Arduino IDE & A Arduino Bootloader
'Arduino IDE' is a special application program, enabling turning a powerful microntroller into an "Arduiono".
The Arduino IDE application provides an easy method for creating a "source code", compile a source-code, turning it into a "machine code" program for a specific model microcontroller IC chip, and uploading the compiled program into a microcontroller.
A special program, usually 512 bytes in size, referred to as a “Bootloader”, is preloaded into a specific model microcontroller, making it an "Arduino". As an 'Arduino', a microntroller is enabled to accept programs compiled by a version of the Arduino IDE application.
The bootloader is executed at power-up or reset of a microcontroller. The bootloader process checks for an incomming program at the serial/USB-port, using a specific protocol and speed. If no incomming program is detected, the bootloader is done and the microntroller begins to process a machine program if one exists in the flash-memory built into the microcontroller.
To write an 'Arduino bootloader' and upload it into a microcontroller, an 'In-Circuit Serial Programmer' (ISP) is required. An ISP device is connected to a specific set of pins of a microcontroller, to perform tranfering a program with bootloader into the built-in flash-memory in the microcontroller.
The ISP programming procedure, includes the writing of "fuses". Fuses are a special set of bits, used to control different functionality of a microcontroller.
Using An Arduino As A ISP
MKE Arduino Maker Space - Industrial - MKE USA - GREAT LAKES
Calling all Arduino enthusiasts, curious, hobbyists, tinkers, makers, builders, visionaries.....
I am a cofounder of MKE Maker Space, a newly emerging maker space, located in Industrial Milwaukee, WI. USA, near the Milwaukee port on Lake Michigan. Gary and myself, are looking to meet persons interested in learning microcontrollers and developing real world applications using computer and mechanical technologies by opening up our private industrial maker space to a makers. A space open for use, and to hang out, learn, create and share in creating and learning cool stuff... artists, to bakers, to chefs, to robot builders, to ship builders, to factory MEGA machine creations, to deep sea exploration and fishing 3D mapping and AI enabled devices and systems... we have a massive collective of knowledge and experiences to share and build my dream "ant hill" concept.
Professional Speaker Engagements
Cool, fun, exciting, educational, enlightenment, and personal knowlegebase enhancement....
Private tutoring in Milwaukee and Chicago, may be available. Professional speaker engagements available in Melbourne Australia, Chicago, Milwaukee, New York City, and other locations considered. Open to private groups, organizations, schools, and businesses.
Contact to continue the conversation.
