dSPIN.c file content

dSPIN.c is the library source file. It contains all the L6470 commands and the

implementation of other support functions.

It starts with the dSPIN_Peripherals_Init function which configures all the required

microcontroller peripherals (GPIOs, SPI) and it is called at the beginning of the main

program loop. The function considers signal assignments made in the dSPIN.h file.

The dSPIN_Regs_Struct_Reset function fills all the structure fields with default values.

The dSPIN_Registers_Set function programs all parameters into L6470 internal registers.

It uses pointer-to-structure as the input parameter, so the structure must be filled properly in

advance of this function call.

The dSPIN.c file contains all the dSPIN commands and the implementation of other support

functions. The code is well commented, please refer directly to the file for more details.
