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. Feb 6, 3. Only a few lines of code. When the flag is clear timer stoppedset the register to your timing value. But can be any fixed rate. When the register reaches zero — the time delay is complete and you stop decrementing.

Better alternative to DS Posted by stoopkid in forum: Feb 24, 11, 2, 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 Have a flag a bit that controls this timer from the code outside the interrupt.

Jul 12, 4. Feb 9, When the flag is set timer running decrement the register every interrupt. Feb 6, 9. Feb 6, 1. Makes calculating the timing easier. Feb 6, 4. Feb 6, 7. Feb 6, 6. Nice if it can be every millisecond, for example. Jan 6, 3, 1, Your name or cv address: Do you already have an account? No, create an account now. The perfect approach for me is 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.

Alternative to BF Posted by toughspeaker in forum: There are many ways you can implement delays without going into a dedicated delay loop. Related Articles

The device is retriggerable and resettable, and the control inputs are internally latched. Two trigger inputs are provided to allow either rising or falling edge triggering. The reset inputs are active LOW and prevent triggering while active. Precise control of output pulse-width has been achieved using linear CMOS techniques. The pulse duration and accuracy are determined by external components RX and CX.
