How many controller ports have you used?

VEX V5 General Discussion General Forum

A comment on the New Platform thread made me wonder:

What is the largest total number of ports you’ve ever used on the Vex controller?

The Vex Microcontroller has a total of 32 ports:
[LIST]
*]8 PWM
*]6 Interrupt
*]16 Analog/GPIO
*]2 Serial (TX/RX)
[/LIST]
(I’m not counting the back-panel connectors)

My personal best is 17:
[LIST]
*]5 PWM
*]2 Interrupt (would have been 4 if I used quadrature encoders)
*]3 Analog
*]7 GPIO
*]0 Serial
[/LIST]

9 if you don’t count y connects, 11 if you do, 10 motors and 1 jumper clip

I do think that vex could use a few more motor imputs, but there not really nesessary. The Vex MicroControler is very nice as it is.

Fact of the day: There is 4 or 5 (can’t remember which) ports right above the motor inputs that are not used and are covered. They are just not used so the interrupts and motor ports could be separated.

I just assumed that area was either not wired, or was hooked to diagnostic lines (like JTAG). Are they wired to anything that might be of use to an end-user?

Oh, and Technic-R-C: What were you doing that needed more than 32 ports? We need details! :wink:

At one time our robot this year used every single port except for the TX and RX ports. Thats why we had to use pot to change auto modes.
