I²C
I²Cstands Inter-Integrated Circuit and is a serial data bus developed by Phillips. The bus designed as a master-
slave bus requires 2 signal lines:
l SCL (Serial Clock Line)
l SDA (Serial Data Line)
The electrical specification provides that both lines are terminated with a pull-up resistor to VDD, since all devices
connected to the bus have open-collector outputs. The bus clock is always specified by the master, which deter-
mines the entire communication:
After the start condition, the slave address always follows in the transmission protocol. Bit 0 is the so-called R/W
bit and determines whether the slave should read (1) or transmit data (0). The data is exchanged until the master
executes the stop condition. More detailed information can be found in the I²C specification. The display operates
in slave mode.
The default I²C bus address is 0xDE (depending on the notation, 0x6F). The command Beispiel siehe S. 97 can
be used to re-define an x-like other address. Alternatively, this can be done via the <start.emc> file.
