Not sure if anyone is interested but someone may find it useful… A fairly simple menu on the serial port to setup an array to be used for a weekly access schedule. the array can then be checked with the checkSchedule function.
i have a stuct that holds username data, one element is: Username.Schedule that is a byte array of 21. i chose this because its really easy to store on an SD card with the arduino EDB library.
This is added to your code to call the menu function, i have it in the add user and update user menu’s:
while (!addSchedule()) SPARK_WLAN_Loop();
it will continue looping until the function is finished and returns a 1 for done or -1 for canceled.
and to check the schedule i load the Username,Schedule into RAM (this is done when the fingerprint reader has checked the print and determined whos it is)
boolean a = checkSchedule();
if its true the the bit was set and the user has access if not then they are not allowed in
the functions are below
void printSchedule(uint8_t days) {
Serial.println("Day Time 00 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 00");
int a;
uint8_t day = 0;
while (day <= 6) {
day++;
a = days;
if (bitRead(a, day - 1)) {
