But the board showed up under System Information as FT232R USB UART, so I knew the cable was working. To verify you have reset the 8u2 or 16u2 chip: In the Arduino programming environment, check the list of serial ports. I recently purchased an Arduino Mega 2560. I wrote the code to test out the servos and when I tried to upload the program to the arduino the program reported that it could not connect to the board and returned this error: This application has been tested on both Windows and Linux.
Installing the driver fixed it, and now the Arduino shows up as /dev/cu. Windows: use flip to upload the hex file to your board Mac & Linux: from a terminal window, change directories to get into the folder with the firmware.
7 which requires you to select a Port before upload but we don't use Ports for Pro Trinket uploads. Arduino port not showing up windows 10 I prefer to use VS-Code for coding C with Arduino Extension, and this application I use for listening to the logs.
