TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
Huawei EM770w is a state of the art 3G/GPS/HSPA Mini PCI Express module with worldwide support for UMTS and GSM/GPRS.
The module has support for the Mini PCI Express HW Reset Pin (#PERST, pin 22) which makes it perfect for M2M and other embedded applications.
The module also includes an integrated GPS which makes it suitable for location-based applications as well.
This guide instructs the kernel driver integration development for Huawei Modules based on Embedded Linux & Android operating system. It is intended for the driver developers of the products based on Embedded Linux & Android OS.
The purpose of this document is to describe some hardware specification which is useful to develop a product with HUAWEI EM770W module supporting PCM (Pulse- Coded Modulation). This document is intended for HUAWEI customers who are integrators and about to implement their applications by using our module.
The HUAWEI EM770W module supports the PCM, which can be used for the module to transmit and receive digital audio data. Linear and μ-law codecs are supported. The HUAWEI EM770W module uses the PCM interface as part of the audio front end; it easily allows for an external codec to be used instead of the internal codec. As an example, through the PCM you could connect a HUAWEI Module to a Bluetooth device.
The HUAWEI EM770W module has one PCM port. Please refer to the Hardware Guide of the module that you are using to know the PIN number of the PCM ports.
