Hello, I have looked through Orangutan SVP (1284) documentation and also through this forum and haven’t seen the answer I’m looking for. My apologies if asking a repeat question or missing some obvious calculation…
I am using I/O ports C1,C0,B4,B3, and A0-A3 as inputs to 2 separate line decoders (the output on the Orangutan ports are plugged into line decoder inputs). My application requires that these change between high and low frequently. I understand from the code processing perspective that the quickest method is to send HIGH or LOW to the port directly (i.e. set_digital_outputs(IO_A0, HIGH) vs. set_digital_outputs(IO_A), some_function_to_set_state()). However, from a hardware standpoint, what is the minimum amount of time required to go from 0 to 5v on a digital I/0 port? For example, I may set ports A0-A3 as LOW, HIGH, HIGH, LOW for 25 ms, then the next iteration (which would also last 25 ms) may be HIGH, LOW,LOW, HIGH. Will A0 be able to reach 5v in 25 ms? I am trying to determine the smallest iteration period that I can use for updating the state of these ports.
