Recent Lanshuo planning Chongming Island, Shanghai Science and Technology Museum to build indoor giant curved screen and high-definition LED screen LED waterlines are now completed, the curved screen a total area of 120 square meters. Below the screen body using the latest oled display module shaped screen, showing the effect is like water, like, realistic effect. The implementation of the project, Lanshuo technician breakthrough in the shortest possible time multi-channel LED display technical difficulties - the courage to challenge, less than 15 working Lcd display modules days to complete the project, which is the Shanghai World Expo in Shanghai, following Lanshuo Bamboo and Rattan after another major museum projects in Shanghai. This marks the Shanghai Urban Planning Lanshuo Hall for each project tailored ripe. Currently, Shanghai Lanshuo now covers the oled display module northeastern provinces, the Northwest region, as well as central and eastern regions. Including the Shanghai Urban Planning Serial display modules Exhibition Hall Chongming, Shanghai North Industrial Park Planning Exhibition Hall, Fujian Longyan Urban Planning Exhibition Hall, Wenling, Zhejiang Urban Planning Exhibition Hall, Jiangxi Shangrao Urban Planning Exhibition Hall, Zhuzhou, Hunan Urban Planning Exhibition Hall and other Planning Exhibition Hall ! Shanghai blue-seok as a mature LED electronic display manufacturers, not only has advanced equipment and a wide variety of LED display products, designed to provide customers with a more suitable environment LED display.

oled graphic display pin functions and command system
Module pin functions as listed in Table 1. Instruction modules and LCD driver compatible controller, a total of seven instructions. Not described in detail here, as listed in Table 2 only instruction list. Among them, the state is set to show the first two instructions, the rest of the class to read and write commands. Display Module with Lcd display module Cygnal microcontroller hardware interface design
VGS12864E interface connection in two ways: one is the direct access mode, the other is indirect access. Either way, you want to access the module must first read the contents of the status register to determine the "busy" flag can be accessed when not busy. Direct access method is a module interface as a memory or I / O devices directly linked to the MCU bus, MCU to access memory or I / O device mode the module operation. Indirect access MCU module is operated via software simulation control timing. Here is indirect access interface design Cygnal C8051F020 MCU and VGS12864E of.
Cygnal C8051F020 is an American company launched a mixed-signal SoC-based 8-bit microcontroller, a highly Serial display modules integrated mixed-signal system-on-chip. It has a 100-pin TQFP package, low power supply voltage of 2.7 ~ 3.3 V, all I / O, RST, JTAG pins are resistant to 5 V voltage; has high speed pipelined 8051-compatible CIP51 core structure (up to 25 MIPS). The MCU has a total of 64 P0 ~ P7 purpose I / O ports, each port pin can be configured as push-pull output or open-drain output. For VGS12864E, due to its operating voltage is 5 V, and C8051F020 operating voltage is 3.3 V, so the output C8051F020 better able to drive 5 V input OLED, the system requires additional configuration. In addition to the corresponding output port is set to "open drain", but also in the circuit will be connected to each port through a pull-up resistor on a 5 V power supply, so you can ensure C8051F020 logic "1" output can be raised to 5 V. The interface circuit shown in Figure 2.
