stop loop to overwrite

[truesamurai]

I tried digisparkkeyboard and it works fine. Now I want to ovewrite with another payload. But everytime I plug in the Digispark it starts to type text automatically, so I can not upload another payload to the Digispark anymore. How can I proceed?

Make sure you press Upload in Arduino before you plug the digispark in. The upload program should wait for it, and catch the bootloader before it runs the keyboard program, and upload the new sketch. If that doesn’t work, try a different usb port, or try doing it through a usb hub. some newer USB 3 ports have been known to struggle with digispark.

There are two ways to stop loop ovewrite -

1. If you want to run your payload once, then write it into the setup function of Arduino ide because when the board gets powered from USB then firstly the bootloader run, then it jumps to the main file where it runs the setup function because it runs only one time then the loop function because it runs continuously until the board is removed from the system.

2. If you want to put your code in a loop function, then add a loop after your instructions because it follows a linear way of execution.
   The loop is

for ( ; ; )
{
}

Thank You
