Andrei is back from his Christmas hiatus and brings us a post introducing getting input from a UART.
Previously he had covered output using printf, a helper function called _write, and the HAL routine to send data out of the UART. This time we use the other half of the UART, a different HAL routine, _read, and getchar.

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 MoreUsing 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.
Read MoreThis 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 MoreThis 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 MoreThis 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 MoreThis 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 MoreThis time, let's blink those LEDs. Woah, slow down there Speed Racer!
Read MoreIn this post, Andrei looks at the code generated by CubeMX. Some of it is pretty ugly, but he gives a suggestion of how to co-exist with it.
Read MoreThis week, Andrei discusses how to acquire the sample code for the DISC1 processor board.
The trick is to download the CubeMX system from ST. We'll be using that in future examples, so follow along.
Read MoreDo you suffer from the devastating effects of DSA? There is hope, my friends: you can overcome your Data Sheet Anxiety with these great tips.
This week, Andrei introduces the documentation set for the STM32F4 DISC1 board, and discusses how to overcome the horrors of DSA.
