Detailed Description

Contains the code to handle FIFO buffers for sensors, work with the SD card library. The header file also contains important data structs.

Function Documentation

dataLoggerTickFunction()

void dataLoggerTickFunction

(

pointers *

pointer_struct

)

Construct a new thd function object to log data to the SD card.

Parameters

arg	Contains info on the ring buffers containing the data and mutexes protecting it. This allows data to be passed to the function from another file.

sd_file_namer()

char* sd_file_namer	(	char *	fileName,
		char *	fileExtensionParam
	)

Creates the name for a file to be written to SD card.

Parameters

fileName	Pointer to char[] containing intended name of file. Do not include number or file extension at end of name. Make sure this is longer than it needs to be.
fileExtension	Pointer to char[] containing the file extension for the file.

Returns

char* Pointer to inputted char[]. It now contains number (if duplicate file existed) and .csv file extension.

Variable Documentation

flush_iterator

int32_t flush_iterator = 0

Logs data to 1 line of a specified .csv file on SD card.

Parameters

dataFile	File on SD card. Object from SD library.
data	Data structure to be logged.
