Hello , everyone.
I have a module which is uLCD-32PT,but I canât display any image from the uSD card or write a file to the card.
My operation is as follows:
Firstly , I used the â RMPET Rev1.1 â to partition the uSD card and then formatted it to Fat .
Secondly , I used the GC3 to build two .jpg photos(100x100 resolution) into the uSD card , the â Build Type â is â 4DGL,SGC Picaso-GCI-FAT Selected Folder â and I named it â 1 â (you can see 1.Gci in the displayshort of the uSD card) . Besides , I also copy other files which is needed for some scripts.
Thirdly , I used the â FATCONTROLLER â to display the image in pan>â 1.Gci â , but the result made me confused . The following is the message of the log:
Version 0.000 [56 00]
4DRom file not found, cannot simulate Display
Get Status 0.000 [7A]
Init uSD 0.234 [40 69]
Get Status 0.000 [7A]
Display Image Icon Fat 0.000 [40 6D 31 2E 47 63 69 00 00 00 00 00 00 00 00 00]
Display Image Icon Fat 0.016 [40 6D 31 2E 47 63 69 00 00 00 00 00 00 00 00 00]
Display Image Icon Fat 0.015 [40 6D 31 2E 47 63 69 00 00 00 00 00 00 00 00 00]
Erase Display 0.406 [45]
Erase Display 0.406 [45]
Erase Display 0.015 [45]
Erase Display 0.031 [45]
When I click the â display image â button , the response is âNakâ with nothing change on the display , but when I click the button for the second time ,the response is âAckâ and the image on the display is strange .Then I click the â Erase â button , the response of the first two clicks is â No responseâ , but the third click made the strange image blue and the forth click cleared the display.
Finally , I tried to run some scripts , and the âGraphics Pt1.4DScriptâ worked well ,but all the scripts relative to uSD card didnât work . I also changed the uSD card (kingston) but the result is the same.
Besides, I also made an attempt to follow the procesures from the document------4D-AN-1002-Displaying-an-Image-Using-the-FAT-Controller-for-SGC-Modules-rev1.pdf . It seems all right until the last procesure , though I got an âackâ response , there is nothing change on the display.
I donât know whatâ>s wrong . Is there any obvious mistake above?
I will appreciate for any response.
