I want to use standard peripherals library for stm32l476rg(stm32-nucleo). But I could not find it. I dont want to use HAL Library. Do you any suggestion?
ST doesn't have a "standard perhiperals library" for L4 as they used to have for other chips, but was discontinued and replaced by STMCube. STM32CubeL4.
However, ST does have Low-Level API. This is new, and is more similar to the old "std periph". These start with:
All of which are found in the STMCubeMX tool.
DSP library is found in CMSIS, not from ST, but from ARM. This is included in ST's library package though.
