An Open-Source Platform for Learning Embedded Systems Based on Algorithm Visualizations and Digital Signal Controllers
electronics Article DSCBlocks: An Open-Source Platform for Learning Embedded Systems Based on Algorithm Visualizations and Digital Signal Controllers Jonathan Álvarez Ariza Department of Electronics Technology, Engineering Faculty, Corporación Universitaria Minuto de Dios (UNIMINUTO), 111021 Bogotá, Colombia; [email protected]; Tel.: +57-310-557-9255 Received: 17 January 2019; Accepted: 29 January 2019; Published: 18 February 2019 Abstract: DSCBlocks is an open-source platform in hardware and software developed in JavaFX, which is focused on learning embedded systems through Digital Signal Controllers (DSCs). These devices are employed in industrial and educational sectors due to their robustness, number of peripherals, processing speed, scalability and versatility. The platform uses graphical blocks designed in Google’s tool Blockly that can be used to build different Algorithm Visualizations (AVs). Afterwards, the algorithms are converted in real-time to C language, according to the specifications of the compiler for the DSCs (XC16) and they can be downloaded in one of the two models of development board for the dsPIC 33FJ128GP804 and dsPIC 33FJ128MC802. The main aim of the platform is to provide a flexible environment, drawing on the educational advantages of the AVs with different aspects concerning the embedded systems, such as declaration of variables and functions, configuration of ports and peripherals, handling of Real-Time Operating System (RTOS), interrupts, among others, that are employed in several fields such as robotics, control, instrumentation, etc. In addition, some experiments that were designed in the platform are presented in the manuscript. The educational methodology and the assessment provided by the students (n = 30) suggest that the platform is suitable and reliable to learn concepts relating to embedded systems. -

Microchip Miwi P2P Wireless Protocol
AN1204 Microchip MiWi™ P2P Wireless Protocol This application note assumes that readers know C Author: Yifeng Yang programming. However, it also recommends that Microchip Technology Inc. readers review the IEEE 802.15.4 specification and Microchip MiMAC/MiApp interfaces before starting this application note or working with the MiWi P2P wireless INTRODUCTION protocol. The demand is growing for more and more applications to move to wireless communication. Protocol Overview The benefits are reduced costs and ease The MiWi P2P protocol modifies the IEEE 802.15.4 implementation. Wireless communication does not specification’s Media Access Control (MAC) layer by require cabling and other hardware, and the associated adding commands that simplify the handshaking installation costs. It also can be implemented in locations process. It simplifies link disconnection and channel where installing cable is difficult. hopping by providing supplementary MAC commands. Since the IEEE released the Wireless Personal Area However, application-specific decisions, such as when Network (WPAN) specification (IEEE 802.15.4™) in to perform an energy detect scan or when to jump 2003, it has become the real industry standard for low- channels, are not defined in the protocol. These issues rate WPANs (LR-WPAN). The specification applies to are left to the application developer. low data rate applications with low-power and low-cost requirements. Protocol Features Microchip MiWi™ P2P Wireless Protocol is one of the wireless protocols that are supported in MiWi The MiWi P2P Wireless Protocol has the following Development Environment (DE). It is a variation of features: IEEE 802.15.4, using Microchip’s IEEE 802.15.4 • Operates on Microchip PIC18, PIC24, dsPIC33 compliant and other proprietary RF transceivers, which and PIC32 platforms are controlled by Microchip 8, 16 or 32-bit • Supports Microchip C18, C30 and C32 compilers microcontroller with a Serial Peripheral Interface (SPI).
