Ch Arduino

Q: My Arduino can get connected but not able to respond any commands I sent through both ChDuino and Ch program?
A: Every board needs a factory-supplied firmware to work with Ch Arduino package. You can start the Firmware Uploader from the “Tools” at the menu bar of ChDuino. The Firmware Uploader starts in a separate window. Click “Scan” button on the top of the window. The list below will itemize all Arduino boards connected through USB cables. Select the desired board from the list and click “Upload Firmware” button at the bottom of the window. The uploading starts automatically and the progress bar in the window shows the percentage done of the process. Once it is done, you can close the Firmware Uploading and start using Ch Arduino package with the board.

Q: Why do I keep getting the message “scan complete, no devices found” when tying to connect my board to Ch Arduino?
A: First, please check that your set-up is correct and that you are following the right procedure, as described in this video tutorial.
If you recently installed C-STEM Studio MSI files or haven’t used Ch Arduino on this computer before, you may need to install the Arduino drivers. Please have IT Staff log in and navigate to the “Registered Users Subsite” on the top right of our webpage. From there, click on “Downloads for IT Staff” and download C-STEM Arduino Driver.

Q: What can I do if my LED won’t work?
A: Try using a different LED or wires.
