This is my eleventh week of being an intern at Aeste Works. My main focus this week was to ensure that two way communication between the USB stack and lwIP’s TCP/IP stack was working as intended. The simplest way to achieve this was pinging the USB CDC ECM device and Read more…
This is the tenth week of being an intern at Aeste Works. Continuing from last week, I found a way to separate normal USB packets and networking packets. This can be done by checking the twelfth and thirteenth byte of the payload found in the readBuffer. Protocols such as IPv4, Read more…
This is my ninth week of being an intern at Aeste Works. This week was testing whether the lwIP stack had been configured correctly and whether the interface can be successfully initialized. To initialize the network stack in a lwIP single-threaded core, the function lwip_init is called and then the network Read more…
This is my eighth week of being an intern at Aeste Works. This week was about setting up and integrating the lwIP stack with the USB CDC ECM device. The device currently does not run with an operating system and so must be configured for the lwIP NOSYS mode using the raw Read more…
This is my seventh week as an intern at Aeste Works. This week was about figuring out which part of my USB CDC ECM code interfaces between the host and device in sending and receiving network packets so that I could integrate the lwIP TCP/IP stack later on. There are Read more…
This is week six of my internship at Aeste Works. After configuring the company’s board to enumerate successfully on a Windows environment, it was time to configure it on Linux. On Windows, the usb drivers loads according to the Vendor ID and Product ID which was for Microchip’s USB CDC Read more…
This is week five of my internship at Aeste Works. To move forward to what I have to do to implement USB CDC ECM class for ethernet over usb, I’d have to first migrate the USB CDC ACM demo from the PIC32MX which I had been working on last week Read more…
This is my fourth week as an Intern at Aeste Works. My main target this week was to configure the PIC32MX microcontroller as a Universal Serial Bus Communications Class Device that utilizes the Ethernet Networking Control Model (ECM) in allowing the exchange of Ethernet-framed data between device and host. The first Read more…
This is week three of my internship at Aeste Works. Three main tasks were assigned to me this week. First was to study on the programming & configuration protocols of three different FPGA’s namely Xilinx’s Spartan-6, Intel’s Cyclone and Lattice’s iCE40. Currently, the company’s own board incorporates the Xilinx Spartan Read more…
This is my second week in AESTE. This week I continue to workout the USB function in PIC32 starter kit. Before that, I had studied the USB theory in order to know how it works and how the USB device can communication with the USB host(PC). There are 3 stages: Read more…
