The goal is to keep the main Flight-Controller loop reads accelerometer, and gyro, and move the reset of the I/O to read threads. Links mentioned in video: - Adaf In this example we'll look at SPI master mode where a MicroPython board acts as the master to control the SPI communication with other devices. These interfaces aren't enabled by default, and need some extra configuration before you can use them. Welcome to pySerial’s documentation¶. Getting Started. There are many projects with an e-ink display and the Raspberry Pi, but I first tried with an ESP32 and MicroPython. Are You a New User? If so, here's the basic stuff you need to read and know: The Official Pyboard Quick-Start guide and some community added details Bridges - Pretend your PC a Raspberry Pi or an ESP32 to connect I2C/SPI/GPIO/UART peripherals An Introduction to MicroPython. This module encapsulates the access for the serial port. That solution didn't work (something was not working with the reset voltage - too much signal noise). One is  8 Apr 2018 Below is a quick reference guide to Wemos D1 pin mapping for GPIO, I2C and SPI when working from MicroPython. Setup. Features¶. write [. 4) and implements a small subset of the Python standard library so even seasoned Python veterans will find MicroPython familiar and fun to use. IoT-ALE: Reading Sensor Data with I2C Introduction to SPI and SPIdev. Ayan Pahwa - March 25, 2017. After some years of using my SSD1306 library driver on Raspberry Pi, I needed to get it working with the new more and more popular 1. I am using python with the spidev library to try and communicate with the xbee. micropython spidev
