The Transponder Demo Board has a Programming Connector (J1) for In-Circuit Serial
Programming™ (ICSP™). See
transmitter can therefore be re-programmed using the PICkit
removing the microcontroller from the board.

When the Transponder Demo Board is powered on, the PIC16F636 (MCU) programs
the configuration registers of the MCP2030 and also the configuration register of the
MCP3421 (ADC). After these set-up procedures, the MCU enters a low-power sleep
mode while the MCP2030 is looking for a valid LF command. The MCU is waken-up by
the demodulated output from the MCP2030 or button switch event. If the MCU receives
a valid demodulated data from the MCP2030, then it transmits its 32 bit transponder ID
followed by the 16 bit received signal strength indicator (RSSI) data. If the MCU is
waken-up by a switch event (SW3 and SW4), it transmits the corresponding switch
event data. The data is always attached to the header (See
der ID is set to “04234567” and programmed in the EEPROM. The RSSI data is pro-
portional to the LF signal strength. Therefore, the RSSI data increases as the
Transponder Demo Board comes closer to the Base Station Demo Board. The Tran-
sponder Demo Board transmits each byte LSB first and also transmits a parity bit at
end of each byte. See
