Getting Started with ATmega8 Microcontroller Programming using Arduino IDE. 

Since we will program an AVR microcontroller using Arduino, let's first understand what an AVR is. AVR is not an acronym for this microcontroller. It is a marketing term that stands for 'Advanced Virtual RISC'. The ATMEGA328P, ATMEGA88, and their equivalent microcontrollers use RISC (Reduced Instruction Set Computing) architecture, which works faster using fewer instructions.

Through this event, I presented all the easy and accurate processes of Arduino programming and simultaneously showed how to program ATMEGA8, ATMEGA48, ATMEGA88, ATMEGA168-20PU, and ATMEGA328P AVR microcontrollers. Learning to program so many models of AVR microcontrollers at once might be complicated, but no. The AVR microcontrollers mentioned have different capacities, but their circuits and wiring diagrams are the same, so let's get started.

To program an AVR Microcontroller using Arduino, you must first prepare the Arduino as an ISP programmer and upload the Arduino boot loader program to the ATmega8. The task is straightforward; follow the procedure given below to do so.

STEP-1

How to turn Arduino into an ISP programmer

First, connect your Arduino UNO or Nano to the computer using a USB cable. Then, launch the Arduino IDE Software  / Arduino program software.

1. Click on the File > Example > select Arduino ISP.
2. Click on the Tools > Board, then select your Arduino model from the board manager.
3. Click on Tools > Port, then select com port (Highlighted com port)
4. Click on Tools > Programmer > ISP > then select AVR ISP mkll.

Finally, upload the Skach by clicking the right arrow button below the menu bar. While uploading, the three indicator LEDs on the Arduino board will start blinking. After a few seconds, when one indicator lights up, and you will see the footer status bar indicating 'Done Uploading', you will know that the AVR ISP program has been successfully uploaded. Okay, now your Arduino is ready as an ISP programmer.

STEP-2

Content: OS-2S 94v-0 T-Con Board and V320BJ8-Q01 Innolux LCD TV Panel Repair Tutorial.

This edition includes OS-2S 94v-0 T-Con board test points voltages, CKV point-out review, and T-Con board repair guidelines. This board is installed in an InnoLux LCD TV panel, model number V320BJ8-Q01. The gate driver circuits of LCD panels of most models manufactured by InnoLux are COG or chip-on-glass technology, so in many cases, they are not repairable.

However, the OS-2S 94v-0 T-Con board is installed on V320BJ8-Q01 panels, combining gate COF and source COF in one film. The COF has two sets of CKV connections on the right and left side, so these panels are easily repairable and will last longer in most cases. That's why InnoLux should make LCD panels using OS-2S 94v-0 T-Con board technology to avoid our complaints.

Dear friends, In response to many of your requests on YouTube and Facebook, I have published the voltage details of all the OS-2S 94v-0 T-Con board test points in the images below. I have observed that many of you search on Google by typing "OS-2S-94v-0 Datasheet PDF." Although I have not published this here in PDF format, hopefully, you will find almost all the information you need for this T-Con board repair.
