This week Dr Shawn has explained to me the internal registers of UART, SPI and TWI. Basically these modules has two registers: status register and data register. Status register, from its name we know that this register contains information about the state of the device. Data register contains the data Read more…
This week I am working with UART (Universal asynchronous receiver/transmitter). UART is a device that used for serial communication over a peripheral device serial port or computer. UART takes bytes of data and transmits the individual bits in a sequential fashion. UART consists of a data bus with several data Read more…
This week I worked on the UART communication. My task is to transmit and receive the bytes of data via the RS232 port of the PICDEM.net 2. Dr. Shawn gave me a brief on the process and introduced the minicom program to me, in order for me to verify whether Read more…
Following the functionality of the Base64 decoder and CRC checked writing process, it was time to move onto the next step to reach the objective set for the month. The next step is to integrate two specific portions into the current code; i) the Ping-Pong Upload mechanism and ii) Reading Read more…
It was an up and down week of sorts. It didn’t start off but as the week wore on and with some crucial help/advice from the supervisor and colleague, the desired task was achieved, although it is yet to see if it was the best solution to the problem at Read more…
This week had a lot of testing going. First of all UART is 90% done. It has been tested by simulation and on FPGA communicating with the PC through Minicom. I’ve faced a very interesting issue while testing UART on Spartan 6 ATLYS board. My UART can transmit data to Read more…
Running to the bus-stop to try to catch the 9:00am UCSI bust before it runs away, all I could think was “God, I don’t want to be late on the first day!”. But the butterflies in my stomach gave me enough of a kick to get on the bus in Read more…
This week I’ve finished the second version of SPI. I basically adjusted the formatting of the code to be more professional, easier to read and interpret and better commented. My guide is the code for AEMB, it’s formatting, nomenclature and comments. I’ve come across a bug in SPI. Apparantely the Read more…
This week I finished up the Rx portion of the UART device that follows the RS232 protocol. I was able to implement it onto the Spartan3 board. When I first tested it, I was a little confused because I didnt know that the letters were represented in ASCII code. My 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…
