Upload Firmware

Connect to the mainboard.

Some USB cables are just for charging and do not have data transfer capability. It's better to use the original data cable in the kit to make the uploading successful.

NyBoard

When you use a USB uploader to upload the firmware for the NyBoard, if there is no serial port in the port list of Device Manager.

Nybble

Bittle

Please download and install the USB driver:

• Mac: http://www.wch-ic.com/download/CH341SER_MAC_ZIP.html

• Windows: http://www.wch-ic.com/downloads/CH341SER_EXE.html

• Linux: http://www.wch-ic.com/downloads/CH341SER_LINUX_ZIP.html

BiBoard

When you use a USB type-C data cable to upload the firmware for the BiBoard, if there is no serial port in the port list of Device Manager.

Bittle X

Please download and install the USB driver:

CP210x USB to UART Bridge VCP Drivers - Silicon Labs

For more details, please refer to the BiBoard USB Driver to access the serial port.

Upload the firmware

There are two methods to Upload the firmware to the robot:

• The simplest method is to use the Petoi Desktop App. No programming is involved. You can play with some preset modes.

• If you have some programming experience, you can use the Arduino IDE. You will be able to modify the open-source codes for your new projects.

  • If you are using NyBoard, please refer to Upload Sketch for NyBoard.

  • If you are using BiBoard, please refer to Upload Sketch for BiBoard.

If you have a NyBoard(with Bittle and Nybble), we highly recommend using the green USB programmer to upload the firmware. The Bluetooth dongle is not as stable and may cause the mainboard's bootloader to crash if interrupted in the middle.

For BiBoard(with Bittile X), the USB/Bluetooth connections are built on the board already.
