Use PORTB RB/ as a switch to select the frequencies. If RB/ = 0 (Low), the Frequency 1 square wave will be generated and if RB7 - 1 (High), the Frequency 2 square wave will be generated. When one square wave is generated, the other output pin stays at logic O (low). Calculate and program the Timero count values to achieve frequencies as close as possible to the target values. Use a crystal oscillator frequency fosc = 20 MHz. Examine the PORTS output pins using the MPLAB Logic Analyzer and check the actual times with the Stopwatch. Use the Toggle Stimulus to change the value of PORTB RB/ Student Frequency Frequency ID ends with RB7 = = 0 RB/ = = 1 0-2 300Hz 450Hz 500Hz 650Hz 5 7 550HZ 70OHz 8-9 450HE GOOHE L' Upa ENG 05:03
