 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. |

V5.07.07b11 - specially for Volhout  https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip New capabilities for PEEK function peek(bp n%) ' returns the byte at address n% and increments n% to point to the next byte peek(sp n%) ' returns the short at address n% and increments n% to point to the next short peek(wp n%) ' returns the word at address n% and increments n% to point to the next word These make it very efficient for basic code to step through a packed array e.g. dim s$="123456" a%=peek(varaddr s$)+1 'point to the start of the string data for i%=1 to 6 print peek(bp a%) next i% PIO DMA TX and PIO DMA RX now allow up to &HFFFFFFFF transfers Edited 2023-02-01 20:49 by matherp |

Gentlemen and Matherp I am new to this forum and have encountered something strange after version V5.07.07b5. I am using self-compiled code partly from this forum for an i2c scanner which worked well until V5.07.07b5 and after V5.07.07b7 it stops working and stops at I2C Read i,0,1,temp. Error : Cannot find Temp. And system crashes and ** Fatal Error ** What am I doing wrong or has something changed in the firmware?

I translate most of the time because my English is not very good and "Translate" is my best friend and the actual code is English. For example, I translated the PicoMite Basic manual into Dutch for myself with many examples and additions. (>360 pages so far) and also the PIO course by Volhout (172 pages) Jan Volk |

Welcome to the forum. Your English is much better than my Dutch! You need to define the temp variable before using it. dim temp After that, your code runs on the latest beta firmware. Jim VK7JH MMedit MMBasic Help |

This happens after running Volhout's Logic Analyzer. >files Error : Not enough memory > option list The same as Volhout also pointed out in an earlier post. Was this something that you also wanted to address in the latest update? I just updated the firmware to the latest version (Option list says b12; download says b11). PicoMiteVGA MMBasic Version 5.07.07b12 OPTION FLASH SIZE 4194304 OPTION COLOURCODE ON OPTION KEYBOARD IT OPTION CPUSPEED (KHz) 378000 OPTION DEFAULT MODE 2 OPTION DISPLAY 60, 106 OPTION DEFAULT FONT 7, 1 > /Pluto |

Jim, I tried with Dim temp and the first time it worked, but by re-running several times I get an error and reset the program and even ** panic ** Edit no longer works. Can only be fixed by re-flashing program, but problem in firmware is still present. Previously temp was probably automatically declared? JanVolk |

What happens if you go back to an old MMBasic? Does it then work? John |

John, See my first post. With PicoMite MMBasic version V5.07.07b5 everything worked fine. Then the problems started. Raspberry Pi Pico is my first microcontroller with MMBasic and have been using it for a year now. JanVolk |
