  2. The imagebox should automatically redraw when necessary. The only thing you have to make sure is that the image remains opened. The imagebox widget will simply clear the area if the assigned image is not opened (i.e. "nothing" will be rendered).
  3. Hi all, I have an ImageBox in a container. The image related to this ImageBox needs to be loaded from a memory card. GFILE is already working. My doubt is: is there a way to make the image be drawn automatically everytime the container is shown, or should I draw the image manually in this case? Thanks in advance.

  5. Indeed I can download the file now. I think it was a temporary problem. Thank you very much for your help! Ronald Wijnsema
  6. We're happy to help where we can - don't hesitate to ask on the forum. I assume you're referring to the attachment of a few posts above yours? I had no issues downloading it. I've re-attached it to this post. Let me know if the issue persists.ArduinoIDE_ESP32_ILI9341.zip
  7. I would love to try this library but it seems to have a rather steep learning curve. Hope to be using this lib, most popular one I found (bodmer TFT_eSPI) is not async proof and does not support multiple displays. The ArduinoIDE_ESP32_ILI9341.zip project looks very promising since this is precisely the hardware I'm using. However, the file was removed. Can anybody get hold of it? Thanks!

    When will Studio be available? I looked in the downloads section and in various places, but didn't see it.
  9. I want use ugfx studio for cortex-M4 board, thank you!
  10. Hi, I am very interested in getting Beta Access as I am preparing an lab for real-time programming languages for the summer term at my university. Thanks in advance!
  11. That should definitely go into a separate topic :)

    Can't implement GADC

    I did it. I found that the ADC values should be passed as a parameter "rawvalue" to the function DialCallback(gU16 instance, gU16 rawvalue) called by poll timer. Dial attached to sliders works ok. From ADC as well as from encoder. Now new question. May be not for this topic. How to do text string controlled by dial? Something like frequency readout. I think there is only one way. This is Label. But label can not be attached to simple variable in memory as dial and toggle to objects. Maybe there is an elegant way to do this?
  13. I have the STVA070WT-01 model https://www.stoneitech.com I am testing with an arduino leonardo, or uno. I also have a max3232 rs232 serial to ttl adapter to connect the display to the arduino. Also have not looked up what pins to connect this to yet if anyone knows. I want to know how to send a variable to the screen to display it. can have some one to help me getting this stone hmi screen running?
  14. Thanks for the update Joel, cheers
  15. The µGFX library is actively maintained. There is currently no release date for µGFX v3 as we want to put our best efforts into it. The development repository of v3 is not public hence there's very little publicly visible efforts. µGFX v2.9 is known to be stable. While we do not currently add new features to it we are applying patches & hotfixes as they appear. We can only recommend using the µGFX library in your commercial product 😉 If it helps: There's an equally named company behind the µGFX library - This is not just a floating piece of software. Also professional support is being handled through this company.
  16. Hi there, I'm just wondering about progress towards v3. The uGFX site says "actively developed" but there hasn't been any substantial commits for 8 months (besides a comment fix a week ago). We're hoping to use uGFX in a commercial product if possible, but we're scared to use a library that will not be actively maintained. Any update would be appreciated! Thanks, Joshua
  17. Hello, I am new to this ufgx I want to use this Library and it's tool too. I want to Design a GUI with a drag & drop builder. currently Im using roger's Arduino_STM32 core and Adafruit_ILI9341_STM.h for my tft lcd. Can anyone suggest me how to use this ugfx.
  18. Generally you would read the analog input in the dial driver directly. GADC is designed for when you have a single ADC device with multiple inputs, some of which you want to use for high speed sampling e.g. for audio, and some for low speed sampling such as dial devices. There is currently only one GADC driver, for the SAM7 cpu which has a single ADC that reads 8 input lines simultaneously. GADC is then required to pick off samples at low frequency from sampling that is occurring much faster say for the purpose of GAUDIO. If you are not in such a circumstance GADC is probably overkill and the dial input analog input can be read directly in the dial driver.
  19. I launched a widgets demo project on STM32F429 Discovery board. Successfully added GINPUT TOGGLE for external buttons. But can't add support GADC analog input to control slider. ADC initialized by calling gadc_lld_init(). This is done. Dial attached successfully by gwinAttachDial(ghSlider1, 0, 0); . It returns TRUE. ginput_lld_dial_poll(DialCallbackFn fn) called periodically with GINPUT_DIAL_POLL_PERIOD. gadcLowSpeedStart(GINPUT_DIAL_DEVICE0, samplebuf+0, GADCCallback, (void *)fn); called by ginput_lld_dial_poll(DialCallbackFn fn) (taken from example). Raw data from ADC in samplebuf. Of course it doesn't work. Questions: 1. GINPUT_DIAL_DEVICE0. Is this just number of instance and can be any custom number? 2. GADCCallback. Is this any custom user samples post processing function callback? 3. gadc_lld_nontimerjobI(&pdata->job); called by gadcLowSpeedStart(gU32 physdev, adcsample_t *buffer, GADCCallbackFunction fn, void *param) and it seems must capture data from the ADC. It calls only one time after start. Generally, i don't understand where is a point to input raw data from ADC. What should I do to control the slider from external analog input?
  20. This was fixed in commit ff93884f71f783627f196330fd0c9f6a639bee56.
  21. I have finally had a chance to check the line in question. That line is never used - it is a comment put in for use by the documentation system doxygen. You can see the corresponding conditional compilation on line 132. The line that actually gets used is the block of macros between line 304 and 313 for true color pixel formats. So, in a proper compile it will correctly generate the color mapping.
  22. Hi Joel Bodenmann, Thanks for your help. It was really helpful.
    Thank you very much, it really helps. Zip itself could use some weight reduction because there's a lot of unnecessary files.
  23. Hello & welcome to the µGFX community! It would be definitely very appreciated if somebody could update the demo
  24. Hi I think demo is hard to complete as per https://wiki.ugfx.io/index.php/Using_ChibiStudio. Problem is that demo configuration of ChibiOS (176) and downloadable versions of ChibiOS (182, 191) are not compatible. Anyone willing to share an updated demo? /Peter
  25. Hello & welcome to the µGFX community! This is certainly possible. The graph widget demo also plots multiple values in the same graph. However, in this case you'll most likely just end up having more than one graph widget/window on the same "display page".
  26. Hi, I’m currently working on a Patient Monitoring Project. I need to know whether I can make this kind of multi-chart in a single window as seen in attached image. I’ve done a single chart in a window using uGFX but can we do multi-chart using uGFX??.
