Let’s test what STM32F4xx devices can do. I have all “4 speed families” at home so why not to try it how fast we can go. By default, for those who don’t know max frequencies for STM32F4xx devices, they are in list below: 84MHz: STM32F401 MCUs, including Nucleo-F401 board 100MHz: STM32F411 MCUs, including Nucleo F411 board 168MHz: STM32F405/7 and STM32F415/17 MCUs, including STM32F4-Discovery board 180MHz: STM32F427/29 and STM32F437/39 MCUs, including STM32F429-Discovery board Ok, we have everything provided, let’s test how far...
CMSIS files from ARM provides ARM Math functions. There are also PID controller functions in different formats for f32, q31 and q7. This tutorial/project will talk about how to implement PID controller on STM32F4xx using PID functions from ARM. PID Controller Fast about PID controller. PID stands for Proportional-Integral-Derivative controller. This is a control loop feedback mechanism widely used in industrial control systems. It calculates the error between measured value and the desired setpoint value. According to the error, it...
After first FFT project, I’ve decided to make a simple snake game. Basically I’ve made it in Labview first for my partial exam at the university. It looked great so why not port it also to STM32F429-Discovery board which has everything already prepared for us. You just need USB OTG cable and external keyboard to drive snake and you are ready to play. Snake game Features Works on STM32F429-Discovery board Supports external keyboard using USB HID Host stack on STM32 Supports...
