How to use with Arduino

1: Run Arduino Demo in SPI model

When we directly connected the SPI display module without the on-board level conversion module to the Arduino, we found that it could not run at all. This is because the SPI module's pin can only input a 3.3V high level, while the Arduino output has a high level of 5V. To run successfully, there are two Method: short circuit method and external level conversion module method. The short-circuit method has the advantages of simple operation, short wiring, and no need for external devices. The disadvantage is that the module generates a large amount of heat during operation.Will affect the life of the module. The external level conversion module method is a normal operation, and the advantage is that the module generatesless heat and runs stably during operation, and the disadvantage is that the operation is slightly complicated. (An external level shifting module is required) to increase the cost (additional level conversion module is required). In summary, it is recommended to use the external level shifting module method.

Step 1: Short-Circuit Method
The short-circuit method is to short the J1 component position (shown below) with solder on the back of the module.After shorting, the runtime module VCC The pin must be connected to a 5V power supply (not connected to 3.3V).


Step 2: External Level Conversion Module Method
The so-called external level conversion module method is to connect the Arduino and the display module through an external level conversion module, so that The 5V high level of the Arduino output is converted to 3.3V by the level conversion module and then input to the display module. As shown below:


Step 3: The TF card is connected to the PC and formatted using the SDFormatter software.
Step 4Open the Win32DiskImager software, select the system image prepared in step 1, and click write to burn the system image.
Step 5:After the programming is completed, open the config.txt file in the root directory of the TF card, and add the following code at the end of "config.txt" to save and safely eject the TF card.
