Generation of single pulse (1ms with voltage of 3.3V)

[evangel55]

Hi,

I would like to generate a single pulse with pulse width of 1ms and voltage level of 3.3V. My initial approach is to use analog output to generate this waveform but I realise that its rise time is too long. Therefore, is that any other methods to generate this pulse?

Thanks!

You could use a counter to generate your pulse: surely you will have better slopes, but you will  need to condition the output signal with some external circuit since counter usually work at TTL level (5V). Some example code here

Hi,

Thanks for the reply. I think I will design a simple circuit to condition the signal!  😃
