Programming 16-bit Microcontrollers in C: Learning to Fly the PIC24, A Volume in the Embedded Technology Series
* A Microchip insider tells all on the newest, most powerful PICs ever!
* FREE CD-ROM includes source code in C, the Microchip C30 compiler, and MPLAB SIM software
* Includes handy checklists to help readers perform the most common programming and debugging tasks
The new 16-bit PIC24 chip provides embedded programmers
with more speed, more memory, and more peripherals than ever before, creating the potential for more powerful cutting-edge PIC designs. This book teaches readers everything they need to know about these chips: how to program them, how to test them, and how to debug them, in order to take full advantage of the capabilities of the new PIC24 microcontroller architecture.
Author Lucio Di Jasio, a PIC expert at Microchip, offers unique insight into this revolutionary technology, guiding the reader step-by-step from 16-bit architecture basics, through even the most sophisticated programming scenarios. This book's common-sense, practical, hands-on approach begins simply and builds up to more challenging exercises, using proven C programming techniques. Experienced PIC users and newcomers to the field alike will benefit from the text's many thorough examples, which demonstrate how to nimbly side-step common obstacles, solve real-world design problems efficiently, and optimize code for all the new PIC24 features.
You will learn about:
* basic timing and I/O operations,
* multitasking using the PIC24 interrupts,
* all the new hardware peripherals
* how to control LCD displays,
* generating audio and video signals,
* accessing mass-storage media,
* how to share files on a mass-storage device with a PC,
* experimenting with the Explorer 16 demo board, debugging methods with MPLAB-SIM and ICD2 tools, and more!
1. Take offThe most dangerous phases of flight take off and landing. The parallel with learning a new development tool and possibly an entirely new language
We learn about the C30 compiler (student version) and we start developing code for the new 16-bit families of dsPIC and PIC24 microcontrollers.
- Use of MPLAB and the Simulator as a familiar environment,
- continuous parallels with assembly programming,
Proceed through:
1.1. Step by step installation of the compiler
1.2. Walk through some of the most basic steps of creating a new MPLAB project with the C30 language suite
1.3. the first #include, accessing the PICmicro resources in C
1.4. the first interrupt
1.5. Timing clock and
1.6. Hello (Embedded) World
1.7. Linking and running within the simulator
2. Touch and Go i.e. stay in the pattern and practice your landings. Debugging code with MLAB in a C30 project.
2.1. Watch for your Airspeed, that is: keep an eye on the clock (watch windows, stopwatch)
2.2. touch and goes, breakpoints and single stepping through C code (what the optimizer does to it)
2.3. use of the logic analyzer view
2.4. in the real cockpit: leaving the protected world of the simulator and starting to use the ICD2
2.5. tips for the perfect landing: print statements, bit toggling, asserts and other old tricks
3. Basic maneuvers basic C language constructs
3.1. allocating variables (and learn about RAM mapping)
3.2. loops (and learn about FLASH addressing )
3.3. conditions (and learn about register mappings)
3.4. functions (and learn about interrupts and subroutine calls)
4. Inside the engine compartment advanced, for assembly experts who don't trust compilers
4.1. What is my code translated to? A look at the assembly code generated by simple constructs
4.2. How efficient is it really? Comparing side by side an assembly routine to the compiler generated code.
4.3. the starter: C0 code
4.4. Leaning the mixture: Optimizing code
4.5. How is the compiler really allocating resources RAM and ROM
4.6. Owner maintenance: Mixing in some inline assembly
4.7. Buy certified or build your own: using canned libraries vs. your own libraries
5. Flying Cross Country, exploring more of the environment
the $100 burger; get some experience doing useful things like:
5.1. sending debugging data to the serial port to display on Hyperterminal (UART)
5.2. reading keystrokes from a PS2 keyboard (bit banging)
5.3. RTCC implementation (TIMER1)
5.4. reading a pot and using some Floating point math (ADC)
5.5. storing data in NVM (on chip/off chip) (EEPROM)
5.6. using a PWM as a D/A converter (PWMs)
5.7. reading a rotating gray encoder (Capture/Interrupts)
5.8. reading from a touch pad sensor (ADC)
5.9. Generating video output (Timers/Interrupts)
6. Complex endorsement (retractable gear and constant speed props)
6.1. Encryption and Decryption
6.2. Interfacing to a graphic LCD display
6.2.1. low level routines

6.4. Writing a basic interpreter
7. Final check ride: build a WAV player
7.1. deciphering the WAV file format
7.2. Mass storage
7.3. The user interface
7.4. Advanced filtering
7.5. Putting it all together
7.6. Connect it to the audio panel and fly away: Ethernet and USB connectivity
