Schematics Completed

This week I spent most of my time finishing up the schematics. The updated board will have 2 complete SPI and 1 complete UART connection, between the PIC32 and the FPGA. The PIC32 pin...

Power Supply & Clocking

I started the week by looking at alternative power supply designs. The problem with the current design is that it utilizes 2 bulky linear voltage regulators. There are many single chip solutions for the...

Start PCB Design

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...

Third Week

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...

Proceeding to SD card

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...

FPGA now working

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...

TCPIP Stack Bug

This week I continue trying to figure out how to ‘download’ a huge file with TCP protocol. Set up a USB cdc com port to ease debugging. Fixing ‘init_b’ staying LOW. TCP Server looping...
