This is my fourth week internship in AESTE. This week my task is to send a string from PIC32 to desktop. Then, using wolfSSL encrypt function to encrypt the string and type out again to desktop. After type out, using our precreate private key to decrypt and check whether same Read more
Last week I had tested the keyboard typing speed by different buffer size and different CPU frequency. After collected the data, I had plotted 2 graph to make a conclusion. PIC32 keyboard typing speed is won’t be affected by changing buffer size or CPU frequency. The typing speed is remain 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
Yeah! I just finished the first week of my internship at AESTE Works. What a great experience so far. On my first day, Dr Shawn had introduced to me about company rules and sent me a few links to study about Git. Git is the most widely used modern version Read more
This week was an intense week. The week started with me demonstrating the modem to Dr. Shawn and with a short check of the modem’s code by him. He noticed that there was no obvious state machine in the code which prompted a rewrite of the code to include one. Read more
This week, I finished a working version of the modem which now supports sending data and properly detecting when there is a disconnect to allow reconnecting properly. There are however, a few limitations as of now. One of them is that for some reason on the current firmware, I am Read more
This week, I wrapped up work on separating the USB features of the firmware which consists of the HID Keyboard and CDC Debugging Console into 2 seperate files together with 1 USB base file where functionalities are shared. These were written to resemble a library which helps to simplify usage Read more
This week, I was able to pinpoint the reason behind the erratic behaviour of the board. Upon rereading the documentation for the Harmony USB Libraries, I found out that in particular for the PIC32MZ family of microcontrollers which includes the board that we were working on, the buffers that are Read more
This week, I explained to Dr. Shawn about the fact that the USB code managed to work on the PIC32MX but not the real boards in which he suggested to reduce the clock speed of the real boards to match the ones on the PIC32MX as it could be some Read more
After having much fun with the PIC32 Starter Kit, I am currently moving on to the real boards. As expected, the previous USB code that worked on the starter kit no longer work properly on the real boards. Got the 2 LEDs to work on the boards and hence started Read more
