I think the sample rate is pretty irrelevant for us. Lowering it may lower power consumption.

Re: What is basic hardware requirements for micropython

there is no documentation of that chip whatsoever, it's dead in the water. some people will try to reverse engineer it, and if they like that, let them have fun, but i don't think this chip will see actual usage anytime soon. everyone using it right now is just in for the fun of figuring it out. if ...

profiling

I started writing a simple profiler: https://github.com/turbinenreiter/micropython-uprofile Before I did that, I looked into porting 'profile' from Cpython, which is a profiler written in python. However, it relies on 'compile', which isn't implemented yet. In the meantime, this little helper may be...

Re: data write speeds and broken SD cards

I nailed that down to the file.write(). It usually takes 5ms, but then suddenly 5000ms for one time. closing and reopening doesn't help. flushing also doesn't help. /edit: nopes. it's not the file.write(). happens even if i comment that out. //edit: adding a 1ms delay seems to fix that. still no ide...

Re: data write speeds and broken SD cards

Have any of you experienced 'hangs'? In my loop, I call gc.collect() on every iteration. Most of the time it runs at constant 200Hz, but sometimes it would hang for about 5s. If I only call gc.collect() on every n-th iteration, it happens more often. At the moment, I collect on every second iteratio...

Re: Expansion boards - pyshields

Ok, so I'm working on an IMU shield. First time designing a PCB. IMU shield BMP180 pressure/altitude sensor LSM9DS0 3-axis acceleromter/gyro/magnetometer (maybe: MMA6827 3-axis accelerometer for high g-loads) male pins for the 4 servo channels and pwr/gnd, so you can easily plug in servos Another sh...
