 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. |

Is your Pi 64-bit capable? If so, the 64-bit Raspberry Pi OS is very stable and runs great. You can write it to a new microSD card, pop out the 32-bit card, plug in the 64-bit card and try it. If it doesn't work or you just don't like it, pop out the new card and pop in the old, 32-bit card and continue as if nothing happened! That's the great thing about having the OS on a removeable drive. 64-bit Raspberry Pi OS |

Hi Tom, It's a Pi 3 which I believe is 64-bit capable, but with only 1 GB memory hardly worth it. In any case porting MMBasic to Linux is consuming all my hobby time at the moment so re-compiling GFXterm, whilst still something I want to do, is currently on the back burner. Best wishes, Tom Game*Mite, CMM2 Welcome Tape, Creaky old text adventures |

compiled within a 32-bit linux VM, had minimal testing - though there is no good reason it should not work: GFXterm32 (4-sept-2021).zip cheers, rob :-) Edited 2021-09-04 19:48 by robert.rozee |

GFXterm32 tested on Lubuntu 16.04 x86 (no updates since first install, so really old). Works nice. No problems encountered. I was surprized it worked so well on this old laptop, and that it is compatible. I even created a .desktop file for it so it shows in the menu. I'll keep this one on the old machine. Thanks, Volhout PicomiteVGA PETSCII ROBOTS |

Rob You kindly released the source for GFXterm back in July, and I have built it on my RapsberryPi 32 bit - ok. I noticed that a later update fixes a major bug! Will you release the source again with the bug fix? I just now actually got it to crash, but don't know what I did!!! Sorry. Also, uploading a file is VERY slow due to delays you have introduced per line of text, undoubtedly warranted. Have you considered putting xmodem into the program? The source is readily available. Thanks, I like it. led Miss you George |

hi led, here is the latest source (as of today): GFXterm source (2021-09-21).zip and here are Linux32 and Linux64 executables: GFXterm32_64 (2021-09-21).zip NEW FEATURE: now compiles for Win32, and more-or-less kind-of works. uploading should be fairly quick using AUTOSAVE, i just checked a 52k basic file and it took around 47 seconds uploading to an MX170. however, pasting directly into the editor is far slower. the delays are to ensure no on-screen corruption occurs, especially important when pasting into the editor. i have been considering adding xmodem, in particular for downloading basic from the micromite in an automated fashion (ie, GFXterm senses an xmodem transfer starting, captures the data, and then asks where to save it too). will need to read up on how doable this is, and figure out a 'nice' way of adding the functionality. please DO post your compile for RPi, and let me know if this version has any crashes or other problems. i've been continuously simplifying how comms are handled which seems to be improving reliability and reducing CPU load. cheers, rob :-) Edited 2021-09-21 00:37 by robert.rozee |

Here is GFXterm for Raspberry Pi Buster 32bit OS GFXterm32-armhf.zip Little testing so far, but seems ok. Had a small problem compiling with a change you made to remove warnings! (an '@' char in front of a Buff[1] - seemed to make a big difference here!) Anyway, have included some extras for those that use the Pi to get them settled in with few hassles. A 64 bit version will follow. Thanks again led Miss you George |

GFXterm for Raspberry Pi Buster 64bit OS (Beta) GFXterm-arm64.zip Rob GFXterm-arm64 compiles but does not identify any COM ports when run. By selecting the "edit" checkbox and inserting a valid COM port in the "CONNECT" config menu, eg /dev/ttyACM0, the program is then quite happy and communicates with my Pico board. The Lazarus install, on a Beta 64bit Raspberry Pi OS, appears to be missing modules for the arm processor (not real sure though what's going on). Lazarus 2.0.0+dfsg-2 & FPC Version 3.0.4 As the OS is only Beta and Bullseye is coming to the Pi soon I will not do any further testing as I don't use the 64 bit OS normally. Others may want to try this though. Thanks once again led Miss you George |

an interesting problem. can you possibly check the following works? ls /sys/class/tty/ this should give you a list of all the serial port names that exist. the list should look something like: console tty16 tty26 tty36 tty46 tty56 tty9 ttyS16 ttyS26 ttyS8 ptmx tty17 tty27 tty37 tty47 tty57 ttyACM0 ttyS17 ttyS27 ttyS9 tty tty18 tty28 tty38 tty48 tty58 ttyprintk ttyS18 ttyS28 ttyUSB0 tty0 tty19 tty29 tty39 tty49 tty59 ttyS0 ttyS19 ttyS29 tty1 tty2 tty3 tty4 tty5 tty6 ttyS1 ttyS2 ttyS3 tty10 tty20 tty30 tty40 tty50 tty60 ttyS10 ttyS20 ttyS30 tty11 tty21 tty31 tty41 tty51 tty61 ttyS11 ttyS21 ttyS31 tty12 tty22 tty32 tty42 tty52 tty62 ttyS12 ttyS22 ttyS4 tty13 tty23 tty33 tty43 tty53 tty63 ttyS13 ttyS23 ttyS5 tty14 tty24 tty34 tty44 tty54 tty7 ttyS14 ttyS24 ttyS6 tty15 tty25 tty35 tty45 tty55 tty8 ttyS15 ttyS25 ttyS7 GFXterm runs the following check function across the above list: // method based on information obtained from the following two sites: // https://www.lazarusforum.de/viewtopic.php?p=72837 // https://stackoverflow.com/questions/2530096 function CheckDevice(DeviceName:string):boolean; // checks to see if the device named is a live var DriverName:string; // ... serial port. this is done by checking FD:longint; // ... entries in /sys/class/tty, including the SS:TSerialStruct; // ... presence of a link to a device driver. ST:stat; begin Result:=false; ST.st_mode:=0; if (DeviceName<>'.') and (DeviceName<>'..') then if FileExists('/sys/class/tty/'+DeviceName+'/device/driver') or DirectoryExists('/sys/class/tty/'+DeviceName+'/device/driver') then if fpLstat('/sys/class/tty/'+DeviceName+'/device', ST)=0 then if fpS_ISLNK(ST.st_mode) then begin DriverName:=ExtractFileName(fpReadLink('/sys/class/tty/'+DeviceName+'/device/driver')); // writeln(DeviceName,' : ',DriverName); if DriverName<>'serial8250' then Result:=true else begin // writeln(' checking serial8250 device'); FD:=fpOpen('/dev/'+DeviceName, O_RDWR or O_NONBLOCK or O_NOCTTY); if FD>0 then try if fpIOCtl(FD, TIOCGSERIAL, @SS)<>-1 then if SS.typ<>0 then Result:=true; fpclose(FD) except end end end end; for a device you know exists, you should be able to follow down the tree: /sys/class/tty/DeviceName/device/driver and even do the following to get the driver name thus: user@DH61BE:/sys/class/tty/ttyUSB0/device$ user@DH61BE:/sys/class/tty/ttyUSB0/device$ user@DH61BE:/sys/class/tty/ttyUSB0/device$ user@DH61BE:/sys/class/tty/ttyUSB0/device$ ls driver port_number power subsystem tty uevent user@DH61BE:/sys/class/tty/ttyUSB0/device$ readlink driver ../../../../../../../../bus/usb-serial/drivers/cp210x user@DH61BE:/sys/class/tty/ttyUSB0/device$ which tells us (in this case) that the device is a SiLabs CP2101. btw, am a portion of the way towards getting XModem running. i have it plumbed in so that when you press f11 or f12, GFXterm triggers on the micromite text response (XMODEM RECEIVE or XMODEM SEND) and jumps to a routine that will pop up load/save file dialogs and do the transfer. cheers, rob :-) Edited 2021-09-23 02:13 by robert.rozee |

Rob Been all over that code, looks good (it compiles for a 32 bit system doesn't it!). The OS has everything in place for the code to work, Lazarus install is questionable. Headaches with the nuances of a different language, a different IDE (and did I say that I hate "floating windows" - yes getting old) I couldn't get the debugger working, although my interest had waned by that stage. Maybe an ubuntu 64 bit install for the Pi may do a better job, don't know... Sorry, but I'm done for now  led Edit: Maybe another go with xmodem in it Edited 2021-09-23 06:41 by led-bloon Miss you George |
