A g-sensor Based Alarm System for Multiple Tilt Sensor Applications Using VHDL and FPGAs

2024

A g-sensor based alarm system, available for use in many tilt sensor applications, was programmed and put in use in this work. The DE10-Lite FPGA was used, with its digital accelerometer sensor module ADXL345. The tilt sensor is programmed to present in seven segment display of the FPGA board, angle values from 0 to 90 degrees, using minus sign when the slope is to the right and the positive one when it tilts to the left, thus informing us about the sensor's tilt direction. Simultaneously the FPGA's right or left LEDs light up according to system tilt. It also uses key button for freezing its operation, hence presenting the latest angle value. The program controlling the sensor gives the ability of entering a critical angle value, depending on the application. As soon as this value is exceeded buzzer is activated, thus giving our system an alarm behavior.

Implementasi Fpga Sebagai Sistem Pemonitoran Pada Pengontrol Kecepatan Motor DC

2015

Abstrak—FPGA menawarkan keuntungan proses aritmatika dan logika lebih cepat daripada mikrokontroler. Implementasi FPGA sebagai sistem pemonitoran diperlukan untuk memudahkan pengguna dalam menentukan nilai parameter PID khususnya pada sistem kontrol berbasis FPGA. Dalam penelitian ini, sistem pemonitoran diwujudkan dalam implementasi FPGA Xilinx Spartan 3E Nexys2 kit board menggunakan VHDL. Desain dan sintesis dari sistem pemonitoran digunakan software ISE Design Suite 14.6. Masukan sistem berupa pin PS/2 Keyboard, pin PWM dan pin Rotary sedangkan keluaran sistem berupa tampilan pemonitoran dari sinyal PWM dan sinyal Rotary serta nilai parameter PID pada VGA monitor. Masukan sinyal PWM dan sinyal Rotary serta nilai parameter PID dijadikan ke dalam bentuk data bitmap. Data-data bitmap diserempakan dengan scan line VGA monitor sebagai tampilan pixel dari sinyal PWM dan sinyal Rotary serta nilai parameter PID. Warna tampilan pixel pemonitoran pada VGA monitor hanya terdiri satu warna s...
