Hi,   I want to record some audio signals using your Evaluation Kit STEVAL-MKI126V1 + MKI129V3 connected to my laptop through the MKI138V1. I've installed APWorkbench on Windows 64bit running on Parallels Desktop. How to stored data coming from six microphone (2 on board from STEVAL-MKI126V1 + 4 on STEVAL-MKI129V1)? What I needed is six… (Show more)

hi all,   this nice AMP IC is quite easy to setup and switch on trough i2c. Diagnostic to check for speaker in short, open etc, is available trough i2c before i2c amp stage power up, and should be still available also after power up.   Btw, once amp stage has been powered up with diag bit enabled, i get always the same 4 bytes diag info, even… (Show more)

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)

I'm using a simple capacitance to frequency converter with a ts555 to measure water level. After installation, I notice a large drift, so I returned the circuit to the lab to diagnose the problem. To eliminate the sensor as source of problem, I replaced it with a fixed (stable) value.   The drift seemed temperature related, so I tried to change… (Show more)

Hi. I designed a PCB to use stm32f407 and TLV320AIC12 codec for capturing and playing sound. As you can see I connected I2S pin of stm to tlv in this way:   STM32F407                   TLV320AIC12 CK---------------------------->SCLK WS--------------------------->FS ext_SD---------------------->Dout SD---------------------------->Din… (Show more)

Hi at all,   I wanted to order a sample product to try to build up a own bluetooth box. After I send my request, it shows your order has succesfully created but I can't see it in the order history. After I close the tab, it shows the items in the chart again.

I can use one SAI RxTx channel  or Two separate SAI ports,  providing independent Rx and Tx channels.   Which solution supplies the best HD stereo audio quality ? (stereo and bass channel would be great)   The Speaker drive can be separated from the Audio codec but I am all ears on any suggestions.   My processor board is based on the STM32F7… (Show more)
