The microphone does increase amplitude with increased volume but it does not replicate a 500 Hz sine wave. Basically it's a volume detection. As of March 2025 loading get gsdk.a as shown above gives a compiler error. if anyone has a MG Sense and working microphone that can show show the actual sound waves reproducibility I would really like to know what you have done. The Speed Arduino Mic libraries all give distortion

Hi that didn’t work. I ended up dropping the DMA and just reading the ADC directly using P8 and P9 for enable and ADC input. Works beautifully. Not sure why the libraries are not working but 3 days of trying to follow the examples has cost enough time.RegardsBrian Russell022 378 6093On 6 Mar 2025, at 8:06 PM, giscus[bot] ***@***.***> wrote: Seeed Studio XIAO MG24 Sense built-in Sensor | Seeed Studio Wiki This article describes how to use the Microphone on the XIAO MG24 Sense. https://wiki.seeedstudio.com/xiao_mg24_sense_built_in_sensor/ —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you commented.Message ID: ***@***.***>
