Analog and audio

Hello.I would like to do the following but since I don't have the necessary skills I ask you. If possible, I prefer to control everything with the keys.I make a list of the functions that I would like to implement:ALARM SECTION- wake up in the morning with a piece of music chosen at random from a list of music files in memory (each time a different music file is chosen. I had thought of a clock radio but I think it is better this way).- daily or weekly alarm programming (i.e. the right to choose on which days the alarm should sound).- automatic update of summer time - winter time- buffer battery in case of power blackout (in this case I think the alarm with buzzer is better to consume little energy and not risk resetting the buffer battery)- alarm disablingAUDIO SECTION- audio player with output that goes to the external I2s DAC.four keys for playback, but I specify that each key corresponds to a single eSINGLE music file. so in all 4 music files, of course they are different from each

I am currently using the HAL function ```HAL_I2S_Receive (I2S_HandleTypeDef * hi2s, uint16_t * pData, uint16_t Size, uint32_t Timeout)```in order to collect an input signal (currently being tested with a function generator 440 Hz sine wave). However, we noticed a couple of things: 1) The data being stored in every index of our uint16_t * pData buffer is radically different. The values do not follow a trend. We expected to see an increase and a decrease in the values as it reads sine wave, however, we just see random values ranging from 0 - (2^16).2) When we stop the signal from the function generator the buffer continues to get filled up. This behavior continues even after unplugging the function generator line from the input to the codec.MCU  - STM32F446RECODEC - PCM3060Why would the values in the buffer continue to be filled up, and why are they not showing a trend that would represent reading a sine wave?A lot of these concepts are new to me so I don't really kno

TDA7577, PIN16 pin is left floating to disable I2C bus mode, the speaker short-circuit fault is detected, PIN14-CD_OUT output is permanently low, and the fault still exists after power-on again, and the speaker is in no sound output protection state. May I ask TDA7577 in the I2C disabled mode, How to clear faults through hardware control and restore normal operation?

I am using a STM32F4 MCU, currently prototyping on a Nucleo-F446RE. I have a PCM3060 audio CODEC to do the analog to digital conversion. I am attempting to use the I2S protocol in order to interface the stm32 chip with the CODEC to process real time audio signals. I have been using stm32CubeIDE to set up the peripherals and their settings.Using I2C, I have configured the CODEC's ADC to act as a master, and the data coming out of it is 24Bit I2S format at 48KHz.On the STM32 side of things, I have the I2S peripheral set up as half-duplex slave receive, data format as 24Bit on a 32Bit data frame, and 48Khz audio frequency. I have been testing with inputting a low-frequency 440Hz sine wave to the codec and try to get some data coming out of the Digital Output pin. I have confirmed that the data coming out is correct by directly sending this ADC data out to the data in of the DAC, and seeing the analog output of the CODEC on an oscilloscope.So far I have been using the HAL_I2S_receive funct

Already i worked in asc ml program but there are some delay to find the word using asc so give some idea to do keyword spotting

How to configure ADC in STEVAL - MKSBOX1v1 (With DMA or W/o DMA)How are the setting to be used for this board. (Clock dividing by ?) - For Audio it will be single channel continuous scanThere are two pins in STEVAL - MKSBOX1V1 MREF and M1P what should I do that in MX and in the firmware functionWhether any firmware logic is there for ADC Microphone if so please share the reference. If I create the [roject it has to work with the code I create, so please share the [rogramming manual for Analog MicrophoneLikeReplySelect as Best

I have tried a few power/ground schemes, series resistance on the ABC lines, etc.Nothing lowers the noise to a usable level.

I have been using STEVAL-IKR002V4D (a daughterboard with SPIRIT1 868 Mhz transceiver) to transmit data. I have it hooked with Raspberry Pi. I have followed the driver library example provided in the design kit software. However, I can't initialize the radio because it seems to stuck in the infinite loop during the VCO calibration. Upon closer examination, I found that the mc_status doesn't change after the command strobe is sent to set a status to lock TX. g_xStatus.MC_State returns 0x03 (Ready), instead of 0x0F (Lock). Do you have suggestion on how to solve this issue?FYI, I can set it to standby, reset or ready without any problem. The problem seems to be exclusively on Lock Tx and Rx.

What will happen with output when input signal is out of "Common mode input voltage range"?Ex.) Vcc=5V (Vicm= 0 to 3.5V) ---> Input IN-=0V, IN+=4V signals Then, Output go to 5V(saturated)?

Hi, How to set STA311 for 2.1 by APWorkbench? for example, ch1 and ch2 mix to ch6 output.

I need to run the TDA7293 because i wont to run 50 volts rails. I am so confused , i thought the parts were pin compatible. I have read the data sheet a few times and don't quite understand what is wrong. I am basically using the schematic of the TDA7294 but plugged into it a TDA7293.ThanksScott

Hi Everyone,Can someone please explain what TAB means for the TDA7388 Audio Amp IC? It's PIN # 1Your help is greatly appreciated!Stay Safe8)

Hello. My name is Dae Hun Hwang from Korea.​I am making Lectenna. (LED + Rectify + Antenna)​I attached my circuit and picture.​Length of my element is about 6cm.​I used normal LED and 1N5711.​I am experimenting at 2.4GHz.​Thank you.​

I use the Bluecoin starter kit to steam the audio by STSW-BCNKT01 software.when using the micro-USB port to connect the PC the output signal does not have a noise signal but using a stereo phono jack port to connect the speaker the output signal has a noise signal.I tested the speakers by having them turn on the music. it hasn't a noise signal.
