ISP (In-System Programming)

The Evalu8r is capable of supporting the In-System Programming (ISP) functionality available

on the Atmel 89S and 90S(AVR) microcontroller derivatives. To facilitate ISP it is necessary to

connect an Equinox ‘Micro-ISP’ or Activ8r programmer to the ISP header (Con 8) on the

module as detailed in the figure below. Alternatively the ISP connection on the Equinox

Activ8r may be used to connect to the Evalu8r.

Prog LED

The Serial programmer will illuminate the ‘PROG’ LED (LED 9) on the Evalu8r during

programming.

ISP LED’s

The MOSI/MISO/SCK lines from the serial programmer are shared with LED 5/6/7. During

serial programming these LED’s will flicker on and off. If any problems are encountered

during programming it is possible to disconnect all 8 LED’s by removing the resistor SIL pack

(SL1).

Piezo Sounder

The Evalu8r module is shipped with the Piezo Sounder enabled by default. This will make a

noise during programming and is useful as an audible indication that ISP is working. To

disable the sounder, simply remove link 6.
