP430FG439

Tool/software: Code Composer Studio

Hi,

I am now working with MSP430FG439 by the pulse oximeter made by myself. The pulse signal I obtained through Labview_GUI(slaa458) is pretty good. In order to further analysis the data, I tried to use IAR MSP430 to collect the data. However, the data I got from IAR is weird (The data seems like the raw data that requires to process). When I simply plotted the data from IAR would present the noise all the time. Any idea how can I process the raw data from IAR? Or is there any other way I can obtain the processed the data from the microcontroller as the data from Labview_GUI?

Any method is okay for me, as long as I can get the data like the one in Labview_Gui,  

I am totally new to this area. I really appreciate any help!

CC1350: Searching for a simple subG interface to a particle.io electron (or similar)

$
0
0

Part Number:CC1350

I am searching for a straightforward way of establishing a subG wireless interface with Particle.io Electrons. I use Electrons (and Photons) to communicate physical security and equipment status information. I monitor boring, but important stuff like backup generators, sump pumps, sewage ejector tanks, access gates, etc. Right now, Particle.io has no off-the-shelf subG interface to their hardware, which has mostly worked well for me on the WAN side. I have Particle's Argon and Xenon mesh devices, but these require a 5V power source.

I have two CC1350 Launchpads communicating using the out-of-the-box concentrator/node example, but I haven't done much beyond that. (I do have a box full of other launchpads and SensorTags from other projects and classes.) I am well aware of terrific benefits of subG communication since I use 315, 433, and 915 in my lighting control (Lutron) and alarm (DSC) installations.

I'd love to find a TI subG transceiver that connects to an Electron/Fona/whatever and is able to receive simple data from a variety of sensors built with matching TI wireless -- not unlike the Launchpad pair I have right now. I don't have the chops (or interest) to write a library and am hoping one exists. I've tried to figure this out on a variety of forums, but the discussion is either way out of my league or it's some esoteric discussion of the merits Zigbee/6LoWPAN/ZWave/Thread/Lora/Sigfox/Cat-M1... I've looked at every reference to "texas instruments" and "ti" on the particle.io forum, but couldn't find anything useful.  I've looked at all sorts of hubs, but none are open enough for my purposes and most use wifi.

I need a solution that gets me completely off my clients' wifi networks. The Electron does this well, but it's $3/month/Electron, which is fine for small installations, but doesn't scale well. I've used Adafruit's Fona with similar success.  My data needs are so trivial that I never hit the data cap.

It seems like TI is killing it in battery-powered, subG solutions and that something simple should be within my reach.  Right now I don't care much about encryption/mesh/BLE/etc. For v1.0 I am just looking for the simplest solution that is portable enough to add those features later.  

The solution can be ugly right now as my clients never see these devices or the MQTT interface. Full disclosure: I've had devices in the field for years that are basically bread-boarded science projects hidden in Hammond boxes, but they work well.  I've been reluctant to develop any permanent product-like solutions since I know my architecture is immature. Regardless of how the WAN side sorts itself out, I am confident that battery-powered subG is the right way to go locally.

Can anyone point me in the right direction?  Sorry for the open-ended inquiry.  Green-field right now.  I know I can expand my business if I can figure this out.

Thanks.

Part Number:BQ40Z80

I have a new BQ40Z80 device that I am programming today.  The FUSE bit is permanently high, even though I have no permanent faults and no safety alarms.

I have tried resetting, clearing permanent faults, power cycling, shutdown, toggling FETs, toggling FET_EN and GAUGE_EN, resetting lifetime data, and everything else I could think of.  I'm not sure what else to try besides replacing the chip or erasing it and reprogramming it.

Here is a shot of my status registers.

Here's a shot of my main settings:

Thank you for your prompt assistance.

Resistance Rs Causing failure to start

$

0

Evaluation board:  drv8301-hc-evm revd

Lab 10a Overmodulation

1. Because our products require normal output torque in the environment of 0-50 C. In the environment of 50 C, Rs is required to take a larger value to make the motor output torque, but at this time in the environment of 0 C, the motor will start over-current problem, how to solve it?

2. Because our products require normal output torque in the environment of 0-50 C. In the environment of 0 C, Rs is required to take a smaller value to make the motor output torque. At this time, the motor can also start normally, but at this time in the environment of 50 C, the motor has no output torque. How to solve this problem?

3. Because our products require normal output torque in the environment of 0-50 C, is there any scheme that can be compatible with both high and low temperature environments? Resistance Rs on-line identification value is not accurate and can not meet the high and low temperature performance. Is there any other suitable scheme?

UCD9248: How to turn on UCD9248's PWM on powering up?

Part Number:UCD9248

I get a firmware formatted as a hex file. I import this file with checksum writting check box on. I can monitor the output power of the power stage using Fusion digital power designer, but I have to click turn on button. When I do connect the USB adaptor and the Fusion software, the output power is not automatically turnned on. What is the reason? Is it because the reset pin of UCD9248 is pulled high to 3.3V power without a capacitor to ground? I think this is not the reason because UCD9248 has internal power on reset function according to datasheet.

Thank you.

Compiler/MSP430FR6972: The question of MSP430FR6972's WDT Reset

Part Number:MSP430FR6972

Tool/software: TI C/C++ Compiler

Hello,Masters

         I have a problem which the cpu  is always  reset .  First the program is running normally and the WDT is opreation.  After some hours  or some days , the CPU starts to reset again and again. It couldn't be normal any more . Unless  the programs run the codes as flowing , the cpu will be normal again .                                                                   

                                                                     PMMCTL0_H = PMMPW_H;
                                                                     PMMCTL0_L |= PMMSWPOR;
                                                                     PMMCTL0_H = 0;

So, I  think that WDT REST couldn't clear the RAM,  PMMSWPOR could clear the RAM, is right?  If  It is right,  I think that  some wrongs make the datas in the RAM  Incorect .

     What do you think about the phenomenon ?

                                                                                                                                                  Best Wishes

UCC28070: ucc28070 : relate to calculation Icout _hf

Part Number:UCC28070

Hello

I am working on 1kw PFC using ucc28070.

Firstly I try to calculate some parameter using UCC28070 Design tool.

But I can't find any formula due to locking in excel sheet.

So I refered to UCC28070 300-W Interleaved PFC Pre-Regulator DesignReview. I can matched between  design tool and I calculated.

I discovered some difference value in design tool relate to Icout_hf

This formula is correct?.. Could you plz check. 6pi  is different compare to bellow formula. (https://e2e.ti.com/blogs_/b/powerhouse/archive/2016/06/14/predicting-output-capacitor-ripple-in-a-ccm-boost-pfc-circuit) Bellow formula is not 6pi but 3pi.  When I use 3pi I can get similar result compare to design tool. 

So I think  3pi is correct value instead of 6pi.  Could plz check which formula correct is. 

thank you

Part Number:LP5569

Dear expert,

My customer are designed their system with LP5569. and have some question need your double confirm.

They would like to control LP5569 via I2C without SRAM, may we learn form you which registers I need to set up?

Thanks!
