Hi,
In the MRR demo,two subframes are used,one subframe for the MRR context and the other for USRR context.If I just want to consider the long range condition, I only select the MRR subframe,whether it is feasible?
Thanks,
Rata
Part Number: TLV320AIC33
The TLV320AIC FAQ says:
The recommendation for unused inputs on TI's Audio ADCs and CODECs is to provide
an AC termination to GND through a ~0.47uF capacitor to prevent noise-pickup on
an un-terminated input. The analog inputs have a DC bias on them so they should
not be shorted directly to GND.
however the FAQ also says:
Whenever any of the analog input terminals are not used in an application, it is
recommended to short the unused input terminals together and connect them to ground
using a small capacitor (example 0.1μF).
Can this be clarified (one recommendation says 0.47uF per unused input, the other seems
to suggest 0.1uF per unused input pair)? Is it along the lines of:
When an input is being used single-ended, then the unused minus input should have
an AC termination to GND through a ~0.47uF capacitor to prevent noise-pickup.
When an input is not being used at all, then both the plus and minus input terminals
should be shorted together and be AC terminated to ground using a small capacitor
(example 0.1μF).

Part Number: DRV421
We are considering using the DRV421 in an inverter design operating between 200 kHz to 300 kHz. Is this a possible application for the part? Will it measure both positive and negative currents? Does any one have experience with a transformer design operating at this frequency? The current will have DC, high frequency, and 60 Hz.
Thanks for your comments.

Hi,
I am getting the below error at different moments of time after flashing and starting the application.
[ERROR2] - FATAL ERROR: Driver Abort detected.
Ping done. Success rate: 99%
Test failed: State = 5, Event = 17
Event handler failed..!!
How do I debug "Driver abort"?
Thanks.

Part Number: UC3845
Tool/software: WEBENCH® Design Tools
Hi;
I am working on Flyback offline SMPS using UC3845.
I have used TI WEB-BENCH online design tool, this tool automatic generated schematic as per my parameter requirement.
I confused when I saw TL-431 side, I failed to understand how TL-431 ref pin resistor value came?
Vo = 5V
As per TL-431 equation =
Vo = Vre (1 + (Rupper/Rlower) , TL-431 act as 10V Zener , but my output is 5V
How this tool calculated Rupper and Rlower resistor divider network ?
I have attached screen shot also, please check.
I have also uploaded pdf file of design tool.(Please visit the site to view this file)

Part Number: PAL16L8A-2M
Hi,
We want to replace our obsolete part PALC16L8-40DMB with your part PAL16L8A-2M. The main problem is that the lead size of your part is the way larger than our part lead and as we cannot make any changes to our boards holes so we will need to search for another part which has the same packaging as 20-Lead Ceramic Dual In-line with Window (JW) – 300 mil (CERDIP). I'd be grateful if you recommend us another part similar to
PAL16L8A-2M but with the above-mentioned packaging.
Thanks.
Part Number: CC3200
Hi Experts,
I'm using two sockets for receiving one is for MQTT listener and other is for Raw socket for receiving some data. I'm using FreeRTOS for that and both the listener are running concurrently but the problem is if Raw Socket is disabled then MQTT listener works fine but when the RAW socket is enabled MQTT listener either fails or gets blocked. How can I deal with that issue? How can I make both tasks to run parallely(i.e both listener are using sl_Recv)? Can both the tasks use sl_Recv and receive data simultaneously?

Part Number: WL1837MOD
Hi Experts,
I would like to make a loop back test for the evaluation of BT performance.
So I would like to have the documents which introduces test modes, etc, so that WL1837MOD could be connected to the BT tester.
Please let me know where I could find the related documents.
Also, If there is any GUI working on a PC, it would be very helpful.
Thank you for your kind help.
Best regards,
Hitoshi

Part Number: PROCESSOR-SDK-AM335X
Tool/software: Code Composer Studio
I followed the guide of TI to generate EtheCAT slave full project for am3359 step by step.But when I build the project on CCS ,there are some mistakes as below.I can not figure it out.Please to help me.Forgive me for my terrible Eglish and thanks.
Dear Sir,
We are making one product which will run on 4 series Pack of AA Batteries (1.5V x 4 = 6V).
These batteries are non-rechargeable.
Now we want to monitor the health of the batteries & end of life etc... etc...
Is there any IC for this application?
Low power ICs are recommended.

Hello!
I found many topics by the key word "cc1310 4 mbps" and now I want to try 1, 2, 4 mbps. I red that in the demo project rfPacketErrorRate there is smartrf_settings_predefined.c. But I can`t understand how do I have to change data rate and choose the modulation 4FSK or 8FSK when there are only CMD_RADIO_SETUP HSM and Overrides for CMD_RADIO_SETUP HSM settings. Can you send me an example file with smartrf_settings for HS mode and explain what parameters should I change to get different data rates? And how to generate smartrf settings in HS mode.
And another question. In the Long Range Mode what is relationship between symbol rate (20 kbps) and data rate (5kbps)? And what maximum data rate can be reached in the LR mode?

Part Number: TMDXIDDK379D
Hello,
First of all, thank you for providing this nice motor drive development platform.
For my PhD studies, I implemented the model predictive control of an IM on TMDXIDDK379D with small updates to the original code. It really shortened development time even though I had very limited programming experience.
To describe the fast and low-cost way of experimentation on model predictive control by using TMDXIDDK379D, we have recently published a paper in EPE2019 ECCE-Europe conference. Its title is "A Simplified Discrete-Time Implementation of FCS-MPC Applied to an IM Drive". You can download the paper from this link . (Inserting pdf in the desription box looked bad)
I am not quite sure whether this is the right platform for this post. I just wanted to share my experience for potential researchers of MPC because TMDXIDDK379D really helped me a lot as a tool.
Best Regards
