Load Code on the HMI

To do this I am going to use an SD card to flash the HMI code.

Go to File->TFT File Output, select where you want to output the file to and click the ouput button. Open up the folder that the TFT file was put and copy this file onto your SD card. Make sure that it is the only file that is on the SD card.

Put the sd card into the microSD card slot on the HMI and turn on power. It will start flashing the HMI. Once it is done flashing remoce the microSD card and cycle the power. The switches should appear on your screen.

Now that we have the HMI code done and flashed lets jump over to the Arduino IDE and write some code to actually switch the relays on and off.
