Hard resetting via RTS pin…
I’m newbie use nodemcu, and i have errors when upload the code, i’ve reset it but still not working, what should i do for fix it?
That’s what a normal upload looks like. These aren’t error messages, they are are informational messages. The “Hard Resetting …” message simply means that the device is rebooting so that it will load and run the new code.
This is your error message.
It occurs because the code you are using doesn’t correctly declare the interrupt ISR function. This isn’t a problem with earlier versions of the ESP core, as they were tolerant of this omission, but later versions are more strict about this.
To fix the issue you need to add ICACHE_RAM_ATTR to the name of your ISR, like this:
void ICACHE_RAM_ATTR yourFunctinName()
Also, the ISR function needs to be before your void setup() otherwise you’ll get a ‘not declared in this scope error’.
A quick search of google or this forum would have revealed all of this information, as it is not a Blynk specific issue.
