Yet another Volume controlers and source selections

[viki_v2]

Hi Danzup,
Lots of good work going on here.
I want to make your volume control + Source selector, But can this be controlled by remote.

Also i have never worked with programming , So request guide on how to program and configure it.I have almost completed my amp. This would be of great help.

thank You

Danzup,

i have bought the same module Jempie has 35 usd
see

Crystal PGA2311 Volume remote control preamplifier kit - eBay (item 200565639023 end time Jan-21-11 22:11:46 PST)

works not OK, can it be changed working with the 8515 chip?
it starts with 46dB instead of 0, and i want to use this as a volume control
but it's an preamp..

Thanks

Just got email from zoe_tsang ,

the firmware is done in the factory so he can give the code
but I ask him to tell them to fix the volume start to memery so it remember last volume settings

so no need for a sample this time, but tanks for the potion

Best Regards

It can be done ,
IF you connect a 10K potmeter with a belt to the potentiometer, then the potmeter to GND (ADC) +5V

The use 1 of the ADC channals to read the volt on the potmeter
and convert it

The adc channel read 0 - 1023 then convert it into a volume db table for read out on lcd

I did not say its easy but it can be done

Framtech
I have an motordrive pot with 2 extra pot one can be use for the
read out the position?

Yes it can via a free adc pin

But ATMEGA8515 dont have ADC ports you need ATMEGA8535 !!!!!

Farmtech,

and connect an encoder with an belt (like Ayre) to the potmeter

hello

I think that last firmware(vu or no vu meter)has a little bug...when you press the button to stand by the LCD turns off...everything ok..but if you turn right or left the encoder the backlight turns on...only backlight(no writing on the LCD) and stays on until you press again the on/off button...what can it be? thank you

 

[dobrivoje]

My suggestion: after pressing standby do not touch encoder.

Hi
Yes I see this now
2 Options disable the encoder or add more code
If Power = off then Power on when encoder it used

My Privat version have power push-button build in encoder
thats why I did not see this smal problem.

I think to disable the encoder during power off is ok...only on/off button should be active during stand by....can you please upload new version of software? Thank You...by the way....JTAG should be disable for all relays to work(danzup told me,after a full night of trying..... ) It is good to know...thanks again

if you read the post in this thread you know that it must be done
Can you try this :
Iam not at my home so dont have the hardware for test
I Disable encoder while power off
This is for ATM16_SHT_R2R_LCD_FARMTECH_NO_VU

Added code for Disable JTAG as hardware code so it works if you forget to disable JTAG
Do not forget to write fusebit : Internal 8 MHz RC oscillator .

hi

It seems that is working well...thank you...perhaps you should modify vu-meter version(for those who want it)...Thank you again
