Hi Fotios

Great project, have watched for a while but have now decided to add to my pre-amp.

I only really want vol up / down and maybe the mute function as I will be using the remote from my trusty old Arcam Alpha 7 CD player which has these amp functions on the CD remote

My question, could I use this Infrared Receiver Buy IR Remote Receiver IR Receiver Module 36kHz Vishay TSOP31236 online from RS for next day delivery. as both variations of the TSOP34836 are on backorder with no delivery date advised, specs seem close enough, can you see any issues?

Cheers
Dagwood

Hi Dagwood
Of course you could use TSOP31236 instead the original 34836, both IR receiver ICs are similar and operate in same 36KHz frequency, viewing angle also is same 90 deg for both, etc. JUST BE CAREFULL REGARDING PINOUTS BECAUSE ARE DIFFERENT! Please study the PDF DATA SHEET of each one IR receiver IC, pinout is refered in the picture at the top of the corresponding "pdf" doc.
Cheers and good luck

I used the TSOP31236

here is what I wrote to Fotios:
Anyway, the RC5 Volume control is really great. I have the Vishay 36 Khz IR Receiver on two meters of shielded cable. The range is amazing. Anywhere in a (70 Sq Meter) room in any direction bouncing off 5 walls works just fine. The circuit also works great with 40 Khz diodes, but not as good as the 36 Khz.

Thank you so much for your precious report!
You are very kind

Hi Fotios

Ok, we are up and running....sort of

I will get some photos up shortly

The issue I have is that VR1 only turns in one direction and the mute relay will not work either with the remote or with SW1. I have not connected a relay to the power / standby connection as its not needed for my appliction.

I have used FCv5.HEX

Any thoughts?

Cheers

Hi Dagwood.
First of all check carefully your hardware for any possible mistake. The FCv5.hex file you use (MOT_POT_RC5_FCv5.hex, right?), is configured for PIC16F88 microcontroller. Make sure that you use the same micro. You must use the command "Import File" of the assembler of your programming device, if you use "Open File" will loss the microcontroller configuration bits (osc. frequency etc).
Please let me know.

Hi Fotis

Thanks for the quick reply

I am using PIC18F88 with MOT_POT_RC5_FCv5.hex

I tried to re-load the file ( I'm using PICpgm programmer ) selected "load Hex File" rather than just opening the file but still the same issues.

The only other changes I made was to use different transistors
MPSA06, I used BC546 (now swapped around as pinout is opposit)
MPS2222, I used BC337 (now swapped around as pinout is opposit)

?????

Hi Dag
You refer PIC18F88 and i am sure that is a typing error of yours, you mean PIC16F88. OK, your micro is correct. I don't know (i will look on the web for it) your programmer "PICpgm", i just use two programmers the Matrix Multimedia EB006 and the Microchip ICD2. Both ICD2 and PICKIT2 (or the recent PICKIT3) programmers are managed by MPLAB ICD software and for this was my reference "use Import File and not Open File command". But i think "Load File" command of your programmer is the same with "Import File". Well, i will try again to program a PIC16F88 with ICD2 and with the HEX file i have uploaded in Matrix Multimedia forum (NOT this stored in my PC!)and i will confirm you if the file works correctly.
Transistor substitution you did is not problem, your transistors are OK.
Stay tuned.
Fotis

OK Dag
Just now i dowmloaded the "MOT_POT_RC5_FCv5.hex" file from Matrix Multimedia forum, i imported the file in MPLAB IDE and i programmed a P16F88 with Microchip "MPLAB ICD2" programmer. Then i installed the P16F88 in the ready "Remotelly Controlled Motorized Volume Pot" test board that i have and i've tried it with 3 different RC5 remote control handsets, the first transmits in RC5 TV address = 0, the second in RC5 Preamplifier 1 = 16 and the third in RC5 Preamplifier 2 = 19. I can confirm you that with any handset the "remote controll mot mot" circuit works just fine without any mistake. The HEX file you downladed is correct. Your problem must be in your hardware, please check it thoroughly. Some times, e.g. a bad solder or a deffective switch could cause problems.
Please let me know.
Fotis

Hmm... have you tried the PICpgm programmer with any other project? I have seen it for first time. I don't knew it. If you are sure that PICpgm is working OK, then continue your search on your PCB, there must be something wrong. Either deffective device or error in mounting. Check 1N4002 diodes if are soldered in correct direction. You could use two LEDs with 470Ω drop down resistors, instead relays to check if STBY and MUTE outputs work OK. Check your hardware again. "LK" marked components actually are simple wire links.
If you still have problems, you could post me a e-mail in eal@dra.forthnet.gr with your address to post you a ready programmed and tested micro for free. It is not problem, the cost is just of 2 beers .
