Re: What is software SPI speed for various OSC speeds?
If you're trying to film it actually displaying all values between 0 and 9999 in 200ms then I don't think that's going to happen, no matter how fast you shift out the data.
Nice camera 50000 frames / sec
my tm1637 code can load the 4 digits in just under 50uS [40bits] on pic18@64mhz /16mhz mssp spi clock, you could could not maintain that rate for a 0-9999 count that would have its own overheads to add in. as henrik pointed out the multiplexing would be the limiting factor there too i think.
