This is a maybe stupid question but I cannot find a good (for me) explaination of how to use them. What the acronym is meant for?
I see in the docs

'The peripheral initialization is done through HAL_PPP_Init() while the hardware resourcesinitialization used by a peripheral (PPP) is performed during this initialization by callingMSP callback function HAL_PPP_MspInit().The MspInit callback performs the low level initialization related to the different additionalhardware resources: RCC, GPIO, NVIC and DMA. '

but I am still a bit confused

thanks
