Tags: axefx | Tonight I put together a test harness on some proto-board,
using 12 micro-switches to test the functions on the foot
controller board. So far so good, all the parts are working
as expected. The next thing to test is the MIDI input and
output. The next revision of the controller PCB with allow
for connecting to the test board via ribbon cable and IDC
plugs. Which will be much neater than soldering the test
harness in.
Also I've installed a contrast pot for the LCD.
Unfortunately I messed up the trace going to the contrast
pin on the LCD in the PCB design. Not to worry, I've cut
that trace on the PCB's using a dremel which leaves it free
to be hooked via a nearby pad to whatever you'll use for
contrast control. The kit instructions will cover that.
After getting all the buttons hooked up tonight, I tried all
the setup menu functions, like factory reset, configuring
the MIDI channel, changing the IA blocks etc. Then I moved
around the presets, and switched some IA blocks on and off.
Everything worked first time... so that's an excellent sign!
