Program works good. I have other problem with lcd if I sometimes using volume encoder down on lcd i have this ImageShack® - Online Photo and Video Hosting I'm use two lcd and encoder but the problem is still. Program work fine even if lcd bad work. Draw and put lcd repair problem. Maybe it's by free pins lcd??
Hi
you can try change Waitms 5 in Sub Voldn: & Sub Volup:
to maybe 50 or more , you don't have any wait time for this encoder
maybe thats why your lcd is flipping out
if this don't help , then increase this by 16
$hwstack = 32
$swstack = 30
$framesize = 34

I'm change Waitms and nothing but increase $hwstack = 32 $swstack = 30 $framesize = 34 worse action. I check pcb and connection and all is well. Maybe some other idea?
ok,
what brands/models lcd do you use ?
some cheap lcd's can make strange chars if noice is pick'ed up
try add 2 caps 470pF
from ground to RS , and ground to E pin on the LCD display
maybe this helps you

Hum, finally this one is very close to the one I start building a few months ago and never finished.
Going to dig it out of retirement...
And start working on it.
Farmtech I'm going to need your help because programing is not my cup of tee.

Hi Ric ,
to help I need some info about your hardware setup of cause ,
if you don't like to publish it here send me a PM
also info on how you like to use it
menu input ect
Let me dig it out of my shed, right now I'm selling all of my amplifiers and Cd players (Ebay) to clear out some space to put a small cnc machine in it.
I still have to solder some wires for an extra push button for the menu.
Differences on mine are that I only have 4 input relays and I don't use the PGA2311.

Ok I'm quite confused now....
I was looking for a volume control and input selector solution for my dcb1. Looking essentially for highest sound quality, and had bad experience with light speed (channel imbalance). So started looking at relay/shunt based solutions...
- found the Amb lcduino and delta1/2 board, but they get quite expensive and difficult to source parts in my location (Amb don't offer a kit).
- then found vicol audio kit, which looks promising. However if I read this thread correctly, there are some minor and major issues with the software, which farmtech has tried to solve.
- now I read that farmtech is actually using a Chinese eBay volume controller (no input selection as far as I could tell)
So far i am a confuser if any of the above is a viable and stable option....

I don't think Vicol R2R have issue, except not all rc5 remote supported (fixed in new firmware, CMIIW)
- Farmtech add and modify the software
- It just another vol control to play with, so people have choice which one he/she want to use.

Hi,
vicol audio kit works OK no problems
I was wrong by me to add info for china board here in this topic
it have nothing to do with the vicol audio kit !!!
I know that some of the users here have this china board thats why I put link here to
I only made some "custom change" to vicol audio kit software as as extra funktion thats all
so no problem to get a vicol audio kit

about China board in this Thread
so no one gets confused about it again 🙂

As I am the man who write the vicol-audio firmware I am stated now that there is no problems with vicol-audio firmware !!!!
And I am a bit upset by this allegations. Even in the first version firmware was working perfectly but lacking in some features .
Now we are at 3.5 version of firmware , and on the 1.3 ...1.5 version Farmtech come with some ideas / improvement / features at that time ( 3..2 years ago ) and we exchange some message about some feature that Farmtech suggest and then implemented by him by adding a lot of code for a version which at that time added vu-meter RC5 programmable IR command and text changing name of input channel .
At that time it was for me some oppening eyes as I was not aware that some user want this. Later that year i was again rewriting all the code .
Now in the last firmware ( v3.5 ) there is very little from the collaboration between me and Farmtech (only the subroutine RC5 programming remain (which replace the Bascom native RC5 function ) !!!! THX FARMTECH again for that !!!! ) as everything in firmware is written by me again and again by the years.
As now Farmtech is a dear friend of mine , i thank him for all the job is doing on this thread for tailoring and writing software in Bascom for all users that need it .
(Now I do not have the time that I was sharing for users in those years )
Hope everything is clear now ?
Ok ?
As you see there is no other link / involvement from Farmtech to / with vicol-audio, nor hiding something about this.

Regards last firmware
As allways last firmware for vicol audio R2R controller can be downloaded from :
vicol audio : r-2r volume controller
There you will see the first comercial version ( from autumn 2008 ) v1.0 and last comercial version now 3.5 (today 14.02.2013).
Last version print volume as attenuation in dB from -63 dB to 0 dB.

A preamp case for VICOL AUDIO R2R controller
I'm making a case for the controller i purchased from Tibi a year ago, here are some photos of my progress.
The circuit already tested and working fine, I will post more photos once it's done.

now working on the front panel.
I will use a cd case (transparent cover) cut it to fit the window. I cannot find a shop selling a piece of acrylic, till then a lot of things to do. Will put more photos later.

Hi Kim, wanted to add SI4703 to the TDA7439 code you wrote for me, is it possible since my system is running on 3.3 volts i think we could do it hardware wise. no problems yet
need you to match the two codes. in to one. 🙂

and yes. tda7439 is on 5 volts but i do have P82B96 so i dont think we should have problem with level shifting i2c. and i remember you ahd also ordered those ic's last year right. along with the SI4703 board from sparkfun.
Hi,
Yes it run 3.3V via levelshift
