I have just received a number of VEX LCD diplays. They look great and appear to be well supported by RobotC 2.01. All is not so good when I try to connect them to the VEX controller. No cables are supplied and I cant see how to attach the PWM cables to the controller. There is nothing in the documentation so I am assuming it all should be obvious. Help !
**You will need to provide your own PWM cables. Here are the instructions taken directly from the included documentation (also available here: https://vexforum.com/wiki/images/b/b3/VEX-LCD-Display.pdf):
There are two interconnect ports on the side of the LCD module. The two interconnect ports are labeled RX and TX. The RX and TX ports are labeled with respect to the device that connects to the LCD Display Module.
Example: Data is flowing out of the RX port on the LCD Display Module; therefore, the RX
(output) port on the LCD Display Module should connect to the RX (input) port on the VEX PIC Microcontroller. Likewise, the TX (input) port on the LCD Display Module should connect to the TX port (output) on the VEX PIC Microcontroller.
Use standard VEX Keyed PWM Cables for connecting the LCD Display Module to the VEX PIC Microcontroller. Use the VEX Serial Y-Cable for connecting the LCD Display Module to the VEX Cortex Microcontroller. The Y section of the Serial Y-Cable with the Yellow wire connects to the RX port and the Y section with the White wire connects to the TX port on the LCD Module.**
Thanks Sean. It all became obvious when I put my glasses on and actually read the lettering on the Analog/Digital moulding. The whole thing works brilliantly and within 15 minutes I had a display showing sonar and line tracker readings as well as using the buttons to turn motors on and off. Cool.
