Interface Pin Definitions

Pin Definitions, fully same as demo code:

• #define P_LAT 16
• #define P_A 5
• #define P_B 4
• #define P_C 15
• #define P_D 12
• #define P_E 0
• #define P_OE 2

• pin row_C row_D row_E and row_OE are the extra optional pins for setup, you can install then first
• not all these four pins are needed for some panels
• you remove later to try to release some extra pins which are not necessary

Panel Size

Please double check all the following options

• #define matrix_width 32
• #define matrix_height 16

Software Setup

Panel Drive Methods

• display.begin(4); // 1/4, 1/8, 1/16 and 1/32 row scan. where n={4,8,16,32}

• display.setScanPattern(ZAGGIZ); // Define your scan pattern here

Our panel	matrix_width	matrix_height	Scan	Pattern
32x16	32	16	4	ZAGGIZ
64x64	64	64	32	default LINE

Shield	Panel	Note
Input connector	Input connector	Plug in
Output connector	Output connector	Use cable, if you chain mutiple panels, maybe buy a long cable

Setup Notice

• If power is not stable, use USB power for D1 mini instead
• Turn off IO0 when you are programming D1-mini board
• Some pins may not be used by panel, if you test the pin always go ground, then you can use dip swtich to turn if off and use them. Common pins are C / D / E
