Re: RobotC 2.30 for PIC problems
Regarding the firmware not downloading, I tested the download on my end and it seems to work fine.
Is the USB-to-Serial driver installed on that computer? You can get it here: http://www.robotc.net/download/cortex/
Is the Prolific USB-to-Serial option chosen from the ROBOTC Preferences? In ROBOTC, go to View > Preferences > Detailed Preferences. On the Platform Tab, you can manually select the communications port.
