The I²C bus and the SMBus™ are popular 2-wire buses that are essentially compatible with each other. Normally devices, both masters and slaves, are freely interchangeable between both buses. Both ...

[Inderpreet’s] chosen LCD used an I2C interface, which was new to him. Rather than shy away, [Inderpreet] grabbed his Bus Pirate and dove in! I2C or Inter-Integrated Circuit serial interfaces ...

but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful first step in debugging an I2C system.

There are many more devices available. I2C is a bus. That means there can be multiple I2C devices connected to a single port on the Photon/Electron. There are some limitations to this, which we'll go ...

I have an issue with the BQ24271 causing a I2C bus collision. My bus diagram is shown below. There are 6 devices which sit on the I2C bus running at 100kHz with a PIC uC as the master. There are two ...

Currently configuring components that talk to peripherals on an I2C bus involves providing the same SDA and SDC pins and clock speeds again and again. Everyone's code ends up duplicating the same ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

When I run a check for devices on I2C-1 I get errors in u-boot: U-Boot# i2c dev 1 Setting bus to 1 U-Boot# i2c probe Valid chip addresses:i2c_probe: pads on bus 1 probably not configured (status=0x10) ...

The MI2Cv2 provides an interface between a microprocessor and an I2C bus that conforms to V2.1 of the I2C bus specification. It can be programmed to operate as either a master or a slave device and ...
