| #define CHOOSE_DT_PRESCALER | ( | deadTime | ) |
Macro to choose Timer4 dead time pre-scaler based on the dead time.
This macro determines the appropriate dead time pre-scaler for Timer4 based on the provided deadTime value. The deadTime is expected to be an integer value representing nanoseconds.
The pre-scaler is chosen based on the following conditions:
| deadTime | The dead time in nanoseconds. |

| #define F_HST 64000000UL |
| #define FAST_ACCESS | ( | register_address | ) |
Assign a specific memory address to a variable for fast access.
This macro is used to specify the memory address of a register for fast access, directly instructing the compiler to place the variable at the given address. When parsed by IntelliSense in VSCode, the macro is defined as empty to avoid IntelliSense errors.
| #define FORCE_INLINE inline __attribute__((always_inline)) |
Macro for forcing inline expansion of functions.
This macro ensures that a function is always inlined by the compiler, overriding the compiler's own decision process. When parsed by IntelliSense in VSCode, it is defined as a simple inline to avoid IntelliSense errors. For actual compilation, it includes the GCC-specific always_inline attribute to enforce inlining.

| #define SPEED_CONTROL_CLOSED_LOOP 1 |
| #define SPEED_CONTROL_OPEN_LOOP 0 |
| #define SPEED_CONTROLLER_MAX_INPUT 255 |
Maximum Speed Reference Input.
This macro specifies the maximum speed reference input value that the speed controller should consider which corresponds to the highest possible reading from the ADC This is by default 8 bits as only the top 8 bits of the 10 bit ADC is being used. This corresponds to a value of 255.
