SDCard Working and Integration

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…

Attempt at SDCard and DHCP.

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…

Ethernet and SD-Card Connections

In the first two weeks of the project I was reading and trying to grasp the basics of PCB design and KiCAD. This week I put this knowledge…

Setback in Bitstream reading

This week was one where a big setback was experienced in the stack of code for bitstream reading. The stack was then analysed to find the overhead in…

Minor Modifications

The week was spent trying to look for ways to optimize the file upload time to suit the required objective having made some strides on that path during…

Full speed SD card reading

The week was spent in continuing the ground work done on the Synchronous USART to optimize the Reading process which will subsequently program the FPGA. After solving the…

Continuing Optimization

The optimization of the firmware continued with the focus being on the SD card reading stack. A look into the USART’s synchronous mode functionality was also taken to…

And the optimization begins!

Following the completion of the Ping-Pong Upload mechanism, its time to step forward to system optimization for the PIC firmware. This includes many separate portions looked into during…

A bit more writing and a lot more reading

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…

Functional File Upload with Base64 decoder and CRC checksum

This week ended up being highly productive as it culminated into the completed functionality of the file upload system with Base64 decoder and CRC support. However, it was…

Plans to Integrate the Base64 Decoder and Activating the CRC in the SD Card

The reason why the Base64 decoder is not working is because the buffer for storing the bit is a bit too short, I changed the buffer into a…

Text Area Input and Base64 Decoder

My next task would be to work on making the HTTP to upload the data in data-form instead of file form. I had the text field input integrated…

Deeper into the realm of SD cards

After scratching the surface into the world of SD cards and how they store data, almost all of the week was spent into trying to figure out as…

SD Card Inactive State

During the process of trying to write my own MDD stack, I found a comment in the code given by Microchip. It states: //Check if all attempts failed…

HTTP File Upload & Text Field Input Working

I recheck my functions to make sure that the three functions are doing the same thing as the one function. It turns it should be. Then, after some…
