Understanding (ESP) Stack Trace Decoder

Projects General Guidance
1

Greetings.
I am trying to get a better grasp of what the output from the decoder is trying to tell me. As of now, my assumption is its telling to me to clean up my script, plug holes in memory leaks and learn better practices and techniques... but im an electrical engineer not a software engineer, so this C, C++ is learned on the fly, I have the retention to only learn things once, as long as i understand what, why, when, how, all that great stuff.
this project started off with X number of timers and X number of relays, my code has been dumbed down to just get it to complile and have a three timer starting point. it is nowhere near complete, but I would like to understand the errors im getting after upload better. Ive tried with multiple devices, to my surprise the supermini C3 runs the longest before error. So i will start there with C3 super mini Decoder Output > Backtrace then Wroom-32 Output>Backtrace.... and then yall can laugh at my terrible script

with the Wroom, there error is consistently coming when i split a string into several (seven) arrays. I am assuming this is a terrible practice and i am sure there is a better way to do it... but i just learned about pointers today and im self taught through trial and error, so this is an error to learn from.

thanks in advance to anyone that even gets through all that. Im trying to learn but the add gets the best of me, im the kind of person thats handwriting style can change every couple lines on a page so i apologize if anything is hard to follow. and my serial outputs may not mean anything to you, but the make perfect sense in my head

The arguments of sscanf() must point to allocated storage. You need to add & to z1 and z7.

How do we get here? the back trace shows the reverse order of the calls that get to the exception. In this case the problem started with a call to sscanf() in your code.

Looking at the source code we see that you neglected to use pointers for two of the arguments. The system was not amused when you tried to use actual values instead of pointers.

OK, i think i get that, SSCANF wants the memory address of z1-7, so, correct me if im wrong, in order to use the value of those variables down the road, i would need to use them as *z1 *z2... *z7?

4

No, you just use z1 - z7. The references in the sscanf() tell it were to put the result. Function calls can use values or references. In the first case a copy of the variables actual value is passed, in the second a pointer to the variable is passed and the actual variable can be changed.

For example...

5

in addition to & to pass the parameter addresses to scanf() as pointed out by @oldcurmudgeon

int z1,z2,z3,z4,z5,z6;
char z7;
sscanf(rly1.c_str(),"%d,%d,%d,%d,%d,%d,%s",z1,&z2,&z3,&z4,&z5,&z6,z7);

z7 is a char not a char array - use the %c conversion specification, e.g.

int z1,z2,z3,z4,z5,z6;
char z7;
sscanf(rly1.c_str(),"%d,%d,%d,%d,%d,%d,%c",&z1,&z2,&z3,&z4,&z5,&z6,&z7);

I assume rly1.c_str() contains comma seperated data

Yes, eventData a couple functions below handles timer edits, [creation], [deletion], state changes. Writes the data to comma delimited string, and writes the string to SPIFFS file timer_#.txt

While this section is/was originally, intended to be a function that pulls data from spiffs and puts it in corresponding arrays id, state, h:mON, h:mOff and timer name...
Eventually it should control 7 timers and 9 electronic value. Primary pump, spa pump, booster pump, vacuum pump, waterfall1-4 pump, waterfall3-7 spa over flow pump
And the valves that control water flow from intake and return, roof mount water heater, water slide, fountains etc.
This is my first attempt at programming anything remotely complicated, all I've done to this point are addressable LED controllers, wifi garage door openers, wifi relays, motion tracking can lights, RF IR cloners. I could do this project much faster with hardware logic and a few momentary and latching buttons, but I want a web gui and maybe touchscreen
