9.0 EQ-CALCON Module
9.1 Overview
The EQ-CALCON Module is a special plug-in I/O Connector Module for the PPM3-MK2 programmer
which is used to facilitate very accurate calibration of the Internal Oscillator of an Atmel ATmega or
ATtiny AVR microcontroller. The module features an on-board high accuracy 32kHz Oscillator
Module which can be connected to the target AVR microcontroller MOSI pin during the Oscillator
Calibration Procedure as described in the Atmel Application Note 'AVR053: Calibration of the Internal
Oscillator'.
The EQ-CALCON Module is simply an I/O Connection Module with an on-board 32kHz oscillator. The
target microcontroller SPI or JTAG signal lines connect to the module headers or clip-in connectors.
The 32kHz oscillator is then switched onto the target device MOSI pin under control of the
Programming Project running in the programmer. The EQ-CALCON Module must be used in
conjunction with a PPM3-MK2 programmer in order to operate.
