Re: STM32L4 Core

Hi gato_,

Could you share how you turned your sketch into an eclipse project with openocd debugging? I'm using this core too.

regards,
Arthur

Re: aerospace engineer

Ooh that optical flow thing is interesting - I was working on that a lot years ago with OpenCV on Linux. I actually wrote the "Median Flow" implementation there in C++, but it's actually a massively parallel computation that suits GPUs better (or FPGAs) than regular processors. However those sensors...

Re: aerospace engineer

Yes, Kalman filters would improve it, but the cumulative error would still be there. Unfortunately accelerometers and gyroscopes cannot be made more accurate because of regulations rather than technical limits,otherwise they will become subject to ITAR regulations (anything better than 130 ug or 130...

Re: aerospace engineer

I made my first altimeter with an Attiny85 with 8kb of flash and 1kb of sram - I had to do some hacks to make the sketch fit, and also work around the lack of floating point in the hardware. I'm quite used to making code as efficient as possible... so I've barely scratched the surface of what my STM...

Re: aerospace engineer

A simple MCU to talk to BMP280 doesn't need to be powerful at all - just I2C, avrs can do it quite easily. But I'm now adding lots of things - a high resolution LCD, an MPU9250 sensor, bluetooth, a GPS antenna and getting it to calculate heading, ground track, glide slope and navigation among other ...

aerospace engineer

Hello! I'm Arthur, based in the UK. I'm new to STM32, been programming AVR through Arduino for the past 5 years or so but I've started outgrowing the limited RAM, flash and power of the AVRs. I'm an aerospace engineer, specialised mostly in aerodynamics and structures, but I've had electronics as a ...
