The fcb1010 has a numerical display made of 3 digits. It also utilizes a series of LEDs to give more info about its current state. At best, this is an arcane way of doing things, like trying to program a computer using a old rotary telephone. At its worst, it does make you hate the FCB1010.
I will be writing a Mac/PC/Linux interface as I go along, but certain functions are better accomplished on the device itself (very few!)
During prototyping, I will be using an alphanumeric display, made of 2 lines by 16 characters each. I’m debating whether to add a numerical display, either a simple one similar to the one used now on the FCB1010, or a useful one like the one below. Adding the display is trivial, but expensive.
This display, form an old Digitech GNX3000, is ideal: 8 alpha-numeric 14-segments digits and 2 contrasting numerical digits. The entire display can be run from a single chip… but that chip costs 20$, in quantities of 25! Add 15$ for the set of digits…
Driving a 3 digit display, directly from the Arduino using a serial interface and one digital pin can be done for 13$.
