UPDATE. I found the reason for the below exception: I was using too much time in processing the software interrupt (ESP8266Interrupt library) in loop(). I was doing some A-D conversion to get the LiPo battery voltage status and evidently used too much time. So, THAT’S fixed.
Now, I’m getting very weird stuff happening when I’m testing for long periods of time: the temperature probe occasionally reads WAY high (300 degrees?), the time acquired from the DS3231 loses the Time Zone I’m in, and the OLED display gets scrambled a display and I have to re-initialize it from time to time (still in progress, that fix is). Nice, huh? Oh, and I got an Exception 0 panic – Illegal Instruction. Maybe I wrote so many times to the D1 Mini that I corrupted the memory? Jeez. I’m starting to get a little discouraged with this project and I still have more to do. I just want to make sure the hardware is sound so I can work on a PCB and send it off to JLCPCB.
(The below is OLD PANIC INFO)
I’m using Khoi Hoang’s ESP8266Interrupt library as the main “driver” in the code; all the data gathering is interrupt driven. Another chance to learn more about PlatformIO and debugging code, I guess. I found there’s an option in the platformio.ini file to filter and decode any exception that is thrown by the program. Below in bold is the output from the program (I hate calling it a “sketch”. ) 🙂 It gets the reading in degrees from the MLX90316 angle sensor, that works great (albeit a bit power hungry). Then I enable interrupts to get a count of reed switch closings from the anemometer, get the count, and turn off interrupts. Hmm, maybe that’s the issue?
