sir i really like your dressing sense

[@EngineeringFunda]

So nice of you

[@EbrahimZare-5366]

Hi: I watched your video, it was great, I have a question, I connected the 82c55 to the STM32F407 ARM IC, but I don't get any output from 82c55, and when I start it with the Mega 32 IC, it works. Its power supply is 5V, but the data and control input signal from ARM to 82c55 is 3.7V .It is possible that the 82C55 IC does not work with 3.7 input data

[@EngineeringFunda]

Yes, you need to see signal compatibility as well.

[@abhassingh9174]

8259 operating modes ?

[@muslimah_905]

sir what is hand shaking concept in interrupt .???

[@EngineeringFunda]

Before transferring data, connection establishment requires some signaling which is handshaking.

[@sai01_]

Sir for need for 8259 programmable intrupts controllers . Wecan draw this and write theory ?

[@EngineeringFunda]

Yes, sure
