DRIVING THE SYMBOLS
After power-on symbols will
be set accidental. To switch
off them all please refer to
the example of initializing
on page 3. To display an
individual symbol have a
look
example at the right.
Each symbol can be
displayed in normal (solid)
and blinking style.
SERIAL MODE SPI
Factory set for interface is parallel with 4 bit or 8 bit data bus. Alternative module can be programmes
with serial data stream. For that solder link 4/8 has to be opened and closed to SPI side. Harware
specification for serial operation mode is written down in user manual for KS0073:
module.de/eng/pdf/zubehoer/ks0073.pdf. Software for initialisation and programming keeps the
same.
