mbed @ Elektor Live! 2010
- 1. Simon Ford Elektor Live! mbed Workshop 1
- 2. Outline • Introduction • Hello World! – Get you in control of the hardware... • Walkthrough Example! – A feel for how things work... • Workshop! – Time to experiment... 2
- 3. Before we start! • Check that... – you have an mbed – you have a laptop – you have a working internet connection 3
- 4. • Microcontrollers are getting cheap – 32-bit ARM Cortex-M3 Microcontrollers @ $1! • Microcontrollers are getting powerful – Lots of processing, memory, I/O in one package • Microcontrollers are getting interactive – Internet connectivity, new sensors and actuators • Lots of new opportunities for microcontrollers! What’s happening to Microcontrollers?
- 5. Sydney Powerhouse Museum – We’re now at the same tipping point with microcontrollers
- 6. – Ideas come from anywhere, need prototyping to test them Microcontrollers are a great solution, looking for problems! Eureka! If I could automate feeding my pigs, I’d be able to sleep in! Eureka! If I could automate feeding my pigs, I’d be able to sleep in! Eureka! I could use my electronics skills to help... pig feeding! Eureka! I could use my electronics skills to help... pig feeding!
- 7. Rapid Prototyping • Rapid Prototyping helps industries invent products • We want prototyping with electronics to keep pace! – Let you prototype control, communication, interaction too 3D Moulding 3D Printing 2D/3D Design Web Frameworks
- 8. So we built mbed!
- 9. • Fastest way to start with an ARM microcontroller – Plug ‘n’ Play Hardware, Online Compiler – Make picking up and working with a microcontroller fast! What is mbed?
- 10. • Designed for rapid prototyping by a wide audience – Prototyping form-factor, High-level Library APIs – Help you invent new products with microcontrollers! What is mbed?
- 11. • Integrated mbed.org developer site and community – Online resources, tools for support and collaboration – Help to build an active, supportive developer community! What is mbed?
- 12. mbed NXP LPC1768 Hardware 12
- 13. What is the LPC1768 Microcontroller? 13 NXP LPC1768 ARM Cortex-M3 100MHz 512KB FLASH 64KB RAM ARM Cortex-M3 32-bit MCU Core Thumb-2 Instruction Set 3-stage, Modified Harvard NVIC (Nested Interrupts)
- 15. Hello World! (1) 1. Plug it in 2. ... 3. Download and run your first “Hello World!” binary! 15
- 16. Hello World! (2) 1. Click the compiler link 2. ... 3. Compile and run your first “Hello World!” binary! 16
- 17. Hello World! (3) 1. Try modifying the code a bit Flash a different LED, change the speed, make a new pattern 1. ... 2. Compile and run your own “Hello World!” binary! 17
- 18. A feel for how things work... Walkthrough Example! 18
- 19. Walkthrough Example • Make a simple datalogger – AnalogIn for reading analog values – LocalFileSystem for storing data to files 19
- 21. Our experience of workshops • Everyone learns differently, and at a varying pace • Everyone has different levels and areas of experience 21
- 22. Our strategy for workshops • Make equipment and resources available • Let you explore what you want, at your own pace • Use the mbed Handbook and Cookbook for guidance • Provide support to you as you need it 22
- 23. Components to experiment with! 23
- 24. Components to experiment with! 24
- 25. Breakout Boards! – Cool Components Breakout, Starboard Orange Breakout 25
- 26. m3pi Robots! – Line sensors for linefollowers, Bluetooth for remote control 26
- 27. Use the Handbook and Cookbook...
- 28. Step-by-step introductory project • For absolute beginners • An extract from: ARM microcontrollers, Part 1 35 projects for beginners By Bert Van Dam • Simple AnalogIn Experiments 28
- 29. Workshop Rules • Experiment with whatever components you want – Some things are more complex than others; start simple • Be considerate of others – Please return all the components as you finish with them • Don’t be afraid to ask for help or guidance – We’ve sat everyone next to an assistant • Go for it! 29
- 30. NXP mbed Design Challenge Develop a product prototype, reusable library or reference design, share it on http://mbed.org, and help others build their prototypes even faster!
