PIC MCU TUTORIALS #11 - Oscillator block & Clock generation (Absolute Beginner)

In this video, I'll talk about the oscillator block of our microcontroller, which is responsible for generating the clock signal required by the microcontroller. Clock refers to a switching signal that has a constant frequency and is used by the microcontroller to synchronize its operations. I'll talk about all of the available ways for you to generate this signal using the built-in oscillator block...

I was searching all over internet for good PIC tutorial and landed here, well explained and good narration brother

[@entropyz5242]

Dude I’m an AE and I understood this super well. Thanks for the clear explanation

[@GodsOnlyMonster]

bro your tutorials are amazing, please continue your series

[@yousefsrour3316]

Well explained, Thank You !

[@kaumohlamonyane272]

This is well made

[@nadernommen9780]

Thank You !

[@alejandrobanolescobar6160]

Thanks a lot sir

[@jackski5732]

There should be a list of NON RUN TIME bits

[@Microesque]

There actually is, I talked about it in the "configuration bits" video. Just search for "Configuration Bits" in the datasheet and go from bottom to top. For this microcontroller (PIC18F46K22) you can find it in the page 344.
