C is for Cookie, and also C.
Read MoreLove Notes to Newton
Not that long ago, tech pundits would run articles like “The biggest technology flops in history” and “Apple’s Worst Products and Biggest Failures”. These lists would always contain Apple’s Newton handheld computer. Was it a failure? I don’t think so, but you can decide for yourself.
ESE101: Switching from Assembly to C Part 4
CCS before C? Yeah you know me.
Read MoreAn Introduction to BCD
It’s 9:31, do you know where your bits are? A lot of real time clocks use binary coded decimal or BCD to store the time. BCD isn’t a common format but you will probably run into it at some point. This time, we look at BCD and how to convert it to binary.

I wanted to make a custom watch face for my Versa. It was kind of fun.
Read MoreA Conversation About Cyclomatic Complexity
Code should be as complicated as it needs to be, but no more complicated.

Andrei’s back. In this week’s post, Andrei looks at the weird world of octal. Where did that come from?
Read MoreTell Me About Your Toolchain
This is not a simple post that will tell you exactly how to set up a tool chain that works for your development environment, target processor, and available tools.
Read MoreRanges in Array Initializers
This time, Andrei looks at initializing variables and the use of range specifiers when initializing arrays.
Read MoreMultiplying Math Libraries
Why does every compiler have their own math library?
Read MoreThe Case for the Default Case
In a previous post, Andrei discussed the switch statement. In this post, he gives a more indepth review of switch and then deeply dives into the default case.
Rather than just leaving it out, default can be used to detect the impossible. Read on to handle whoopses, neutrino hits, and beer. And remember, be assertive, but be kind to your future self.

Firmware update is very tricky, with many pitfalls.

Read MoreI Apply SPI: Good Vibrations
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 MoreI Apply SPI: Making Connections
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 MorePing Pong Buffers
If you haven’t heard of ping pong buffers or double buffering, read this. They aren’t difficult and you will wish you knew the right words during your interview.
Read MoreExceptional Code
In this post, Andrei explains an unexpected exception caused by following a pointer.
It's an exploration of the translation of C code into assembly and what happens when the compiler tries to figure out what you are doing wrong.
