I have several of the old PIC microcontrollers. I wanted to use them for STEM lessons with our feeder elementary and middle school students. I purchased the EASY C Pro software but I’m having problems downloading the software. I get the “To ensure download make sure the power is on and serial cable is connected” message. I have change the cables but I still receive the same message.

You can also use a legacy version of ROBOTC that works only with the PIC-based Brain

This install should include the drivers to connect the Prolific USB to Serial Adapter.

If you are using old programing cables with the Prolific USB chip, and installing RobotC for PIC does not help, have a read through this very old topic.
The prolific drivers have a very checkered history.
