Test2:
measure with a multimeter U4 pins 5, 6, 12 and 13, they should be
going ON(+5V) and OFF(0V) every 2 seconds:
•
Test3:
While pushing the tap footswitch (connected to J12), measure again U4
pins 5, 6, 12 and 13 they should be going ON(+5V) and OFF(0V) every 1 second:

Test4:
When in debugging mode, the LEDs should light in loop:
GREEN - RED – OFF
o
If you activate the pedal pushing the 3PDT footswitch SW1, the LEDs will
do the loop at double the speed.
NOTE:
Once you finish, disconnect the R24 DEBUG wire, so the pedal can do to
normal mode.
STEP 9 – Check the Pedal:
At this point, you are ready to use the pedal. It is designed to be checked before
being boxed, so makes everything easier to fix and mod.
if you have any question about the
functionality. At this point, you can also easily reprogram the microcontroller if you
want to experiment with sounds.
Note: The board is upside down, so the amp and guitar connect to opposite sides (see below):
