Grid-EYE Evaluation Kit

4.2 Firmware development

For the two modes of operation, independent and Arduino mode, we will explain separately

the development process. We will also give a brief introduction in this section on the

programming of the Bluetooth module built on the evaluation kit.

4.2.1 Development Tools

The following tools are needed when developing application for Grid-EYE Sensor board.

Hardware

1. PC with at least 2 USB interface

2. Micro-USB cables

3. TTL Serial to USB module (only to program Bluetooth module PAN 1740)

4. J-Link

Software

Users need to install the following software according to the target they develop:
