A1S Audiokit with V3.01b

[steevemadison75]

Hi , the last working version that work on my A1S Audiokit is v2.17 , i tried yesterday to compile your new version with visual code and i get " no space left on device " , if i remember the audiokit has 4MB flash and 4MB psram , i did setup my platform.ini as usual , (same config on v2.17) board_build.partitions = boards/miniwebradio4MB.csv ; 4MB Flash board = ESP32-Dev-4MB ; 4MB Flash

i tried to comment AC101.h and WM8978.h in common.h to not use those library , i also put -1 on all bluetooth BT_EMITTER_ as i dont have this module , i even tried to comment the KCX_BT_Emitter.h , by doing this i get compilation error so i uncomment it

did find one version of the V3 that i could compile , it look like it worked , but i get garbage sound , (similar to a FM radio not on station)

got any clue ??

PS im not new at your webradio , i was one of the first to use a rasberry tft , and you help me to calibrate the screen and i request some function in the web search by tag search

thank for your work

Hi @steevemadison75, probably in Arduino V3 there is no default for the I2C frequency. I have now manually entered the 400KHz that used to be set automatically. My AI Thinker board with AC101 is now working. These are the values in common.h:

#ifdef CONFIG_IDF_TARGET_ESP32
    // Digital I/O used
        #define TFT_CS 22
        #define TFT_DC 5
        #define TFT_BL -1
        #define TP_IRQ 12
        #define TP_CS 13
        #define SD_MMC_D0 2 // cannot be changed
        #define SD_MMC_CLK 14 // cannot be changed
        #define SD_MMC_CMD 15 // cannot be changed
        #define IR_PIN -1
        #define TFT_MOSI 23 // TFT and TP (VSPI)
        #define TFT_MISO 19 // TFT and TP (VSPI)
        #define TFT_SCK 18 // TFT and TP (VSPI)

        #define I2S_DOUT 25 // pin 25 AC101, pin 26 ES8388
        #define I2S_DIN 35 // pin not used
        #define I2S_BCLK 27
        #define I2S_LRC 26  // pin 26 AC101, pin 25 ES8388
        #define I2S_MCLK 0

        #define I2C_DATA 33
        #define I2C_CLK 32
        #define SD_DETECT 34 // some pins on special boards: Lyra, Olimex, A1S ...
        #define HP_DETECT 39
        #define AMP_ENABLED 21

        #define BT_EMITTER_RX    -1  // TX pin - KCX Bluetooth Transmitter (-1 if not available)
        #define BT_EMITTER_TX    -1  // RX pin - KCX Bluetooth Transmitter (-1 if not available)
        #define BT_EMITTER_LINK  -1  // high if connected                  (-1 if not available)
        #define BT_EMITTER_MODE  -1  // high transmit - low receive        (-1 if not available)
#endif

If you have the new board with ES8388 you have to change it a bit. And yes, the board has 4MB FLASH and PSRAM, please perform a "Full Clean" beforehand so that the libraries are fetched again. The BT_Emitter triggered a click every second, this has now also been eliminated.

hi , i was able to compile 3.01c and it work , the audiokit i have is the new one with ES8388 , but i found that some station that is running at 320k stutter and on v2.17 the same channel don't stutter at all , beside that everything work as usual

[schreibfaul1]

Yes, unfortunately that is the case at the moment. We are still using a pre-compiled Arduino version. Once the bugs have been fixed and settings can be made via menuconfig again, the WiFi data throughput will be the same as with version 2.

[steevemadison75]

oh , ok , thank's for your time , i'll wait for a fix at later time , keep up the good work.

P.S i'm using your radio everyday and i really enjoy it
