A collision avoidance system, also known as a pre-crash system, forward collision warning system, or collision mitigation system, is a sophisticated driver-assistance system that aims to avoid or mitigate the severity of a collision. For this research, collision avoidance system will be fabricating to show that this system can detect avoidance range before apply the braking action to prevent collision. The ultrasonic sensor will be used in this system to detect the avoidance range. In this collision avoidance system, there will be uses of Field Programmable Gate Array (FPGA) and Complex Programmable Logic Device (CPLD). This research will observe how to implement FPGA and CPLD in the collision avoidance system using VHSIC Hardware Description Language (VHDL). The VHDL will be done in Quartus II 15.0 Software. In this research, Terasic DE-10 Standard board has been used. It contains FPGA microcontroller model Cyclone V SoC 5CSXFC6D6F31C6N. Max II board is used because it contains CPLD microcontroller model EPM240T100C5.

Los robots colaborativos son de interés en variadas áreas de control, especialmente en la manipulación, desarrollo y precisión de tareas programadas; parte de su funcionalidad radica, entonces, en la plataforma de comunicación entre ellos. En este artículo de investigación se presenta el desarrollo de una plataforma para la comunicación entre robots colaborativos empleando dispositivos lógicos programables CPLD (Complex Programmable Logic Device), sensores ultrasónicos y sensores infrarrojos con la finalidad de que realicen múltiples tareas. Según la forma en que sean programadas, estas plataformas robóticas pueden apoyarlas empresas a enfrentar dificultades tales como los altos costos derivados de otras plataformas robóticas convencionales; asimismo, pueden orientarse a facilitar tareas cotidianas —como la transportación de objetos o el apoyo en labores domésticas—que se pueden automatizar de manera eficaz.

<span>In the developed system ARM9 is a master and Two ARM7s are slaves. The peripherals are being controlled by two ARM7 boards. The Peripherals are connected to the ARM7 through Complex Programmable Logic Device (CPLD). The CPLD is in turn connected to the ARM7 using Serial Peripheral Interface (SPI). The ARM7 boards collect the information from the peripherals and send it to the ARM9 board. The communication between ARM7 and ARM9 is via UART (Universal Asynchronous Receiver Transmitter) over CAN (Controller Area Network). The ARM9 board has got the software intelligence. The ARM9 behaves as a master and two ARM7 boards behave as slaves. Being master ARM9 passes tokens to ARM7 which in turn returns (Acknowledges) the token. The ARM9 is further connected to Proxy via Ethernet. The proxy is further connected to the service platform (server) via Ethernet. So subsequently any decisions at any stage can be changed at server level. Further these commands can be passed on to ARM9 which in turn controls the peripherals through ARM7. (a) The system which we have developed consists of ARM9 as a master, Two ARM7 as Slaves. The communication between ARM9-ARM7 is via UART over a CAN, <br /> (b) Each ARM7 further communicates serially (RS232) with the two 8051 Microcontroller nodes, (c)Thus a networked Embedded System is developed wherein the serial data is brought over Ethernet. The ARM7 board, which is directly linked with the peripherals, can be modified of its functionality as and when required. The functionality of ARM7 can be modified by upgrading its firmware. To upgrade the firmware same communication link has been used. ARM7 receives the new firmware via same ARM9-ARM7 communication link. The Flash Write operation is performed using the source code to write the new firmware. Bootloader application for the ARM7 has been developed. The signature has been incorporated to assure authenticity of the new Firmware. Intel Hex File Format is used to parse the hex file.</span>

Makalah ini menjelaskan tentang proses pembelajaran mata kuliah perancangan chip digital berbasis proyek yang menerapkan Finite State machine (FSM) sebagai metode untuk merancang pengendali motor stepper menggunakan VHDL. Motor stepper yang digunakan dalam studi kasus ini adalah motor stepper unipolar. Dimana motor stepper tersebut dikendalikan dengan 2 mode, yaitu half-step dan full-step. Pengendalian pada mode full step terdiri dari 2 cara yaitu dengan kendali 1 phase ON dan 2 phase ON. Pengendali motor stepper diimplementasikan pada chip Complex Programmable Logic Device (CPLD) dengan seri EPM3032ALC44-4. Dari hasil simulasi waktu yang dibutuhkan dari input sampai ke output membutuhkan waktu 3 ns. Kata kunci : Pengendali, Motor Stepper, FSM, VHDL

This paper introduces the hardware and programming involved in collecting the image of the digital code wheel by microprocessor STM32 directly driving camera chip OV7670 and the transmission of collected image. This design simplifies the hardware structure to the greatest extent and minimizes cost. Our design has three advantages. Fist, direct driving saves the intermediary register chip, simplifies the circuit and also reduces the amount of elements used. Second, by using the CMOS digital image sensor with windowing function—OV7670 to capture the image of code wheel we simplify the hardware structure and reduces the cost because of the D/A conversion circuit and complex programmable logic device contained in OV7670. Third, we successively solve the problem of the small capacity (20k) of STM32F103C8T6 chip’s SRAM by cutting out 24080 images from 640480. So time spent on data transmission and processing can be shortened.
