No logo at power on... I start the debugger and take it step by step, the program goes through the "gfxInit();" command and then goes to the "gdispDrawPixel(10, 10, White);" command. I step into this command which finally leads me to the "drawpixel_clip(g);" command and then I get the hard fault error. I'll have a look again tomorrow. Thanks.

Hello again! So, I upgraded to version 2.9 but I still didn't find the "GFX_NEED_GDISP" definition anywhere, so I set the "GFX_USE_GDISP" to "GFXON". Anyway, the problem now is that any draw command causes a hard fault. The function call that generates the hard fault is in "gdisp.c" and it's "drawpixel_clip(g);". I don't know why this happens or how to fix it, so any help would be greatly appreciated!

I see I'm using version 2.8, so I'll upgrade to the latest one. Thanks!

So, compilation errors are all sorted out. Now I need to understand how to make ugfx know where my SPI interface is, as well as the reset and /CS signals. Also, I have a 3-wire SPI interface, which means I need to send a 9-bit word. Any help on this would be greatly appreciated! ?

OK, what I found out is that I copied the gfxconfig.h file to my project's SRC dir (as the installation guide for Keil said), but the compiler still reads this header file from its original location (where all header definitions are commented out). Now I got a bunch of different errors that I'll try to sort out. I have followed the instructions for installing ugfx in Keil, but it seems it's not working out for me or I have done some things wrong. I'll check it out and come back. Thanks everyone for trying to help me! ?

I don't see "GFX_NEED_GDISP" anywhere in my gfxconfig.h, but I have enabled this option --> "#define GFX_USE_GDISP TRUE".

Yes, "gfx.h" header is in "main.c"

Hi, I have a custom board with an SSD1322 OLED display and an STM32F103 MCU. I'm using Keil and have setup the ugfx. Everything is fine and I get a successful compilation when I include the gfxInit() command. But all other commands, like gdispDrawPixel or gdispFillCircle give a "warning: #223-D: function "gdispDrawPixel" declared implicitly" and "L6218E: Undefined symbol gdispDrawPixel (referred from main.o).", which means that these functions are not referenced. But I don't understand why. I have included in my project "gfxconfig.h", "gfx_mk.c", "SSD1322.h", and "gdisk_IId_SSD1322.c". I have also included the paths "..\ugfx" and "..\ugfx\drivers\gdisp\SSD1322". What am I missing?
