NyBoard Preparation

For Nyboard products (Nybble, Bittle), there are two ways to upload the firmware (Mind+ mode), which supports the Mind+ extension library:

• Using the Petoi Desktop App

  

  • If you just downloaded a new version of this Desktop App. You should click the Upgrade the Firmware button. You can select 'N' to preserve the calibration values.

  • If you have upgraded the firmware at least once after a new download, You can click the Update the Mode Only button. It's faster to only switch the modes without refreshing the parameters.

• Using the Arduino IDE Please download the latest code from GitHub. Follow the steps for uploading. Set up the configuration mode and activate this line of code in OpenCat.ino #define MAIN_SKETCH

  #define GROVE_SERIAL_PASS_THROUGH

  Then, upload the major functionalities sketch and power on the robot. Use the data cable and USB uploader to connect with the computer or the Bluetooth module and complete the pairing.

Note that the gyroscope function is turned off with the Mind+ mode on NyBoard to save memory space. The robot won't be able to self-balance and auto-recover.

If you don't use the "Read or Write analog/digital pin" function block, you can upload the Standard mode sketch for Bittle / Nybble and use the Mind+ extension library. Note:

When the robot is in Mind+ mode, the gyroscope function is turned off, and the robot cannot balance or auto-recover.

After uploading the firmware, plug in the battery to the NyBoard, install it to the chassis and long-press the battery button to power on the robot.

Connect method

• Wired connection: The kit includes a USB Adapter and USB data cable connecting the robot's mainboard to the computer.

• Wireless connection(Bluetooth)： The kit includes a Bluetooth module connecting the robot's mainboard to the computer.
