This week Andrei presents a pin 1 spotting guide. Chips, circuit boards, and connectors are all numbered, and this is your guide to figuring out what on your schematic is where on a circuit board.

This week, we take a look at the firmware involved in using the SPI bus. From the function calls to control the select pin then send out some data via the SPI bus, the form and specifics of the command structure for an accelerometer, and then we get some data flowing.
Busted data sheets, 16-bit values, and right handed chips - how can you pass this up?Read More
This time, Andrei blends together schematics and oscilloscope traces, pours over data sheets and diagrams, and sifts through the jargon of SPI.
The result is a richer understanding of SPI with a side of CubeMX parameters.Read More
Inigo Montoya: You are wonderful.
Man in Black: Thank you; I've worked hard to become so.
Inigo Montoya: I admit it, you are better than I am.
Man in Black: Then why are you smiling?
Inigo Montoya: Because I know something you don't know.
Man in Black: And what is that?
Inigo Montoya: I am not left-handed.
Man in Black: You are amazing.
Inigo Montoya: I ought to be, after 20 years.
Man in Black: Oh, there's something I ought to tell you.
Inigo Montoya: Tell me.
Man in Black: I'm not left-handed either.
Once we get into the nitty-gritty of SPI, there is going to be a lot of schematics and oscilloscope pictures that we have to figure out. Now is the time to get up to speed on schematic notation and oscilloscopes.Read More
