74HCT688 Datasheet PDF

Nov 9, What the Wileyfox Smartphone Gets Right A new player as a rogue smartphone has emerged in a competitive market: I don’t know why anyone would want to do something so simple in such a time-consuming way. Equality Comparator question Posted by onlylonely in forum: If so, what duration for the output? Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by beowulfNov 8, 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??? Nov 10, Do you already have an account? Jun 6, 3, 5, You did not say which PIC you are using? Now for my question, is there a faster way to implement this routine?

Yes, subtraction is the way to go. I attached the datasheet of 74HCT Feb 12, What is unstated in the problem is the data rate, which determines how long we have to process each incoming data chunk. Apr 24, 7, 1, When the strobe appears, copy this port to another file register take a “snapshot”.

Nov 9, 5. Something to duplicate the function of 74HCT equality comparator. Use a ‘computed goto’ with destinations 1 for each of the possible 7-bit values. Nov 9, 3. Embedded Systems and Microcontrollers. Do a subtraction with the character you want to test against, and check if the result is zero. The default is 4MHz.

Yes, my password is: 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. Be careful crossing code page boundaries. I wrote the equivalent in C tacked onto the end of a program I’m working on and compiled it. Nov 9, 9. Where and how to simulate an equivalent circuit for Posted by selvac19 in forum: Nov 9, 4.


Nov 9, 2. Wileyfox delivers an SD card, a big battery, security and a bit more.

Oct 14, 1, 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. Quote of the day. Thus we have at least 20 74hct68 in this 20 uS slice of time.
