I am attempting to make a change to an LED feature that i have been running for months. I modified it to use the ESP32 using the data from your esp 32 course. But today I tried to make a change and was greeted with this message when trying it compile prior to creating the .bin file. I have several .bin files that run this light feature and I can change the presentation by changing the .bin file using OTA. However, I tried to make a small code change and now I find that I am unable to to compile any of the sketches including the ones that have been working. The basic code for these sketches comes from your ESP32 course. But I get the same error trying to compile any of them. The .bin files that were created several months ago still work fine . Where should that file reside on a WIN10 machine? I found the file on my PC buried deeply in the ArduinoData folder.
I have a suspicion that this may have been caused by my recent change from the MS win10 version of the arduino system back to the generic 1.8.12 system. I have looked through the preferences.txt file but I don’t see any reference there. I would appreciate your input. I have no doubt it is probably another one of my frequent “senior” moments. Thank you
As I suspected, another senior moment. When I changed to the “real” Arduino version, I made the correct entries in the preferences.txt file but but failed to make the changes required in Boards Manager. Since changing sketches with .bin files that were already produced, I had no problems. However, when the code had to be changed, this prevented me from compiling correctly. Updating the Board Manager for the ESP32 fixed the issue but, of course, didn’t do anything for the “real” reason behind this whole thing.
