4.15 Inter IC Bus (I C)

4.14.1 CAN Analyzer

To understand the data transmitted on the CAN
you need a CAN Analyzer. I used the PCAN-
USB from www.peak-system.com. This CAN in-
terface allows you to see the messages transmit-
ted on the CAN bus.

STM32F103RB have two I C bus interfaces which can operate in multimaster and slave modes.
They can support standard and fast modes. They support dual slave addressing (7-bit only) and
both 7/10-bit addressing in master mode. A hardware CRC generation/verification is embedded.
They can be served by DMA and they support SM Bus 2.0/PM Bus.
Introduction
3
The I C interface is a serial interface with three wires.
The clock on the one directional wire SLC is generated by the master with a fix frequency. This
line is stable (normally high) when no data are transmitted on th data line. The second wire SDA
is bi directional and used for the data communication between the master and the slave
The wiring is according to Figure 4.17.

IIC, I C (Inter IC Bus) were developed and registered by Phillips and saved as a trademark. Atmel uses the name
TWI.

The slave is controlled by the master.
