PIC16F876 Control of 8 Servos Motor 5 Analog Channels I2C bus
Microcontroller PIC16F876 4Mhz Controlled by the I2C slave module and analog servos technical report describes the design, both from the electronic point of view, as a computer control board for I2C bus 8 standard radio control servos, and 5 analog inputs (analog / digital conversion). The main characteristics of the module are presented as follows:
Acts as Slave by allowing you to select the address dip switches used in the I2C network.
It can be set by both the desired I2C bus position of each servo, as the direction of rotation and the Offset.
Can be read by the I2C bus corresponding to any of the 5 analog inputs of the digital value available (8 bits).
