do we have spare cpu time and HW pins to implement CD changer protocol?

Run it twice to confirm. Obviously not using devel version for this...

Change sound settings to 0 (fad, bal, treb, bass) just to be sure this doesn't interfere.
Put on some radio station. Volume around 30% so you don't want to turn it off earlier :D
Leave it on. Radio will turn off itself after 1 hour.

Then you press in center button to really turn it physically off. Then again turn it on.
Notice current volume (should be quieter than previous).
Check sound settings but don't change them. Should be the same 0.

Wait for settings to exit back to radio station. Try increasing sound volume to MAX. Will not be possible.

fixed in

Open sound settings. Change any of them by +1 position. Sound will jump to real MAX.

pin 23 of moto MCU

probably pulses, need to be tested in car ...

Hello, is there approx. time when this chorus1 volume fix hardware could appear in your tindie account? Could it be working for the same age concert1?

HW is ready for this
implement reset of stm32 if reset goes low, or enter sleep or somthing ... or just try wire it directly ...

measure standby current,

• is the resetting circuit working ?
  

• if not implement low power https://github.com/stm32duino/STM32LowPower this will require port to stm32core instead of roger Clarks core ...

create logic to analyze if mute packet is legit or it should be discarded as false mute if buggy mcu set volume to zero = muted audio

after restart of car, looks like something did not catch up.... treble and bass level is not set properly, this need to by probably investigated more complexly to realize if we are sending something to soon, to fast
or we just missing capture of something or we catch everything and just forget to send it to TDA???

investigate if front panel text can be hijacked without spiting HW path between main mcu and front panel,

write documentation with logic

automatic switch to TP while playing from cd changer did not work , nothing come from speakers.
Disabling TP bring volume back where it should be.

using STlink upload or serial bootloader

serial bootloader upload will not be possible for V1 boards

do we have HW resources to implement writing over 3lb using VAGFISWriter?

• probably only after it is rewrite to by interrupt driven :D cose now it's writen using to much delay's....
