Discovery: UARTs Part 2 - Connections
Using the UART on our Discovery board requires a little extra hardware before we can use it for debugging.
This week, Andrei reviews some of the ways to hook the Discovery board to your PC.

Last time I explained the basics of what a microcontroller timer is and gave an overview of how timers are configured.
This time I’ll walk you through how to configure an MSP430 timer. We’ll use it to blink a light! (By now you’ve probably realized that most embedded system demos involve blinking a light. I’m pretty sure the singularity will look a lot like a rave.)
Read MoreDiscovery: UARTs Part 1
This week, Andrei introduces the UART. A useful data communications peripheral with a long history.
Follow along as Andrei gives the low down on bits and bauds, hardware handshakes, and inverting buffers.

A conversation about careers led me to realize I'm not sure what I want to be when I grow up. I started thinking about it from a different perspective.
Read MoreDiscovery: Button Interrupts
This week, Andrei discusses how our button can be used to generate an interrupt. Other examples include engine management computers. What things should you look out for when using interrupts.
Don't miss the photo at the bottom of the post for a useful hack.
Read MoreDiscovery: Follow The Bouncing Bit
This time, Andrei looks into switches, their bouncy nature, Schmitt triggers, hardware, and software debounce techniques. Join us for a look into the resistors and capacitors leading to port PA0. See oscilloscope traces in black AND white! All of this and more in this embedded.fm blog post!

Discovery: Buttons
This week Andrei is writing about buttons. First a bunch of the background stuff that goes along with buttons, how the positrons scoot around and finally make it to the processor. Then he takes a look at the HAL code used to read the button position.
How hard can it be? Well sit down and get comfortable, this won't hurt a bit (we'll leave the hurting bit for next time, Bwa ha haaaaa).
