Nov 9, Where and how to simulate an equivalent circuit for Posted by selvac19 in forum: Posted by new in forum: Embedded Systems and Microcontrollers. If you have the PIC16F or I don’t know which other processors, you have a “parallel slave port” available. A separate active low output for each character?
Nov 9, 5. Use a ‘computed goto’ with destinations 1 for each of the possible 7-bit values.
Then take as long as you like to decode. Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by beowulfNov 8, Nov 10, Aug 21, 11 0. I attached the datasheet of 74HCT Be careful crossing code page boundaries. Nov 9, 6.
74HCT Selling Leads, Price trend, 74HCT DataSheet download, circuit diagram from
If we make no assumptions about when this clock signal occurs during the 7hct688 portion meaning the hold time may be zero then we just have the clock time to read the data.
Jun 6, 3, 5, Yes, my password is: Nov 9, 4. If so, what duration for the output?
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 Maybe this can solve my timing issue Nov 9, 2. The default is 4MHz. Nov 9, 3.

Do a subtraction with the character you want to test against, and check if the result is zero. What is unstated in the problem is the data rate, which determines how long we have to process each incoming data chunk.
