Group Project¶
The requirements of the group project is to:
- send a message between two projects.
Me and Adam Stone worked together and decided to send a message across the 2 XIAO boards using UART and send a message between two Pico Ws using a wireless network.
Note that the first part, uART, is really similar to the individual project. So, I have also included a couple of links to the group project in my individual section.
My Part¶
I edited the code for the UART communication because I saw that one of the while loops did not work properly and was not sending out the message “hello” over and over again. So, I deleted all of the extraneous parts of the code and only kept the simplest part that sent out the message.
Milling¶
In KiCAD, I designed the board in which the RX and TX pins of two Xiao picos are connected to each other. When I was milling the board, I ran into some problems.
- The first time, the machine did not work, so I switched to a different Othermill machine.
- Next, the bit went too deep into the board and completely tears through it.
I also accidentally dropped a bit and broke it the process.
Finally, under the guidance of Adam Durrett, I finally made a working board.
After making sure that the traces are wide enough, I milled another board and soldered on the right pieces. Read more about the complete process here.
and milled the board for that process. I also soldered the parts on to the board.
