In my previous article I showed how we designed the STM32 firmware for our simple WiFi scope. Now it is time to explore the server code running on the Onion Omega 2+ and the graphic client!
Have you ever thought about designing an oscilloscope? What about a WiFi scope? In this series of articles I show how to design a very simple low-frequency WiFi “oscilloscope” using an Onion Omega2+ and a STM32 microcontroller.
In this article I show a simple C library I wrote for the STM32 to help debouncing keys. It is completely non-blocking and also includes a nice auto-repeat feature with progressive speed! I wrote this library to complete an assignment
In our previous articles we saw how to create threads on Synergy/ThreadX and took a look at the RTOS basic structure. Now it is time to talk about a very common mistake when programming in multi-threading systems which is the
In our last article we saw Renesas Synergy product line and how to create threads in ThreadX by using E2 Studio. In this article we are going to look at some details regarding ThreadX operation and take a look at some
Microcontroller applications are getting more and more complex, using lots of memory and complex peripherals. This complexity increase makes it necessary using software tools to ease application development, so that the designer or designing team can focus their effort in
Hello there! This is just a quick post on how to use a color SPI LCD (with a ST7735 controller) with your STM32L4 microcontroller. I am using Oleg Yakovlev’s library with just some minor modifications (mostly to adapt it to
This is a video from my presentation at the 2008 C&C++ Embedded Systems Conference held in São Paulo (portuguese video)!
