Capacitive touch sensing for STMF103

Hello,

I am trying to implement a long 1D capacitive touch slide sensor or around 7 or more separate capacitive touch buttons using STM32F103. 

 

I read that the touch sense library is not available for F103. Is this correct? Does the F103 lack touch functionality? Does ST provide any means of implementing touch sensing with F103?

 

On Github / the net, I find an implementation for STMDuino, but no implementation in C using the current HAL or LL environment. 

 

What other libraries or examples of touch buttons for F103 are available or easy to port?

 

Thank you & regards,

 

Christoph
