  1. This is most likely a mismatch of the color formats. Check the color format configuration of your GDISP driver (eg. /drivers/gdisp/RA8875/gdisp_lld_conf.h). It defaults to RGB565. You have to ensure that the display controller on the other end is using the same color format as specified in the GDISP driver configuration.
  2. I think you need to read the first few basic articles of our documentation such as this [1] and this [2] to understand things like what a module is and how to enable or disable modules. [1] https://wiki.ugfx.io/index.php/Architecture [2] https://wiki.ugfx.io/index.php/Configuration
  3. Hi, Unfortunately, we never worked with CubeMX enerated Makefiles ourselves. However, there are plenty of community members that did this successfully. As it's Makefile based you should definitely be able to just follow the official Makefile guide that you quoted in your post. Maybe someone like @cpu20 could help here (he's this community's IDE expert).
  4. That sounds an awful lot like an issue in / related to the GDISP driver that you're using. You can use the GDISP TestStub driver to compile & run with that. It's an empty driver that doesn't do anything but allows to pass compilation of the GDISP module. This way you can ensure that the rest of the system is running properly.
  5. You're using an older version of the library. We'd recommend using the latest master branch of the official repository or getting the latest stable v2.9 release from the downloads section.
  6. Hello & welcome to the µGFX community! Did you include the "gfx.h" header in the files where you call the high-level API functions such as gdispDrawPixel() ?
  7. Thank you for sharing your driver We'll look into the forum upload issue that you mentioned.
  8. Have a look at the various GWIN (and widgets) documentation. Especially the /demos directory that comes as part of the library might be a valuable resource. the /demos/modules/gwin and /demos/applications applications will demonstrate the proper use of the event system to dispatch widget events.
  9. Thank you for bringing this to our attention. We've added looking into this to our ToDo list.
  10. The µGFX-Studio is currently not available for any kind of use in a production environment and/or commercial use. This is indicated on the µGFX-Studio download page.
  11. There's a list of all supported controllers on the website/homepage. You can also have a look at the /drivers directory. And as @inmarket said: Adding a new driver is very easy. There's documentation and plenty of existing samples including drivers for very similar display controllers.
  12. There's currently no driver for the ST7920 display controller that comes with the µGFX library but µGFX is very agnostic: It will work with virtually anything. There are plenty of existing GDISP drivers (also for monochrome displays) that you can use as examples to implement your ST7920 driver.
  13. The STM32F103 is quite an outdated microcontroller. Any particular reason why you'd be using this model? µGFX will definitely work in all of those configurations. How much RAM you want to have to work with is of course another discussion (and your personal decision). µGFX can work with very little resources. Having more resources available just enables you to do fancier stuff.
  14. Happy to hear that you got it working! The issue with the chip select sounds like the GDISP driver is not properly calling those functions.
  15. Hi, We appreciate your motivation to donate. Once we started selling commercial licenses we decided to take down the donation option. Money is clearly the main hold-back issue here as we can't afford more man-power but donations usually don't result in an amount and steady supply of money that would allow to improve this. We're close to release µGFX v2.9. It's already ready - we just need to do the actual release. µGFX v3.0 is also making progress
