port to stm32

[cosmicAquarius]

I, I just started to use that wonderfull library with esp32. but the adc of the esp32 is not very good. I am just trying to port the lib to the stm32 wich is not tested or supported.
Since I am not sure yet, I think this involve to disable the ethernet support.

I tried this build flags :

build_flags = -D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC -D USBCON DCORE_DEBUG_LEVEL=5 -Wno-unused-variable -Wno-unused-but-set-variable -Wno-unused-function -Wno-format-extra-args -D USE_ETHERNET=0 -D USE_URL_ARDUINO=0 -D USE_AUDIO_SERVER=0 -D USE_URL_ARDUINO=0 -D STM32 -I lib/

but I keep getting this compilation error :
In file included from .pio/libdeps/blackpill_f411ce/audio-tools/src/AudioTools/CoreAudio/AudioHttp/AudioHttp.h:9, from .pio/libdeps/blackpill_f411ce/audio-tools/src/AudioTools/CoreAudio/AudioPlayer.h:5, from .pio/libdeps/blackpill_f411ce/audio-tools/src/AudioTools/CoreAudio.h:17, from .pio/libdeps/blackpill_f411ce/audio-tools/src/AudioTools.h:74: .pio/libdeps/blackpill_f411ce/audio-tools/src/AudioTools/CoreAudio/AudioHttp/AudioServer.h:15:12: fatal error: Ethernet.h: No such file or directory

Am in in the right path or should we, modify the define list and the code to make it work, I'am not sure to measure the work to achieve yet

I guess you will need to figure out what PlatformIO does wrong: There is no problem in Arduino¨

Did you follow the instructions in the Wiki ?

[cosmicAquarius]

this is a good start. and a very good news :) For sure I will read the wiki again. I have not yet read all the code of your lib, but wow what have read yet is wonderfull there is so much thing to explore ! that is amazing what a wonderfull job you done ! there all the universe of sound in that lib mozzi maximilian the wonderfull polyphonic class Syntethizer I discoverd it after i start to build my own class to get polyphony "already defined" so I started to read the code. And that is one of my best read :) Thanks for all Pschatzmann

[cosmicAquarius]

my code is not good at all for now since I am testing, but for sure I will provide a pull request with good exemples of use soon (after review)

[pschatzmann]

Maybe google how to make Ethernet available via PlatformIO.
A second place to check is the processor specific settings in AudioToolsConfig.h: if something is not fitting with your project you can try to override it with build_flags

[cosmicAquarius]

here is the problem maybe

#ifdef STM32
#define USE_I2S
#define USE_PWM
#define USE_TIMER
#define USE_ANALOG
#define USE_ANALOG_ARDUINO
#define USE_INT24_FROM_INT

#define PIN_ANALOG_START PA0
#define PIN_PWM_START PA0
#define PWM_DEFAULT_TIMER TIM2
#define PWM_FREQ_TIMER_NO 3
#define USE_SD_NO_NS

#define PIN_I2S_BCK -1
#define PIN_I2S_WS -1
#define PIN_I2S_DATA_IN -1
#define PIN_I2S_DATA_OUT -1
#define PIN_I2S_MUTE -1
#define SOFT_MUTE_VALUE 0
#define PIN_CS -1

#define USE_ETHERNET
#define USE_URL_ARDUINO
#define USE_AUDIO_SERVER


#endif

STM32 doesnt have wifi by default (black pill stm32F411)

build_flags =
-D PIO_FRAMEWORK_ARDUINO_ENABLE_CDC
-D USBCON
-D USE_ETHERNET=0
-Wno-unused-variable
-Wno-unused-but-set-variable
-Wno-unused-function
-Wno-format-extra-args
-DCORE_DEBUG_LEVEL=2
-I lib/

What am I doing wrong ?

[pschatzmann]

Just google how to include the Ethernet library in PlatformIO: This e.g. gives this as result

[cosmicAquarius]

oh my bad damn ! sometimes I can forget the basis shame on me :), here is the complete working setup for a working project in platefoorm io for stm32f411 black pill with i2s driver. Thanks god I finally found your repository. I will finally be able to build something good from there.
I went through all kind of problems with this ide :)

Would you appreciate a Pr request to add this to the wiki ?

For the ones coming here because they know how to use google...(the basis) be aware that plateformio does not everytime regenerate the .pio, so you have to rm -rf .pio/* then restart vscode

thanks for your help and the massive work you have done so far : foor exemple that repository
