What a weekend to fall ill! I had the whole weekend mapped out to do this, then that, so by Sunday evening I should have assembled one of the prototypes. FAIL! I must have caught a stomach bug or something on Friday, because by Saturday I started feeling really rough. By Sunday evening I could only assembly the 2 x 13 way IDC cable, which connects the two boards together, as can be seen in the Figure above.
The good news so far is that we have been able to assemble a 2 x13 way IDC cable without using any specialist tools and without short circuiting any of the wires, that is by using that well known table vice trick. The figure above should give a better indication of how the signals on the DE0 Nano kit connect to the different parts of the Dilettante board shown. As mentioned in the previous blog there will be no need to snip the digital signal traces on the production boards, as the two sets of signals shall be separated by zero ohm resistor pads.
The second Figure above shows our Arduino sensor, motor and RS232 shields, which we plan to use for testing. When these shields are mounted on the Dilettante board shown, in the previous figure, we begin to see the origins of a powerful robotics system. There are many more ways this board can be used, especially, when used in conjunction with Altera's Nios II processor. In particular we are quite keen to start a new set of tutorials on "Digital Signal Processing using FPGAs". This should involve mounting a multiple DAC Dilettante module on the prototyping area and acquiring their output using the ADC on the DE0 Nano kit. More to follow soon.
