    I have been trying to make RA8875 with SPI to work with emWin, but not much success. This far all but Edit, MultiEdit, Checkbox and text work fine, although the colors must be right. You can see the problems in the attached file. The basic text example works only if I select the colors right, otherwise the text is as in Edit box, blurry. Only GUI_TM_TRANS | GUI_TM_REV seems to show the text always ok. Checkbox does not work. I can check and uncheck a checkbox and read the state, but it is always…

  • Hello Sven, thank you for your reply and sorry, that attachment was missing. Your code is for parallel 16 bit bus, but I am using 8 bit SPI and I think the problem is there. I have been doing some new tests and also reading more manual and below is the situation I am now in. Manual33.2.3 Indirect interface - 4 pinSPI (p. 1168) Normal SPI is 4 pin, clock, MISO, MOSI and chip select, emWinSPI is aspecial case, it has dedicated line for C/D and no data read line.

    In my case it is in this way. Here I am using STM32F407 and FSMC. In SPI I use DMA to send the data vector. I think LcdReadDataMultiple is never used, so also an empty function will do. PortAPI.pfWrite16_A0 = LCD_WriteCom; PortAPI.pfWrite16_A1 = LCD_WriteData; PortAPI.pfWriteM16_A1 = LCD_WriteDataMultiple; PortAPI.pfReadM16_A1 = LCD_ReadDataMultiple; /******************************************************************** * * LCDWriteDataMultiple * * Function description: * Writes multiple values t…

  • I have been trying to get RA8875 with SPI to work with STemWin, but not fully succeeded. All others seem to be right, but the texts in edit boxes and other editable widgets are really small. It will not help, if I change the size of the font. The layout is made by GUIBuilder. Also I have not been able to find any combinations of settings for 65K colors, only 256 colors work, The attachment is in 256 colors and not very nice. Any ideas how to proceed?
