1 . General RF50 Demo V. 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.. Board characters 4 keys, UP key, DOWN key, ENTER key and key. key is used to reset MCU, the other keys is used to parameter setup and TX control. A piece of LCD is used to display the parameters and result of test. 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. A/D function PWR DR FDEV BW power SW LEDTX LEDRX KEY VR0 As top displaying, rotate the variable resistor(vr0)to adjust the input voltage of A/D port, the LCD display s A/D voltage result is change from 0 to 00mV. 4. RTC function As top displaying, can display and setup the current time, using 4 hour mode. 5. Compare function As top displaying, rotate the variable resistor(vr0)to adjust the input voltage of A/D port, when the input voltage higher than 650mV (VDD/) the LCD display CP+, when lower than 650mV(VDD/) the LCD display CP_.

2 6. UART function Can transmit testing information, error information and received RF data to UART port. 7. Timer function In demo code have a ms timer. 8. Interrupt function This function is used in any other functions testing. 9. Clock source function RF50 Demo V. Can select the RF50 working with internal OSC or external OSC. When select external OSC, the jumper J04 and J05 must connect to left.. 0. RF transceiver function Must connect jumper J0. Working in normal mode, when press UP DOWN ENTER key on one DEMO board it will transmit RF data, the TX LED will flash once. When receive back data the RX LED will also flash once. The LCD display the transmited RF data and the received back data (every have two bytes, the first byte is key code, the second byte is key pressed times), also display the received RF signal strength. The LCD display as follows: TX data RX data Tel: Fax: sales@hoperf.com

3 RF50 Demo V. When press UP DOWN ENTER key on the other DEMO board to transmit RF data., this DEMO board s RX LED will flash once if received data, then transmit the received data, the TX LED will flash once at the time. The LCD display the received data (two bytes the first byte is key code, the second byte is key pressed times), also display the received RF signal strength. The LCD display as follows: Tel: Fax: sales@hoperf.com

4 RF50 Demo V.. Parameter setup When press ENTER key s on the board, it will work in setup mode and all setup items will flash. Then short press ENTER key, the board will enter next setup item by the order that frequence, MCU clock, hour, minute, second, power, data rate, Fdev, band width. When finish setup the band width item, the board will exit the setup mode. In setup mode, when long press the ENTER key or no press key in 0s the board will also exit the setup mode. When in frequence setup mode, the fequence item flash continue, pressing UP key or DOWN key can select which frequence from one of the MHz. When in MCU clock setup mode, the clock item flash continue, pressing UP key or DOWN key can select which clock from one of the Int Ext. When in hour setup mode, the hour item flash continue, pressing UP key or DOWN key can select which hour from 0 to at present. When in minute setup mode, the minute item flash continue, pressing UP key or DOWN key can select which minute from 0 to 59 at present. When in second setup mode, the second item flash continue, pressing UP key or DOWN key can select which second from 0 to 59 at present. When in power setup mode, the power item flash continue, pressing UP key or DOWN key can select which grade of TX power from 0 to 7. When in data rate setup mode, the DR item flash continue, pressing UP key or DOWN key can select which data rate of transceiving from one of the Kbps. When in Fdev setup mode, the Fdev item flash continue, pressing UP key or DOWN key can select which Fdev of TX from one of the KHz. When in band width setup mode, the band width item flash continue, pressing UP key or DOWN key can select which band width of RX from one of the KHz. Tel: Fax: sales@hoperf.com 4
