The new STM32F405 Feather that Adafruit designed runs CircuitPython at a blistering 168MHz – our fastest CircuitPython board ever! We’ve tried it out with an AirLift Breakout and it’s incredibly quick. First, make sure you are running the latest version of Adafruit CircuitPython (https://adafru. Next you'll need to install the Adafruit CircuitPython BME680 library on your CircuitPython board. io with the Adafruit people about their fork and the plans they have for it. I don't think the CurcuitPython API is any simpler than the MicroPython API. CircuitPython lets you draw graphics, play wave files and print out text in any fonts - all in Python! There's tons of sensor support as well. You need this for anything Internet; adafruit_pyportal - This is our friendly wrapper library that does a lot of our projects, displays graphics and text, fetches data from the internet. On each side of the Hallowing are JST-PH plugs for connecting external devices. Adafruit CircuitPython features unified Python core APIs and a growing list of Adafruit libraries and drivers of that work with it. For other Adafruit products (Baro BMP280, Gyro L3GD20H), the tutorial shows clearly the necessary code to use SPI, but for the ADXL345, it seems to show only I2C code. I2C Protocol. Coming Soon - Adafruit Feather STM32F405 Express. Assembly Putting together the backpack onto an LCD is a quick process, and should take only a few minutes with a soldering iron. It is typically faster than I2C because a separate pin is used to control the active slave rather than a transitted address. This library provides a variety of data descriptor class for Adafruit CircuitPython that makes it really simple to write a device drivers for a I2C and SPI register based devices. The CircuitPython NeoPixel Library has been updated to include support for driving NeoPixels via an available SPI port. WiringOP, a modification of WiringPi, is for GPIO usage only, it doesn't work well for various I2C or SPI devices. So it's great once you've finished up a prototype on a Metro M0 or Feather M0, and want to make the project much smaller. NEW PRODUCT – Adafruit PyRuler – Engineer Reference Ruler with CircuitPython The first time you soldered up a surface mount component you may have been surprised “these are really…. This is a very good introduction and beginning. A Feather nRF52840 Express will run CircuitPython and an older Wemos Lolin ESP32 will act as the co-processor. The new STM32F405 Feather that Adafruit designed runs CircuitPython at a blistering 168MHz – our fastest CircuitPython board ever! We’ve tried it out with an AirLift Breakout and it’s incredibly quick. Adafruit METRO M0 Express - designed for CircuitPython - ATSAMD21G18 Metro is Adafruits series of microcontroller boards for use with the Arduino IDE. This amazing little device puts a NeoPixel + an Audio board + a USB port along with a 120 MHz Cortex M4 Core and a mic amplifier and you can program it with CircuitPython. Unlike the original Feather M0 Basic, it added a NeoPixel status LED and external 2MB SPI Flash for storing CircuitPython code. Adafruit CircuitPython BusDevice. First, make sure you are running the latest version of Adafruit CircuitPython (https://adafru. The Adafruit Feather M0 Express was one of the first development boards designed for CircuitPython by Adafruit. Adafruit Industries, Unique & fun DIY electronics and kits Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) ID: 2633 - Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project?. I am using SPI interface for communicating with IC. The most exciting part of the ItsyBitsy M0 is that while you can use it with the Arduino IDE, we are shipping it with CircuitPython on board. CircuitPython support, the extra 8 MB of SPI Flash is great for sound effects projects where you want to play up to 3 minutes of WAV files. The bundle includes the Adafruit_CircuitPython_BLE library. Adafruit Industries, Unique & fun DIY electronics and kits Circuit Playground Express ID: 3333 - Circuit Playground Express is the next step towards a perfect introduction to electronics and programming.
