progress. After operation finishes successfully the GREEN LED will blink
for a while, otherwise on error the RED LED will blink for a while. After that
the programmer will enter normal state where only the GREEN LED is on
constantly.
The right LED of AVR-ISP500-ISO is a bi-color LED which shows the last
autonomous operation status for indefinite time. Again, RED is for error,
GREEN is for success, off if no status is available due to ongoing operation.
This LED is also off after power up to signal that no autonomous operation
has taken place so far. This LED is helpful for long autonomous
programming sessions where user is not required to look for the end of a
programming session.
If programmer button is pressed and held for more than 1 second but less
then 5 seconds, it will show the current log status. A blinking GREEN
indicates a valid log, and blinking RED indicates invalid/erased log.
The formal definition of the programmer states is given below.
In case of autonomous operation error, the RED LED will blink for a while.
The number of flashes indicates the error that caused the failure. Error
codes are given in the table below.
