7-Segments-Board for Embedded Systems
Design and Implementation of 7-Segments-Board 1.0 – An Extension Module for Embedded System Prototype Introduction When developing embedded systems, it would be helpful if we could have a module for monitoring purposes. For instance, let say that your system has to process data streams. In the testing and verification step, we need to compare each input and output bytes to verify that your system is doing right. Having a monitor module is surely a great help for engineers. Some development board has monitor module integrated, such as Altera UP1X FPGA Development Board. Inspired by its usage and benefit of such a monitor, 7-Segments-Board 1.0 is designed as an extension module for embedded system prototypes. Description 7-Segments-Board 1.0 is a low-cost, low-power MCU extension module for monitoring purposes. It aims to help engineers doing the firmware testing and debugging on hardware prototypes. For those who build microcontroller prototype devices from scratch and do not have access to sophisticated debugging instruments, using this module would make the testing and verification process less painful. 7-Segments-Board 1.0 is designed for an 8-bit microcontroller system. Module Specifications The module specifications are as follows: Input: General purpose push-button (PB) switches (dry contact). Output: Seven-segments LED to…
