UPDATE.<\/strong>\u00a0 I found the reason for the below exception:\u00a0 I was using too much time in processing the software interrupt (ESP8266Interrupt library) in loop().\u00a0 I was doing some A-D conversion to get the LiPo battery voltage status and evidently used too much time.\u00a0 So, THAT’S fixed.<\/p>

Now, I’m getting very weird stuff happening when I’m testing for long periods of time:\u00a0 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).\u00a0 Nice, huh?\u00a0 Oh, and I got an Exception 0 panic – Illegal Instruction.\u00a0 Maybe I wrote so many times to the D1 Mini that I corrupted the memory?\u00a0 Jeez.\u00a0 \u00a0I’m starting to get a little discouraged with this project and I still have more to do.\u00a0 \u00a0I just want to make sure the hardware is sound so I can work on a PCB and send it off to JLCPCB.\u00a0\u00a0<\/p>

(The below is OLD PANIC INFO)<\/p>

I’m using Khoi Hoang’s ESP8266Interrupt library as the main “driver” in the code; all the data gathering is interrupt driven.\u00a0 Another chance to learn more about PlatformIO and debugging code, I guess.\u00a0 I found there’s an option in the platformio.ini file to filter and decode any exception that is thrown by the program.\u00a0 Below in bold is the output from the program (I hate calling it a “sketch”. )\u00a0 \ud83d\ude42\u00a0 \u00a0It gets the reading in degrees from the MLX90316 angle sensor, that works great (albeit a bit power hungry).\u00a0 Then I enable interrupts to get a count of reed switch closings from the anemometer, get the count, and turn off interrupts.\u00a0 Hmm, maybe that’s the issue?<\/p>
