 tuxinator2009 | Oh, right lol 😆 | 22:49:59 |
 spinal_cord | Got 16bit audio playing on pwm, the screen still makes noises, but it plays. https://github.com/spinalcode/pwm_audio_pokitto/tree/main I can't do faster than 11025, not sure if its my code or something else. But with float volume you don't loose any quality at low volume. | 22:52:34 |
 carbonacat | I'm not sur how costly is the context switching 🤔 | 22:52:38 |
| carbonacat | with float volume you don't lose quality? 🤔 I think the MCU doesn't think in term of floats but ints | 22:54:11 |
| carbonacat | the thing is for 22khz you'll need to read twice the number of samples (which, if you don't increase the buffer size, means twice the reading operations from SD card) and twice the interrupts to write them to the PWM | 23:03:04 |
 fmanga | screen noise aside, did it solve the hiss problem? | 23:28:47 |
| 12 Jan 2024 |
| spinal_cord | I assume it will sound a lot better as the hiss was introduced before playback when converting to 8bit pcm. I'll have a look at how pwmwrite works, hopefully possible to remove some of the floats. | 09:27:12 |
| carbonacat | if you can measure how much time left you got each frame with just the sound on it'd help you optimizing | 09:30:34 |

| blixten3140 | I like to get a Pokitto, but the shop (https://www.pokitto.com/shop/) says: "Pokitto DIY Game Console (note: not available, new version coming soon)"
Is there any news about the new Pokitto (when and/or what the difference will be)? | 12:17:13 |

I have bought the two magazines, just to have something 🙂 | 12:18:48 |

| blixten3140 | Thanks, Mr Pokitto. Keep up the good work, and make me (and others) happy. 🙂 | 18:18:54 |
| spinal_cord | Well, after getting 16bit pwm audio working, it seems it is not fast enough for my game.... oh well. | 21:49:17 |
| spinal_cord | Not only that, it seems the Pok makes a lot of noise on the pwm, so playing quiet is no good as you can hear the screen update more. | 22:03:42 |
| fmanga | "not fast enough" as in, the game doesn't update often enough to keep the buffer full, or does the fps drop just because of the pwm code? | 22:22:32 |
| spinal_cord | not sure, wither the timer doesn't fire enough, or it's not reading the file fast enough. I'll stick with fuzzy 8bit, | 22:29:50 |
| fmanga | How many khz did you set it to? | 22:46:18 |
| spinal_cord | 11025 | 22:58:21 |
| spinal_cord | in my stand-along project, if I set it faster than that, it didn't play the music any faster. So it takes too much time, my guess would be the float calculations. | 22:59:07 |

 homineludens | Saw this long time ago, but still very cool | 07:56:29 |
 Jonne | That was a really cool illusion, I had not seen that | 07:59:44 |
| spinal_cord | Remove the float helped a lot. I wonder what resolution the pwm is. I assume I'll be losing data one way or another. | 12:12:21 |
| spinal_cord | wouldn't make any difference, even removing the floats, it slows down my game loop too much. Looks like I'll be sticking with fuzzy 8bit pcm afterall. | 16:01:14 |
| Jonne | Just because we can not do it dpes not mean fmanga can't make it run at 150fps | 16:13:01 |
| Jonne | * Just because we can not do it does not mean fmanga can't make it run at 150fps | 16:13:10 |
| spinal_cord | But then I don't know if wpm sound better than 8bit ¯\_(ツ)_/¯ . | 16:24:50 |

 tor.sh | Starting a new project and having my kids help me with generating ideas. It is obviously going chaotic lol. They keep suggesting Minecraft things to me. And I am telling them "That just won't work in a 2D farm game guys." | 18:09:05 |
