Microduino- CoreSTM32

Microduino-CoreSTM32 is one of the core modules of Microduino, adopting ARM development board of STM32F103CBT6 chip. Microduino-CoreSTM32 is a open-source software, compatible with Maple Mini, and it can be used together with Microduino extension modules and other electronic components, modules, and sensors to make many funny interactive works.

Features

  • Small, cheap, stackable, and open;
  • Open source hardware circuit design and programming development environment similar to Arduino.
  • Microduino-CoreSTM32 can be downloaded with bootloader through Microduino-USBTTL;
  • With an uniform Microduino interface standard and rich peripheral modules, it can be easily connected with other Microduino modules and sensors.
  • 2.54mm-spacing female connector interface,which makes it easy to integrate to the pegboard.

Development

Set up the Microduino-CoreSTM32 development environment(1)

  • Use the Maple IDE development environment: Microduino use the similar development environment with the Arduino IDE, so you can use the Maple IDE, Flash or Processing and so on. Combining with other Microduino modules, you can make many interesting interactive works..
  • Configure the Maple IDE, please refer to Microduino-CoreSTM32 Maple Drive Install
  • TO download programs to Microduino-CoreSTM32, just use the USB interface of Microduino-CoreSTM32, without Microduino-USBTTL, which is only used when programming bootLoader. There is bootloader, by default, so you don't have to program it.

Program for Microduino-CoreSTM32

  • Make sure installed the Microduino-CoreSTM32 derive
  • Prepared hardware：Microduino-CoreSTM32, USB cable
  • Prepared software：Maple IDE

Set Microduino-CoreSTM32 Development Environment（2）

  • Use Keil uVision development environment: To develop Microduino-CoreSTM3, software keil can also be used. This environment can not only use C language, but also assembly language to program. And it has accessible integration environment, and powerful software simulation debugging tolls. Keil provides a complete development plan, including C compiler, macroassembler, exoskeleton, library manager, and a powerful simulation debugger, which are combined together by an integration development environment（μVision.
  • To configure Keil uVision development environment, please refer to Configuration of Microduino-CoreSTM32 Keil development environment
  • To download programs to Microduino-CoreSTM32, you can directly use the USB interface of Microduino-CoreSTM32. And to execute online breakpoint debugging, another module Microduino-CoreSTMDEBUGE is needed, namely stlink.And you can stack the two modules and connect them through the USB interface of Microduino-CoreSTMDEBUGE to the computer to download programs.

Program Microduino-CoreSTM32（2）

  • Please make sure that you have installed STLINK driver.
  • Required hardware: Microduino-CoreSTM32、Microduino-CoreSTMDEBUGE, and a USB cable.
  • Requires software: Keil uVision5
