Raspberry Pi Pico W LESSON 87: Introduction to Raspberry Pi Pico PIO and State Machines

yay. the paul mcwhorter treatement of PIO. all will become clear. cant wait.

Hello Paul,
Glad to hear that you will introduse PIO's in your class. 👍
PIO's - this is magic, as you are too.... 👋
PIO's are doing a lot of stuff in my projects, silently on the background. ie.:
- watchdogs,
- driving some devices attached to the PicoW just on the change of the single variable, taking that load off the main process (also checking a lot of conditions)
- taking entries from some anusual devices
- and more...
Can't wait to refresh the basics. I know that some code I could do better just with different prospective.
Some times routine kills the project, by making it to complex instead of simplifying it.
That is why, with plesure I will take your lesson, to see if I can change my prospective in some of my projects.

So your classes are for Absolute Begginers as you said in the title, but I think it is not so true... Advanced coders can also take something out of them....

Can't wait,

Hello again,

Paul, just for my curiosity... Are you going to introduce the DMA channels in the future? or I missed them i your earlier episodes. DMA are great to move chunk of data between channels or buffers, offloading main CPU.

I need more pi!!!

Thank you Paul

I think I will need to re-watch this episode a few times again.

Hey Paul! I remember watching your arduino tutorials, which we're so great!
I followed your ice-cold coffee routine and been studying for 2 years straight! always makes me think about you and sending my thanks whenever I have a cup!

Raspberry pi pico w or Raspberry pi zero 2 w???

Just checking in on you Paul!

I followed ur CAD, python, OpenCV Ai, and ur engineering mindset/keys of success series and I just wanted to let you know how much you’ve helped enhance my passion and ability for engineering! I’m now studying at UCLA for mechanical engineering, and you made that transition so much easier. I try to tell fellow engineering buddies that struggle with software aspects etc to come to your videos whenever I have the chance.

The “Paul M University” experience is like no other.

Thank you for doing what you do!

Thanks Paul! This was an archeological dig into the past, lots of spiderwebs, and lots of fun revisiting this subject considered by many a no-go zone : )

Good lesson. I was able to view the recorded "Live Rumble in the Jungle" prior to the lesson 87 release. Those 2 videos complimented each other. I was able to complete the homework and follow the manual input through the cycle laid out in your pictorial diagram. I am still working on clearing out all of the LEDs (resetting to 0) when a number outside of the range 0 - 15 is entered. Currently, the LED's stay in the last valid state until as valid number is entered (0 through 15). The lessons keep getting better. Good pace!!!! Thank you.

Thanks Paul!

Another new subject, having problems under standing, years since i did assemly laugage programming(1970s). I came across a pdf helping with state machines "RP2040 Datasheet.pdf" chapter 3 is about what you are teaching and may help others undestand a bit more.

golden. view B

Nice tutorial, Thanks Paul ! Btw I like B

I am a fan of yours and I sincerely thank you for what you do. Please don't stop with each lesson it becomes more and more interesting (this lesson will have to be watched 3 4 times :) )

Glad to see you decided to do videos on the assembly language of the pio state machine.
