Re: i2s compatibility

I an an enginner and luthier and I need to develop for that for a micropython aided tuning tool ;) So I have plenty of sensor (flowmeter, barometric sensor, IR sensor, mostly in I2C, and also a I2S microphone. This will be mixed with FFT / intermodulations pitch measuring algoruthm and a TFT screen....

Re: i2s compatibility

Just a technical question, how can I use a Pull request on github to update my micropython local folder ? I suppose there is a special git command, or should I download a zip copy of this micropython branch ?

Re: FFT with micropython

Hi Peter, Regarding my case, do you have any idea to perform a polyphonic pitch tracking with micropython ? I wonder if the FFT is really the optimal way to compute this regarding accuracy (0.1 cents). Regarding this work, https://miracle.otago.ac.nz/tartini/papers/A_Smarter_Way_to_Find_Pitch.pdf I ...

FFT with micropython

Hi, I do some research in musical acoustics and I would needs to perfoms FFT for musical multiple tones tuning appllication and I would like to use micropython. I wants to to implement a FFT made on ADC signal obtain by an electret microphone and I need to find the fundamental frequencies of multipl...

Re: Adding libraries to the binary image

Question : in the modules directory, do I need to put all the files for the micropython-lin I wants to freezes ?

For exemple I wants to freeze the upip in my pyboardv11 firmware, should I pout all the upip forlder in the submodules folder I create in ports/stm32 folder ?

Re: New STM32H743VIT6 dev boards

Do you wants I try to compile to see if I get any errors ?

For pictures, you need to upload a picture over the internet and to put the link here ... (imageshare, drive, ftp , ..;)

Thanks a lot !
