NAME¶

snek-lilypad-big-big-install - Install larger version of Snek to Arduino ATmega328 board

SYNOPSIS¶

snek-lilypad-big-install [OPTION]... [COMMAND]

DESCRIPTION¶

snek-lilypad-big-install installs the larger version Snek programming language on an Arduino board with an ATmega328, overwriting the boot loader. This version of snek provides support for a few extra functions, 'input', 'float' and 'int'. As a consequence, it does not leave room for the Optiboot loader and must be flashed using a separate programmer dongle.

OPTIONS¶

-isp <ISP model>

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

-hex <snek.hex>

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

-mcu <MCU name>

Specifies which micro controller to expect to find on the board. Some boards have m328 while others have m328p. The default is m328, but if you get an error message indicating a mismatch, you can try the other.

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.
