Re: Battery and servo and USB
The Pyboard 1.1 has four sets of 3 pins on X1-X4 which are designed to connect to small hobby servos. They are powered from V+. If using USB, V+ will be just below 5V. If a LiPo is attached to Vbat, V+ is powered from the battery. The USB connection is protected by a diode, so you can connect both ...

Servo won't take negitive angles
I am using a PYB1.1 with firmware 1.12v (I know it isn't the latest but seem not to be able to update it) I am trying out the servo class and it seems to be working when I give positive angles between 0 and 90 but it won't let me give it negative angles. see below for debug MicroPython v1.12-557-g3a...

Battery and servo and USB
I have a PYBv1.1 and I am wondering about driving HV servos (7v to 8v) directly off the board. I notice that the board has 4 sets of pins setup for driving servos (X1 to X4) with GND and V+ next to them to directly plug servos straight in. I do also notice that there is a Vbat next to them. Here's m...

Re: RPi makes ther own Mico controller
Hacker News has a good discussion ; it's where I first saw links to the (beautiful!) datasheet . Chapter 3 covers the PIO in-depth. It's also worth looking at the PR; there are some useful PIO examples there (including controlling WS2812B's). The first thing that come to my mind when I read about t...

Re: RPi makes ther own Mico controller
The MicroPython port for the RP2040 is awaiting your review... ;) Ha Ha Ha. I am certainly finding it hard to resist the urge to buy 1 and have a play with it, as it looks super interesting and RPi is usually very well supported fro beginners. My other life (the real one) has been busy with running...

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
