Is there any support for UNO R3?

I moved your topic to an appropriate forum category @toxic_lens.

In the future, please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.

This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Hi @toxic_lens. Please try this experiment and then report back with the results:

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

  1. Connect the Arduino board to your computer with a USB cable.
  2. Press and release the button on the Arduino board that is marked "RESET".

Now please reply here on the forum thread with the answer to the following question:

  • Did you see the "L" LED blink multiple times quickly immediately after you released the "RESET" button?

Thanks for following the forum guidelines in posting your code. Did you select the UNO in the tools menu?

5

yes, he did
uno

6

Yes it does. But the "L" LED is always blinking.

7

OK, no problem. This is my 1st post here. I'll be more careful from now on. thanks.

Let me correct that. The "L" light did not blink quickly multiple times. It just started a slow blink - about on/off every second.

9

You installed the Blink.ino sketch.

10

@xfpd I guess Blink is there from factory

11

This means the Arduino board is not getting the response it is expecting.
Go to the menu Tools -> Port and select the port you see for your Arduino.
If in doubt look at the ports available with your Arduino unplugged. Then plug it in and look again. The new one on the list will be the one you need to select.

Hi, @toxic_lens
Have you selected the correct port?

The UNO is port 7 on my IDE.
It will be different in yours.

Have you been able to upload from that IDE before, or is it the first time?

Tom.. :grinning: :+1: :coffee: :australia:

COM3 is the only port available that I can see. When I select Board Info from the IDE, it says "Unknown board". This is an OSEPP Uno R3 Plus board. It used to work but the last time I tried was almost 10 years ago. I'm just getting back into it now. I'm thinking that there's a problem between this board and Windows 10. Does that make sense? I'm thinking of just buying a genuine Arduino Uno R4. Good idea?

14

I think it's there from the factory.

15

Yes, blink.ino is factory-installed.

Yes it does. It is likely that with all the updates it has received since it was released in July 29, 2015 that something has been lost.

Never come across this clone before. I assume you have read the web page
https://osepp.com/electronic-modules/microcontroller-boards/105-osepp-uno-r3-plus
Where it says:-

• the UNO R3 is legacy hardware. Production for the UN R3 has ceased as of June 2016. This page serves as reference material.

Curiously about a year after Windows 10 was released. When I tried to download the schematic my web browser (Firefox) blocked the request on security matters. It is not very often that this happens, so I was unable to see what sort of USB to serial chip it uses. It could be that it is not one of the standard ones and could even be a CH340 chip, that you would need a driver in your PC in order to use.

The schematic for the OSEPP Uno R3 Plus board shows that it has a FTDI FT232RL chip as the usb/serial converter. That's a different chip than the official Arduino Uno R3, and it's one with a somewhat storied history. At one point, MANY of the Arduino-compatible board using this chip were apparently using "counterfeit" chips (it's not clear where the counterfeits entered the supply chain; ie whether the board level vendors intentionally bought cheap chips from questionable places, or whether they thought they were getting real chips.) They mostly worked fine until FTDI modified their windows driver specifically detect the counterfeits and "brick" them. This was met with a lot of negative feedback, and FTDI relented, only to later modify their driver to simply not work with the counterfeits. This was still unpopular, and was one of the thing that has led to less use of FTDI chips.

I don't know the current state of all of this.
You can try installing the latest driver from FTDI and see if that changes anything (at some point Windows started include a driver for these automatically, but I don't know if it's the same one.)

PS: I do NOT recommend an Uno R4. It has very poor compatibility with the Previous Uno variations, since it uses an entirely new CPU chip.

Check also the USB cable. Some are intended only for charging and don't have the data wires which are necessary here.
