Hi,  i have  a strange problem in using SAI in I2S mode. I hava DA7212 codec connected to STM32F479NI, SAI is configured in slave rx tx mode. When i use DSP mode it works perfect, i can make a loop - receive data from microphone (SAIA) and send it back to codec (SAIB) using simple: HAL_SAI_Receive_DMA(&hsai_BlockA1, (uint8_t… (Show more)

hello!I am new to this forum. All of us, except the deaf, hear a wide variety of sounds.  The most amazing thing I think is dolphins. They can not only make the sounds we hear, they can make and hear what we can not hear.I want to know what the sound of the dolphin sounds we can not hear.

Hi.     I'm trying to output 24khz mono pcm data over SAI to wm8994 codec. 16khz mono seems to work OK, but 24 is not supported by ST by default. I've made some changes for the support to codec and sai init. Now I wonder what else needs to be changed.   As baseline I've let the clock configurators use same clock paths as 48khz (44 vs 48 khz… (Show more)

I am able to sense voltage from the ADC3 pin of SensorTile, when the sensortile is on the Eval board (STLCX01V1). The ADC output changes with change in external supply voltage. But when I solder the same sensortile on the cradle board (STLCR01V1), it stops sensing any change in voltage and gives me 0. Is there a special function for enabling ADC… (Show more)

Hello ,I'm trying to connect Adafruit microphone using SAI of the STM32L4. This microphone uses I2S protocol, and delivers as output PCM 24 bits data,(The microphone includes Segma delta filter and a decimator which are used to convert PDM data to PCM data), over sampling rate fixed at 64 and Clock frequencies from 2.048Mhz to 4.096MHz are… (Show more)

Hello Community, Does the SAI sub-block clock source matter when it is in Synchronous Slave mode with the other sub-block? In other words, should the two sub-blocks have the same clock source? Thank you.

I want to generate simple audio waveforms and send them out through the headphone jack, preferrably using a synchronous interface such as HAL_SAI_Transmit. (I know there are better/more efficient ways to do this which don't peg the CPU, but I just want to keep it simple to start off).   Are there any good resources (especially example code!)… (Show more)

Greetings I'm currently looking for a spice model of the L7805CV 5V Regulator for my design simulation , I've looked on the product page and keep seem to find anything . Is there anyone who can point me in the right direction?

Hi     I am trying to build an announcement system using TDA7491P audio CLASS D amplifier. I am not able to figure out how to control the volume of the speakers using the amplifier.

I am trying to read back I2C registers on the TDA7419 audio processor to verify their contents.  I've try both standard I2C register reads as well as the custom method on Page 29 of the datasheet (rev7).  In all cases, a NACK is received and no data is transmitted.   Does register read-back work on the TDA7419.  If so, does anyone have an… (Show more)
