HelloI'm going to use BLE to make a Bluetooth speaker that is connected to a cell phone.As far as I know, I need to use I2S to use audio output, is there an MCU that supports BLE and I2S communication?And can I know an example or something to refer t...
Hello,I have a PDM MEMS microphone that I am reading in I2S master receive mode. I am trying to take this data and put it in a FIFO buffer and then output the data over UART using DMA. I must be confusing the buffer sizes because I get mostly zeros...
STM32F4-DISCOVERY board: I need to read from the mic (MP45DT02) and I was trying to use the STM32CubeIDE to generate the initialization and I cannot get to enable the pdm2pcm middleware. I have tried to configure I2S2 (no errors) but still pcm2pcm is...
Is there any working example to do USB Audio Recording using the STM32F0? I need to send audio received by the I2S port on the STM32F0 and send it out to the host PC via USB. I have seen AN4711 and also have the Record working on the F7 with the hel...
I am using stm32 cube mx and keil. I am trying it using i2s3 in master mode and dma but it is giving wrong inputs. Please help me.
Hi there,I'm designing a PCB which will feed audio at 48KHz / 96KHz / 192KHz to a DAC over I2S (TI PCM5242).I'd quite like the option to have USB - in an ideal world, USB Audio, but at the very least a COM port (USB device).For the DAC, I'd need an H...
I've got an audio codec chip with bidirectional i2s interface, but I can't find any examples or any other info on configuring bidirectional i2s through SAI and HAL in stm32 microcontrollers. I am able to configure single-direction i2s just fine. How ...
Hello,I am sampling audio data with sampling rate 16 kHz and then send it using RF to the other MCU which is sending to DAC samples with the same 16 kHz sampling rate, Im using DMA for sending data through I2S to external DAC. The problem is that the...
Is there any example walking thru how to convert a .wav file of the audio to play on STM32F429?
Hi there!When I set up a fresh project for the STM32G431KB in STM32CubeIDE, let's say I want the SAI to be clocked by an external clock source.So, in the prefs, I set Audio Clock Input (I2S_CKIN):Then I set up my Clock Configuration:Now one would exp...
