Description
The HSDL-7001 modulates and demodulates electrical pulses from Hewlett-Packard’s HSDL-1001 Infrared transceiver module and other IrDA-compliant transceivers. The HSDL-7001 can be used with a microcontroller/microprocessor that has a serial communication interface (UART). Prior to communication, the processor selects the transmission baud rate. Serial data is then transmitted or received at the prescribed data rate.
