My blog for 4929C during spring semester 2023.
asynchronous serial communication: (RS - 232) Sender and receiver not at the same time. Sender is sending, receiver is keeping up.
synchronous serial communicaiton: (I2C, SPI, 1-wire) Hardware > synchronous on that level.
Serial Monitor: found on bottom of screen. If you click -> and it says something about the serial port being unavailable, then click -> again.
View -> Terminal If you’d like to close the serial terminal, then hover and click trash can.
Companies:
FFT: filtering out certain frequencies.
Load cell (w/ amplifyer): determine weight.
Either surface mount or through hole. Thin layer of copper w/ fiberglass in between.
Copper connects > pins Soldier mask > green Fiberglass is everywhere coppper isn’t. pads: places where traces end. (insert image of trace and pad)
JLC PCB - factory makes circuit boards.
Paperbased circuit boards: FR1 Fiberglass: FR4
white - silk screen - labels
via: hole with nothing in it. Plated holes that makes the transition from bottom to top.
refdes
22 gauge wires. Solid wire: bend it and it stays. Stranded: looks like a tiny rope.
Keep soldiering iron temp in the middel 325°
Drop of soldier on tip of iron > helps heat the componenets. Tinning the tip/wire.
