RPi makes ther own Mico controller
Seem that RPi have built there own micro controller. It is a dual core ARM M0 and they alreayd have a MicroPython port for it. The second core is designed for fast bit bang of IO pins so you can all software IO peripherals without bogging down the primary core. see https://www.hackster.io/news/hands...

Re: newbie issue with i2c
I have set both pins to input pullup before setting up the I2C has fixed this problem in the past.

Re: is creating a Region of interest possible?
it isn't that snapshot as that function, it is the fact that snap shot returns an array and this is how you can cut out of an array

Re: is creating a Region of interest possible?
I haven't used this board but to cut out a square ROI then something like this
Code: Select all
img = sensor.snapshot()[y:y+h, x:x+w]

Re: How to Build and Debug MicroPython Source Code with Eclipse
Not sure oif this will help but I use system workbench for all my STM32 projects. Which is also derived from eclipse and has all the needed toolchains and linker setup see https://www.st.com/en/development-tools/sw4stm32.html

Re: [ADAFRUIT_F405_EXPRESS] neopixel port advice
If you are confident in understanding how MP works you could implement the Neoplixel driver I made using a timer interupt to send the data. See here https://github.com/OutOfTheBots/STM32_NEOpixels_timer It has been tested on a STM32F407 there might be a few small tweeks for it to do eactly what you ...

Re: Can't get my NeoPixels to turn on
From the googling that I have done this seems to be the most common method for creating neopixle timings. basically work out how many NOPs are needed to get correct timings. Although it gets the job done it isn't very flexible to be able change the timings or running on different CPU freq MCUs. You...

omni directional dead reckoning
I have build an omni directional robot that can move with 3 DOF (x linear, y linear and w rotation). I do have another video (on my youtube channel) where I explain how I work out what speed to drive which motor to give me the desired x, y, w speeds. I have now worked out how to keep an accurate dea...

Low level stepper motor functionallity
There has been a few times where people have asked about functionality for using steppers in MicroPython. Atm there isn't any real way to do this because speed at which the ramp up and ramp down step pulses need to be generated at. I have made public my basic C code for being able to generate steppe...
