Nice Solution. Mine was much more complicated. 👍 I did a partial solution and then had to go back and fix it!
@jameslewellen150 6 күн бұрын
My solution was a little flaky, sometimes the red and the yellow would switch positions randomly. Hope Paul's solution fixes that problem. This PIO State Machine is pretty hard to fathom.

Nice video, James You said that you could run out of space for the instructions in the PIO blocks if you had lots of state machines. This isn't the case. If all the state machines use the same asm_pio declaration, then they will share the same instructions in each PIO block. If you have the servo running on state machine 0, it will take up the space in PIO block 0 for 6 instructions. If you then add servos on sm1 and/or sm2 and/or sm3 then it will still only take up the space in PIO block 0 for 6 instructions. Similarly, you can add servos on PIO block 1 (state machines 4, 5, 6 & 7) and It doesn't matter whether you add 1, 2, 3 or 4 servos - it will still only take up the space in PIO block 1 for 6 instructions. Sorry, I haven't explained very well🙃🙃 Also, Paul wanted us to hide all the PIO stuff so that it would be easier to understand for people who know nothing about PIO. Therefore you could insert this line 'class JamesASM:' between lines 1 and 2 and indent everything up to and including the 'wrap()'. Then all you have to do is to change: self.sm = rp2.StateMachine(self.smNo, servoSet, to: self.sm = rp2.StateMachine(self.smNo, JamesASM.servoSet, and you will have hidden all the complicated PIO stuff from prying eyes AND it will make lesson 101 a whole lot easier. Don't be tempted to put the asm_pio in the servoSetup class. That's what I did initially and it screwed things up. Feel free to completely ignore everything I've said😁😁
@jameslewellen150 27 күн бұрын
Thanks for the comment, like the last statement. The PIO instructions with multiple servos helped keep things in control. I could only setup 2 servos as several of my servos in the various kits that I have, died. I have watched your video several times and still don't know what you are doing. Its just to complicated for the old guy like me to fathom. I see that it works but I could not follow it. Probably not your fault, more like mine.
@charlotteswift 27 күн бұрын
@@jameslewellen150 I've just looked at my program and I'm not surprised that people can't understand it because I put in so many different features - a generator function, classes inheriting from another class, class variables above the __init__, dictionaries to keep track of how many instructions in each PIO block, allowing all the servos to be completely independent rather than just mirroring each other and the various ways of sweeping. I added things one at time which made it easy to understand but I can see that looking at the finished product would be horrendous for anyone other than me!! Anyway, the main part of my comment was that 1, 2 3 or 4 state machines using the same asm_pio program in the same PIO block use the same instructions.

With the link just look up Paul McWhorter and look at the playlist. I have been involved in electronics for over 50 years. I am retired and like to keep my skills sharp. However, I was not into coding software. I was a hardware guy. This is something I always wanted to do. Love the way Paul teaches the courses.

H James I like your little screen and also how you can turn the annoying buzzer off. Unfortunately, you've got your timings wrong. dah should be on for 3 units and off for 1 unit. Also, you turn the buzzer off for 1 unit at the end of dit and for 3 units (should be 1 unit as I said above) at the end of dah, therefore the delay after each letter should be 2 units. This is probably why you found it hard to hear the pause between each 'sos'. If you fix these bugs, I think that a delay of 7 units would work fine. Obviously this should be coded as 6 units because of the i unit delay at the end of the last dit in 'sos'. Sorry to be so negative😿😿

The tft display library needed a change to Adafruit_ili9341,cpp look up the error code wiring_private that initially comes up and search on that. The fix to that file works. I fixed the file and saved it separate from the library so if things go wrong I have the updated file.
