The operational amplifier in the figure is powered by a single power supply, with a resistor of 10K and a capacitor of 10nF. When R1C1=R2C2=R3C3, the frequency generated by the circuit is 1/2*Pi*R*C=1
I am going to drive the RD117 module, which uses I2C for communication. I originally planned to use firmware I2C, but the development board has directly connected I2C to AT24C02, which is not convenie
