I edited the first one about autorun on, makes no difference. Ops looks I missed the first mention of autorun, autorun is not a problem. The last post is 3 commands from the command prompt at power up, you can see the error. There is no program loaded or running. Mike. NANO Inverter: Full download - Only Hex Ver 8.1Ks |

Jim I got it going: All I had to do was this: Put Chdir "R:/" as the first command before checking the current directory with CWD$. In Geoffs Basic this is not needed as CWD$ returns the current directory straight away. NANO Inverter: Full download - Only Hex Ver 8.1Ks |

You can also do CHDIR "." That way it won't change any existing folder location. Jim VK7JH MMedit |

Yes I've actually gone with CHDIR ".." to go to the root. I have a generic function for creating directories if they don't exist, and not changing directories if I don't need to. But it's interesting that the Current directory string CWD$ is not being initialised at start-up as it is in all versions of MM.Basic that I've used on the MM-100. My first command was always where am I? using the contents of CWD$. Mike NANO Inverter: Full download - Only Hex Ver 8.1Ks |

When I do a port I start by commenting out all code that won't work on the new platform, then as I implement the features one by one I either re-instate or replace the code as required. I left in a commented SD card initialisation on the CWD$ function  Should work now: 2018-10-02_170533_Armmite1.3.zip As Jim explains, in order to save command tokens I've removed all the deprecated Basic statements like WHILE/WEND. It should give a better error but the problem is that WHILE is still a valid keyword just not in that context. No: the only advantages of the 8-bit drivers are that they are RGB888 rather than RGB565 |

Yes I guessed that WEND had been dropped and it only took a few minutes to convert. Like I said, everything is running great, screen is perfect and I only mention the things I find like CWD$ in case it was an oversight, and again, an easy work around, thanks again for all the ongoing work and the updated files.

Please do raise everything you find. The attached should give a better error message with WHILE for which thanks to Geoff who sent me the code change to properly get rid of WHILE/WEND 2018-10-02_195332_Armmite1.3.zip |

Thanks again, and I will be using these for all my projects from now on. So slightly off topic - but - the program I wrote for the MM-100+ that controls what is basically a dual axis CNC with 3 steppers and SYNC generating and decoding of two Digital positioning slide scales went across with only the pin numbers changed in the header constants for the 25 I/O pins and dual PWM channels. I just wired up the two Digital scale slides and they worked perfectly first time, the speed difference in timing and sync clock generation is like night and day between the 120 MHz MM-100 and this thing, it absolutely flies. I spent almost 2 days mapping every pin on a large colour print out of the two main board headers, so once done, pin selection for the 25 I/O pins literally took seconds. No conflicts, every port works first time and I'm just blown away, glad I stuck at it. Thank you again for all the effort that is going into making this Armmite such a fabulous platform for Geoffs wonderful MM.Basic and the effort in porting it across and getting this device working with it.

Latest Armmite1.3.zip NOTE: If you put the card back in while it's locked, the CTRL-C prompts suddenly reappears and/ or the EXIT button will now work. Option default none Option explicit Font 4 GUI BUTTON 2,"EXIT",100,100,80,100,RGB(white),RGB(RED) DO IF TOUCH(REF) = 2 then END TEST_SD() LOOP SUB TEST_SD() local TMP as string on error ignore TMP = CWD$ on error abort END SUB Without an SD card this locks the system and only a reset will get it back to the prompt - CTRL-C will not work OR plug an SD card back in. I've updated the code make it easier to test. Take out the GUI and it will run without locking. NOTE It's not just CWD$ but Chdir will do the same, anything that tries to see if an SD card is present without crashing to the prompt won't work, it works in the MM-100. Hopefully someone else can try this and confirm. EDIT: It also needs to be in a Procedure for it to lock, does not lock in the main loop as easily. NANO Inverter: Full download - Only Hex Ver 8.1Ks |

You have tight loop Put a pause in the main loop and it works OK. Without the PAUSE, there is no time to check the console/keyboard. Jim VK7JH MMedit |

I had a longer pause in there initially, but stripped everything out that was not needed, in my system I can CTRL-C out first time every time without any pause. I've changed the code I posted to show how it appears to hang without the SD card but starts working once a card is inserted. Like I said - I need to check for a card error without crashing to the prompt, I've been doing this for ages, now it no longer works. NANO Inverter: Full download - Only Hex Ver 8.1Ks |

My version loops happily and prints 123 without the SDcard inserted and 123 and the CWD with it inserted. RUN 123 123 123 R:/ 123 R:/ 123 R:/ 123 > Output when started without the SD card then continues when the SDcard is inserted. Jim VK7JH MMedit |

Need more info. What is the objective here? I can understand a single test at the start of a program as to whether the SDcard is inserted but to continue to check over and over again? Are you using CD? It would be possible to create a system variable MM.SDCARD that gives the status of the SDcard rather than the coarse technique of trying to access it. Checking the SDcard is easy enough if CD is wired. If it isn't you have to send a command and wait for a response or timeout. This wastes processor time so I have only set this to happen every 65536 Basic statements. |

This is a tiny crappy test program to show that trying to check if the SD card is working causes the program to NOW appear to hang until a card is inserted. !: The SD card is ONLY checked ONCE in the main program and normally bring up a message box alerting the user that the SD card cannot be read. 2: It ONLY appears to hang if GUI elements are declared. 3: I'm using the SD slot on the LCD. 4: In the previous version I got my message box if the card was faulty or removed. 5: In the latest version I don't, it never get to the message box because it sits somewhere in MM.Basic until a SD card is eventually inserted OR reset is pressed.

Look like I was wrong I didn't check with no card on the previous version. So the only solution is to just plug in a card or a new card and wait for whatever is happening outside of the main program to see a card, and then it returns back to the next line in the main program.

The last word on the SD card - I promise. I did a rewrite of the main SD check code so that swapping the SD card from the MM-100 into an Armmite and back the other way always works even though the drive letters are different. First off, I realise that the following would likely not happen if I had a card detect line on the LCD SD slot. The same complete application is running on both units: MM-100 with CD Disabled for this test. MM-100 no SD card: Pops up a program message box with an error (takes about 2 seconds to appear) click OK and the program opens with default set-up values. Armmite no SD card: Will sit forever inside the Basic interpreter and will never come back to the next line. HOWEVER: Every so often on a restart it will continue and bring up the program Message box. Both the Armmite and MM-100 handle a newly formatted SD card with no files or directories. They both open the correct message boxes and make the missing directories and setup files as needed. NOTE: The SD program code runs with "ON ERROR IGNORE" and checks for errors accordingly. There is never a dump to the prompt no matter what the error. On exit from the SD code "ON ERROR ABORT" is set. So it's all good, I'll get an small SD reader with CD and use it instead of the LCD unit, which is not that good at holding the SD card anyway. NANO Inverter: Full download - Only Hex Ver 8.1Ks |
