CMSIS-CMake

This CMake-based example project runs on a B-U585I-IOT02A development board from STMicroelectronics. The example code was generated with STM32CubeMX.

Quick start

1. Install Keil Studio for VS Code from the VS Code marketplace.
2. Clone this repository (for example using Git in VS Code) or download the ZIP file. Then open the repository folder in VS Code.
3. In VS Code, open the CMSIS View and then the Manage Solution dialog to select the target board and one project.
4. In the CMSIS view, use the Action buttons to build, load, and debug the example on your hardware.

Example Description

The I/Os PH.07 and PH.06 (configured in output pushpull mode) toggle in a forever loop. On the B-U585I-IOT02A board these I/Os are connected to LED7 and LED6.

In this example, HCLK is configured at 160 MHz.

Note

1. Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds) based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower) than the peripheral interrupt. Otherwise the caller ISR process will be blocked. To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
2. The example needs to ensure that the SysTick time base is always set to 1 millisecond to have correct HAL operation.
