Part Number:MSP430FR2522
Dear champion,
for these two structural methods, which is better from the perspective of stability? My customer wants to use self-capacitive mode.
1. PCB+2.4mm backlight + 1.5mm tempered glass
2. PCB with LED + spring + 1.5mm tempered glass (LED in the middle of the spring)

Hi there,
I am doing SI analysis of DDR3 Interface as a pri simulation, following the 5.13.8.2.1 DDR3 and DDR3L Routing Guidelines in the AM437x Data Sheet.
But I could not get a good SI result in the case of CK/ADDR_CNTL group signals based on "fly-by" topology recommended at the Guideline.
-> Please refer to the <A> of the figures in the attached file.
I tried the "balanced T" topology to these signals, and I got a good SI result on it.
->Please refer to the <B> of the figure in the attached file.
From these two results, I think I should adopt the "balanced T" topology to the groupe signals, not the "fly-by" topology.
Therefore, I would like to know the following conditions in this case.
1. maximum length of the CL/ADDR_CNTL signals
2. maximum skew between the CL/ADDR_CNTL signals
And if there is any concern of my decision, let me know.
Regards,
Shinji

Hi Ti Engnieers,
After build the target arago-core-tisdk-image the following 2 files about was generated:
deploy/sdk/arago-2017.05-armv7a-linux-gnueabi-tisdk.sh 533M
deploy/images/am57xx-evm/processor-sdk-linux-image-am57xx-evm.tar.xz 2.3G it seems similar with the contents after install ti-processor-sdk-linux-am57xx-evm-04.00.00.04-Linux-x86-Install.bin.
I know how to install the SDK bin file from your website -- ti-processor-sdk-linux-am57xx-evm-04.00.00.04-Linux-x86-Install.bin.
So the question is what's the usage the above 2 files?

Hi All
Happy New Year.
Now I am testing MSP430FR5994 launchpad now. I tested the ADC in chip only 8~9bit.I think this may be wrong.Could you give a MSP430FR5994 ADC in chip accuracy test report ？Thanks a lot.

I want to read a string via uart through serial monitor input. I am using TM4C1294 TIVA C Launchpad EVK. In my project, I used uart echo.c source file as reference. Please help.
Part Number:CSD25310Q2
Hi Sir,
Could you please recommend an alternative MOSFET for AP4453GYT-HF for Oring funtion (Vin is 5V)?
I couldn't find a similar spec MOSFET in our website so I'm not sure which should I choose for my customer.
Thank you very much.

Part Number:AMC1311
Hi expert,
I am trying to use AMC1311 to measure 48V battery voltage. In the datasheet, it recommend to use an amplifier to connect AMC1311 to single-ended input ADC. In my application, ADC is single ended, but i don’t want to use the amplifier before ADC due to limited PCB area. Thus, I am wondering if it is ok to connected VOUTP directly to ADC and use VOUTP-1.4V(common mode voltage) as the output result. If so, I want to know how to deal with VOUNT pin. Can I leave it float?
Though we can get rid of the amplifier in this way, it will introduce extra error due to the variation of common mode voltage. This makes it fail to meet 1% accuracy requirement. Thus, i am thinking of using to ADC to read VOUTP and VOUTN simultaneously and do the math in DSP. In this way, we can eliminate the error caused by common mode voltage, Please let me know your thought.
Regards,
Yangbo
Part Number:SN74AHC14
Hello,
My customer is considering this device but we need a little more information than is available in the datasheet. As the title suggests, we need to understand what the input range would need to be to switch the output on a rising edge input at Vcc = 3.3V over temperature.

I made a SD card with am57xx-evm-linux-05.02.00.10.img.zip, it can boot on IDK board(REV:1.0), can't boot on EVM board (REV:E2), console message as below:
Both boards have the EEPROM U56 on board, both left R328, R330, R329 DN, so the address should be same of 0x50.
Was the EVM REV:E2 did not flash Board ID in factory?
Please advise how to make the REV:E2 board work with Processor SDK 5.02.

Part Number:CC2652R
Tool/software: Code Composer Studio
I made a my own CC2652R Board with 2Mbit external flash (WinBond W25X20CL) and tried to limit OAD function using single image space of external flash. For this purpose, I change OAD_EFL_MAX_META from 4 to 1 and then try it, the OAD process always fail during OAD negotiation phase. Same issue occurs on both TI CC2652R1 launchpad(8Mbit flash) and my board(2Mbit flash), please help, thank you.
My code base is OAD+Multirole by referring to following link.

I have set UART boot mode in my board(BOOT pin as 111, GPIO4 is low ,GPIO7 is high for internal oscillator). Now i get Echo the character in Hyperterminal.
Next , i send a bootload .bin file as Txt in Hyperterminal (here, i am using hex55 tool to generate bootloader.bin file). next i send a application .bin file via Hyperterminal.Xmodem not respond occur.
Pls help me this UART boot programming method . my method is correct or not.?? Any other steps needed? please anybody give procedure for Programming method via UART boot ..
Thanks in advance.
Part Number:TMS320F2810
Hi,
I'm using Flash API Version 2.1 with the F2810.
I would like to modify the contents if the EEPROM during run time. When doing so 'Zero Bit Fail Error' is generated. I read that, to overwrite the contents, first the sectors should be erased.
Instead of erasing the whole sector, can I erase specific locations or a specific byte?
Part Number:CC3220SF-LAUNCHXL
Hello,
I am wondering if I could have some assistance with utilizing the external serial flash supplied with the CC3220SF-LAUNCHXL kit. I have been attempting to use the simplelink cc32xx sdk (version 2.30.00.05) in order to store data on the external storage, but have not had any success for now. I started trying to use the NVSRAM driver to simulate non-volatile storage, and was able to read and write from RAM, and this worked great! I then attempted to use the included NVSSPI25X driver by converting the NVSRAM code to comply to the SPI flash NVS implementation. However, the NVS function calls began to return unsuccessful status codes, and failed to write/read to/from the NVS chip. Using the NVSSPI25X driver, I am attempting to read/write raw data, which I assumed I would be able to do (I am not running an RTOS), but I read in some documentation that it is recommended to use a filesystem API to utilize the storage. Do you have any insight into how I can/should be using non-volatile storage on this launchpad? Are there any available examples I can look at that demo NVS? I can provide code samples if needed.
Thank you,
Marcus

Hello All,
I have created a following usecase to overlay some pattern on the display,
""""""""""""""""
NetworkRx (A15) -> Alg_Plugin (DSP1) -> Display_Video
OverlayLink (IPU1_0) -> Display_Grpx
""""""""""""""""
In the OverlayLink, I have ported C++ code for overlaying some data. To draw the overlay on display I am using Vision SDK function "Draw2D_drawPixel()". OverlayLink is similar to GrpxLink of Vision SDK.
So in my "OverlayLink_tsk.c" file, I have added "Task_sleep(10)" after calling "OverlayLink_drvProcessData()" in tskMain() function.
So my question here is, why do we need to add delay of 10ms. I tried to reduce the delay to 5ms and even tried to remove it, but my link OverlayLink doesn't overlay the data if I do so. Is 10ms delay a hardware requirement ?
I did the profiling of my OverlayLink and because of 10ms sleep for every iteration, it is taking a lot of execution time. Can anybody explain me why do we need this 10ms sleep time.
Thanks & Regards,
Abhay
