Part Number:THVD1450
Hi,
I am using THVD1450 in half duplex mode.
In case of both RE and DE are enabled (But there is no communication going on) and if l B channel is grounded (PCB common ground) and there is no signal on A.
What could be the possibility. Is there any chance of damage to IC. Amy violation of maximum operating condition. or something else.
Thanks
Part Number:LM25005
Hi,
I want to use the LM25005 as a negative Boost converter, Uin = 12V, Uout = -15V, I = 0.5A.
I attached the design pdf in this post.
My question is now, how can I manage to feed my enable signal and sync signal (both referred to Input ground) to the circuit?. In the design the AGND pin and also the RT pin are referred to -15V in my case (see circuit on fist page). But my signals are referred to input GND and not to -15V.
Could you please provide my more information about this toptic? (Please visit the site to view this file)
Part Number:AWR1642BOOST
Hi team,
We develop SRR application with SDK 2.0 for several months.
And we move SRR application from SDK 2.0 to SDK 3.0.
There are many build errors.
Is SDK 3.0 support SRR application or mmw demo application?
Thanks
Part Number:UCD90120A
i'm trying to configure(its inside xilinx ac701 rev 2) my device with the "firmware & configuration download tool" but I get the following error:
"11:17:14.522 could not read DEVICE_ID from address 101: NACK; it is impossible to download a project file to a device if it's DEVICE_ID can not be read; this indicates a serious communication or firmware error that must be resolved".
I scanning for the device with the " UCD9XXX Device GUI" I pressed the "scan device in ROM mode" but all I got is "11:10:59.703 Found ROM v2 IC v2 - UCD30xx".
when I tried scan with the "DEVICE ID" button I get "11:12:41.998 No devices found"
the ac701card i'm working with is used but supposed to work.
thank in advance,
yuval.
Part Number:DS250DF210
Hello E2E,
Q1;
I chose TPS62825 for 2.5V output power supply DC/DC.
Is this DC/DC suitable for DS250DF210?
Q2;
Is a filter necessary for the 2.5V power supply? Is it L-C filter?
If necessary, please let me know how to design for filter.
Kind regards,
ACGUY
Part Number:CDCE913
Dear Sir,
My customer is interesting in using CDCE913 for reference clock generator.
I could not find simulator nor a phase noise performance data/graph in the datasheet.
Do you have a sample measurement plot or data or simulation to be shared?
CECE913 gets 10MHz input and 140MHz output which will source to LMX2594. Within 100KHz offset phase noise is very critical.
Best regards,
Masa
Part Number:DS90CR218A
Please let me know about calculation for tolerate maximum clock frequency.
Before using DS90CR216A on 36MHz clock.
But latest model is changed 36MHz to 45MHz, DS90CR216A occurring bit error on deserialization.
I want to decide that change DS90CR216A to DS90CR218A became no bit error and the other risks by calculation.
Best regards,
Satoshi
Part Number:TMS320F28379D
Tool/software: Code Composer Studio
Hello,
I'm working for an engineering school in switzerland and for a project i have to make the communication between different system by using CAN BUS protocol and with an F28379D. By now i try to understand how the CAN communication work and i'm not very well train to code with MSP so i want to ask you if you have a code to learn how to test the CAN communication on a docking station using a F2837x controlCARD
many thanks
Part Number:CC1312R
Hi,
My customer is using CC1312 with Contiki-NG.
According to their investigation, the packet size is fixed as 127Bytes including header, etc.
This is probably due to the frame structure is based on IEEE802.15.4.
Is it possible to increase the maximum packet size? If yes, how?
Thanks and regards,
KoT

My board is AM572x Industrial EVM REV 1.3B
SDK Version:ti-processor-sdk-linux-am57xx-evm-05.00.00.15-Linux-x86-Install
I downloaded the adb and fastboot tools on the windows host, then run cmd to open the command line window. After my board enters uboot, I run fastboot 1, then I run fastboot devices on the windows:
This device has been detected from above.
But when I run fastboot flash bootloader u-boot.bin,it was failed:
What should I do if I want to transfer image files of uboot, kernel, etc?
Part Number:CC2538
Dear all
I had use SmartRF Flash Programmer 2 + xds110. but there are some questions about it.
1. After burning the program, the debugger connected to CC2538, CC2538 is powered off, then powered on, the program can be run normally, but if the debugger is not connected to CC2538, the program can be not run normally .Why?
2. If I want to the program run normally, what can I do ? Is there some I/Os must be set high or low before power on ? or is there any configuration problem with the compiled project ?
Part Number:TPS65910
Hi
We will connect BOOT1 and PWRHOLD to VRTC.
(Due to no RTC feature requirment and EEPROM boot)
Is it needed pull up resistor?
Or could it be possible to connect directly?
BestRegards
Part Number:TM4C123GH6PM
Tool/software: Code Composer Studio
Hello,
I am writing a ros_embedded program using github.com/.../rosserial_tivac
I need to measure time, in order to make a loop execute a routine each 100ms.
Usually this is done with something like:
while(1) {
current_time = micros();
if(current_time - last_time >= 100000) {
// execute routine
}
}
In tiva-c there is the SysCtlClockGet() - which returns 80000000 - when the TM4C123 is running at 80Mhz.
Is there any way we can get the sysclock ticks? Basically, I would like to do a blink without delay in the TM4C.
Are there anyways to accomplish this other than the use of measuring the time / clock timers? (maybe the systick interrupt)
Either way, how do I measure time in the TM4C? Sometimes I just need to temporarily measure how long a routine takes for debugging purposes.
Best regards,
Can
Part Number:LM8335
Hi all,
as far as I know, the MSP430F5510 on the LM8335EVM implements a USB to MIPI RFFE interface. I'm highly interested in the MSP430's firmware and would highly appreciated if it could be provided.
Many thanks in advance,
Mathis Schmieder
Part Number:TIDA-00274
Hi,
For my project I am planning to control my BLDC motors sensorless. The InstaSPIN technology seems interesting for back-emf sensing, however it is a bit confusing in the TIDA-00274 module.
The list of features states that the MSP430G2553 MCU provides the InstaSPIN technology, however this is not listed in the module's datasheet. In the MSP430G2553 MCU datasheet, InstaSPIN is also not mentioned.
Does the TIDA-00274 module provide InstaSPIN, or specific, does the MSP430G2553 MCU provide InstaSPIN? Or are, for instance, TMS320F280xxx controllers needed?
Thanks,
Jasper
Part Number:DP83867IR
Hi,
For one of our project, we required 10/100/1000 Mbps and PTP for time synchronization with central time server.
Planning to use DP83867IR PHY but as per my understanding datasheet says it supports IEEE1588 SOF and time syncronization algorithm need to be custom develop.
Kindly please share me the implementation of time syncronization algorithm, IEEE1588 interface and if any reference design available.
Thanks & Regards,
Vijay Varma
