SPI
Das Serial Peripheral Interface is a bus system for a serial synchronous data transmission between various ICs.
The bus consists of the following lines:
l MOSI (Master Out → Slave In) otherwise known as SDO (Serial Data Out) or DO
l MISO (Master In ← Slave Out) also known as SDI (Serial Data In) or DI
l SCK (Serial Clock) - shift clock
l SS (Slave Select → Addressing the partner), also known as CS (Chip Select)
SPI works with a bidirectional transmission principle, i.e. data is exchanged between the partners simul-
taneously. Every communication is determined by the master with the aid of the SCK line. The display works in
the slave mode.
The log for the data transmission is not laid down with SPI, so that there are various configuration options. These
are laid down by the parameters of clock polarity, clock phase and data order:
The SPI-Mode 3 with DORD=0 is preset. The command Beispiel siehe S. 97 can change the modes 0..3. Alter-
nativly you can set this command also in the file <start.emc>.
