Hi,I'm developing an USB-C sink, using dead battery feature.I have respective CCx pins connected to DBCCx pins and the source can successfully power the sink.However, when the UCPD code starts running, the source disconects the 5V, effectively result...
The examples only support the digital MEMS microphones on the board. I'm uncertain whether the BSP actually supports using analog in. The wm8994.c driver supports analog in, but I'm not certain this function is actually being called by the higher abs...
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...
Hi,Greetings!Wondering whether the following logic works:Configure TIM7 for a sampling rate of 48khz. TIM7 triggers DMA to fetch audio samples at this rate, dumps it into the DAC buffer.Is this the right path ?If so, how to go about with the dual cha...
Hello!I have a education task. I need to transfer X-CUBE-USB-AUDIO (https://www.st.com/en/embedded-software/x-cube-usb-audio.html) to stm32f746g discovery. Project supports boards STM32446E-EVAL and 32F769IDISCOVERY. I think stm32f746g is similar 32F...
When I try to using STM32CubeMonitor-UCPD software with X-CUBE-USB-PD and ON-FUSB3-STM32, VCP does not appear on the laptop. I cannot see any connected board on the software.I already installed STM32CubeMonitor-UCPD and USB driver for ST-LINK.And, do...
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...
Hi, I have gone through below link. https://community.st.com/s/question/0D50X0000AIcIc6SQF/audio-player-demo-stm32l4r9idisco?t=1604201466282Is there any demo for audio player from that audio files pop up from USB Mass Storage/SDCard in TouchGFX...
