Yet another Volume controlers and source selections

[aditya]

i want to remove menu optin and make it jsut toggle switch for input selection how to do it, such that at what ever the volume the chip maybe , i can just click the button and toggle between the input channels. thanks a lot for all the help, with warm regards aditya

Currently i use also an simpler programmer like this (beside my old STK 500) :

and I use for 6 years also this programmer :

Yes the device must be powered for programming with or without volume board attached .

Do not forget to write fusebit : disable Jtag , Internal 8 MHz RC oscillator .

Fantastic! Thank you for the information.

I've costed the BoM up here in the UK through Farnell and RS is anyone's interested.

I'm in the process of moving house at the moment so the build is going to have to wait

Cheers

As a request from some users here are the files for tda7318 + atmega8515 project :

cool we can also use TDA7313 with this routine coolll , how about a rotary encoder, for volume , and auto return to a basic screen after the function has taken place,
this is great, tc

I found here some usefull info about encoders Drehencoder - RN-Wissen

And there are even code exampels in Bascom.I hope this helps.

And here is info for 2 encoders + 4 buttons via I2C expander (PDF)

thats a nice option kim, i m not sure how much do those TI parts cost in this side of the world, samples always are free but still,
I m assembling my amp with the pga2310 file you last up dated,
will let you know how it works, tooo freaking much of wireing and i m going to sit on a sunday to re do the board, wiht onboard regulators and pga

hii i m having some issue , i think i m wrong some where .. that is, that i m using pga2311 in the board and i connected the processor to it, and had forgoten to pull up the zce pin (1) and my chip had heated up bad ly, and now that i fixed it,
1) there is no control on volume it just comes at some high gain,
2) the display in between goes corrupt, it never happend when i was elektor issued articles program, using pga 2311 and pic18f452,

[Leon08]

This cannot be because of zce pin.It must have another cause.

the problem is that when i turn on it go up at full volume and when i turn the knob i get click sound of the encoder, no matter what the lcd shows i have full volume, and i dont know what to do, going nuts,
it didnt happen when i was using elektor electronics project file it worked like a dream
