Circuit board 90% complete
October 13, 2008
So this is the first pic when it was about 50% complete, with the picaxe adapter mounted. The jumpers next to the adapter are used to select which picaxe to use when programming.
The next image is with the pwm circuit that I had worked on, mounted on the main circuit board.
The 08m(empty socket at bottom right) controls the motor pwm control circuit.
The 14m(top center) sends signals to the motor pwm control circuit.
The 08m (empty socket top left) controls ir comm, this is a work in progress....
The motor controller(empter socket next to the power interface) is connected to the pwm circuit.
The motor controller is the 754410(L293D replacement) .
The next iteration with all of the com channels between the picaxes set as well as the programming i/o set.
I tested this tonight and all three picaxes were detected. Next I'll be fine tuning the communications side and add some tests.
Anyway, here is the backside....lots of soldering hours were put into this...
...and the frontside again, updated version.
The programs for each chip are being debugged at the moment so the next part is to fine tuning and streamline. Should be the fun part.
