The hardware has: STM32F405RG microcontroller 168 MHz Cortex M4 CPU with hardware floating point 1024KiB flash ROM and 192KiB RAM Micro USB connector for power and serial communicationJan 26, 2021 · In this example we connect a PCF8574 expander to a Raspberry Pi Pico. Description. This 8-bit input/output (I/O) expander for the two-line bidirectional bus (I 2 C) is designed for 2.5-V to 6-V V CC operation. Hands-on MicroPython Examples for Edge Computing: Part 1. The new Digi XBee3™ line of embedded RF modules feature edge intelligence to help execute business rules and a whole lot more. By running simple Python-based scripts on Digi XBee3, you can save money, extend battery life, improve responsiveness and enhance system reliability.I´m the creator of the tensorflow-micropython-examples project. The purpose of this project is to make it easier to experiment with TinyML. At the moment we support ESP32 and RP2040. We have a STM32 port but there are some issues with it. On ESP32 we have hello-word, micro-speech and person-detection running. For RP2040 we have hello-world and micro-speech. STM32 did run hello-world but its ...The following are 13 code examples for showing how to use framebuf.FrameBuffer(). These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. You may check out the related API usage on the ...MicroPython is an efficient and lean implementation of the Python 3 programming language, which is optimized to run on microcontrollers.
