I solved the problem by taking the switching statements out of the callback. I set a flag in the callback then change the status in the main loop.

I am having an issue with my esp32 and the app status getting out of sync. I am setting up a button to open my garage door. This needs to be a momentary button but I can't find one in Rainmaker so I am simulating it by turning a switch on for a few seconds then turning it off. This works, press the ...

I put my esp32 into deep sleep to save energy. Attached to pin 21 I have the anode of the led of an opto isolator and a 10k resistor to ground. The cathode of the led is connected to ground through a 330 ohm resistor. When the esp32 is awake I can make pin 21 go high of low as I wish. When the esp32...

I neglected to add that I'm using PlatformIO on Microsoft Visual Studio Code.

I have a newbie question. I have a file with code in it called test.txt. If I put this in the src directory and put an include statement in the .cpp file, it is compiled. If I put it in the include directory it compiles. If I put it in an external directory and put a search line in the c_cpp_propert...

Are you not able to do this in software on the esp32? Using your scaled down voltage, if the input is below reading*the multiplier * lower threshold treat it as 0 and if it above reading*the multiplier * higher threshold treat it as 1. Using a resistor divider and calculating it in software is much ...

Your voltage divider calculation is wrong. If you have 2 resistors as a voltage divider, call the top resister R1 (the one that is connected to the voltage to be measured) and call the bottom resister R2. Use R1/(R1+R2). This will give you the correct divisor, or 1/divisor to give you the multiplier.

I've been running Platformio with Visual Studio Code for some time. The Platformio documentation was accurate and complete, and I've never had a problem with compiling or uploading. But you do need to follow the instructions, particularly about NOT installing Arduino Core, and selecting Platformio I...

All examples I have seen for using sntp_init use a test on the year to determine if there is a valid date, but what happens if you use sntp_init each day to check the date/time, any difference will likely only be minutes or seconds so any test using the year will say that the date/time will be corre...
