I am having an issue with the ESP8266 board. I have an application running on it however it will not restart if I disconnect the power and power it up again. If I power it up multiple times I can sometimes get it start the application. Most of the time I have to recompile to get the program to restart. I am planning on installing it in an inaccessible location and will not have the capability to recompile.
I am using the A0 and GPIO0 pins along with the OV5642 camera.
Is there something I can do? Is this a normal function of the board? Is there an update to fix this problem?
What other GPIO pins are available on the ESP8266 board if you are using the OV5642 camera. If GPIO0 is not a good pin to use which is? I need to test when an input goes from low to High.
Question 2: What is the voltage range for the Analog pin? A0
SO:
What GPIO can I reliably use to test when a voltage goes from low to high. This is an Anemometer whose signal is High to low to High. I have no control as to where it will be at boot. Sitting at the top of 35 foot mast.
If I connect to GPIO0 and the input is sitting on low the program will not start. Looks like the same would be true for GPIO2.
