Info

All buttons and DIP switches are active low, i.e. when pressed or in the “ON” position they provide a logic level of 0, and when not pressed or in the “OFF” position they provide a logic level of 1.

Each of these switches is connected to an individual FPGA-pin. Furthermore, all switches do not include an anti-dender circuit and the seven buttons are connected to clock-inputs of the FPGA.

Serial Infrared Transceiver SIR TFBS4711¶

The datasheet of this SIR can be found here: tfbs4711. The control pins of this IRDA which are connected to the FPGA are listed in the table below. An example tcl-file that can be used with Quartus can be found here: irda.tcl.
