Hello @all,
i searched the TI led-drivers and forum and found TLC5949 -
if i have read the short overview and diagrams correct this normally needs 4 pins to be controlled.
i don't have full read & understand the datasheet yet -
i think the Auto Display Repeat and Auto Data Refresh bits could be used to get rid of the LAT signal.
is it possible to use the SCLK also for as the signal for the GSCLK?
with this i could get down to 2 pins / signals?!
i know that it will get confused if the clock signal gets interruppted or paused -
so then i would need to make sure that my driving microcontroller never stops the SPI-Clock.. (i have to read into this..)
thanks for any tips regadring this :-)
sunny greetings
stefan
