If it keeps resetting have a look in the code for any statements where the program can hang for a second. while(1) will do this ,while(::) I have seen as well. I suspect the watch dog timer is being triggered and that can be many things . Another one is to try to read an array but the index is out of bounds .
memory size should not matter.

Hi,
i had also problems with analograd. Now it works. First was to define the variable which keeps the analog value as uint.
Second was NOT to use (arduino) analogread. Instead to use the other (adc_read?) function from the SDK (?). I'm at work but later at home I can take a look what exactly it was.
Greetz, Bernd
EDIT: I think it was this: uint16 adc = system_adc_read();

Thanks Tytower... but the program is VERY simple... none of the described problem would likely occur...
Code: Select allvoid setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
Serial.println(sensorValue);
delay(1000);
} but I also did a run with the Watchdog disabled... same result..
