Well if I were to Dream it would be cool to have MMBasic on "Bare Metal" and skip Raspbain all together! I TRUELY envy you guys that are writing MMbasic, because when I look at the Pico and pi zero I see a low cost "Every Man" PLC with out the PIA SIMATIC STEP 7 software. I've only been playing with the Picomite stuff for maybe a month and I still get Giddy and excited by every possibility every time I turn on an LED or run a motor with an L298N Motor Drive Controller, once I get interfacing my RC Stuff and Stepper Motors down the PM has unlimited potential as a Maker Lego :) Edited 2022-04-22 01:41 by Rickard5 I turned the volume on the monitor to max and could hear sound. Thanks Stanleyella |

PLC running Basic are not new. There was a Basic Stamp PLC released in 2003, and I’m pretty sure this was not the first one. |

In 1986 Zilog released the Z8 (Z8671), a microprocessor with built-in BASIC interpreter ROM, so no, it's not a new idea. I tried to get hold of one to play with but they were already obsolete by the time I tried. :( You can still find them now and again, but at about 25 UKP each I don't think I'll bother now. You still need a RAM chip and crystal to get it to do anything. Both that and the Basic Stamp were closer to Tiny BASIC though. You can't compare them to MMBasic.

I've just received my order of the Waveshare zero's. Eagerly connected it up the same way I have done with numerous Picomites and loaded V5.07.03 and it all worked well,(I could load and run a program) until I disconnected it and tried to connect again, Windows did not recognise it. Windows only sees it when I use the initial boot method to load MMBASIC This happens on my Surface Pro as well as a new Dell Laptop. Also tried V5.07.04 and same thing Any ideas would be welcomed |

will the RP2040-LCD-0.96, a Pico-like MCU Board Based on Raspberry Pi MCU RP2040, with LCD work ? I turned the volume on the monitor to max and could hear sound. Thanks Stanleyella |

Check all the hardware: I/O pins (where are they connected etc) & LCD (same hardware as is supported? etc). Are all the numbers (pins, addresses etc) the same... just check, check, check. Er... didn't you do all that before buying??? John Edited 2022-05-11 17:24 by JohnS |

Oh don't get me started on Siemens  Right now, I'm ripping-out a brand-new Simatic-7. Some clown believed that he could control a 5-axis CNC Tube Bender with it....WRONG!!! It's getting 4 PicoMites, 3 of which are PLCs and an 8-core Parallax-P2 (for the real-time motion control). Got about $8K of Siemens stuff here that I can let go for a fraction of that amount.

I'm surprised the S7 can't handle it - if they used the right modules. They can be damn fast, especially with the intelligent cards and the later processors. Whether the programming is up to scratch is another story, and using the basic IO modules will slow things down. The trouble with that stuff is that it's expensive to get the clever bits.

Too much coordination and collision avoidance, constantly switching between master/slave axes. Not to mention interpolation. There's a lot more going on than what the video shows. Regular CNCs such as mills, lathes, plasma-cutters is child's-play in comparison. Craig |

@ GlenO - It worked fine for me. Windoze 10 Pro. Plug it in, and connect to the COM port just as any other PicoMite or MicroMite. Are you on Windoze 11 by any chance? Smoke makes things work. When the smoke gets out, it stops! |

@Grogster Why just me haha The surface pro is Win11 Home edition the Dell Laptop is Win 10 Pro I have also tried connecting via a powered hub in case the demand on the USB 5V was too great, still no go. I have another, untested, module which I will have a go at. I was a little lax on my anti-static precautions when I did played with the first one so I might have altered the smoke inside a little. Will let you know how it goes |

@Grogster I tried the other WS Zero and I get roughly the same problem. It looks like a driver issue. Any chance you can check what driver your Windoze uses? |

Under W10 and W11, the pico should use Microsoft drivers. It appears as a USB Serial device. One problem I had with the pico, it didn't like any other activity (from other devices) on the USB when installing. I had to put the pico on a separate hub all to it's self. I don't know if things have improved. Jim VK7JH MMedit  MMBasic Help |

@ GlenO: I guess you have already tried a full restart? Not just a reboot, but a full shut-down and restart. This will reset the USB sub-system at a hardware level, by powering it off totally. Warm shutdowns or reboots don't necessarily do that. As Jim says, I am just using the standard MS USB driver that comes with W10 for my board, and it picks it up fine. I've tried a few times now, and it picks it up every single time. Remove ALL USB connections(except keyboard and mouse if they are USB), and try plugging the module DIRECTLY into your machine(s) - bypass any USB hubs for now, just to see if you have a hub problem, as that can(and does) happen. Keep us updated! Do you have a standard RP Pico module? If you do, if you plug THAT in, does it connect? If the WS one won't talk to you, as the hardware is essentially the same as far as the USB is concerned(directly into the 2040 chip via a couple of tiny series resistors), then I would expect the Pico module to also NOT want to talk - if there is indeed some kind of driver issue.

@Grogster Yup, went through all the obligatory troubleshoot steps, a few times, but no go. However,,,, I connected the 2nd WS Zero to an older surface pro and it worked just fine. I then connected it to the original surface pro and it works on there now as well The first WS Zero seem to be useless. I wonder if they will replace it? Ah well, chalk it down to experience. Thanks for the help. Edit: how did you get to the onboard LED. Would you mind sharing the program? Edited 2022-05-14 10:45 by Glen0 |

You are correct - you might just have a dud module. If you are interested in me testing it for you as we are both Kiwi's, let me know via a PM. My testing code for the onboard LED: 'WS2812 LED tester DIM b%(2)=(RGB(red), RGB(green), RGB(blue)) SetPin GP16,DOUT DO For X=0 To 2 BitBang WS2812 O,GP16,1,b%(X) Pause 100 Next LOOP SUB RGB_OFF BitBang WS2812 O,GP16,1,RGB(black) END SUB Run the code to cycle through the three primary colours on the 2812. As the 2812 has it's own little controller chip inside, stopping the code will NOT turn the LED off, neither will entering the editor, so use the "Command" RGB_OFF when you stop the program with CTRL-C etc, to turn the LED off.

Thanks Grogster Those certainly are bright LED's. I will order more boards if I find a need for them. I don't see any economical sense in sending the dud down to you but thanks for the offer. |

GlenO I had a similar problem of a waveshare zero that stopped working for a while. Every day I tried to resurrect it. I could get it to reload the .uf2, but not show up on the TeraTerm Serial port choices. After 3 days it started working again. I think it happened after I reversed my USB-C plug. Try different cables (if you have more than one) and different USB-C plug orientations. Glad I didn't throw it away, it works great again. I know there are some wiring differences depending on orientation of USB-C and the receiver implementation. |
