Hi everyoneI need a library for ARM to implement DNP3 protocol. does anyone here know how should I do it? does send/receiving DNP3 packets make it possible?

The data sheet contains the following TestCircuit:I wanted to use it to check the switch in PSPICE. Unfortunately I don't get the same results as in the datasheet. If my assumption is correct: Could you give me a TestCircuit for a PSPICE circuit where I can check the data in the datasheet?

This is an EEPROM.​

Hi,I am using M34E04 I2C EEPROMread and write access works fine but I cannot enable write protection I have verified the WC pin is in the right state (logic 1) but I can still write to the device at this mode Any tip?RegardsAssaf

We are working on an IOT product for last 3 years. We were using other manufacturers EEPROM but then last year we switched to M24M02-A125, because of I2C interface and 4 million endurance cycle.But we are facing two problems with this EEPROM.1 - There is no option for entire chip erase.That's why i have to perform individual byte write, which takes too much time and is not good option for long run.2 - Page Write do not work on 3 out of 4 blocks of memory.In datasheet it is mentioned that this eeprom can be accessed by 4 different i2c address, which divides the memory in 4 block. For byte write, it is working fine, but for Page write, only 1st blocks works but that also skips the data at address with 0x01 0x00. (Lower Byte, Upper Byte).Why it is happening, there is no mention in the data sheet, what is the memory architecture inside this eeprom. How cells are arranged?Can you please more detailed documentation for this eeprom also is there any driver file available?Thanks alotWaiting fo

hi,here i am using the stvd studio .i want to change my workspace name .how can i change it.

I'm trying to get a datasheet of PSD813F2A-90J in the following site, but I couldn't find the correct datasheet there.https://www.worldwayelec.com/pro/stmicroelectronics/psd813f2a-90j/5183742https://www.worldwayelec.com/pro/stmicroelectronics/psd813f2a-90ji/5183743Hope you can help me as soon as possible.Thanks in advance.​​

Hello, Can you please suggest a drop-in replacement for the part: PSD4256G6V-10UI This seems to be a obsolete part.Thank you very much, Bijith

It is on a smart turbo trainer PCB and I need to replace it. any help would be much appreciated 🙏🏻EEG3 729Andras

Hello everyone, I really need help in using STM32Cube IDE and TrueAtollic Studio. I have searched up and down on YouTube, and I haven't found a single good video on how to use these IDE's. So I am using a STM32F030R8T6 and ST-Link V2 programmer-(https://www.amazon.in/ST-Link-V2-Automatic-Downloader-Programmer/dp/B00GD2S30S -this one) , there is a tutorial that uses this chip to learn ARM programming but uses CooCox IDE. I made my own PCB, it is not a dev board, just converts SMD to THT for breadboard use. If you know any good video/resource that explains how to use these IDE's clearly please let me know. I am just a hobbyist, doing this for a project, out of passion, I would love to start using this chip to make amazing things, please let me know. It would be amazing if you could help and support me. Thank you very much!

Hi,Ive been trying to use eDesignSuite to verify my design with L6983N50QTR. Please find my schematic attached. My specs are:ICL6983N50QTRTopologybuckInput7 - 33 VOutput 15 V (2 % ripple) - 1.9 A maxWhen I put the values that I am trying to use, I get the warning that the IL ripple is 30.27%, and bandwidth is 18.29kHz. In my schematic I adjusted the inductor to 10uH and added more output capacitors but how do I do it on eDesignSuite? I tried to change inductor value but it doesnt work. Could you please check this circuit and let me know if this is ok? Thanks

Hello, where could i find information about shelf life time for ESD protection HDMIULC6-4SC6Y with automotive grade?Thanks in advance for support!Best regards,

Hi,It's a problem is with device which is designed before 20years.Intro:·        The MSP430F4250 is connected with M24C64(EEPROM through I2C) used to log 2 Byte date for every 6 second. This was working with no problems for 15 years.·        Recently the M24C64 has made some Process technology change, they call it as CMOSF8H+(old processing technology was CMOSF8H). ·        So the old EEPROM was M24C64-(Batch_No)K which was working well and the new EEPROM M24C64-(Batch_No)T has been causing problem.Problem Definition:·        With new EEPROM when I read stored samples (Bytes), when it is less than 250 samples(500Bytes) I'm reading Garbage/Wrong Value for all the samples (Bytes).·        once the stored samples are greater than 250 samples(500Bytes) and when I read

Hi,i know the world has advanced, everything Now is Arduino this, Arduino that... BUT... i feel curious about old technology... to learn about old technology.for example the Fujitsu MBM2732A eprom, UV erasable. 25v programmable.Newer/later versions were 21v programmable.ST made a similar part M2732A found datasheets for both Fujitsu and ST...http://www.bitsavers.org/components/stMicroelectronics/_dataBooks/Memory_Products_Databook_Jun88.pdfhttp://noel.feld.cvut.cz/hw/st/4737.pdfhttp://search.datasheetcatalog.net/key/M2732ABut havent found the programming manual....or a good source to learn about EPROMS. reverse eng. or somethingthe same stuff old engineers used to learn.the forgoten art.https://archive.org/search.php?query=eprom= i need EPROM programers manual .pdf for Dummies. LOL Jajajajaja

Hi,Has anyone been able to interface the current sense functionality with a 3.3V ADC?

Hi,     Myself Thejas, on behalf of Aminod integrated technologies.Currently we are working on a Tracking System Project with the GPS Module(Teseo-Liv3F) ,from this module initially we are getting fine responses using the NMEA protocol(latitudue & longitude) . We have used the I2C communication to get the data from the module. Later we have changed to the Teseo-Liv3R module but we are getting only the gps header ( GPRMC, GPGGA, GPGLL) and all the latitude & longitude data are zeros. The same i2C communication is used for read purpose. We have used the same configuration and protocol that we had used to read the data from the Teseo-Liv3F module.  As per the datasheet, both ( Teseo-Liv3F & Teseo-Liv3R) has the same firmware configuration for reading dataplease do help in sorting out these issues ASAP.Please get us any sample code or configuration document to get the data from the  Teseo-Liv3R.&nbs

Hello, everyone. I try to use compact car ecu. It is based on ST10269 with dual CAN connection(drivers , power supply etc.) I need to make CAN filter from this device. Could you please show me some examples of routine code. For example (read CAN A - send CAN B; read CAN B - send CAN A)I allready install KEIL 5(4), but have not example for CAN routine. Somebody says that is Legasy MCU... Come on to STM32... But i try to give second life for thic MCU...|Please excuse me for my english.Regards.

I was looking to send instructions to X-NUCLEO using I2C , especifically the GetPos_I2C example but I dont know how set X-NUCLEO bord to recieve I2C instructions without the teseo-suite firmware. I was wondering if someone could help me with thatApplication note link -> https://www.stmicroelectronics.com.cn/resource/en/application_note/dm00528962-teseoliv3f--i2c-positioning-sensor--stmicroelectronics.pdf

I have 75s battery pack and i​ want to make short circuit protection circuit and load switch circuit. I facing some problem regarding finding MOSFET at at 288 volt and max 60 AMP continues current. Can any one suggest any MOSFET or digital switch which can handle that power.
