Posted on July 16, 2018 at 04:10What is the ADC resolution of the Wolfson CODEC used ? I've seen 24bits, 16bits, 12bits ?? Is the 24bits differential Audio ? and the 12bits single ended Audio ? How do I access the 3 12bit ADCs on the STM chip from t...
Posted on October 14, 2017 at 03:33With STM32CubeF7 V1.8.0, there is no audio output from the wm8994 audio chip via the 3.5 mm blue audio output jack on the STM32F769I-Discovery board when parameter OUTPUT_DEVICE_HEADPHONE (or alias OUTPUT_DEVICE_HEA...
Posted on February 01, 2018 at 12:55 Hi everyone: I am trying to build an audio effects processor on the STM32F7Discovery board. I am relatively new to this matter as I have never used a microcontroller before, and I am having a bit of trouble tr...
Posted on December 14, 2017 at 03:38Hi everybody!I have a project which uses STM32F769 Discover board.In my project, I want to record voice, save that voice data and then play that data after I press user button.I also referred to demonstration exam...
Posted on November 25, 2017 at 17:09Hello everyone,a while ago I started looking into the STM32746 to test some DSP audio effects, but I don't have much experience with STM32 MCUs. I mainly had issues with sdram access (see https://community.st.com/...
Posted on October 16, 2017 at 14:38Hi.I'm trying to output 24khz mono pcm data over SAI to wm8994 codec. 16khz mono seems to work OK, but 24 is not supported by ST by default. I've made some changes for the support to codec and sai init. Now I wonde...
Posted on August 21, 2017 at 21:56I browsed the forum it looks like people already asked this question but no clear answer has been posted.Like others, I am able to run the USB FS Audio example on Disco board (746) but it gets into 'Incomplete ISO I...
Posted on July 11, 2017 at 17:23Hi Communities,I am using STM32F745VGTX Chip for my audio playing wave file application. My problem is that playing wave file takes too much processor power, therefore I want to use DMA instead. Is there any DMA mode,...
