Quite some time ago, I started to look into the STM32F411 Discovery Kit with Arduino<\/a>. Unfortunatly the audio codec i2c address<\/strong> was not showing up in the port scan. I found out that the chip needs to be activated<\/strong> with<\/p>\n

setPinMode(PD4, OUTPUT);\ndigitalWrite(PD4, HIGH);\n<\/code><\/pre>\n
One of the reasons why I started my arduino-audio-driver<\/a> project, was that I wanted to have a clean API for the LQFP100<\/strong> audio chip that is provided by this board. So I added driver logic and the following pin definitions to the project:<\/p>\n
    \/\/ add i2c codec pins: scl, sda, port, frequency\n    addI2C(PinFunction::CODEC, PB6, PB9);\n    \/\/ add i2s pins: mclk, bck, ws,data_out, data_in ,(port)\n    addI2S(PinFunction::CODEC, PC7, PC10, PA4, PC3, PC12);\n\n    \/\/ add other pins\n    addPin(PinFunction::KEY, PA0, PinLogic::Output);     \/\/ user button\n    addPin(PinFunction::LED, PD12, PinLogic::Output, 0); \/\/ green\n    addPin(PinFunction::LED, PD5, PinLogic::Output, 1);  \/\/ red\n    addPin(PinFunction::LED, PD13, PinLogic::Output, 2); \/\/ orange\n    addPin(PinFunction::LED, PD14, PinLogic::Output, 3); \/\/ red\n    addPin(PinFunction::LED, PD15, PinLogic::Output, 4); \/\/ blue\n    addPin(PinFunction::PA, PD4, PinLogic::Output); \/\/ reset pin (active high)\n<\/code><\/pre>\n
I finally managed to to have this piece working. Here is the Arduino Sketch which sets up the audio chip with the default settings (44100 samples per second, 16 bits) – because no parameter have been defined:<\/p>\n
#include \"AudioBoard.h\"\n\nAudioBoard board(STM32F411Disco); \/\/ CS43l22\n\nvoid setup() {\n  LOGLEVEL_AUDIODRIVER = AudioDriverDebug;\n  Serial.begin(115200);\n  while(!Serial);\n  Serial.println(\"setup...\");\n\n  board.begin();\n\n  Serial.println(\"board has started\");\n}\n\nvoid loop() {}\n<\/code><\/pre>\n
And here is the related output<\/p>\n
