parallel port clock
Hi,
I am trying to write some C++ code to write data out over a SPI link using the parallel port.
I can write the data as expected, however the throughput is just not fast enough. The time between clock cycles is 8us this need to be 1us, is there any way to improve this?
If I just add a section of code to toggle the clock line 1,0,1,0 etc... the quickest it gets is still an 8us clock period. Is it even possible to write at 1MBs serially using the parallel port?
