* @brief File for factory programming Inkplate6 COLOR
6+
*
7+
* @note Tests will also be done, to pass all tests:
8+
* - Edit the WiFi information in test.cpp.
9+
* - Connect a slave device via EasyC on address 0x30 (you may change this in test.cpp also).
10+
* In the InkplateEasyCTester folder, you can find the code for uploading to Dasduino Core
11+
* or Dasduino ConnectPlus to convert Dasduino to an I2C slave device for testing an easyC connector
12+
* if you don't have a device with address 0x30.
13+
* - Insert a formatted microSD card (doesn't have to be empty)
14+
* - Press wake button to finish testing
15+
* Output of the tests will be done via Serial due to slow screen refresh rate.
