 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. |

V5.07.08b5 https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip Changes to WebMite as per this thread Other new functionality. The MID$ command can now insert a string that is a different length than the selected section Full, optional implementation of regular expressions in INSTR and LINSTR INSTR([start],text$, search$ [,size]) LINSTR(text%(),search$ [,start] [,size] In both cases specifying the size parameter causes the firmware to interpret the search string as a regular expression. The size parameter is a floating point variable that is used by the firmware to return the size of a matching string. If the variable doesn't exist it is created. e.g.  Other changes: Fixed bug in MM.INFO(OPTION ANGLE) returns an incorrect value Fixed minor bugs in CALL and MM.CMDLINE$. LOAD SPRITE no longer requires exact spacing of the width,number,height fields. Fixed issue where changing volume when PLAY TONE is playing the same on both channels causes one channel to disappear. Fixed bug where EXECUTE command does not work at the command prompt Fixed bug where CLS after NEW when a framebuffer is active can crash system. Fixed bug where using EXECUTE in a program that has been AUTORUN crashes the system. |

I am seeing some issues with the new regex version of the INSTR function. I have tried a clean and reload of the b5 firmware but can still get the same results. There are a number of ways it manifests. This shows it working as expected after power restart, but relies of the INSTR function nominating the START position to be run first.

Peter, I was able compile/build PicomiteVGA only after adding "regex.c" to CMakeLists.txt ;) add_executable(PicoMite regex.c https://github.com/UKTailwind/PicoMite-VGA-Edition/blob/main/CMakeLists.txt |

V5.07.08b7 https://geoffg.net/Downloads/picomite/PicoMite_Beta.zip Fixes bug in FRAMEBUFFER COPY to N. Fixes bug in FRAMEBUFFER CLOSE. PIO DMA TX now accepts 0 for the number of conversions when using a ringbuffer for continuous output. NB: completion interrupt can not be specified when continuous operation is enabled PIO DMA RX now accepts 0 for the number of conversions when using a ringbuffer for continuous input. NB: completion interrupt can not be specified when continuous operation is enabled |

Note for Volhout I've just updated the download (11:57 UTC). Now when you specify continuous operation the array no longer needs to be aligned (no need for DMA MAKE RING BUFFER command). Just specify a standard array of the required size |

Just tested without MAKE RING BUFFER, that works fine for the sine wave generator. Volhout PicomiteVGA PETSCII ROBOTS |

Here are some notes for using the new Regular Expression options. MMBasic Regex Syntax used in INSTR and LINSTR functions. The alternate forms of the INSTR() and LINSTR() functions can take a regular expression as the search pattern in the Picomites from V5.07.08b6. The alternate form of the commands are: INSTR([start],text$, search$ [,size]) LINSTR(text%(),search$ [,start] [,size] In both cases specifying the size parameter causes the firmware to interpret the search string as a regular expression. The size parameter is a floatingpoint variable that is used by the firmware to return the size of a matching string. If the variable doesn't exist it is created. As implemented in MMBasic you need to apply the returned start and size values to the MID$ function to extract the matched string. e.g. IF start THEN match$=MID$(text$,start,size) ELSE match$=”” ENDIF The library used for the regular expressions “implements POSIX draft P1003.2/D11.2, except for some of the internationalization features”. See See http://mirror.math.princeton.edu/pub/oldlinux/Linux.old/Ref-docs/POSIX/all.pdf section 2.8 for details of constructing Regular Expressions or other online tutorials if you are not familiar with them. The syntax of regular expressions can vary slightly with the various implementations. This document is a summary of the syntax and supported operations used in the MMBasic implementation. Anchors ^ Start of string $ End of string \b Word Boundary \B Not a word boundary \< Start of word \> End of word Qualifiers * 0 or more (not escaped) \+ 1 or more \? 0 or 1 \{3\} Exactly 3 \{3,\} 3 or more \{3,5\} 3,4 or 5 Groups and Ranges (a\|b) a or b \(…\) group [abc] Range (a or b or c) [^abc] Not (a or b or c] [a-q] lower case letters a to q [A-Q] upper case letters A to Q [0-7] Digits from 0 to 7 Escapes Required to Match Normal Characters \^ to match ^ (caret) \. to match .

Thanks for the documentation. We will include it in the next manual. Another good use is to substitute sub-strings in strings using the new flexibility in the MID$ command e.g.  |

I believe this to be a bug: > option list PicoMite MMBasic Version 5.07.08b7 OPTION SYSTEM SPI GP6,GP3,GP4 OPTION AUTORUN 1 OPTION CPUSPEED (KHz) 252000 OPTION LCDPANEL ILI9341, RLANDSCAPE,GP2,GP1,GP0 OPTION GUI CONTROLS 2 OPTION TOUCH GP5,GP7 GUI CALIBRATE 0, 4034, 2040, -2600000, -64285 OPTION SDCARD GP22 OPTION AUDIO GP20,GP21, ON PWM CHANNEL 2 > list Do f% = Int(Rnd() * 500) + 100 Play Tone f%, f%, Int(3 * Rnd()) Loop > run [3] Play Tone f%, f%, Int(3 * Rnd()) Error : Sound output in use <---- after some random time Obviously this example is contrived for ease of reproducing the bug, but my understanding is that whilst consecutive PLAY TONE commands (without a sufficient PAUSE) will override each other rather than play consecutively they are still permitted without an ERROR.

You are calling play tone with no pause of any sort. It is likely that in the limit you are changing the tone before even one H/W interrupt has fired on the first call. This seems a completely unrealistic use-case and could well cause unexpected behaviour. If you can demonstrate the problem with a 1mSec pause between calls then I will look at otherwise not. |

You don't want real code, and you don't want contrived examples, you've a difficult man  .Try this: > list Dim noise%(200) Do For i% = 1 To 200 : noise%(i%) = Int(Rnd * 1000) : Next Do For i% = 1 To 200 Play Tone noise%(i%), noise%(i%), 2 Pause 1 Next Loop Loop > run [6] Play Tone noise%(i%), noise%(i%), 2 Error : Sound output in use The ERROR occurs after a random time. Sometimes instead of throwing the ERROR it will keep going but become silent. I know there are other ways of making noise, but PLAY SOUND is quiet unless you use all channels, and the approach above is the one that @Martin H used in the PicoVaders game that I am porting to Bintendo.

Hi Tom, Is it depending on CPUSPEED ? I recall you run the Bintendo at 252MHz. Volhout P.S. ran a trial with minimum frequency=1 (not 0), but the same observed. CPU=126MHz P.P.S. you can do without the outer DO:LOOP Edited 2023-07-04 17:07 by Volhout PicomiteVGA PETSCII ROBOTS |

Tom Explain this one  NB: CurrentlyPlaying is defined volatile Old code which gives the problem if(!(CurrentlyPlaying == P_NOTHING || CurrentlyPlaying == P_TONE || CurrentlyPlaying == P_PAUSE_TONE)) error("Sound output in use"); First diagnostic change if(!(CurrentlyPlaying == P_NOTHING || CurrentlyPlaying == P_TONE || CurrentlyPlaying == P_PAUSE_TONE)) error("Sound output in use %",CurrentlyPlaying); Prints "Error: Sound output in use 2" WTF: 2 is the code for P_TONE!!!!!! New code which is currently testing without error if(!(CurrentlyPlaying == P_NOTHING || CurrentlyPlaying == P_TONE || CurrentlyPlaying == P_PAUSE_TONE)) { if(CurrentlyPlaying != P_TONE)error("Sound output in use %",CurrentlyPlaying); } NB: the RP2040 does not have a data cache |

Hi, During execution of this code, there happens a sound interrupt, and the status changes. Volhout Edited 2023-07-04 19:14 by Volhout PicomiteVGA PETSCII ROBOTS |

| thwill Guru Joined: 16/09/2019 Location: United KingdomPosts: 4043 |
I wish I could. It looks like (excluding something crapping on the memory) it would require a thread/interrupt to change CurrentlyPlaying from an "invalid" value to P_TONE between the check and displaying the error ... and I can find no code that does that. You might try something like: e_CurrentlyPlaying tmp = CurrentlyPlaying; if (!(tmp == P_NOTHING || tmp == P_TONE || tmp == P_PAUSE_TONE)) error("Sound output in use %", tmp); But that is at best random hacking. Also no explanation for why sometimes the sound just stops completely .Best wishes, Tom Edited 2023-07-04 19:19 by thwill Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |
