Re: Using the Portenta's IMU with Micropython code

I was thinking of getting the adafruit lsm9ds1 https://learn.adafruit.com/adafruit-lsm9ds1-accelerometer-plus-gyro-plus-magnetometer-9-dof-breakout as it should work with the same code as the accelerometer examples for the Nano33BleSense. Anyone know if this accelerometer works with the PortentaH7? ...

Re: Portenta Vision Shield micro-python on the M4 core?

From OpenMV's point of view I agree the M7 core is probably the best place for your firmware as it is faster and almost has as much memory as the Nan0o 33 BLE, but from an Arduino users point of view having options is always better than no options. I believe the M7 core is faster but my results sugg...

Portenta Vision Shield micro-python on the M4 core?

Most of my Portenta programs are completely interchangeable between the M7 and M4 core especially since Arduino has improved the RPC communication with the M4 println. Wondering if the OpenMv code could be placed on the M4 core. I have another thread talking about RPC communication between python an...

Quick question, since my installation may have some issues, does your portenta with camera work when disconnected from the IDE. Say just powered with a usb battery? Mine doesn't, just curious if yours does.
