I want to know, what is the difference between stmcube and SPL? Has SPL replaced by stmcube? or stmcube is something above the SPL? cause I think there is another thing called HAL library!
Also, when I want to use CMSIS-Core I should use which one of them, If I like to have low level access to registers?
I have stm32f40vg discovery board that I bought 4years ago, and like to use CMSIS-Core for programming, but I understood SPL is outdated and not supported for now! So what is the alternative for SPL? Or can I use SPL yet?
