Can anyone tell me if an interupt routine can be tested without having to blow a chip and have it in circuit.
I am new to this and have just about finished my first draft of my prog and was wondering whether I had to put an additional routine to simulate what would be seen on ra0 or rb0 when...
Thank you for your guidance.
Is an interrupt routine something you code yourself or is it something you call that is already resident in the chip.
Going to work now so hope to read this later.
I am a Noob but I am trying to learn from the datasheet and strugling.
I want to read in 5 pulses and then output one pulse for 1.5 seconds.
I can do both myself but I can not do them simultaneous. My program is a right mess now so I am going to start again. I have not used tmr0 yet but I am...
More Info, I hope this helps.
Thanks for your help guys.
The welder is a mig on UK 240V.
It has a four position output switch giving fixed power outputs of increasing power.
What I was wanting to do was take the power from any of the selected positions and then manipulate this power by...

Thanks for your help.
Please accept I am a total novice and lacking confidence.
What I am trying to achieve is the switching of the output power to stop too much heat going into thin metal.
I dont know what power is drawn but the machine has a max output of 150 amps but that...
I only have old dormant NE555 experience, is this enough for a timed pulse or are there new devices these days that supersede this chip.
with the power being high amps there will be heat generated. So do I use a relay or some kind of isolator.
the power source is 240v and a welder...
