If you happen to have a Linux system with at least 4 hardware GPIOs
available (like almost all embedded Linux boards) you can do without
any additional hardware - just connect them to the SDO, SDI, RESET
and SCK pins on the AVR and use the linuxgpio programmer type. It bitbangs
available (like almost all embedded Linux boards) you can do without any
additional hardware - just connect them to the SDO, SDI, RESET and SCK
pins of the AVR's SPI interface and use the linuxgpio programmer
type. Older boards might use the labels MOSI for SDO and MISO for SDI. It bitbangs
the lines using the Linux sysfs GPIO interface. Of course, care should
be taken about voltage level compatibility. Also, although not strictly
required, it is strongly advisable to protect the GPIO pins from
