How to convert external Interrrupt to Multiple Interrupts

Can anyone show me schemmatic for this. If you ‘Or’d the 8 to generate the intr, how would you know which source was requesting the intr??? Media New media New comments Search media.

Input source 0 has lowest priority and source 7 has the highest. I believe that it even has the same pinout as the By continuing to use this site, you are consenting to our use of cookies.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at If ‘one of the eight’ ext sources, requesting an intr, generated a 3 bit code which is unique for that source, then the PIC prog would know which Interrupt subr in your prog hfe execute.

Hi, Hf you will want to know which is the interrupting source, you could use a HEF 8 input priority encoder. Hi Eric, I will answer your question: Have you read the datasheets on priority encoder devices?

I think it should do what OP wants, he didn’t say how many ext interrupts he had in mind. Forums New posts Search forums. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Articles Top Articles Search resources. Papabravo Well-Known Member Feb 28, Thread starter prevravanth Start date Feb 27, Also there is a common intr output pin, to drive the MCU’s intr pin.

Datasheets, Manuals or Parts.

What does the 3 bit address related to the calling source do I am totally confused. A PIC prog reads these 3 input port bits, so it knows which ext intr to service. How to convert external Interrrupt to Multiple Interrupts. This will give a 3 bit address related to the calling source, these 3 lines would go to 3 input pins on the MCU, so that you can determine which intr source needs servicing.

Pioneer Elite vsxtx water heef no power Started by Watin 15 minutes ago Replies: So a decision has to made which ext source has intr priority. No And continue your, well explained, story These are also priority encoder circuits. This is what the priority encoder does, it encodes a 3 bit pattern, which unique for each external source.

Depending on the value on these three pins 0 to 7 you will know which interrupt line, on the “priority encoder circuit”, you have hf service. Welcome to our site!
