 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. |

The in-built MM+ firmware takes 14 seconds to display the attached 800x480 image of a tiger saved as a .BMP on a SSD1963 display. 
The attached code takes just 2 seconds to display the same image, saved as a binary portable pixelmap (.PPM), at the same resolution and same colour depth. Any semi-decent photo software will be able to save images as .BMP and .PPM. Make sure to choose the binary option for the .PPM files. This code uses the MX170 loadable SDcard driver configured for the Micromite+. The loadable SDcard driver uses the PetitFAT software which is much lighter weight than the Microchip SD stack. Also the .PPM image files are easier to interpret than .BMP. The code posted is configured and tested on a 100-pin Micromite with a SSD1963 display configured as usual with OPTION LCDPANEL. To use on a 64-pin version substitute the pair of CFunctions that are commented out in the code. The code has been tested on 4.3", 5", and 7" SSD1963 displays. The use of the loadable SDcard driver is compatible with normal use of the in-built SDcard routines in the MM+ so you can still use "FILES" etc. and just use the driver for faster load of images. Alternatively you can use the loadable driver functionality as explained in this post The code includes slideshow functionality for all .PPM files found on the SDcard. To display a single image just use the command DisplayPicture "image.ppm",0,0
The two zeros are the x,y coordinates of the top left of the picture. i.e. the syntax is the same as "LOAD IMAGE" Of course the CFunctions and the Displaypicture routine can be stored in the LIBRARY to reduce their footprint. Option explicit

It is too big to post. Just right click the image above and save it. Then use any photo program to convert it to a binary .PPM |

I am using coreldraw X10 and it doesn't have the PPM option to save it., possible to email me ? robertquaas@163.com Thanks RQ |

Robert has just discovered that some graphics programs do not add a comment in the .PPM header which my program assumed. The attached DisplayPicture routine fixes this. Please substitute this update in the above program '***************************************************************************************************
' ' Display a picture from the SD card on SSD1963 ' Picture must be in binary .PPM format ' ' Parameters are: ' PIC$ = filename of the picture to be displayed ' StartX% = X coordinate of the top left of the picture ' StartY% = Y coordinate of the top left of the picture ' ' Note: the routine checks that the picture is not too big for the screen and reports an error if it is ' Sub DisplayPicture(PIC$, StartX%, StartY%) LOCAL Buffer$,addbuffer$ length 3 LOCAL Result%=-1 LOCAL NumBytes%,a%,i% local integer buff(511) SDcard fileopen,PIC$ 'Read the first 128 bytes Buffer$=STRING$(128," ") SDcard readfile,buffer$,0,len(buffer$),NumBytes% a%=instr(buffer$,chr$(10)) ' look for the first CR if left$(buffer$,a%-1)="P6" then buffer$=right$(buffer$,len(buffer$)-a%) if left$(buffer$,1)="#" then a%=instr(buffer$,chr$(10)) ' look for the second CR buffer$=right$(buffer$,len(buffer$)-a%) endif a%=instr(buffer$,chr$(32)) ' look for the space between dimensions local width%=val(left$(buffer$,a%-1)) buffer$=right$(buffer$,len(buffer$)-a%) a%=instr(buffer$,chr$(10)) ' look for the third CR LOCAL height%=val(left$(buffer$,a%-1)) buffer$=right$(buffer$,len(buffer$)-a%) a%=instr(buffer$,chr$(10)) ' look for the fourth CR buffer$=right$(buffer$,len(buffer$)-a%) a%=len(buffer$) mod 3 addBuffer$=STRING$(3-a%," ") ' we need to make sure we have a number of bytes divisible by three in the buffer SDcard readfile,addbuffer$,-1,len(addbuffer$),NumBytes% buffer$=buffer$+addbuffer$ if (StartX%+width%>MM.HRES) OR (StartY%+height%>MM.VRES) then print pic$," too big", width%," x",height% else defineregionSSD StartX%, StartY%, width%, height% DisplayBufferSSD Buffer$ do SDcard readfile,buff(),-1,4095,NumBytes% if numbytes%<>0 then DisplayBufferSSD Buff(),numbytes% loop while NumBytes%<>0 endif else Print "Invalid File Format" endif end sub |

Hi Peter Thanks for the update. Now I have downloaded the BMP to PPM Converter from: http://www.contenta-converter.com All images converted from [BMP (800x480), 7" Touchscreen running 100pin Micromite] to PPM and clear and clean. The Contenta converter is trialware for 30 days for those who have interest in this thread. All the best and thanks again. Robert Q |

Try XnView as a simple Photo assistant tool. When you add it's shell extension, XnShell, it has a lot of common tasks in it's right-click context menu. Not a replacement for PS or Corel, but very useful & quick to use tools. It has PPM; don't know about the header, just a check box labelled ascii in the PPM options. Phil. |

Peter This line [quote]const SD_CS_PIN = 47 'Connection to CS on SD card[/quote] Does this pin HAVE to be 47 or can it be 52? The reason I ask is I've been using your "Big Ben" code and it's connected to pin 52 on the pcb I've been using and it works fine, just about to test this but not sure if I'll have to mod the pcb or not |

@matherp I have been looking at this topic , an old thread I know but do you have the source code available, as I would like to cobble together a version to work with my CPLD display. I assume the version in the thread is purely for the SSD1963. Is there any advantage in using PetitFat over the standard SD routines in the MM+ E100? Trevor. |

| matherp Guru Joined: 11/12/2012 Location: United KingdomPosts: 10570 |
The MM+ used to use the Microchip SD card routines which were slow. Recent releases have migrated to FatFS so this thread is now redundant. The only way to go faster is this thread which you already know about and includes source |
