Why a Raspberry Pi Pico?
Designing your own microcontroller instead of buying an existing one brings a number of advantages. According to Raspberry Pi itself, not one of the existing products available for this comes close to their price/performance ratio.
This Raspberry Pi Pico has also given Raspberry Pi the ability to add some innovative and powerful features of their own. These features are not available anywhere else.
A third reason is that the Raspberry Pi Pico has given Raspberry Pi the ability to create powerful software around the product. Surrounding this software stack is an extensive documentation set. The software and documentation meet the high standard of Raspberry Pi's core products (such as the Raspberry Pi 400, Pi 4 Model B and Pi 3 Model A+).
Who is this microcontroller for?
The Raspberry Pi Pico is suitable for both advanced and novice users. From controlling a display to controlling many different devices that you use every day. Automating everyday operations is made possible by this technology.
Beginner users
The Raspberry Pi Pico is programmable in the C and MicroPython languages and is customizable for a wide range of devices. In addition, the Pico is as easy to use as dragging and dropping files. This makes this microcontroller ideally suited for the novice user.
Advanced users
For advanced users, it is possible to take advantage of the Pico's extensive peripherals. The peripherals include the SPI, I²C, and eight programmable I/O (PIO)-state machines.
What makes the Raspberry Pi Pico unique?
What's unique about the Pico is that it was developed by Raspberry Pi itself. The RP2040 features a dual-core Arm Cortex-M0+ processor with 264 KB of internal RAM and support for up to 16 MB of off-chip Flash.
The Raspberry Pi Pico is unique for several reasons:
The product has the highest price/quality ratio in the microcontroller board market.
The Raspberry Pi Pico has been developed by Raspberry Pi itself.
The software stack surrounding this product is of high quality and comes paired with a comprehensive documentation set.
Multitasking and multiprocessing have become a very important topic in microcontroller-based systems, namely in complex commercial, domestic, and industrial automation applications. As the complexity of projects grows, more functionalities are demanded from the projects. Such projects require the use of multiple inter-related tasks running on the same system and sharing the available resources, such as the CPU, memory, and input-output ports. As a result of this, the importance of multitasking operations in microcontroller-based applications has grown steadily over the last few years. Many complex automation projects now make use of some form of a multitasking kernel.
This book is project-based and its main aim is to teach the basic features of multitasking using the Python 3 programming language on Raspberry Pi. Many fully tested projects are provided in the book using the multitasking modules of Python. Each project is described fully and in detail. Complete program listings are given for each project. Readers should be able to use the projects as they are, or modify them to suit their own needs.
The following Python multitasking modules have been described and used in the projects:
Fork
Thread
Threading
Subprocess
Multiprocessing
The book includes simple multitasking projects such as independently controlling multiple LEDs, to more complex multitasking projects such as on/off temperature control, traffic lights control, 2-digit, and 4-digit 7-segment LED event counter, reaction timer, stepper motor control, keypad based projects, car park controller, and many more. The fundamental multitasking concepts such as process synchronization, process communication, and memory sharing techniques have been described in projects concerning event flags, queues, semaphores, values, and so on.
Raspberry Pi cooling is a must. From the simplest passive heat sink, through elaborate fan blowers and even to an exotic water-cooled idea, many options are available.
Sequent Microsystems Smart Fan has the form factor of the Raspberry Pi HAT. Its own tinny 32-bit processor receives commands from Raspberry Pi through the I²C interface. A step-up power supply converts the 5 V provided by Raspberry Pi to 12 V, ensuring precise speed control. Using pulse width modulation, it powers the fan just enough to maintain a constant temperature of the Raspberry Pi processor.
The Smart Fan preserves all the GPIO pins, allowing any number of cards to be stacked on top of Raspberry Pi. If another add-on card has to dissipate power, a secondary Smart Fan can be added to the stack.
DIN-Rail Mounting
Together with multiple add-on cards, the Smart Fan can be installed on the DIN-Rail, for sturdy industrial applications.
Stack Level Jumper
Two Smart Fans can be installed on top of each Raspberry Pi. The assumption is that you have one more card in the stack which requires cooling. The bottom side of the Smart Fan has a jumper which needs to be installed on the second fan, in order for the Raspberry Pi to differentiate the two I²C addresses.
Features
40 x 40 x 10 mm fan with 6 CFM airflow
Step-up 12 V power supply for precise fan speed control
PWM Controller modulates the fan to keep constant Pi temperature
Draws less than 100 mA of power
Stackable to itself, 2 fans can be added to Raspberry Pi
Fully stackable allows adding other cards to Raspberry Pi
Uses only I²C interface, leaves full use of all GPIO pins
Super quiet and efficient
