Chronicles from our peeps.
For the most part of this week I was exploring new ideas, exploring Wt’s capabilities, debugging some annoying bugs, and designing algorithms for some objectives. First, let me start with the interface bug. Slow connection rendering bug When the interface was changed to the current one, a weird bug occurred Read more
Last week, I am still doing on contiki’s functions testing in my new porting microprocessor and platform. After 1 week plus of function testing, the basic functions are working in my porting microprocessor and platform. The process in contiki OS called protothread. All of those protothread are scheduled in cooperative manner. Read more
This week my job scope was about the TCPIP. I need to use the PICDEM.net 2 as a TCP echo server that listen on a TCP/IP socket and transmits back exactly everything that it receives. There are some demos in the microchip application library, what I have to do was Read more
For five weeks in row we have been working on the enhancement of the code. I really don’t know why it’s taking that much time. Is that what usually happens in any project developing?! Feel like we are in infinite loop… Hopefully we will reach the “break;” statement soon. Lol Read more
This week, I finally get the RISC-V Angel Simulator to run the C/C++ code compiled from the default RISC-V GNU compiler, which is specifically designed to compile files into ELF file that to be used with the RISC-V Spike and Proxy Kernel. I had verified that the bootloader extracted from Read more
This week I gained a deeper and clearer understanding about some terminologies and the flow within a compiler that I have posted last week. Frontend Basically it uses a parser to produce the syntax tree abstraction of a given source file. It will translate source codes into intermediate representation (IR) like Read more
This week, I had really a hard time with RISC-V Angel. It started with finding the bootloader code from the RISC-V Proxy Kernel, as the bootloader is the primary program/codes that needs to be load up before the main program actually runs. I searched all over the proxy kernel code and Read more
My task of this week is the configuration of FPGA. I had to configure the Spartan 6 XC6SLX9 FPGA in the slave serial mode, by using the USART port in the PIC18F97J60. This is something really new to me and web references are scare. Therefore, the only way is to Read more
In contiki os, there are a lot of functions predefined in the core file. During programming in contiki os, programmers require to follow the contiki programming style to create their own code. These functions are PROCESS_BEGIN(), PROCESS_END(), PROCESS_YIELD() and so on. All of the functions have its own uses but some of it only Read more
The stream of code bugs and necessary modifications continued running this week as well. I had to do some code modification, complete some features and solve some bugs here and there. This really took longer than I thought it would! Hopefully it will finish soon. Customizable BRAM size. I had Read more
