Peter has released V5.07.06 of the PicoMite and PicoMiteVGA firmware (V5.07.05 was skipped). This release is an update to both versions and fixes all currently known bugs. However the outstanding new feature is the Flash Filesystem. In case you have missed Peter's beta test versions this looks like a normal disk drive to MMBasic and is automatically created by the firmware using the spare flash memory in the Pico. Data and programs can be read/written using the normal BASIC file commands (SAVE, RUN, OPEN, etc) and sub directories can be created and deleted, long filenames used, etc. This is a major feature and is worth the upgrade. Peter has done a tremendous job  The changes are listed in the release notes and both user manuals have been updated and now include change bars to highlight the new material. The new firmware and manuals can be downloaded from: PicoMite: https://geoffg.net/picomite.html PicoMiteVGA: https://geoffg.net/picomitevga.html Upgrading the firmware will erase the program and programs stored in the flash slots and clear any options set. So save everything first. Geoff Edited 2023-01-07 11:35 by Geoffg Geoff Graham - http://geoffg.net |

Thanks as always to Geoff for a huge amount of work on updating the manuals. The release notes for 5.07.06 are in the download but are reproduced below. Updating to this new release is highly recommended. PicoMite V5.07.06 Changes from V5.07.04 Breaking changes PicoMite PAGE command removed - replaced by GUI PAGE GUI TEXTBOX ACTIVATE removed Reduced available RAM and program size from 120KB to 116KB Removes support for the GDEH029A1 display as this controller is now obsolete Breaking changes PicoMiteVGA Reduced available RAM and program size from 108KB to 100KB General changes - both versions Various tuning and performance improvements Updates SDK to V1.4 Updates Compiler to version 11.2.1 Enables operation up to 378MHz SETPIN for PWM no longer needs to specify the channel and port e.g. "SETPIN 1,PWM" is now accepted Re-engineering of PORT command to allow simultaneous update Modifies the port function to read all pins simultaneously Revised version of CSub header to cater for compiler change Updated CSUB header file and additional functions exposed The number of flash slots in both versions is now 5 Changes the priority of the CIN.FIN,PER interrupt to improve accuracy Resets default fonts when a new program is loaded or the NEW command is executed. Max editor clipboard size now 16384 characters Max number of BLIT buffers now 32 (memory dependent) Support for file system on the Pico's flash. All SD file commands are supported. Flash drive is "A:" SDcard if configured is drive "B:" By default the system restarts with the active drive as drive "A:" even if the SDcard is configured On first installation the firmware will automatically create the flash drive. The firmware reads the size of the flash and uses this to determine the drive size. Flash chips > 2Mb are fully supported OPTION LIST now shows version number and which firmware Changes to better support modules with >2Mb Flash chips PWM duty cycles can now be negative which will invert the output (-100.0 <= duty <=100.0) New/changed Commands - both versions DRIVE drive$ - sets the active drive DRIVE "A:/FORMAT" - re-initialise the flash drive MATH RANDOMIZE [n] - seeds the Mersenne Twister algorithm. TRIANGLE SAVE [#]n, x1,y1,x2,y2,x3,y3 - saves a triangular area of the screen to buffer #n. TRIANGLE RESTORE [#]n - restores a saved triangular region of the screen and deletes the saved buffer. MEMORY PACK source%(),Destination%(), number, size - packs the contects of one array into another MEMORY UNPACK source%(), Destination%(), number, size - unpacks the content of one array from another BITBANG SERIALTX pinno, baudrate, ostring$ - transmits ostring$ on pinno BITBANG SERIALRX pinno, baudrate, istring$, timeout_in_ms, status% [,nbr] [,terminators$] - receives istring$ on pinno ON PS2 interrupt - triggers an interrupt whenever the PicoMite sees a message from the PS2 interface. OPTION HEARTBEAT ON/OFF LINE AA x1, y1, x2, y2 [, LW [, C]] - Draws a line with anti-aliasing. FRAMEBUFFER - see manuals for details OPTION SERIAL CONSOLE TXpin, RXpin [,B] - adding the "B" parameter means output will go to "B"oth the serial port and the USB PIO READ - Allows a single integer variable to be used when nbr=1 New/changed Functions - both versions MATH(RAND) - returns a random number 0.0 <= n < 1.0 using the "Mersenne Twister: A 623-dimensionally MM.INFO(drive) - get the current active drive - returns A: or B: MM.INFO(HEAP) - returns the free space on the MMBasic heap MM.INFO(STACK) - returns the C program stack pointer MM.INFO$(SOUND) - returns the status of the audio channel MM.INFO(PS2) - returns the last raw PS2 message received. MM.INFO(PINNO n) now accepts a literal, a string variable or an unquoted GPn designation MATH(CRC8 array()_or_string$, [length,] [polynome,] [startmask,] [endmask,] [reverseIn,] [reverseOut] - calculate an 8 bit CRC MATH(CRC12 array()_or_string$, [length,] [polynome,] [startmask,] [endmask,] [reverseIn,] [reverseOut] - calculate a 12 bit CRC MATH(CRC16 array()_or_string$, [length,] [polynome,] [startmask,] [endmask,] [reverseIn,] [reverseOut] - calculate a 16 bit CRC MATH(CRC32 array()_or_string$, [length,] [polynome,] [startmask,] [endmask,] [reverseIn,] [reverseOut] - calculate a 32 bit CRC PIO(EXECCTRL jmp_pin ,wrap_target, wrap [,side_pindir] [,side_en]) - JMP PIN must have GP designation, Extra optional parameters Other new functionality - PicoMite Enabled BLIT and LOAD JPG for mono displays BLIT LOAD: now also accept BLIT LOADBMP for compatibility with VGA version Adds support for the 480x320 IPS ILI9481 display (use code ILI9481IPS) Other new functionality - PicoMiteVGA Use EDIT 1 to edit in mode 1, Use EDIT 2 to edit in mode 2, Use EDIT to edit in current mode Implements DRAW3D command and function Improved LOAD JPG for MODE 1 (mono).

Just.... WOW! Many thanks, Peter, this is sterling work on your part as usual. This really has become a habit of yours. :) Many thanks also to Geoff for his excellent work on the manuals. I've been watching the development of 5.07.06 but until now I hadn't realised just how much has gone into it.

Thanks Peter, thanks Geoff! Sorry I have to report a bug in the manual page 73  Actually it should be: MM.INFO(FILESIZE file$) That makes more sense too. BTW. the transfer speed (copy a: to a:) is 63.5 KB/s on my 16MB-Picomite (Clone). Best regards Michael |

Thanks Peter and Geoff for all the time and brain power you have put into this. Also on VGA only PWM invert doesn't. > setpin 1,pwm > setpin 2,pwm > pwm 0, 67, 50, -50 same as pwm 0, 67, 50, 50 |

Sincere thank you's for all your hard work- I've found these devices to be wonderful time savers for the kind of stuff that I do on a regular basis. In reading through the manual and other docs, I found a couple of minor items- 1. There are two of more references to the PIC32 in the Manual. Do a search. Not a big deal but a small confusion. 2. The explanation of how sound works in the background is somewhat confusing. Page 32- Play Tone 500,500,2000 End It makes some sense that this doesn't work. You then add the pauses- this I guess is still "non blocking" or is it? You go on to say just below that this applies to PLAY WAV as well. I would think that you'd use the interrupt in the original invocation to jump some where when that sound completed and the next should start. I'm going to play with this a bit tonight but I'm not sure its crystal clear what is going on. 3. I'm dying to play with the PIO stuff. I've played with this in the Python version and got it do some things. I'm an old assembly programmer so this really dear to me. I'll do some testing on the PIO stuff in the coming days. I'm going to try to hang a nice I2S DAC on it to play high fidelity sound. I'll post my results. This is a cool version- I like the internal file storage support as well as the very complete SD Card Support- wonderful. John Wettroth |

That will teach me to do last minute updates. Geoff has uploaded fixed versions to his site. You will know you have the new versions as the copyright is also updated to show 2023 Sound commands are non-blocking. The issue is that when a program ends with an END command or Ctrl-C it stops the audio output so unless you wait before exiting you will never hear anything. Likewise executing PLAY TONE twice in rapid succession will replace the first tone with the second such that the first may never be heard. Ending a program by "running off the end" without an explicit END statement will not stop the audio. Otherwise you would not be able to execute sound commands at the command prompt.

@Peter I think I found a small bug regarding MM.Info(FILESIZE file$). I wanted to use it to determine whether a file exists. From manual: I would expect a return of -1 for a nonexistent file, but I get: Error : Could not find the file I know I could deal with "on error skip" and "mm.errno". I also know that there are two other ways to determine if a file_exists. MM.Info(MODIFIED fb$)="" and On Error Skip Open "file.txt" For Input As #1 If MM.ErrNo <> 0 Then ... Best regards Michael EDIT: I was surprised! Question regarding the copy command: Is it a desired behavior that files with the same name are not automatically overwritten/replaced, but have to be deleted first?

Hi Peter, Sorry, another bug. :-( Using VGA with options:- PicoMiteVGA MMBasic Version 5.07.06 OPTION SYSTEM I2C GP22,GP15 OPTION COLOURCODE ON OPTION KEYBOARD UK OPTION DEFAULT MODE 2 OPTION DISPLAY 80, 160 OPTION SDCARD GP5, GP2, GP3, GP4 OPTION AUDIO GP6,GP7, ON PWM CHANNEL 3 OPTION RTC AUTO ENABLE OPTION F6 Edit 1 OPTION F7 Edit 2 OPTION DEFAULT FONT 8, 1 The Mode 1 screen is only 620 wide, height is good, similarly the Mode 2 screen is only 310 wide, as in, if I draw past these values they are off screen, the whole width seems to be stretched.
