Brymen IR connection protocol - Anyone sniffed it yet?

--- Quote from: Sairus on June 22, 2016, 06:21:07 pm ---I have not turned the original idea so I did everything from scratch.
I made a cable to the microcontroller and wrote a program
(Temporarily not possible to build charts but the program itself is quite functional)
On further development, I will write here.
In the help tab of software is a description how to make your cable.

Wow, that looks great! Such a simple circuit design too. The software looks actually quite good, I like the interface. Thank you for taking the time to write the documentation on the software and circuit.
I did get a few unhandled exceptions while I was playing around with the software (never actually had a DMM connected), but otherwise looks good.
I assume that you made the PCB yourself using acid etching?

I apologize for my clumsy English in PDF.I have tried to write all the necessary information to create your own cable,repeat my design is not necessary.Initially, I did everything for myself but then I thought that if I share software that i can really save time for others people.

I found bug fix it. this is a beta version and sometimes shit happens ))) but it usually happens when you open port / closed port during operation, it seems stable.

photoresist + FeCl3 (initially I cut a suitable piece of board then drilled holes and then made a placement of elements.)

Wow, Sairus, that is really great work! Nice Job! :clap:
1) I downloaded your GUI and it launched just fine. I have not tried connecting my DMM, because I am still working on my interface cable.
2) As I am familiar with PICs and have the 12F683 on hand, I will be using your design. I will be setting up your circuit on an Eagle PCB Board (like I did with Jadew's design,) for myself. Now that I have the board sized correctly, it is very easy to put different circuits onto it. It is very cheap and easy to have board's professionally made, once the Eagle files have been developed.
I have been notified by OSH Park that my final revision of Jadew's board has been mailed to me. They should arrive no later than Monday, I would think. I will assemble one, verify everything and, then, post those Eagle Files. I will do the same thing for Sairus's design, in the future.
t1d:
- Attached is Sairus's schematic as a jpeg, for ease of use.
- As Sairus's PIC12F683 controller requires an USB interface and my PIC18F4550 controller platform already has the USB interface, I will stay with using my controller platform. However, I will be continuing to make the Eagle files for Sairus's beautiful little circuit.
@ Sairus
- May I have a Bill of Materials for your circuit, please? It would really help me to select the proper footprints for the components that you use in you design. Or, just give me the sizes of the passive components...
- May we please have your source code for both the PIC12F683 (this would really help me configure the PIC18F4550, for this application) and your GUI?
- Would someone please review my IR test Circuit at Post #105 and tell me if there are any errors? If it is easier to just propose a complete test circuit of your own design, that would be fine... I just need an easy way to test in-circuit IR component functionality, without having to complete the firmware coding.
Thanks for the help...

actually not,my software work with serial port so it not necessary use usb (uart usb adapter).You can use max232 and connect device straight to RS232,or use bluetooth module and make wireless connection. Potentially you can use esp8266 to use wifi connection.

I use what i found in my mini stock /R1 R2 C2 smd 1206/ u1 pic12f683 soic8/C1 just tantalum capacitor/ in my design not so many components so thruhole components fine too :-//

GUI is not finished I work at graphs part,for now i prefer not share source code is need some tweaks. For PIC i use microC PRO for PIC i not sure that you can use my code but i have PIC18F4550 so i can make hex file for you.
