Development

  • 1.Developing program to Microduino-core, players need to use Microduino-USBTTL module.
  • 2.The tutorial of setting up the development environment and installing the driver is as following:
  • Program Microduino BootLoader.
    • If you get a Microduin-Core empty board, you need to use Arduino UNO or the existing Microduino to program bootloader for another Microduino empty board. YOu can refer to the tutorial Do you know how to use Arduino UNO to program bootloader to Microduino-Core？.
    • Each version of Microduino-Core uses different bootloader, and the initial bootloader is the bootloader that the optiboot aims at ATmegaX8 set, and it takes 512 bytes flash space.

Application

FAQ

  • Q:How can I judge the voltage of my Core is 3.3V or 5V？
    • A:By the resistor. If the R1 is soldered, it is 3.3V, and if R2 is soldered, it is 5V.
  • Q:Can I supply power to the Core+ of 16M color frequency with 3.3V？
    • A:It is not recommended. If the voltage is too low, it will be easy to be unstable.
  • Q:Can I use 5V voltage to supply power to the core of 8M clock frequency？
    • A:You can.

History

  • On December 16, 2012, the Arduino IDE support service pack for Microduino Coreis published. Refer to Install Arduino IDE Microduino hardware support package for the detail.
  • On November 18, 2012, the first released version was determined. Cut down some functions, maintain the minimum system of lean, reduce the cost and adopt beautiful manual wiring appearance.
