ESP8266 Community Forum

- Wed Jul 18, 2018 10:42 am #77164 Around Two Years ago I used an ESP8266EX to control a light switch. It worked great, and all was good.
Last week a friend ask me to help set up a garage door opener and I had some more ESP8266EX’s so I started to work.
The ESP8266EX I am using is a Manufacturer: e0 Device: 4014
The FTDI is a 1232.
The IDE is Arduino 1.8.5
The ESP lib is esp8266 Community 2.4.1
The ESP Lib Selected is “Generic ESP8266 Module”
The test script is:
void setup() {
pinMode(0, OUTPUT);
}
void loop() {
digitalWrite(0, HIGH);
delay(500);
digitalWrite(0, LOW);
delay(500);
}

Everything looks good. I can load the script. It reaches 100% then the red light goes very dim and that is it. Nothing…
I reboot, 50% of the time the red light is bright, and sometimes I can get some console logging that has this:
Ets Jan 8 2013, rst cause :4 Boot mode:(3,7)
Wdt reset
Load 0x4010f000, len 1384, room 16
Tail 8
Chksum 0x2d
Csum 0x2d

Any Hint as to what I am doing wrong?

then the red light goes very dim and that is it.

How do you know that your power supply is not the cause?

- Wed Jul 18, 2018 12:53 pm #77213 The Power is from the FTDI. I tried Two ftdi1232 and two different PC's

- Wed Jul 18, 2018 1:33 pm #77214 It has been my experience that the FTDI does not have enough + 3.3 volt power to operate the esp8266 especially if it is being supplied by the 232 chip.
