Thanks... the interesting part is still to come: hook it up with a display buffer drawn on and written to by the Graphics class.
I see you point... but there is no pixel buffer... the interval around the SPI1 write - the write of just one row gets the brightness from the duration it is on... . it is really low level. may be you are talking about the fip... flip Graphics buffer into display buffer... yes there is no delay what so ever to plan. I'm interested too what this constant multiplexing 'costs'...will do sometime a bit later.
