+AVR ISP / Atmel ATmega88
+-------------------------------------------------------------------------------
+
+This is a set of example captures of the AVR in-system programming (ISP)
+protocol.
+
+The device used for ISP was a USBprog with AVRISP mkII compatible firmware.
+
+The target was a board with an Atmel ATmega88 chip.
+
+The PC software used for controlling the programmer was avrdude 5.11.1.
