SinaProg Program Download Guide will help you learn how to download hex file into all AVR microcontrollers. Connect the AVR USB Programmer to the PC to Laptop directly or with the help of USB AM-FM Cable provided with the AVR USB Programmer package. Then, Connect the AVR Trainer Board-100 or any other microcontroller board that you have, with the AVR USB Programmer through the 10 to 10 FRC Female connector provided with the AVR USB Programmer package.

Then, Open the SinaProg Software by Double Clicking the SinaProg icon. The SinaProg looks as below picture.

Click the “Folder” icon in the Hex file section and browse for the Hex file of the project, which you want to download to the microcontroller and Select the HEX file. Example – Led_Blinking.hex.

Then, Select the microcontroller to which you want to download the code/program from the drop- down list in Device section. Example – ATmega16 or else, if the microcontroller is connected to the AVR USB Programmer then, Click the “Search” button in the Device section. This will read the signature byte of the microcontroller and according to the signature value, it will automatically select the microcontroller for the Device section.

Then, Select “USBasp” in Programmer and “USB” in Port from their respective drop-down list in the Programmer section. The first one selects the Programmer type which we are using and the second one selects the Port that is used by the programmer. The below picture shows the SinaProg window after all the above settings:

Click the “Program” button in the Flash section to start the download of code/program (Hex file of project) to the Flash memory of the microcontroller. The below picture shows the status of code/program download in Status section.

SinaProg-Program-Download-Guide-3-ABLab Solutions

If the code/program download succeeds, then “Programming Flash…OK” is displayed in the Status section band if the download fails, then “Programming failed” is displayed in the Status section.The below picture shows the Status section when download succeeds and fails.

SinaProg-Program-Download-Guide-4-ABLab Solutions SinaProg-Program-Download-Guide-5-ABLab Solutions
Download succeeded. Download failed.

If the AVR USB programmer is not connected or if the PC/Laptop can not detect the AVR USB Programmer and code/program download is tried, then “Can’t find programmer” is displayed in the Status section. The below picture shows the Status section for the above condition.

SinaProg-Program-Download-Guide-6-ABLab Solutions

To know the detail result of the last code/program download, Click the “Arrow (>)” button in the Status section. This will open another window which will display the last download results in detail. The below picture shows the SinaProg window with the arrow (>) button clicked.

SinaProg-Program-Download-Guide-7-ABLab Solutions

Now, you have successfully downloaded the code/program that you have written (Led_Blinking) and its time to test the code/program of Led_Blinking in the hardware. Do the required connection in the hardware according to the code and see the output.

Installing OpenCV in Raspberry Pi

1) First, be sure that the Raspberry Pi is connected to internet.
2) Update the system by typing the “sudo apt-get update” in the terminal windowRaspbian update

3) After that upgrade it by typing “sudo apt-get upgrade”. It will take nearly half an hour to some couple of hours depending upon speed of the internet.

Raspbian upgrade

.4) Install the OpenCV by typing “sudo apt-get install libopencv-dev python-opencv”. And this also takes nearly half an hour. ( depending on your internet speed :))Install open cv

Note: Raspberry Pi and internet connection should not off until the completion of the whole installation process.
