RoboKit 1

Overview

The TDK RoboKit1 is a development board for use primarily with ROS2 and provides a large number of small ground robotics useful sensors including chirp sensors for time of flight (e.g. ultrasonic obstacle detection).

It pairs a 300MHz Cortex-M7 ATSAME70Q21 with an array of TDK sensors and pin headers useful for robotics.

Connections and IOs

The TDK RoboKit Hardware Guide has detailed information about board connections.

System Clock

The SAM E70 MCU is configured to use the 12 MHz external oscillator on the board with the on-chip PLL to generate a 300 MHz system clock.

Serial Port

The ATSAME70Q21 MCU has five UARTs and three USARTs. One of the UARTs is configured for the console and is available as a Virtual COM Port via the USB2 connector.

Programming and Debugging

Flashing the Zephyr project onto SAM E70 MCU requires the OpenOCD tool. Both west flash and west debug commands should correctly work with both USB0 and USB1 connected and the board powered.

Flashing

Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyACM0. For example:
```
$ minicom -D /dev/ttyUSB0 -o
```
The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Connect the TDK RoboKit1 board to your host computer using the USB debug port (USB1), USB2 for a serial console, and remaining micro USB for power. Then build and flash the Hello World application.
```
# From the root of the zephyr repository
west build -b robokit1 samples/hello_world
west flash
```
You should see “Hello World! robokit1” in your terminal.

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b robokit1 samples/hello_world
west debug
