AVT2899 A

The I2C bus is very popular - its advantages make it used in a variety of electronic devices (clocks, thermometers, sound and image processors, etc.) For many electronic constructors it is important to diagnose possible transmission problems efficiently. Unfortunately, the programming methods are unreliable. This problem is particularly important in prototype systems, constructed from 'zero'. That is why an external I2C analyzer is needed, which we present. The layout is quite simple and thanks to it very cheap. Built from popular components, it is possible to make even by novice electronics. The reception is carried out on the curriculum and the results are sent to the computer.

The device is especially recommended for constructors-electronics using the I2C bus

Selected parameters:

• analysis of rails with speeds of 0-600kHz (900kHz)
• input voltages <30V
• automatic detection of Start, Stop, data transmission and Ack / Nack confirmation signals
• connection with a computer via RS232
• operating mode indication - LED diodes
• power supply - 12Vdc
• dimensions of the tile 64x47mm
• a printed circuit board and documentation in the set
