| description | The utility model belongs to the technical field of bus communication and especially relates to an SPI and I2C bus communication circuit having a simple structure and great communicating effect. The SPI and I2C bus communication circuit comprises capacitance (C1), capacitance (C2), a crystal oscillator, a PIC16F690 chip, or a gate, and an AT24C04 chip. Structural key points of the SPI and I2C bus communication circuit are that the PIC16F690 chip is respectively connected with the capacitance (C1), capacitance (C2), a crystal oscillator, the AT24C04 chip or the gate; or the gate is connected with the AT24C04 chip; the crystal oscillator is connected with the capacitance (C1) and the capacitance (C2); and an interface of the AT24C04 chip and an SCL interface of the AT24C04 chip are respectively connected with a 5V power supply via 10K resistance. |
