What good is a UART? Why is it the second thing I get set up? (The first being the ubiquitous blinking light.)Read More
This week Andrei explains how to get a UART working using Cube. How to get printf working. And introduces the newlib standard library.
This is Andrei's final blog post of 2016, and it'll be useful for your Christmas break project where you learn about ARM processors using CubeMX and ST's Discovery board.Read More
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 More
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.Read More
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 More
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!Read More
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).Read More
