Upload the first firmware

After installing everything we need, we configure Thonny to program in micropython OBJEX Link. First of all, go to Tools->Manage Plug-ins..., and install esptool.
Now connect OBJEX Link to your PC, and go to Tools->Options... and select the Interpreter Tab.
Install micropython firmware on OBJEX Link.
After the installation checks the correct functioning through the shell, we write a simple command print("hello") to verify if the firmware was installed correctly.
