LCD Driver datasheet The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of SPFD54126A adopts OP-AMP structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power consumption.

所谓短信猫，其实是一种工业级级GSM MODEM，通过串口与计算机连接，可以通过AT 指令控制进行短信收发的设备。国内目前应用较多的短信猫，都是以SIEMENS 或WAVECOM 模块为核心组装而成的，与普通手机相比更为稳定高效。-The so-called SMS cat is a kind of industrial-level GSM MODEM, connected through the serial port and the computer can be carried out through the AT commands to control the device to send and receive text messages. At present the application of the domestic cat more messages are to WAVECOM module SIEMENS or assembled at the core, and more stable compared to the ordinary high-performance mobile phones.
