CubeMx Code generation of Timer Config -- Prescaler Bug with LL

[jherrmann1]

Hello everyone,

When configuring the timers via the MxGenerator, I noticed the following strange behavior.

If you use the LL, the code for the prescaler is generated strangely.

When setting Prescaler = 2-1, the correct code is generated when using the HAL. When using the LL, however, a substration is performed between two enums, which makes no sense.

This behavior is shown in the following screenshot.

However, if you set the prescaler to 1 directly in CubeMx and not to 2-1, the code is generated correctly.

I suspect a bug in the code generation.

The following versions are used.

STM32CubeIDE Version: 1.13.1

MCU Reference: STM32H563ZITx

Firmware Package: STM32Cube FW_H5 V1.1.1 

 

I hope for a confirmation of the bug and an adjustment in a next release.
Many thanks in advance!
