Class TRF7960

java.lang.Object

de.ipcon.tools.TRF7960

public class TRF7960
extends java.lang.Object

Driver for TRF7960 EVM module from Texas Instruments as used in IEI-Devices It consists of a TRF7960 chip connected via i2c to an MSP430 (also from TI), which supplies serial data to an FTDI FT232 chip, which connects to USB. Parts of this driver might be suitable for reuse in other combination involving the TRF7960/7970 chip, as the code is properly separated (aka is using the byte protocol for (most) inner workings).
