sync_all_digits_from_values()

void sync_all_digits_from_values

(

void

)

Synchronize all input variables' digits arrays with their current values.

This function updates the digits array for all input variables based on their current value field. Useful after loading values from EEPROM or other external sources that modify the value but not the digits.

update_values_from_new_value()

void update_values_from_new_value	(	struct powrms_variables *	input_var,
		double	new_value )

Update the digits array based on a new value.

Parameters

input_var	Pointer to the variable structure to update
new_value	The new value to set (will be clamped to valid range)

update_values_of_digit()

void update_values_of_digit	(	struct powrms_variables *	input_var,
		uint8_t	increment_pos )

Update the value of a specific digit in the input variable.

Update the value of an input variable based on digit increment.
