Re: Phase Mesurement with Pyboard up to 100 kHz

I started working again on the project after long break. As i found out i also have to mesure much lower frequencies, down to tens of mHz. Yes mHz not MHz! As i learned it's very common in geology to use such low frequencies. At first i thought no Problem, just make longer Frames. But i noticed quic...

Re: Phase Mesurement with Pyboard up to 100 kHz

Thanks for your nice work Peter. You are right the noise will disturb my measurement, my idea was to measure several times and calculate the median. I only want to use it for frequencies witch are to high for the ADC. Yesterday i tested your code from the link. It works fine and the implementation i...

Re: Phase Mesurement with Pyboard up to 100 kHz

Thanks, this Link is very Interesting. But i had another Idea with comparing just the time when the signals reach 0. I was thinking to use the build in comparators. now i read the documentation again and found out the microcontroller of the pyboard has no. My idea is now to use the timer with extern...

Phase Mesurement with Pyboard up to 100 kHz

Hello i want to build an impedance spectroscopy device. The main idea is to measure the impedance of a test object to gain information about the materials. I would like to use it for solid investigation. For this i have to measure phase and amplitude of some sine waves with known frequencies between...

Re: MicroPython with VisualStudio Code

Hello from San Luis Argentina. Nice Work. I run the script for the stubbs on a Lopy 1.0 with pycom Firmware and it works fine. The use in VisualStudio i have not tested yet. I prefer to use Atom is there a possibility to use the stubs with the Jedi Plugin in Atom?
