You did not say which PIC you are using?
A separate active low output for each character? What the Wileyfox Smartphone Gets Right A new player as a rogue smartphone has emerged in a competitive market: Do you already have an account? No, create an account now.
Thus we have at least 20 instructions in this 20 uS slice of time. I wrote the equivalent in C tacked onto the end of a program I’m working on and compiled it. Now for my question, is there a faster way to implement this routine? Be careful crossing code page boundaries. Thanks for the replies guys. If we make no assumptions about when this clock signal occurs during the valid portion meaning the hold time may be zero then we just have the clock time to read the data.

Where and how to simulate an equivalent circuit for Posted by selvac19 in forum: So it seems you’re looking at a stream of 20 character records with at least 50 usecs between the start of one character and the next Nov 8, 1. Nov 9, The default is 4MHz. Apr 24, 7, 1, Embedded Systems and Microcontrollers. Nov 9, 8. Nov 9, 6. In this case data is assumed to come in on PortD, and PortB. If you have the PIC16F or I don’t know which other processors, you have a “parallel slave port” available.

Lol, why i didnt think of that the first time??? The contents of PortD are latched by an external strobe, which also causes an interrupt, or a flag that you 74yct688 poll.
