very understandable. i guess i suck somewhat less at coding than you. i am ahead of you by about 4K lines of code but those lines of code encompass the workings of a complete remote controlled radio/stereo/media player.
the GUI/sw is what makes it tick, has appeal, adds functionality, makes everyone different.
and i am willing to give the code away for free if everybody is on side. if not everyone cobbles together there own contraption with what ever nuts and bolts you have on hand.
nothing wrong with that either, if that is what you chose to do and $ are tight.
sure that is why a next gen GUI is a ft800!! in the diy world.
good luck programming a lcd touch screen.
a touch screen interface can be come very cumbersome and confusing if you have lots of features, with menus buried deep.
a touch screen for volume control = yuk
my portable is simple, channel selector, volume, freq/fav station, display what ever you want.
i am i the midst of designing a radio/alarm clock for my mother, the gui is as simple as it can gets, probably a 2 line display to keep the size down, but if someone is hard of seeing, you want a big display too, maybe a 4x20 will be the best for mother.
It's hard the beat big old LED 7 segment displays for anyone with vision problems. I use them for shop equipment I need to see quickly from a distance. All the DROs on my machines are LED. There's usually so much coolant stuck on them you would never see LCD.
i am carrying my pre-amp conversations in this thread
sure, i studied jal compiler, wrote some of it too when i was thinking of using a pic. i changed mcu to xmega, so jal, was of no use to me anymore. i took some of the useful coding bits and ported them over to bascom-avr.
see attached some of the a/d pre-amp front, rear panel concepts. have to say i would do it differently now!!
that is good to know that you built that hardware.

HDMI/DSP yet more complication to the equation. if you want less heat go with TPA3116/8 as your surround channel amps.
yes, that is an option as well. i run the 4 line lcd in big screen mode too, the characters are almost 2" high.

The big LCD is a nicer looking option for sure.
Multi channels with lots of options get really busy quick! The last attachment isn't working. I draw everything in Corel Draw, then build it from there. There will likely be a Solidworks guru pop up now and tell me I'm doing it wrong but I can have it drawn up and on the mill before they have their page set up. I have a pretty well equipped machine shop. I get all the lettering done either in stickers or lazer etched. The guy who owns our graphics shop did Tony Stewarts pit crew helmets a few years ago. He's very talented with an air brush. I deal regularly with automotive painters and powder coaters too. Chassis are fun for me.
I've actually been planning on using Valery's CFA-CFPx2 for rear and center channels. They run stone cold and sound amazing.

attachments should work now i re-loaded them and checked again.
i used front panel designer/express, as i was planning on using them, but they are expensive. the s/w i do like, it is easier than say a real mech cad pkg.
nice to know you have excellent machining capabilities to your disposal, i have a drill press and some files
sure if valery's design fit the bill = great.
the tpa3116 design(s) can save a ton of space/heat/$ for a multi-channel amp. although many balk at class "D" ie. OS?
everything has a place and you do not know until you try.

Really, anything works for designing. Basic PC board programs will give you XY positions good enough to mill off of and a good idea of what the finished product will look like.
I'm not a class D fan either. My midrange hearing is damaged but my high frequency hearing is still excellent. Class D seems harsh to me.

if I gave you a hex file are you able to program it into the pic?
let me investigate, it has been a while ago.
okay, the code you want to change is in "init_vv.jal file. as you can see or count the characters, it is a 16x2 display
i suggest to you
1) start a new thread and we can discuss it there
2) lets work on getting you the dev tools up and going, so that you can change as many things as you would like.

So you use "raw code" instead of some proprietary one (arduino).
Whoa ... I think this is actually the same company that supplied the
DOS software at my old factory job.
This stuff runs more with less , polls the hardware.
PS - for those that don't know ... the basic is like a 100K program
in C that needs nothing (small and compact) vs. a Java-like one
that needs a big external library (dependent on everything).
Oh no , the xmega IC ... could I solder that ?? I'm not as young
anymore.

A srynge of solder paste and a toaster over can solder almost anything. The trick is figuring out how much paste to put on but usually you need more than you think.
raw code? hum no, i wrote the code in basic "bascom-avr". i use a small bit of asm code for the low level lcd control functions.
Home - MCS Electronics ?
sure you can, it is only 0.8mm pitch in 44 pin pkg
= piece of cake, std soic is 1.27mm pitch. i can help if you have difficulties with a xmega soldering or programming.when I remember designing with hc05/hc11/8051 what a PITA, esp if you are a code hacker like me.
that is exactly what i did with the portable, bottom row for display of menus over the 6 bourns encoders with builtin switches and bi-color leds, covers a lot of bases and makes for ease of use. without this ability the gui is nuts, i have a separate menu for the different functions, AM, FM, MP3 player, USB dac/codec. look a the tons of buttons on the a/d preamp = nuts, many done away with intelligent /dynamic menus

Not quite like you Rsavas !
I had no problem reverse engineering my 1k arduino code.
Arduino is for dummies , everything in the environment is setup for
their dev boards.
Way bigger learning curve with the AVR (by raw , I meant basic like)
Whoa.
It looks like they did the clock with a WYSIWYG GUI. Too bad there is
not one of these for pre-amp controllers. But who has preamps ?
walmart don't
Wiznet - ahh, clock connects to the www.

If you think that is funny
Here is our pre-amp schematic (below) -
Board layout at 1mhz is not like at 100mhz , check out the "snakes" on
a PC motherboard.
