I2C Protocol Analyzer
EasyI2C
-
It's simple to find an I2C-style bus within arm's reach. Every computer, monitor, television and cell phone has it. Most microcontrollers directly support this protocol as well. Even so, the I2C protocol has many subtle nuances that are hard to grasp and easily forgotten. EasyI2C (TM) helps you to figure out exactly what is happening, without having to examine huge waveform trace capture files or set up complex tests.

USB-8451, 250 kHz I2C, 12 MHz SPI I2C/SPI Interface Device
779553-50
Interface Module
The NI USB‑8451 is a master interface for connecting to and communicating with inter-integrated circuit (I2C), System Management Bus (SMBus), and serial peripheral interface (SPI) devices. With plug‑and‑play USB connectivity, the USB‑8451 is a portable solution to communicate with consumer electronics and integrated circuits. It also includes eight general-purpose digital I/O lines for a variety of applications, such as configuring the address of I2C devices or toggling LEDs. The USB‑8451 can be physically located more closely to I2C/SPI devices than PCI interfaces, reducing I2C bus length and minimizing noise problems. Additionally, the interface provides +5 V and GND to power circuits with no external power supply.

As a result, the MCP9600 can read both the ambient temperature and the temperature of whatever you're trying to measure! The MCP9600 can do both with a resolution of 0.0625°C, and an accuracy of ±1.5°C (worst-case). The MCP9600 Thermocouple Amplifier is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!
