VexU wiring non-Vex sensors

[MTO967]

Hi, starting first year in VexU and since we can use almost any sensor, I was wondering if someone can give me a rundown on wiring to the V5 brain or a pinout diagram for the smart ports to try sending signals to the brain.

Thanks for any help you can provide

V5 and crossover cables?

Excellent question. To my best knowledge, the pinout is as follows: RS-485 A RS-485 B Power GND So if you manage to get a RJ11 crossover cable somewhere (or actually made one yourself, that’s much more likely occurence) and use it, you should still be good - as in, it won’t work, but nothing will burn. RS-485 inputs need to be very resilient and high-enough input impedance anyway, so power into one of them is no big deal (the chips I have seen used survive ±70V, besides 16kV static discharg…

Use V5 Smart Port as Generic Serial Device [PROS]

We are trying to figure out how to use a V5 port as a generic serial port in PROS, and have had little success. As far as we can see, the main control functions PROS provides are serctl(), and registry_bind_port(). We can see how to bind the port with the second function, but are not sure how to go about reading the serial data from the port. In the vex api there is a vexGenericSerialRecieve() function, where you pass in the port, and a buffer for the data. However, we cannot find an equivale…

@holbrook thanks for the response.
Correct me if I am wrong, but it looks like I can use a ttl to RS485 module to communicate directly to the smart ports?
