Hello,I'm looking for a simplest solution for encoding 1 channel audio.Ideally at input - signal from microphone, ADC - not necessary high-end (10...12bit sufficient), output - S/PDIF. Does exist an IC that integrates whole this stuff ?Thanks.
Hey,I am trying to send some sine wave signal over usb audio class to computer. I arranged usb descriptors so computer recognizes mcu as microphone but I am struggling to send sine wave. I create sine wave with dac and I read it with adc. what should...
Dear all,I wanted to develop a USB Power Delivery SINK project using my STM32G431KBU3 MCU.For that reason, I have designed a custom PCB and follwed carefully ST's WiKi:https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:STM32_Advance_USB-Power_Delivery...
I'm trying to make a guitar pedal using the ADC on my F767ZI. I want to be able to perform an FFT and other functions on a buffer of data sampled at 48kHz.I wanted to use the ADC DMAs and use the equation Tconv = 12.5cycles + SampleTime, but I have n...
Does the ADC need to be initialized in a special way for the USBPD stack to work properly?I am trying to implement PD on a STM32G431 and the USBPD stack doesn't seem to work. If a powersource is connected, the CAD state changes to ATTACHED but then i...
Hello,I'm getting values from an ADC an ACC, and a microphone. The ACC and ADC are in continuous acquiring mode but with different sampling rates. The microphone is turned on after a random trigger in time, basically the microphone record data for 1 ...
In this case i am wondering if the STM32F767ZI ADC is sufficient for sampling audio with the frequency range of 20-40kHz?
Hi, i am currently trying to make the ADC driver code for the stm32f3 version of the colorchord https://github.com/cnlohr/colorchord code work on an stm32f4, as my F4 does not have an on board microphone, also, i still want to use direct audio-line-i...
hy,I would like to use your NUCLEO-F446RE board platform with X-NUCLEO-CCA01M1 and X-NUCLEO-CCA02M1 expansion board, using the FP-AUD-SMARTMIC1 software.In reality we have a configuration like the figure in the annexwhere external codecs are not used...
Posted on October 13, 2017 at 00:02I 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...
