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.
