Voltage given out when HIGH

Archiver

hi,

I've a very basic program with BS 2

DO
HIGH 14
LOOP

by using a multimeter (+ at PIN 14, - at GND), the voltage 2.32V, I
would like to have a output voltage from 4V-5V when HIGH, is there
anyone know anything about that?

The pin output should be between 4.7v and 5.0v when HIGH. Perhaps your
meter is funky, so try this: connect a 10K resistor between the pin (14)
and ground. Measure across the resistor.

A multimeter is good to measure standard DC or AC (standard frequency)
signals, using the respective scale (or even the auto-scaling feature).

Your program is generating a fast 5 V pulse that doesn't fall in any of
those categories.
Whenever you have a non-standard signal, you need to use an oscilloscope
like the OPTAscope to see its shape and measure its voltage on the
oscilloscope screen.
