I2C Decoder
The I2C Decoder displays the data being sent or received by I2C-compatible devices (I2C command is
supported only by the BS2p and BS2pe). To use this feature, you must first identify the BS2p24’s I/O
connections that are connected to the I2C-compatible chip’s SCL and SDA pins.
For example, the following is an example of transmitting a “write” command to an I2C device connected
to pins 0 and 1, followed by an address of “5” and a number of “100”. It is important to have an I2C
device connected to the BASIC Stamp in order to receive acknowledgement.
