 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

It took a couple times to get it loaded but it works great!!! Thank you for taking the time to release this version. I will be doing some playing now. Jack |

If PSRAM is not detected, there are now two builds: Octal (usually should work for newer boards) https://github.com/jvanderberg/PicoMiteAllVersions/releases/download/latest/MMBasic-Anywhere-esp32-s3-octal-merged.bin Quad (for older boards, usually less psram) https://github.com/jvanderberg/PicoMiteAllVersions/releases/download/latest/MMBasic-Anywhere-esp32-s3-quad-merged.bin Also it now autodetects PSRAM size instead of allocating a fixed 6MB. Also give 'frun' a shot, this is the bytecode compiler. It works only with a filename. 'frun "sieve.bas"' and re-reads the file every time, unlike 'run'. But it runs some code significantly faster, and for graphics on the esp32-s3 with LCD, it can be significantly faster. |

 Here is the benchmark speed test for the esp32-s3 version of basic. I am happy to get some use out of those boards that were wasting time in my bench drawer. |

Did you try ‘frun’? |

 Ok , I used [frun] on the bench test i posted before. pretty big change.... Jack |

| gadgetjack Senior Member Joined: 15/07/2016 Location: United StatesPosts: 233 |
I did have to change all " if " statements to " if then " before it would compile right. Other than that , no worries. |

Can you send me the program it should be source compatible. |

Benchmark.zip This is the file we have passed around for a while to test the pico speed. When i tried it in "frun" it came back with "if without then" error. I added a then to each line and then it was fine. That was the only error it gave me , rest ran ok and faster. Jack |

Yeah 'frun' is it's own parser, so rare syntax forms sometimes get missed. I'll post a fix for this soon. It's about 10x faster than the interpreter on this benchmark. |

No complaints from me. I am having fun with this one. If you ever get any lcd or vga drivers for it , please let me know. Till then , Thanks again!!! Jack |

| jvanderberg Regular Member Joined: 06/05/2026 Location: United StatesPosts: 82 |
Oh, it's got vga drivers - I've only tested 3 bit color, but the readme shows how to configure it for more. It has an LCD driver, though I am not sure how usable it will be in general. It supports the FREENOVE 2.8" touch panel, which is a generic IL* LCD, but it's not wired in as a general LCD panel, only as the FREENOVE configuration. It should not take a lot of work to get it working with a different panel, just needs to GPIO mappings. |

I don't know where it comes from, but the execution times are rather inconsistent. I have wrapped the sieve.bas with a do/loop construct to have it run forever. If I look at the execution times of the individual sieve-runs they are very different.

TLS was left out for space reasons when bringing up the port, it's on the list. |

MMBasic-Anywhere-esp32-s3-octal-40MHz-merged.bin.zip For the octal psram crash, here's a version that clocks the PSRAM slower. It might not work, but this could fix the issue. If it does, I am not sure what I will do. I don't want to really clock the PSRAM at half speed because some boards crash. The 80MHz version runs well with wifi locally on the board I have. Let me know if the 40MHz fixes it. |

| ville56 Guru Joined: 08/06/2022 Location: AustriaPosts: 531 |
@jvanderberg, the octal psram issue seems to be fixed with the 40MHz version. It boots up fine, connects to wifi and is responsive. Maybe it's an option to throttle down psram speed after a crash reboot and give it a second try. As already stated, Annex Basic RDE runs fine on this modules. I don't know how the developer did handle this issue in Annex and how fast psram is clocked there. 73 de OE1HGA, Gerald |

Sadly it’s a compile time only option so I’d have to offer a quad, octal 80 and octal 40. Which is confusing :) |
