For me, this is fantastic video, just full of techniques to reduce memory requirements and improve performance, with very little effect on the visual appeal of the UI ... Mille Grazie!
Hello Mr. Mauro thanks for the video. It's a very nice video. You touched on important issues. Could you also share information about SPI FLASH, External Loader and SPI1 configuration? Have a nice day.
Hello, I will use stm32 and st7262 driver. I couldn't find a sample library on the internet. Has anyone done this before or can give me ideas on how to do it?
That was an F411. STM32F1 doesn't support TouchGFX. You can find a list of uC that can run that graphic system here: support.touchgfx.com/docs/development/hardware-selection/hardware-components/hardware-selection-mcu
Thanks for your great guides & information. I've just created my first GUI using TouchGFX and it worked well. Are you aware of a way to remove a background image from a widget? (i.e make it "No Image") My background image has the gauge background embedded, so I dont need it in the gauge/meter. I have used a transparent background at the moment in each item, but looking at this video it might affect my file size depending on which colour format I'm using.
In such a case I load the project with a "dummy" image of 1x1 pixel of the backgroud color and I use it in gauges that have to be transparent. "Dummy.png", that could be even transparent, will be shown in the top left corner of the gauge. In the project you see in this video there are two gauges overlapping (the first - on the back - has the color arc, the second - front - shows just a pin). Both gauges have a 1x1 pixel background (the same "dummy.png") allowing a below background image to be shown. I hope this helps.
Hi Mr.Mauro. How can I activate the callback function to implementing the tick timer for TouchGFX? Just enabling the timer 2 in the STM32CUBEIDE? I did it but didnt work.thanks, best regards
Yes, I started the timer. I´m using stm32f429. May I use another timer instead TIM3? The void HAL_TIM_PeriodElapsedCallback (TIM_handleTypeDef *htim) didn´t appear in the z_displ_ILI9XXX.C library
@@fernandoprudencio5521 Callback is just at the end of z_displ_ILI9XXX.c file. It refers to the TGFX_T macro parameter on top of z_displ_ILI9XXX.h in order to have just 1 area to modify, setting up a project. It is also controlled by DISPLAY_USING_TOUCHGFX macro (again on top of z_displ_ILI9XXX.h) in order to avoid mistaken handling if not using TouchGFX. So: setting up a timer with its ARR and PSC, enabling interrupt, setting also above parameters and turning on timer on main, everithing should go.

Glad to see that you find useful my work.
You did not include Test_T.c to the library. Can you explain how to send data from sensor to display ? Any examples ?

keep in touch

Hi Mauro! What micro are You use ??? Stm32F1?? Good videos!!Greats from Argentina

I also have ili9341 but I'm using ESP32. Do you have tutorial for this TFT with ESP32?
I'm sorry, I'm not using ESP32 since a long time.

Handling timer shouldn’t show too much surprises. Did you start timer?

Also perfekt for me, with F411 mpu... I also have an L476 Nucleo, I think it should work, maybe even better, with the ART function??
Let me know the result of your tests!
Thanks
👍
