This week, after some more reading about the board and the connections and also some more reading on PCB design, I started using Kicad. Which is a very powerful PCB design software and it can be used for highly complex projects. After watching a few tutorials online and going through Read more…
This week which is my third, here at Aeste, was more about reading and understanding the current board. I started the week by redoing the Board Architecture that I worked on last week. At the time I did not fully understand what was asked, so I ended up doing it Read more…
This week I started going through the sample codes and also the previous interns codes and tried to master them. It was hard at the beginning to understand the latest integrated project. However, once I studied the individual parts of the code separately it all started to make sense. In Read more…
This week, I started my internship with Aeste. The week did not start well for me as I was not able to cover all the pre-internship material that was assigned to me by Dr. Shawn. After being scolded by him on the first day, I had an even bigger task Read more…
By SD card working as stated in the title, I actually meant that it has only successfully established a connection to the SD card, and is far from being able to write to or read from the SD card. The connection is verified by sending a reset command to the SD Read more…
This week I continued my attempt to establish a connection with the SD card. The first thing I did was to check the connection in the existing, and I found one of the pins was connected incorrectly, which is SDI2. The only option I found was to route it to pin Read more…
After successfully integrating the FPGA code with ethernet and USB serial, I proceeded to create a test firmware to establish and verify a connection with a micro SD card. The first thing to note about this project is that the SD card is connected to the PIC32 through the FPGA, Read more…
The FPGA project has been succesfully integrated into the current project containing the usbcdc and ethernet. Now the test firmware has working ethernet, usb serial port, and also successfully configures the FPGA. My attempt at integrating the FPGA project with the other two did not work initially, with the result Read more…
This week I started by trying to modify the FPGA code so that it would transfer in chunks of data rather than all in one go. Turns out a lot of the codes are not needed so Dr Shawn rewrote everything into less than 10 lines, this time using the Read more…
The FPGA is now configurable using the pic32mz. The cause of the problem was identified as being the clock to the FPGA not being set, and also the ucf file declared an unconnected pin, J13 as the clock pin. The problem was solved by enabling REFCLKOx in the Harmony Configurator, System Read more…
