 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. |

You don't say which version |

What operating system and terminal program? I'm W11 and can replicate with teraterm BUT NOT with putty. Looks like it may be a teraterm issue. What made me suspect was that the heartbeat was still running and the scope showed normal activity on the GPs UPDATE: just updated teraterm to 5.3 and now showing no signs of stopping Edited 2024-10-19 04:17 by matherp |

I'm using W11 and MMCC as terminal emulator. By locking up the firmware I mean really locking up. No heartbeat anymore and no activity on the single wire bus (monitoring with a scope). So I will try to replicate the problem with putty and give you info about the result. 73 de OE1HGA, Gerald |

Peter, I can replicate the problem even with putty, it just takes some time (several minutes) but it reliably reoccurs. Also on the scope things look pretty normal, conversion command and data readout. It just stops after data readout on both channels. Btw, I'm using "normal power" and 4k7 pullup. I have also tried with xon/xoff and no flow control, even though it should not make much or even any difference on the USB connection and a fast machine like the one I use. N.B.: it seems to me that with xon/xoff flow control it is easier/faster to replicate the problem, but this assumption has no scientifical robust foundation ... :-) 73 de OE1HGA, Gerald |

It is possible to send data to MMCC faster than it can handle but I would think that the delay in waiting for the conversion to be sufficient. This might be causing constipation in the pico. Does a small delay in the loop 'fix' the problem. I will try and find time to investigate later today. Jim VK7JH MMedit MMBasic Help |

Jim, adding a delay of 1 mS after the PRINT statement (and thus between TEMPR and TEMPR START) seems to be a workaround. Didn't try a shorter delay yet, will play around with it tomorrow if i can find time. Adding the delay between TEMPR START and TEMPR did not have any effect. Regards, Gerald 73 de OE1HGA, Gerald |

I've been running 3 hours WebMite with V6.00.00RC9 on Teraterm 5.3 with the code as posted and no issues so I don't intend to look at this any further |

That rings a bell. Have seen it before when printing to the console too fast. My guess is either the Tx buffer in the Pico, or the Rx buffer at the terminal eventually overflows. In that instance I think Pause 30 was needed as a lot was being sent. Correction. That was sending to MMB4W via Com 1 and USB/TTL. Edited 2024-10-19 09:00 by phil99 |

I ran the code as supplied and with a loop counter. No problems with my webmite running RC9 no need for any extra delays. Tested on USB and Telnet and both ports sat on ~517 reads per minute My MMCC might be faster than the current release. Reading the DS18B20 that fast between reads is pointless anyway due to it's thermal mass. Jim VK7JH MMedit MMBasic Help |

I'm supposed to be documenting but this seemed like more fun  This will only be available on the RP2350 Here is just the standard PicoMite version if anyone wants to play with it. The fast frequency functionality is fixed on pin GP1 and uses PWM channel 0 to do the counting. I've tested up to 50MHz using an external signal generator. I think the theoretical limit is CPUSPEED/4 but can't get a good enough signal to test at those rates PicoMite.zip Edited 2024-10-20 01:40 by matherp |

Why not use PIO? Measures up to cpuspeed/2 and can use any pin. Volhout PicomiteVGA PETSCII ROBOTS |

Did some further investigation on the DS18B20 issue. For me it seems to be connected to the USB console port. If I use the serial console only and no USB console output, the program runs reliably. As soon as the USB console comes into the game (with or without serial console), the firmware hangs randomly but always in a TEMPR() statement. Will try to narrow it down further... 73 de OE1HGA, Gerald |

Sorry to harp on about the same subject Peter... But it's back to the old nemesis  I uploaded WebMite MMBasic Version 6.00.00RC9 yesterday, did a few tweaks and fiddling, hit ^C to stop a continuous print loop in my code. Didn't think much of it and when I got hone from work this 'arvo, found this on MMCC screen - Note - WebMite MMBasic Version 6.00.00RC9 ... only to be cleared by a cold start on the pico, even though the heartbeat flashed happily. So, my code has succesfully run through the initialise stage, done the print to MMCC screen successfully at which point I stopped my code. Pico is still powered on, MMCC is still connected. Presumably, the SDK still has WiFi connected and the SDK part of the O/S is still running. I'm not sure what the clues add up to yet, but thought I'd pass the error on and maybe it will give you some fresh ideas. Until the latest version, I've been using 'WebMite MMBasic Version 5.09.00RC5 (Unauthorised Ver 1.0)' compiled with SDK 1.5, which I've gone back to. Any ideas?

The downloaded file PicoMiteRP2040V6.00.00RC1.zip contains 2 files for the 20240 PicoMiteRP2040V6.00.00RC1.uf2 PicoMiteUSBRP2040V6.00.00RC1.uf2 One with and one without "USB" in the name. My standard RP2040 boards all have an USB Port. I never saw a model without it. What is the difference between these two firmware versions and which one should I use for the standard RP2040? thongthani |

Hi thongthani, The version with the "USB" in it is prepared to connect a USB keyboard (through an adapter, or hub) to the pico USB connector. Since the USB connector is occupied, the console input moves to GP8 and GP9 (serial) The one without USB in it, is prepared for a PS2 keyboard connected to GP8 and GP9. The USB connector is the console input. Volhout Edited 2024-10-25 16:24 by Volhout PicomiteVGA PETSCII ROBOTS |

Thank you, all clear to me now. Another question, at Geoff's page the latest firmware is v 5.08.00, beta 5.09.00 In the forum here I can download Version PicoMiteRP2040V6.00.00RC1 It's not clear to me where does it come from and I could not find release notes about it. It seems the versions a geoffs page are frozen at 5.08.00 but someone in the wide world proceeds to publish updates. Is there a new official download location? Google search was not helpful thongthani |

5.08.00 is the last official release. It also has a user manual on Geoff's site. 5.09.00 is a development version with new features. There is no user manual, but you can do a lot of reading on this forum, where the differences are described. 6.00.00 is going to be the new official release (I think it is close to release, maybe even before Christmas), and will again have a user manual. If you want to try it, here is the latest development release which is 6.00.00-RC9 (not RC1, but RC9). RC9 When you are just getting started, the user manual of the 5.08.00 is a good starting point, even when working with 6.00.00. Peter and Geoff (authors of the software) try to make all improvements to the software backward compatible as much as possible. So you will have a lot of help form the older 5.08.00 user manual. And when you get stuck... we are here to help you. Volhout P.S. Welcome to the MMBasic family... Edited 2024-10-25 17:19 by Volhout PicomiteVGA PETSCII ROBOTS |

OK, I usually stay with offical releases. Also 5.08.00 from Geoffs page. New releases are still published there. Thank you thongthani |
