Hi everyone;

I would like to make a remote control. I found this exemple of IC controller AD009-08L as shown in the picture. But I'm searching during days and days but still didn't find a solution how to program this IC.
Can anyone help me how to program this IC ? What is the programmator used (Hardware) ? What is the user interface ? ... ?

If you know other remote control ICs and you know how to program them that's welcome also .

 

I have never seen this part. What does it do? I see it "decodes" a keyboard. Why do you think it is programable?

 

It is possible that those chips are not re-programmable. What is your goal? Are you trying to repurpose a remote control for something else? If you just want to know how the code works, there are surely multiple remote control projects for Arduino out there, including code to learn signals from existing remotes and replay them. There is also code for grid type button arrays. I would bet $1 there are similar projects for Pic, Arm and many other platforms as well, probably in multiple languages including assembler.

It is an encoder IC. It is for managing the key press of the pushbuttons in the remote. I mean each button has its own signal / code to be sent later with IR LED.
Yes it is programmable: look a at the datasheet of AD009-41 in this link below:

I guess it is not re-programmable but it is an OTP (One Time Programmable), so at least it is programmable once .
Not I'm not intending to read remote control codes. As you said there many projects with Arduino to read remote control codes. I'm actually looking for to program an empty IC and make the remote adapted with the TV.
So my imagination is as follow: Read the codes and then program the IC with the suitable codes and right pins configuration, ...
That's it

Yes I'm aware of this. And I'm capable of having a new empty one.
Is there an idea how to program ?
Any other similar device is welcome if you know the way of programming

 

Hi B,
This is the best link I have found.

"Editable remote" Use a reprogrammable MCU, such as Arduino, Atmega, PIC and many others.

 

The chip is actually an MCU, you would need to have a program just like a PIC or AVR MCU. You’d be better off using one of those that have robust development tools available for free.

Edit: You would need to add a MOSFET to drive the LED.

Hi! Programmable yes.... But reprogrammable... Probably not..

I have looking for make the same project. Nothing found yet. If I found something I will let you know
