I urgently need an 3,3V Com port to update firmware in an another MCU from an another manufacturer.

If possible I would like to use  the ATmega328PB Xplained mini board (because I have it :)

Is there any possibility to find, download and install a Windows 7 Ultimate (or WXP, W81 or W10) simple and small USB driver for it ?

I was trying to install all versions of Atmel Studio 7.2 - but I always got the message: "The specified program reqiures a newer version of Windows"

The version 6.2sp2.1563 started to install, but nees too many disk space on C: and also started to install some Microsoft stuff which warned me that I should prepare to enter some large licence number - so aborted the installation.

I do not need a large development environment, what I need now is only this 3,3V RS232 COMx port ...

Is there a way how to acomplish this simple problem without wasted GBs of RAM and hours of time ?

Thanks ZM

Not entirely clear what you are asking for. Are you just looking for a low file count to ISP program the 328PB. If so I would have thought a $2 USBasp and the 3 files (is it?) that are needed to run avrdude.exe would be enough. But that only buys you the ability to program HEX files into the 328PB. If you want to develop code for it as a minimum you need an assembler but more likely you need a C compiler. Perhaps you could simply get: 

 

https://www.microchip.com/mplab/...

 

That would deliver just a C/(C++) compiler for AVR with the rest of AS7s IDE "baggage". Of course you still need an editor but it's quite possible to use just something like Notepad++ as you "C editor" for AVR then invoke the build tools at the command line. Then again you might want to add GNU make to that or perhaps just a .BAT/.CMD that invokes the compiler/linker/objcopy is enough?

 

I think you need to be more specific about what you want to achieve.

 

The thing is that while you can "cut down to bare essentials" the chances are that any such solution is more work to learn and use than fully integrated solutions like AS7 which includes and does pretty much everything you need in the simplest possible way.

 

(actually I say "AS7" but there are, of course, alternatives like Imagecraft and Codevision etc - again the chances are the more you pay the easier things get - in part because, when things don't go to plan there's someone on the end of a telephone line who will be able to help!)

You might not need to do anything with the  AVR!...keep it in reset (or pull the resistors) & just tap into the serial connection.

 

the 328PB board has a usb to 3.3V converter

The mEDBG (ATmega32U4) USART is used for communication with the CDC COM port. The USART

TX/RX signals are available on the J104 header and are also connected to the ATmega328PB via 0Ω

resistors enabling easy disconnect from the ATmega328PB, if needed.

 

http://ww1.microchip.com/downloads/en/devicedoc/50002660a.pdf

 

Info: The virtual COM port in the mEDBG requires the terminal software to set the data

terminal ready (DTR) signal to enable the UART pins connected to the ATmega328PB. If the

DTR signal is not enabled the UART pins on the mEDBG are kept in high-z (tri-state) rendering

the COM port unusable. The DTR signal is automatically set by some terminal software, but it

may have to be manually enabled in your terminal.

Yes. exactly :) I can buy it even far cheaper at aliexpress.com ;) But I have to wait for about 35 days :(

1) I needed to update some firmware of an another MCU (not atmel)

2) in another words I needed an RS232 interface (let say "COM") with a 3.3V amplitude

3) unfortunately the RS232 interface was originally coupled with the V24 (+/-12V) range, later with the "IBM range" +12/-5 and finally - simply with the TTL universe >2,4V, <0,8V   

4) based on some earlier unfortunate events I found in my drawer an "Atmel Xplained Mini" board with an simple 8 bit MCU, USB interface and a lot of ununderstandable pins - but two of them have the sought  labels TX and RX !

5) based on this, I wrongfully expected  that all I need is to download fom somewhere some .com, .exe .msi or .dll file ("the driver") and install it. Because it should be only a simple RS232 interface I expected, the file shold be not larger than - let say ~1kB.

6) insted of this I only found - after hours of browsing - a big lot of terrible, horrible, gruelsome and frightful stories about the installation of Atmel Studios 4 - 5 - 6 - and 7

7) by the way I solved my problem in the meantime with an ST Nucleo  board STM32F103 - wich is 32bit and is running without any problem also with an ancient Windows XP :)
8) to be honest the hidden reason of my primitive posting have been two far more important socio-econmical questions A) has Microchip really destroyed Atmel ? B) is the Trump's America really going down ?

9) many thanks for your participation, have a nice day and take from time to time also some look out of the window - an  Megaphragma mymaripenne wasp brain has only 4600 active switches ("neurons") - which corresponds rougly an Intel 4004 4bit MCU  - and with this small number of active parts can make image recogniton (the wasp has eys !), can fly and make complicated maneuvres, can attack prey, can defend and can even reproduce itself ...

So please do not tell me that for every shit is ultimatetely necessary a C++ compiler and a desktop with at least 16 GB RAM (the human DNA needs for its storage only a 4GB flash drive :)

All :) Installed: XP, 7, 8.1 and 10.

 

Because of other reasons I wanted to use XP or 7.

 

(I plan to delete the 8.1 because of compatibility problems

and 10 because I am old enough and I am not looking for

a Big Brother - on the other side I like W10 more then

W8, W7 and WXP - the only Windows I really loved was

W2K. I started With Windows 2  and MS DOS 3.1 - and still

ave the red CDs with alfa version of Windows NT ;)

Bingo !!!

You solved it !

I already desolderd the 0 Ohm "resistors" R107 and R108 (below the XC100 16MHz crystal/resonator) ...

The only little-little-little thing - I am missing - is the Windows 1/2/3/3.1/3.11/95/98/ME/NT/2K/XP/Vista/7/8/8.1/10 USB-to-COMx driver :(((

 

PS sorry - joke - I assume my HW would not more accept Windows 1/2/3/3.1/3.11/95/98/ME/NT :(

 

Have a nice weekend  and thanks for the response - I know I am demanding an unobtanium - because why to use 1kB if 1TB is nowadays so cheap :)

If you connect the board into the PC, windows should go off & find the USB virtual comm driver for you automatically.  If that fails, certainly, Microchip/Atmel would have it, in a box on the third shelf, in room 407, of building 12.

Strange but during the past century Windows never found the necessary driver :(

I would really like to know what for is this function there ?

Unfortunately I only found a roll of toilet paper in the box on the third shelf.

Because room 407 of building 12 is WC ...

Anyway thanks for the hints ;)
