'HardwareTimer' does not name a type; did you mean 'HardwareSerial'?

[kunalpawar330]

I have installed the stm32duino core on my arduino ide and trying to detect frequency of input signal but I am getting this error. The code is also from examples->stm32duino examples->hardwaretimer->Input capture

Arduino: 1.8.9 (Windows 10), Board: "Generic STM32F1 series, BluePill F103C8, STM32CubeProgrammer (Serial), Enabled (generic 'Serial'), None, Low/Full Speed, Smallest (-Os default), Newlib Nano (default)"

A subdirectory or file sketch already exists.

Hi @kunalpawar330
You need to install 1.7.0 version of the core.
