Specifies the programmer to use, common options are 'usbtiny' and 'avrisp2'. The default is 'usbtiny'.

Specifies the hex file to load to the board. The default is the currently installed version of Snek.

Use the 3v binary instead of the default 5v binary.

COMMANDS¶

fuseload

Sets the target fuse bits for Snek usage and then loads Snek to the device. This is the default command

load

Loads Snek to the device without first setting the fuse bits. Snek will not work correctly if the fuse bits are not set correctly, so only do this if the target has already had the fuse bits set correctly.

fuse

Sets the target fuse bits suitable for Snek usage. You must do this before Snek will work on the target device, although you may do it before or after loading the Snek system. You only need to do this once per board.
