I'm trying to build the software side of an Automatic Blind Controller on Thingiverse, but having am trouble with what I think is repetitive rebooting, based on the serial monitor output:
17:53:28.964 -> ets Jan 8 2013,rst cause:2, boot mode:(3,6)
17:53:28.964 ->
17:53:28.964 -> load 0x4010f000, len 3456, room 16
17:53:28.998 -> tail 0
17:53:28.998 -> chksum 0x84
17:53:28.998 -> csum 0x84
17:53:28.998 -> va5432625
17:53:28.998 -> ~ld
17:53:30.728 ->
17:53:30.728 -> ets Jan 8 2013,rst cause:2, boot mode:(3,6)
17:53:30.728 ->
17:53:30.728 -> load 0x4010f000, len 3456, room 16
17:53:30.728 -> tail 0
17:53:30.728 -> chksum 0x84
17:53:30.728 -> csum 0x84
17:53:30.728 -> va5432625
17:53:30.728 -> ~ld
It looks like this is just the bootloader restarting, it doesn't get far enough into the Arduino setup() function to produce any serial output.
How should I debug this?
- Arduino Blink sketch works fine - blinks LED at a sensible rate
- Arduino DigitalReadSerial works fine - outputs button status on serial port
- Even ESP8266WiFi/WiFiScan worked which I thought might be the problem.
- I'm suspecting a power issue (despite using an external power supply), so I've started commenting out much of
void setup()to limit what else starts up to no avail:
Extract from BCV2_02_Blank.ino:
void setup()
{
// Debug console
Serial.begin(9600); // I've also tried 115200 to match the bootloader, but ultimately nothing comes out
//NeoPixel library
pixels.begin(); // This initializes the NeoPixel library.
pixels.setBrightness(200);
if (digitalRead(downButtonPin) == HIGH) {
Serial.println("Resetting...");
flash_LED(8,String("Green"));
delay(3000);
resetAll();
}
Serial.println("Initiallising...");
//Turn on led as boot status
pixels.setPixelColor(0,255,165,0);
pixels.show();
delay(2000);
...
- Continuing with my suspicion of power issues, I've begun to comment out anything that may be initialised before
setup()runs:
Extract from BCV2_02_Blank.ino:

This still doesn't seem to do the trick. How does Arduino IDE choose what to libraries to link? What's the equivalent of a Makefile in Arduino-land.
What else should I try:
- Code the whole thing up from scratch, and adding libraries as I go until it breaks?
- Throw the D1 mini away as it feels like a poor quality knock-off and get another one (but not guarantee that'll be any better)?
