2416 Dot Matrix Display Information Board DE-DP016
Chapter1 Overview and Main Feature
2416 Dot Matrix Display Information Boards is manufactured by Sure Electronics. It can be driven by SPI like interface. It an be easy interfaced to any Microcontrollers. It can be widely used in panel meter, big clocks and any other information display usage.
It’s a memory mapping LED display board and driven by HT1632 LED display controller. The device supports 16-gradation LEDs for each outline using PWM control with software instructions. A serial interface is conveniently provided for the command mode and data mode. Only three or four signals are required for the interface between the host controller and the information board. The display can be extended by cascading the information board for wider applications.

Chapter 3 Application Notes
3-1 Display Memory
The static display memory, RAM, is organized into 96×4 bits and stores the displayed data. The contents of the RAM are directly mapped to the contents of LED driver. Data in the RAM can be accessed by the READ, WRITE, and READ-MODIFY-WRITE commands. The following table shows the mapping from the RAM to the LED pattern:
Com15 Com14 Com13 Com12 Addr. Com3 Com2 Com1 Com0 Addr.
Out0 03H 00H Out1 07H 04H Out2 0BH 08H Out3 0FH 0CH Out4 13H 10H Out5 17H 14H Out6 1BH 18H Out7 1FH 1CH Out8 23H 20H Out9 27H 24H Out10 2BH 28H Out11 2FH 2CH Out12 33H 30H Out13 37H 34H Out14 3BH 38H Out15 3FH 3CH Out16 43H 40H Out17 47H 44H Out18 4BH 48H Out19 4FH 4CH Out20 53H 50H Out21 57H 54H Out22 5BH 58H Out23 5FH 5CH D3 D2 D1 D0 Data ….. ….. …..

3-2 Command Format
The command mode consists of a system configuration command, a system frequency selection command, a LED configuration command, and an operating command. The data mode, on the other hand, includes READ, WRITE, and READ-MODIFY-WRITE operations.
The mode of command should be issued before the data or command is transferred. If successive commands have been issued, the command mode ID, namely 1 0 0, can be omitted. While the system is operating in the non-successive command or the non-successive address data mode, the CS pin should be set to “1” and the previous operation mode will be reset also. Once the CS pin returns to “0”, a new operation mode ID should be issued first.
