HOW DOES IT WORK?
IrDA 4 Click is based on the TFBS4650, an infrared transceiver from Vishay Semiconductors. It is a low-power consumption device with a standard IrDA link distance of 1m. At this distance, the transceiver supports data rates up to 115kbit/s per the IrDA standard. The MCP2120 encodes an asynchronous serial data stream, converting each data bit to the corresponding Infrared (IR) formatted pulse, with received IR pulses decoded back into the corresponding UART formatted serial data. The combination of the MCP2120 and TFBS4650 results in fast and stable infrared data communication covering the full IrDA range in distance and speed.
To communicate with the host MCU, IrDA 4 Click uses MCP2120 and its onboard clock generator for the fastest possible UART performance of 115.200 bps, so it does not need an additional clock signal to be generated by the MCU. The RST pin of the mikroBUS™ socket can reset the MCP2120, while the SD pin with an active HIGH logic state can be used to put the TFBS4650 into a Shutdown state.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL V1 jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Apart from the V1 jumper, there are two more: V2 and V3. The V2 jumper serves as the main power supply of the TFBS4650, while the V3 jumper allows you to set the voltage specifically for its IRED anode. Each of these positions can be selected independently, allowing you the flexibility to choose the configuration that best suits your requirements. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
