For my second week at AESTE, I was assigned to design and implement a GPIO using the wishbone protocol. The wishbone protocol is a standard method that is used by many processors to communicate to their IO devices. It is a format that uses several several signals in its BUS Read more…
My First day started with introducing the workplace and the project I’ll be working on followed by a quick introduction about Verilog and the necessary tools that I need to use to do my work. For this week the goal will be to wrap up all the learning that I Read more…
Last week, I was given the opportunity to explore several programs that I needed to use for my upcoming project. These were GIT, Icarus, GTK waveform viewer and finally ISE. I learnt how to store and manipulate files from a repository through GIT. I would recommend GIT to anyone who Read more…
I managed to set up physical layer for ethernet connection after solving the error which came from the .c file that end with ‘#endif’. I just needed to add an empty line after ‘#endif’ and that solved the problem. When the board was powered up, the LED D8 was blinking, Read more…
In order to allow communication between PIC microcontroller and PC, UART communication needs to be set up. I wrote a program to send data byte from PIC microcontroller to PC which the output was displayed through Minicom, a hyper terminal for linux. At first, the displayed output was gibberish. This Read more…
My first week in the company, I was briefed on the project that I need to conduct throughout my internship. My task is to work on the PICDEM.NET2 development board which uses PIC18F97J60 microcontroller. The objective is to write a program which is able to download file from internet via Read more…
I tested out the code I had already written and found out that the power up sequence was not working as expected. After consulting with my supervisor he advised me to enable pull-up resistors in port B and test the input and outputs for the each pin. By setting the Read more…
After adding the software SPI, I started out writing the program. There are four working modes in SPI and the SPI timings for Mode 0 is the proper setting for the SD Cards. After setting the mode I started defined the values for the commands that are to be used. Read more…
I was still working on the SD card this week. I took up from where I left off and started with setting up the SD card. I soldered the pins onto the little board for holding the card. This board has a pre-made insertion point for the card and which Read more…
I started on the SD Card portion of the project. The objective of this is to read and write to and from the card, and finally to download data from the network and store in SD Card. I started my research on SD Cards. From this study I found that Read more…
