Micro speech example based on Edge Impulse

1

Hi, mocleiri. After I successfully completed the image classification based on edge impulse and tensorflow-micropython-examples, I began to try the audio classification based on edge impulse. At the beginning, my...

Improve documentation around SPIRAM_USE_MALLOC versus SPIRAM_USE_MMAP on esp32.

1

For implementing person detection we got a change made in upstream micropython so that building the firmware using the **SPIRAM_USE_MALLOC=y** sdk config enables a sharing PSRAM mode where 1/2 of...

See if we can use esp-dsp to accelerate esp32 math ops

18

I found out that esp32-s3 will have improved hardware support for some dsp functions. But that espressif also have an esp-dsp module that also provides improved/optimized code for regular esp32...

https://github.com/micropython/micropython/pull/8219 was merged and the micropython-camera-driver upstream added a new option where by you can configure the location of the camera framebuffer to be in regular RAM or PSRAM. ```...
