 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. |

This release of the firmware has a number of significant new capabilities. 2017-01-30_144811_Micromite_eXtreme_Manual.pdf 2017-01-30_140238_MMX5.3b10v9.zip Text output in all orientations It supports text output in all four orientations + vertical directly from Basic on all supported displays including VGA. This is achieved by simply including the orientation in the justification string so: text 100,100,”ABC”,ICM will output ABC inverted with the string centered on 100,100 horizontally and vertically. Valid codes are N(ormal), I(nvert), U(p), D(own) and V(ertical)  Automatic GPS data input and NMEA decoding It supports automatic decoding of NMEA input from a GPS. This is simply activated using OPEN "COMz:baudrate" as GPS [,timezoneoffset] The timezone_offset parameter is used to convert UTC as received from the GPS to the local timezone. If omitted the timezone will default to UTC. The timezone_offset can be a any number between -12 and 14 allowing the time to be set correctly even for the Chatham Islands in New Zealand (UTC +12:45) Once the GPS is "opened" the function GPS will give immediate access to individual parameters GPS(ALTITUDE) returns current altitude if sentence GGA enabled GPS(DATE) returns the normal date string corrected for local time e.g. “12-01-2017” GPS(DOP) returns DOP (dilution of precision) value if sentence GGA enabled GPS(FIX) returns 0=no fix, 1=fix, etc. if sentence GGA enabled GPS(LATITUDE) returns the latitude in degrees as a floating point number, values are –ve for South of equator GPS LONGITUDE) returns the longitude in degrees as a floating point number, values are –ve for West of the meridian GPS(SATELLITES) returns number of satellites in view if sentence GGA enabled SPS(SPEED) returns the ground speed in knots as a floating point number GPS(TIME) returns the normal time string corrected for local time e.g. “12:09:33” GPS(TRACK) returns the track over the ground (degrees true) as a floating point number GPS(VALID) returns: 0=invalid data, 1=valid data. ALWAYS CHECK THIS VALUE TO ENSURE DATA IS VALID BEFORE USING OTHER GPS() FUNCTION CALLS Sensor fusion for applications needing orientation information It supports automatic calculation of pitch, roll and yaw from 9-axis sensors allowing applications like a tilt-compensated compass to be programmed entirely in Basic - code attached below watch the video  Measurement of unknown input baudrates It supports a new function BAUDRATE which will report the baudrate of an active serial input on any of the comms ports Paged display for 4.3" SSD1963 It supports the 4.3" SSD1963 display using a new driver SSD1963_4P This sets the 4.3” SSD1963 display up in 480 x 864 (landscape or reverse landscape) or 864x480 (portrait or reverse portrait) pixel mode. The screen viewport is 480x272 or 272x480 and the position of the viewport is controlled by GUI STARTLINE n. This mode of operation allows display updates to be done on a non-visible part of the graphics memory and then the viewport moved to see the updated image completely eliminating tearing effects. The 4P display controller is fully compatible with TOUCH, MOUSE, CURSOR and GUI controls. and is used in the compass program Arrays as inputs to drawing routines It supports arrays as inputs to the basic drawing routines. This can provide huge speed improvements in some cases. For example outputting individual pixels in a loop can achieve 22000 pixels per second. Using arrays to contain the pixel coordinates speeds of over 400,000 pixels per second are possible. More details of the new functionality are included in the Micromite eXtreme manual attached above. Errata Any bugs in Geoff's 5.3b10 beta release for the MM+ will probably also be in this code. Other bugs are entirely my own creation.

I find all this a bit hard to believe. AWESOME. 6 years ago I built a MICROMITE and now I'm here. Paul. "It is better to be ignorant and ask a stupid question than to be plain Stupid and not ask at all" |

Very useful and easy to use "extended" functions. Great work Peter  . |

Indeed. The Micromite just keeps getting better and better with chaps like Geoff and Peter working on the development. Impressive new features for the eXtreme family. Smoke makes things work. When the smoke gets out, it stops! |

Peter, Terrific job - can't wait for WW's board to arrive. P23 of your manual SPS(speed) should be GPS(speed)? Regards, Doug. ... almost all of the Maximites, the MicromMites, the MM Extremes, the ArmMites, the PicoMite and loving it! |
