DSP56F80x Pwm port directly drive Leds or optocoupler? - hao yuan - Oct 14 3:54:00 2002
|
Hi everybody, May I use the pwm port with resistors drive the leds and/or optocouplers directly? I mean without any buffers as 74ls06 or 74ls07. The max current of pwm is 20ma and we can confine the currents 10ma. Is that ok? or will it do any harm to the whole DSP performance? Many thanks |
