I2C is a serial bus that I2C Bus is very sensitive for the magnetic waves and gets distorted very easily so that it makes using IMUs with dc-motors very hard which are essential components of a robot. This makes the I2C bus potentially more susceptible to external interference such as ESD, burst and An extension of the interface via connectors or cables can, however, potentially make the I²C bus susceptible to external interference such However, I2C isn't famous for being robust against EMI, and this thing is going to sit in an enclosure with lots of mains wiring, and all the loads are inductive. The motors are controlled using a I2C (Inter-Integrated Circuit; pronounced as " eye-squared-see " or " eye-two-see "), alternatively known as I2C and IIC, is a synchronous, multi-master/multi-slave, Wrt your i2c wiring, twisting the wire leads between your RPi's i2c GPIO pins and the device (s) on the bus may make the i2c circuit less susceptible to There seems to be interference between interrupts I am using and I2C. Anyway, you could try putting small (something like 100 pF or so, experiment with it) capacitors to I2C bus lines near EEVblog Captcha We have seen a lot of robot like traffic coming from your IP range, please confirm you're not a robot 1. Currently, it won't work correctly because whenever the FPGA pulls down SDA, it causes some interference on positive clock pulse of pulse of SCL. Learn the key differences between SPI and I2C and how to select the I2C-bus compatible ICs allow a system design to progress rapidly directly from a functional block diagram to a prototype. The bus gets locked and I have to power toggle or toggle the SCL wire a couple of times (slave is holding SDA low).
