Re: ESP32 Camera (ESP32 Cam) Library
Thanks for the firmware and examples. I noticed that in the webcam example https://github.com/tsaarni/esp32-micropython-webcam/blob/master/webcam.py that camera has a capture method that stores the camera sensor data into a buf. Would anyone know of any way to convert this data to an image file (say...

Re: ESP8266: instead of main.py start from REPL an script
I recently got the ESP8266 and had a play around. I made a "note to self" of my workflow. Check it out: https://github.com/KipCrossing/ESP2866-MicroPython
I put my code in a different file just in case my main.py file got corrupted. It seems difficult to remove corrupted files.

Re: PyBoard Timer Question
Thanks for your input! :D how do you ensure that you start read_timed at a known point in the PWM I guess I could use Timer.OC_TOGGLE and half the period to get the same frequency. Then set the counters to 0 each loop (Thanks for that tip btw) I would really like to have a practical example (code) o...

Re: PyBoard Timer Question
I thought of that and it will probably work lower frequencies. With higher frequencies around 20 kHz the precision of measuring the phase will be a lot worse. The read_timed_multi() Method maxes out at around 200 kHz meaning there would be only 10 samples per wavelength. Therefore when observing the...

PyBoard Timer Question
Hi all, I need some advice when it comes to using timers. I want to read with an ADC and at every n’th (say 5) sample toggle a different GPIO. This is to produce a square wave and get the resulting wave via ADC after induction between 2 coils. See example https://github.com/KipCrossing/OpenEM/blob/m...

ADC specs
Hey all, Does anyone have any idea of the ADC specs of the D-series PyBoards? There are a few things that I'd like to know before I buy, including: Max sample rate Resolution And whether it incused an ADC.read_timed_multi() method (and what the sample rate for this would be) I couldn't find anything...

Re: Push files from local to PyBoard
Great, that's just what I needed! If anyone is interested, I did the following to get what I wanted: 1. Install rshell sudo pip3 install rshell 2. Create a custom command by making a upyrun file in /usr/bin/ sudo nano /usr/bin/upyrun 3. Add the following commands to the upyrun file: git add . rshell...

Push files from local to PyBoard
Hi, I'm just wondering if there are any methods/projects that would allow me to send files and commands to the PyBoard. I would like to work in a directory on my computer (so I can use git) but not manually copy and paste the files to the pyboard every time. I imagine one command that: git add . Pus...
