infrared receiver (by Magno Medeiros (Brasil))
Hello everybody,
someone could help me with a diagram of a transmitter and an infrared receiver (remote) so I can program in ladder. I appreciate any help

Hello Magno
Try the following link, it is very interesting and I am sure
will be very useful

The TX-IR is an 8-pin infrared transmitter IC designed for infrared serial data links , and remote control applications. Data present on the DIN pin is recreated on ...
AVR_Atmega8 (by WLIL)
HI,I'm trying to write a simple programe useing ldmicro language,compile it and download it in the Avr_Atmega8.
.
The problem is the i/p pin has been assigned as normal_open(NO)contac(that means logic 0),when download a hex_file in the chip it appears High.
Secondly,the o/p pin must go logic_high when the i/p pin goes, but it does't , so what is the problem.
Notify me if i miss any steps to configure my test programe and also u can support me by sending any useful documents or vidoes.
I need to trust this ldmicro software because i am responsible in projects involved with embedded systems.
THANK YOU VERY MUCH

On every input You have to put pulldown (wired to minus)resistor 2k2 because AVR internaly are pulled high when no signal on them.
This way when no signal +5V on input input will be 0V same way as LD Micro (POSITIVE LOGIC).

Thanks Jorge Jacome, looked at the link you sent me but I would use a pic as a transmitter and the other as a receiver. do you know if this is possible? I made a ladder program for a tx and rx using serial communication, and works perfectly since electrically connected, I would send it via infrared.

Simom Hello, I just saw what you posted, would the wiring diagram of the RX?

Simom you mounted this control? worked well? now thank you very much.

Thanks Simon, I'll ride this circuit.

Hello Simon, if possible would like to help me understand this program TX.
Simplified so that I can understand.
The PWM is 36kHz with because the receiver operates on this frequency?
What is the purpose of this duty? {Duty: =}
{50} MOV}
Is moving "50" to do what?
Please do not bother with my questions.
I appreciate any help.

duty cycle of the pwm signal output
tx/rx (by Magno Medeiros (Brasil))
Thanks Simon, I understand now that this "50" it is the PWM period.

Goodnight Simon,
I am very grateful for all the help you gave me. after some changes in the program and the hardware could do what I wanted. If possible and if you want to respond, I wonder where I got this help, which country are you from? A friendly hug.
tx/rx (by Magno Medeiros (Brasil))
tx program. I do not know if there is anything unusual but it works ok!

hi Magno
I'm glad I've been helpful.
I'm from Romania and i live in UK.
Have a good day

OK Simon,
Thanks for responding.
