Hi All I wonder if anyone can suggest a solution to the following - Some weeks ago I successfully got the bigben clock running on an explore 100 and ssd 1963 screen using matherps code and the 100 pin cfunction attachment - it adorned my office computer and kept correct time -without a problem- I was even brave enough to experiment with different clock faces downloaded ,reduced in size to fit the 480 by 480 pixel size of the display and converted to BMP files I was absent from my home for some weeks and the setup sat idle for that time- upon return - having made sure I had the clock code safely stored away - I used the explore 100/ tft display for another purpose - the oil pressure gauge with the blit command operating the pointer - some days later I reinstalled the bigben code - and now find the hour hand behaving in a strange fashion- when the code is first run the time is displayed correctly (with the RTC installed)until the second and minute hand reach the 12 o,clock position at which time the hour hand flicks back to the last hour position- I have removed the RTC thinking the internal clock may be faulty but on running the code without the RTC - the hands all immediately go to the 12 o,clock position indicating the normal internal clock default - 00:00:00 - 1 JAN 2000 about 1 second later the hour hand jumps to the 1 o,clock position , the second and minute hand behaving normally- 1 hour later - with the minute and second hand at the 12 o,clock position - the hour hand jumps back to the 12 o,clock position - this cycle repeats itself endlessly I have printed the internal clock time when the display shows the hour hand in the incorrect position and the time returned as a string is correct - meaning the clock hands are not reading the internal - or the RTC when fitted, correctly the hour hand can be forced to read correctly - for 1 hour anyway - by leaving teraterm connected and when the hour hand flicks back to the last hour - re running the code using F2 - this then displays the hand in the correct position - for 1 hour at least I was wondering if anyone could suggest a solution to this weird problem on another subject - is it possible to remove individual OPTIONS if one wishes to remove items in the OPTION list - or is it necessary to use OPTION RESET and then rewrite all the required options again- and another - is it possible to draw a line using the LINE command, pause it for say 900ms, then erase that line and redraw it in another position - as in the second hand of the super clock- all against the background of a nominated colour so as to appear like a revolving second hand Ive tried using the LINE command and the CLS RGB but the time taken to redraw the line after clearing the screen to a colour and then redrawing the line makes the display appear very "flickery" - as its obviously possible to achieve - would anyone be able to provide the code snippet for that function many thanks oldtimer |

Yes - you can remove individual OPTIONS (or directly change them in some cases) OPTION .... DISABLE will delete certain OPTIONS such as LCDPANEL SDCARD, RTC etc You will need to DISABLE them rather than just change them using 'new parameters'. For example, if you set up the TFT but incorrectly type a pin number, th OPTION will be saved with whatever you typed in (i.e. the wrong pin number). To change to the correct pin number, you will need to DISABLE the OPTION first (to remove it from the list), and then re-enter the correct/new parameters. Some OPTIONS are changeable directly i.e. on the MMX, OPTION HEARTBEAT can be switched between ON and OFF (i.e. without the need to DISABLE first) Hope this makes sense  WW For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

One trick is to simply draw the line in the background colour to effectively erase the line - much quicker than a CLS For everything Micromite visit micromite.org Direct Email: whitewizzard@micromite.o |

WW - option disable command working fine - many thanks - still playing with erasing single line at 1000ms intervals to display sweep second hand - again thanks oldtimer |

you draw over the old hand to when you draw the new hands as short as possible to reduce flicker. If you precalculated the new positions and saved the results for old and new before drawing over the old ones, there would be less flicker but I am happy with the above code as it is.

This sub precalculates the new positions. Visually, there is little difference. VK7JH MMedit MMBasic Help |
