Inquiries regarding spiritDSP.We are implementing mp3 with DAC DMA using SpiritDSP.The time to play depends on the samplerate and bitrate of the mp3 file.The original time is 3 minutes and 10 seconds,The playback time is different as shown below.The ...
I'm having problems with the PDM2PCM lib and am getting desperate.I have a STM32L151 with an external clock source of 8.192 MHz. The SYSCLK runs with 16.384 MHz. The APB2 (SPI1) runs with 4.096 MHz.I'm sampling a PDM mic with an 8-bit SPI at 2.048 MH...
I am working with demo board STM32G474E-EVAL and try to run example project in which board works in Source mode.When I connect the power bank (HyperJuice Power Bank 130W USB-C) to the USB-C, the board starts constantly sending messages about its capa...
1) Is the STM32 capable of handling multiple audio codecs for audio transmission over USB?2) If so, what development boards would you recommend for getting familiar with it?3) Are there any tutorials for setup? Thanks!!!
I have been using STM32G MCUs with USB PD Sink or Source application. Right now, I want to implement Debug Accessory Mode in either STM32G0 or G4 MCUs with SInk USB PD Application. Hence, i would like to use USB-C cable SBU and Data lines for MCU fla...
Hi,I've some trouble with the NUCLEO-L552ZE-Q using USB PD.I'm using the "USB-PD_Consumer_1port" example with STM32CubeMonitor-UCPD and can't request any power profile (see image below). I also tried different power adapters.Did I forget something?Ho...
I am working with demo board B-G474E-DPOW1 and studying USB PD.Is it possible for this board to operate in Source mode and Dual Role Power mode?
Hi ST GeniusesSo, for quite a while I have been trying to create an USB audio mic. Problem is: it is quite hard and not always a complete solution.And the X-CUBE-USB-AUDIO offers the complete solution, for audio and playback, even with feedback.The p...
I am studying USB PD. I am using the demo board B-G474E-DPOW1 and the project from the STM32CubeG4 examples. When I connect the USB-C cable to the charger, after the ATTACH event, I receive a list of possible profiles from Source. But when the cable ...
I am working with demo board B-G474E-DPOW1 and the project from the STM32CubeG4 Sink examples. I am trying to figure out how to connect an Audio Accessory. I have such an adapter. When I connect it to the usb-c, I expect to see an event with the conn...
