Semantic MediaWiki
There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.This article explains what WDG is and how to use it through examples.
1. What is a HRTIM ?
HRTIM stands for High Resolution Timer. HRTIM is a highly accurate timer which can generate complex waveforms such as PWM, phase-shifted, constant Ton... with highly very fine timing resolution (184 ps on the STM32G4 series). In
1.1. HRTIM modes
Up-counters can operate in three modes :
- Continuous (also called Free-running) : it rolls over to zero when it exceeds the value
- Non-retriggerable :
- Retriggerable :
1.2. Block diagram overview
As we can see on the figure below, the HRTIM have a modular architecture. Let's have a look at each block :
- Block 1 Timer :
- Block 2 Crossbar :
- Block 3 Output :
- Block 4 Input :
- Block 5 Interface :
2. Configure the HRTIM to generate a simple PWM
2.1. Objective
- In this project, you will learn how to setup WWDG in STM32CubeIDE
- How to Generate Code in STM32CubeIDE and use HAL functions
- Create a simple application to test and periodically refresh the WWDG
- Verify the correct functionality on toggling LED
2.2. Creating the project in STM32CubeIDE
- File > New > STM32 Project in main panel.
2.3. Configure HRTIM
2.4. Generate project and edit main.c
The easiest way to generate the code is to save your current project : Ctrl + S
2.5. Compile and flash
- Click on Build button
- Click on Debug button (to run step by step)
- Or on Run button (to execute)
