Alternative to Xbee Posted by bencbrown91 in forum: When the flag is set timer running decrement the register every interrupt.
How are you writing the code: Feb 24, 11, 2, Is there a chip like the CD but where the clear input and “B” input are internally tied high instead of offered as pins? I don’t want to use another microcontroller to make the timer itself. Mar 14, 19, 5, Yes, my password is: This runs all the time.
Jun 19, 1, There are many ways you can implement delays without going into a dedicated delay loop. Feb 6, 9. Both serial connections and USB to serial conversion connections are covered. Feb 6, 6. I tried the CD chip and for the application it works perfectly, however to pull things off, I have to tie 4 items high from the chip itself Your name or email address: Feb 6, 7.

Then, in the interrupt routine have a variable which is your virtual “timer” – you can have as many of these as you like as you like. I also don’t want to leave the inputs floating as unpredictable results cd438 happen. Discussion in ‘ Digital Circuit Design ‘ started by testuserabcdefFeb 6, But can be any fixed rate.

When the register reaches cd45538 – the time delay is complete and you stop decrementing. This is a nuisance for PCB development as this forms the letter H under the chip on the board which prevents wires from running through. I guess jumper wires are my only real option then. Feb 6, 1.
Better alternative to DS Posted by stoopkid in forum: Feb 7, Alternative to BF Posted by toughspeaker in forum: Invest the time to learn how to fix this in software, you will not regret it. Feb 6, Only a few lines of code.
No, create an account now. When the flag is clear timer stoppedset the register to your timing value. Have a flag a bit that controls this timer from the code outside the interrupt.

Nov 23, 8, 6, Quote of the day. Nice if it can be every millisecond, for example. Jul 12, 4. Makes calculating the timing easier. I have a high-speed microcontroller application and I want to hook up a gpio pin on it to an output of a big delay external cd45338 so that I don’t have to hold up the microcontroller cpu just to count a long delay.
The perfect approach for me cc4538 two monostable multivibrators, because one will be used for the pin and another to refresh the clock on an external flip-flop connected to the micro for other purposes. Feb 6, 8. Feb 6, 4.
