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_”.
