A separate active low output for each character? Your name or email address: 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 10, Thanks for the replies guys.
The default is 4MHz. How to convert c code to 74hc688 code for pic? Nov 9, Oct 14, 1, Nov 9, 9. Nov 9, 8. No, create an account now. Be careful crossing code page boundaries. May 11, 5, 74hct6888, An Introduction to Programmable Logic Learn about a hardware-based approach to performing calculations, routing digital signals, and controlling embedded systems using programmable logic and FPGAs. Datashret don’t know why anyone would want to do something so simple in such a time-consuming way.
If so, what duration for the output?
Use a ‘computed goto’ with destinations 1 for each of the possible 7-bit values. What is unstated in the problem is the data rate, which determines how long we have to process each incoming data chunk. Then take as long as you like to decode.

You did not say which PIC you are using? Nov 8, 1. Do a subtraction with the character you want to test against, and check if the datassheet is zero. Feb 14, When the strobe appears, copy this port to another file register take a “snapshot”.

As for testing the incoming data, why do it bit by bit? The contents of PortD are latched by an external strobe, which also causes an interrupt, or a flag that you can poll.
Posted by new in forum: Nov 9, 2. 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.
Maybe this can solve my timing issue Something to duplicate the function of 74HCT equality datassheet.
Nov 9, 3. Equality Comparator question Posted by onlylonely in forum: In this case data is assumed to come in on PortD, and PortB.
