Harm: Here is a corrected version for the VGA for you to test. PicoMiteVGA.zip I have tested against this option base 1 dim a(2,5)=(17,5,25,21,39,34,42,49,32,25) ? math(chi a()) and this option base 1 dim a(4,3)=(90,60,104,95,30,50,51,20,30,40,45,35) ? math(chi a()) NB: Now also allows C_MUL and C_MULT |

Hi Peter, Spend yesterday night to check the MATH(CHI ) function, it works okay in this beta. But for my project, it does not give the correct decision criteria (I tried it because I hoped it could be used as a correlation filter) (*). I will have to do more analysis to find a better filter for the data. I already have a good idea how to do it, but wanted to stay within the 10ms sample loop. That means I cannot add a lot of MMBasic instructions for each data point (like a FIR filter implemented in MMBasic). So I am looking at using the best combination of MATH instructions. And I have some new idea's I have to try out next. The path I was on before I tried the CHI function has the best papers. Thanks for fixing CHI never the less. Volhout (*) I wanted to correlate spectral plots, and am interested in the correlation over time. That means that the carrier column is dominant, but in the CHI number the noise contribution is equally dominant. And I could have known since the foruma for each cell is (obs - exp)2 / exp.... Division by expected makes the weight for each cell equal. Edited 2024-02-29 18:30 by Volhout PicomiteVGA PETSCII ROBOTS |

Harm: Can you give me more idea what you are trying to do. I've got a pretty good, historical and mostly forgotten, grounding in stats so may be able to provide some input |

Version 5.09.00b4 https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip Fixes bug in MATH(CHI Allows MATH C_MUL and MATH C_MULT Fixes compile error with PICOMITEUSB version NB: Installing this version (PICOMITEUSB) will delete the A: drive and all options |

Hi Peter, As (editted above). Project: morse decoder I want to filter carrier tone (dit - dah) out of noise. I am putting audio in the ADC of Pico (GP26) and use pingpong buffer to miss nothing. I need 10ms time resolution to be able to make good decisions on fast morse. I run the ADC's at 3.2kHz, using 32 sample buffers ->10ms The FFT of the 32 samples gives me 100Hz resolution (bins) that will tollerate some BFO drift of the receiver. So I have a bin for DC, a bin for 100Hz, a bin for 200Hz....a bin for 1600Hz. At the moment I use 2 pieces of information, and need to combine these Find the peak in each spectrum, and the associated bin (MATH MAX a(),f%). - use a low pass filter on the bin (i.e. best 3 of 4 using MATH(SD bin)), so I can decide better in a noisy environment. - using peak/sum(spectrum) calculate a confidence level for that sample (signal/noise). 90%=perfect, 6% is pure noise (1/16). With good signal/noise this gives good decision criteria. This is the path I will continue playing with a low pass filter on confidence level to get better decoding in noise. And then is the next challenge. The most efficient way to match time stamps onto the alphabeth. Volhout P.S. as a test bed I use Youtube video's , and PLAY SOUND 1,sine wave, level and PLAY SOUND 2,noise,level from the sound output in pico. changing level of noise helps me defining decoding quality.

This is just curiosity, now that it is fixed. Re. the former bug in LINE command when using integer arrays or integer array elements. It wasn't all integer arrays, just those using % to denote type. I tried Dim Integer to set the type and Line worked properly. Curioser and curioser Edit. So for those using V5.08.00 which doesn't have the fix, its not really a problem if you avoid %.

The standard PicoMite firmware version 5.09.00b4 was flashed and compared to the previous versions it turns out that after a reset the port is immediately recognized with a beep and nothing appears on the terminal yet, but it is only released 6 seconds later with the following, which previously was almost immediately the was the case?

Version 5.09.00b5 https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip Puts a block on OPTION LCDPANEL CONSOLE n where font n would result in less than 30 characters display width Enables defaulting caps_lock and num_lock in OPTION KEYBOARD lang [,capslock] [,numlock] In both case values of 0 or 1 are allowed specifying if the lock is on-1 or off-0. Default if not specified is caps-lock off and num-lock on In betas previous to 4 Ctrl-C or program end would disable framebuffers and restore FRAMEBUFFER WRITE to the main display b4 left the write status as-is. Seems like this confused some users who didn't see the cursor after ctrl-C if the write was to a framebuffer so b5 reverts to previous functionality Edited 2024-03-02 00:54 by matherp |

I'm sorry I posted problems with usb betas in the wrong thread. I switched back to PicoMite MMBasic USB Edition 5.09.00b2 as I couldn't get 00b3 to do anything not even a terminal to set options. I just tried PicoMite MMBasic USB Edition 5.09.00b4 and set options but ili9431 not displaying anything so back to PicoMite MMBasic USB Edition 5.09.00b2 and all is fine. I don't know what I'm doing wrong. |

Please try b5. There was a problem with b4, don't know about b3, but b5 definitely works with an ILI9341 |

I just tried Version 5.09.00b5 picomite usb and options set but gui test lcd no display on ili9341. Back to 5.09.002 and all is fine again. I'm not a time waster, I report things not working. wish I could post happy days but having problems with 00b3 , 00b4 and 00b5, picomite usb ili9341, sorry. everything is the same except new firmware. stan |

Have you done an OPTION RESET in b5 or entered all the options from scratch? If not, please could you try this. Otherwise you will have to stick with b2 for the moment. I don't currently have a properly working ili9341 but the one I have with a cracked screen is definitely showing something with GUI TEST LCDPANEL |

Happy days after option reset??? it seems ok.display ok,touch,sd card. thanks for sorting it.v00b2 was fine. stan I tried vgaUSB 00b5 and that seems ok now. Edited 2024-03-02 06:50 by stanleyella |

Peter, If I only apply voltage to the USB connector with a 5V adapter in the latest version, the Raspberry Pi Pico never starts running and the LED remains off. Also does not start if connected to TeraTerm (PC beeps twice) and the correct COM port has not yet been selected, the LED remains off. Option RESET doesn't help either. Only when the correct com port has been selected in Tera Term will the flashing LED start. When there is only voltage on the module, the LED remains off. Also tested with clearing memory with Clear_flash.uf2 with no changes. PicoMite MMBasic version 5.09.00b5 Copyright 2011-2024 Geoff Graham Copyright 2016-2024 Peter Mather > Jan |

Yes, same for WebMiteV5.09.00b5 |

Which board(s) are you using? The Pico should always power up using its own USB or via a supply on either pin 39 or pin 40 (which is the same as the USB supply). If the heartbeat LED isn't flashing after loading the firmware then it's probably either not loaded or buggy. Try an earlier version. If you have it set up with a USB system then remember that you can't load firmware via the USB-TTL converter. That doesn't work. Disconnect all sources of 5V before connecting the PC lead to the Pico's USB connector to load the firmware. This is important.

IMPORTANT: This does not refer to the USB version but to the normal b5 (in my case, `WebMiteV5.09.00b5.uf2`) I am using here Pico W - it worked fine with b2 before. Yes, but it doesn't. It boots when it is able to initiate a COM link, but not with a USB power supply alone. Does not blink; does not boot (or gets stuck, I cannot tell). b2 works fine; haven't tested b3 and b4. EDIT: I did not download b3 and b4, and they seem not to be available anymore Yes, thanks. This is not about the USB version. Best Thomas Edited 2024-03-02 19:12 by karlelch |

I have 5.08 working properly on a Webmite. I've not tested anything later on it as I don't need to for this job, I don't think. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
