HopeRF RF50 Demo Manual

1. General

RF50 demo board is developed for RF50 chip (which is integrated MCU and RF circuit in single chip) to
demonstrating function, testing distance and debugging software.

2. Board characters

4 keys, UP key, DOWN key, ENTER key and RST key. RST key is used to reset MCU, the other 3 keys is
used to parameter setup and TX control. A piece of LCD is used to display the parameters and result of test.
3 indication LED, the first is power, the second is TX, the third is RX..
Power on, LCD display as follows:
RSSI RTC FREQ CLK AD compare RF50 antenna test port ISP UART
PWR DR FDEV BW power SW LEDTX LEDRX KEY VR101

3. A/D function

As top displaying, rotate the variable resistor（VR101）to adjust the input voltage of A/D port, the LCD
display 's A/D voltage result is change from 0 to 3300mV.

4. RTC function

As top displaying, can display and setup the current time, using 24 hour mode.

5. Compare function

As top displaying, rotate the variable resistor（VR101）to adjust the input voltage of A/D port, when the
input voltage higher than 1650mV (VDD/2) the LCD display "CP+", when lower than 1650mV(VDD/2) the
LCD display "CP_".
