  1. Thank you so much for the help. It worked beautifully! If you don't mind, may I ask where did you include the file system_stm32f7xx.c?(Only asked because I would love to learn from my mistakes). Also, this example does not compile a demo, rather uses the main.c and gfxconf.h. How to overcome this? (I understand the flexibility provided by having a main instead of a separate demo, would just like to learn more.) Once again, thank you very much! Next step for me would be to get a livefeed from a camera module running on the board LCD. Any ideas which ugfx submodule would be best suited for this task?
  2. Hey Sorry to say, but it still won't compile. I am unable to solve the previous error. Which makefile did you modify and how?
  3. I understand that these are not uGFX related errors. Thanks a lot for helping me out. I am new to embedded development on STM microcontrollers. I am grateful to you for all the help and support. Where to include tha file system_stm32f7xx.c? I tried including it inside of stm32f7xx_hal_rcc.c but that resulted in a multiple declarations error! Inclusion trials in other files yielded similar errors. Please help me out if possible. Thanks
  4. Thanks for the prompt reply, @inmarket! Jumping from one bug to next, we got a new one now. Got this error now. Really starting to get annoyed at ST. Attaching my compilation example directory with the build files as well as the STM include files I am using. Please have a look if possible! Thanks a lot! STM32.zip
  5. Hi Sorry for the delay in update. That commit fixed the previous problem. Great! But now I am getting another error. Have a look: Seems like there are some more problems with compatibility. To attempt a workaround for this error, when I changed __IO to extern at line 25 in the file ugfx\boards\base\STM32F746-Discovery\stm32746g_raw32_system.c I got the following error: Sorry to bother you yet again. Really appreciate the excellent support that you guys are providing for the library. This was compiled using Cygwin on Windows 7. Please have a look and do tell if you find anything. Thanks!
  6. @sp9fkpDid you manage to solve/workaround the problem? I am also using STM32F7 Discovery and ran into the same problem. If you know of any workarounds/solutions/fixes/patches, please do share. Thanks!
  7. Hi I managed to solve the previous error regarding missing definition of LSE_STARTUP_TIMEOUT. Turns out a minor edit in HAL configuration files did the job. Now when I compile using cygwin, I am running into these strange errors. Searching your forum for previous instances led me to However, that thread did not mention any solutions for the STM32F746 Discovery. One more question, what is meant when they said Did they mean changing HTML_COLOR_R to HTML_COLORR or did they mean something else? I really need to make it work, and any solution will work. Please help if possible. I am attaching screenshots for the compilation process. Have a look: Using Cygwin on Windows 7. I am attaching my project's zip file which was placed in the root of ugfx directory. STM32 includes are also there in the zip itself. In case you have run into this error before or have a known workaround, please do help. Thanks a lot! example_raw32.zip
  8. Hi, Thanks a lot for your support. Appreciate your dedication and commitment towards the project! I got the program to compile successfully using Cygwin, but when it is uploaded to the board, nothing happens on the LCD. It just stays blank white, whereas it should be running the demo. I have tried changing demos, changing paths, changing locations and verifying the makefile. The upload process is successful, I have tested it using the demos available in the downloads section(pretty awesome). There is some problem with the files or some other options. I am wondering what might be the issue. If you have any idea or have encountered this problem before, please help if possible. Once again, thanks! I began afresh after installing Cygwin and followed these steps: 1. Edited the respective makefiles located at ugfx/boards/base/STM32F746-Discovery/example_chibios3 and for the example_raw32 for paths 2. Compiled the programs using cygwin, after including all required STM32 files, as indicated missing during compilation. The chibios3 example compiles absolutely fine, but when I upload the hex file to board, there is no response. Nothing happens. The upload finishes and that's it. Life goes on, and the board does not come on. When I compile the raw32 examples using cygwin, these errors show up: Please have a look if possible. I am attaching a zipped version of my ugfx working directory. The compilation examples are located in root of directory. Please try and help if possible! Thanks a lot! ugfx.zip
  9. For reference, a picture of the errors and warnings in Eclipse.
  10. Hello I am new to uGFX and ChibiOS and have been trying to get a uGFX demo working on my board ( the STM32F746 Discovery). I am using latest ChibiOS(3.0) and working inside of ChibiStudio Eclipse IDE. Before making the changes for including uGFX inside of uGFX via Makefile edits, the program compiled and ran perfectly fine(it was the simple LED blinking demo for ChibiOS). After making the changes, I removed the ChibiOS's original main.c file inside directory(as required). Then, the makefile and gfxconf.h were edited as given on the Getting Started and ChibiOS/RT wiki pages. The modified files are attached below for reference. Now, when I try to build the project using Eclipse(on Windows), the following errors show up: 1. make: *** No rule to make target 'ugfx/demos/modules/gwin/basics/demo.mk'. Stop. 2. target 'build/obj/gdisp_lld_STM32LTDC.o' given more than once in the same rule. I have been trying to debug this for the past two days, but to no avail. Please help if possible. Thanks! gfxconf.h Makefile
