Arduino variable going blank after first pass.
- by user541597
I have an arduino sketch that takes a timet and when that timet is equal to the current time it sets the new timet to timet + 2.
For example:
char* convert(char* x, String y){
int hour;
int minute;
sscanf(x, "%d:%d", &hour, &minute);
char buf[6];
if (y == "6"){
if (hour > 17){
hour = (hour+6)%24;
snprintf(buf, 10, "%d:%d", hour, minute );
}else
if (hour < 18){
//hour = hour + 6;
minute = (minute + 2);
snprintf(buf, 10, "%d:%d", hour, minute);
}
}
if (y == "12"){
if (hour > 11){
hour = (hour+12)%24;
snprintf(buf, 10, "%d:%d", hour, minute );
}
else if (hour < 12){
hour = hour + 12;
snprintf(buf, 10, "%d:%d", hour, minute);
}
}
if (y == "24"){
hour = (hour+24)%24;
snprintf(buf, 10, "%d:%d", hour, minute );
}
return buf;
}
sketch starts for example at 1:00am timet is set to 1:02, at system time 1:02 timet == system time
my loops looks like this:
if (timet == currenttime){
timet = convert(timet)
}
From this now when ever I check the value of timet it should equal 1:04, however I am getting the correct value at the first run after the execution of convert however everytime after that my timet value is blank.
I tried changing the code instead of using the if loop I only run the convert function when I send for example t through the serial monitor, this works fine and outputs the correct timet after the execution of the convert function, So I figured the problem is in the if loop...
Any ideas?
