Slide 3:

System Requirements

To record this tutorial I am using:
  • Windows 8 operating system
  • USBasp programmer
Now, we’ll see how to install LDmicro.
OpenPLC website To download the installation files, open a web browser of your choice.

Make sure you have an active internet connection.

Go to the website https://openplc.fossee.in

Slide 4:

What is AVRDUDE?

What is AVRDUDE?

AVRDUDE stands for AVR Downloader Uploader.

It is a tool for downloading or uploading the on-chip memories of AVR microcontrollers.

Now we will see the installation of AVRDUDE.
Switch back to the browser.

Click ‘WinAVR’ Click on ‘WinAVR’ folder.

We can see a list of folders for different versions of AVRDUDE.

Click ‘20100110’ Click on the first folder available in the list, which indicates the latest version.

In my case, it is ‘20100110‘.

Click WinAVR-20100110-install.exe Then, click on WinAVR-20100110-install.exe.

This will download the executable file for AVRDUDE.

It will take some time to download the file.

Point .exe file In the Downloads folder, the downloaded .exe file is available
Right click on the .exe file.

Click on ‘Run as administrator’

Right click on it and select ‘Run as Administrator’.

Point the version number

Type ‘avrdude’ and press ENTER.

We can see the version of AVRDUDE installed on the machine.

Next, we will see about USBasp programmer.
Slide 5:

This is a picture of a USBasp programmer.

Slide 6:

Why USBasp drivers?

Why USBasp drivers?
  • A USBasp programmer is used to program the controller on OpenPLC Mainboard.
  • AVRDUDE will not recognize the USBasp, if drivers are not installed.
Now, we’ll see how to install the USBasp driver.
Switch back to the browser.
I’m using Windows 8 OS to do the installation.

The procedure is the same for Windows 10 also.

First, we need to download the installation files.
Click ‘USBasp drivers’ link

Text box: These installation files are for both Windows 8 and Windows 10

In the Windows row, click on ‘USBasp drivers’ link to download them.
Point the .zip file In the Downloads folder, we can see a .zip file of USBasp drivers.
Right click >> Click ‘Extract All’ Right click on it and select ‘Extract All’.
Click ‘Extract’ Browse to the location where you want to extract and click ‘Extract’.

I’ll extract to the Downloads folder.

Connect the USBasp programmer to one of the USB ports of your PC.
Open Windows search Now, open Windows search.
Type ‘Device Manager’


Search for ‘Device Manager’.

In Windows 8, we can find ‘Device Manager’ under Settings

Click on Device Manager.

Click ‘Other Devices’

Point ‘USBasp’

Click on ‘Other devices’.

We can see ‘USBasp’.

Point yellow sign The yellow sign near USBasp indicates that it’s not connected.
Right click on ‘USBasp’ >> Click ‘Update Driver Software’ Right click on it and select ‘Update Driver Software’.
A window will pop up with ‘How do you want to search for driver software?’.
Click ‘Browse my computer for driver software’ Click ‘Browse my computer for driver software’.
Browse to the location

Click ‘Install’

Browse to the location where you have extracted the ‘USBasp drivers’ folder.

I’ll change to Downloads.

Click on Next button.

Point the message But, we can see a message as:

Windows encountered a problem installing the driver software for your device’.

This is because there is a driver restriction for non-digitally signed drivers.

Only digitally signed drivers are allowed in Windows 8 and Windows 10

Therefore we have to disable the signature checking.

Press SHIFT and Restart To do that, hold the Shift key and restart the computer.

The computer will restart with some clicking options on the screen.

Click ‘troubleshoot’ Click on ‘Troubleshoot’ option.
Click ‘Advanced Options’

Click ‘Startup Settings’

Then click on ‘Advanced Options’.

Click on ‘Startup Settings’.

On Windows 10, it might be on a second page, after "Show more settings".

Highlight the options A new window opens with the message:

after restart you will be able to change some windows options’.

Click ‘Restart’ Now simply click on the Restart button.

When the computer reboots it will show some options on the screen.

Press 7 Press 7 in the keyboard to select option 7, i.e. ‘Disable driver signature enforcement’.
After that, the computer will start Windows normally but now with disabled driver signature detection.
Now again go to the ‘Device manager’ and try installing the driver as before.
We’ll get a warning that says ‘Windows can’t verify the publisher of this driver software’.
Click ‘Install this driver software anyway’ Ignore it, and click on ‘Install this driver software anyway’.
We can see a message ‘Windows has successfully updated your driver software’.

Click on the Close button.

Point ‘USBasp’ in ‘Other devices’ Now we can observe that the yellow sign at USBasp is not there.

Thus, USBasp drivers are successfully installed and working.

This brings us to the end of this tutorial.
