This is what I'm talking about:
paying $5/device sold seems like a good choice when I don't know if I can sell more than 50pcs, now the only option is to pay the full licence. Please tell me if the new pricing is fixed, because I need to consider if I will take a different path.

Hi!
The first time I saw uGFX (about a year ago) there was the possibility to make a commercial use of it paying a inexpensive fee for each unit sold with the uGFX on it, now this possibility is gone?

After many hours reading data in the scope and comparing the behaviour of this with the Mbed library, I get it to work!
The main difference is the Mbed library after each sequence of data it puts the CS line to high level (releases the bus), that is not the case of the uGFX lib for ILI9341 (at least on the init sequence, which is what I used to compare), so I added the code at the end of the transmission function on the board file, and it works
For those who can be interested in using this combination of tools for this screen/microcontroller, I will attach the relevant files.
To generate the project I used CubeMX, enabling SPI1 and some pins for CS, RST, DC ( D10, D9, D8 on the right side of the nucleo board), mixed this with the project generated in Eclipse and followed the procedure on the uGFX wiki to import the library.

hi Victor!
as far as I understand the getting started, I should use ugfx/gfxconf.h, my settings on this file are:
#define GFX_USE_OS_RAW32 TRUE #define GFX_CPU GFX_CPU_CORTEX_M4_FP #define CORTEX_USE_FPU TRUE #define GFX_OS_HEAP_SIZE 8192 #define GFX_USE_GDISP TRUE #define GDISP_NEED_CIRCLE TRUE #define GDISP_NEED_ELLIPSE TRUE #define GDISP_NEED_ARC TRUE #define GDISP_NEED_ARCSECTORS TRUE #define GDISP_NEED_CONVEX_POLYGON TRUE #define GDISP_NEED_TEXT TRUE #define GDISP_NEED_UTF8 TRUE #define GDISP_INCLUDE_FONT_DEJAVUSANS10 TRUE
Don't know about the HAL and CMSIS settings, probably I should check that.
ARCH is defined in Properties->C/C++Build->Settings->Tolchains is set to ARM(AArch32) and prefix is arm-none-eabi-I know nothing about these flags, should I worry?

Hi!
Thank you for the tip, but unfortunately I have no idea how to do that!
I should delete the entry in "Cross ARM C++ Linker"->Miscellaneous->Other objects I added: $(GFXSRC), then should instruct to the makefile to use arm-none-eabi-gcc instead arm-none-eabi-g++, but how?

Hello!
I'm trying since a while to integrate this lib into a project and begin to play with my screen (the 2.8" w/touchscreen ILI9341, similar to those who sell Adafruit). My setup is Linux mint KDE 17.3, Eclipse Neon + GNU ARM Eclipse, NucleoF401RE board, the project was created with CubeMX and imported according with the method of Carmine Noviello (I successfully draw some things in a SSD1306 OLED screen with the U8GLib trough I2C and DMA).
Since the Makefile is generated with some automake I make a makefile.init with this content:
GFXLIB = /home/jano/STM32Toolchain/workspace/ili9341-ugfx-uno/ugfx include $(GFXLIB)/gfx.mk
In project properties->C/C++Build->Settings->ToolSettings added the include path "../ugfx" for the sections "Cross ARM GNU Assembler", "Cross ARM C Compiler" and "Cross ARM C++ Compiler", in "Cross ARM C++ Linker"->Miscellaneous->Other objects I added: $(GFXSRC)
The methods in board_ILI9341.h seems to have nothing to do with the errors I have, I can comment everything and nothing new happens.
This are some of the results of the compilation in the console:

do I missing to include something? or should tell something more to the compiler? any ideas? Thanks for reading.
STM32F401 + ILI9341 + Eclipse (GNU MCU Eclipse) + CubeMX + uGFX <-- Working!

Posted · Edited by jano
no, a library I found in Mbed works out of the box (for a old version of Mbed OS), then I used this to compare his behaviour (measuring with the oscilloscope) with the behaviour of the project I generated with the GNU MCU Eclipse + CubeMX and followed the instructions on the wiki of uGFX to integrate it on an Eclipse project.
I wanted to have this working on Eclipse because of the better debugging possibilities.
I was changing the parameters in the main.c (attached on the first post) on the init section of the SPI until the numbers I read on the oscilloscope where the same as in the init sequence for the screen (frequency, polarity, etc.), for that reason these parameter can differ from the ones in the ioc file I will attach now, the valid parameters are the ones in the main.c
Is important to have the right parameters in the SPI init, but even when this is correct and the numbers where the same all along the init sequence for the screen, it doesn't work until I added the order for releasing the bus at the end of each transmission. I think this should be corrected on the driver to avoid unnecessary instructions here, the driver I have of Mbed releases the bus between every data-cmd sequence.
